Seager Engineering provide machining services to classic vehicle owners, local motor-trade and industrial/marine companies. A comprehensive range of specialist engine reconditioning machine tools allows us to provide repairs and standard recon to a very high standard plus complex casting repairs. Services include:• Re-boring and re-sleeving of cylinder blocks and motorcycle barrels
• Crank grinding up to 60” in length
• Cylinder head/block facing with PCD/CBN tooling
• Valve seat work including lead free inserts
• Various crankshaft repairs
• Aluminium and cast iron welding
• Thread repairs by helicoiling, timesert or custom made
• Bearing housing re-sleeved to original postion and size
• Component supply for all modern leading brand engines
We supply spares for vintage and classic machines and manufacture our own for specialist applications. We also supply modern and classics motorcycle engine parts. Contact us for more details or go to our online shop. We have over the years provided industrial component reconditioning at both repair and re-manufactured level. We can work with companies to provide a remanufactured part on an exchange basis so lead times can be reduced including manufacturing the spares required in small batch quantities. Component material can be analysed to determine the type and quality so parts can be replicated or improved as required. Typical components are shafts, bronze bearings, pumps, both water and fuel injection pumps. Contact us for more details

We can offer prototyping machining services
either from scratch using a sketch, drawing
or altered from another part. Using all our machines we can machine and alter most
components and with our extensive experience and large
engineering contacts most things can be 'schemed' or
adapted/utilised from commercially available components. We can accept electronic files with drawings such as .iges or .dwg - email us for more information. Blasting your component to an 'as new' condition. Whether your component is fragile or robust we can can give a brilliant sheen finish to either ferrous or non-ferrous parts. This versatile process can give both a decorative finish, clean state and can be economically produced on a wide variety of used and new components. Ultrasonic Cleaning
Effortlessly cleans places you just can't reach. Ultrasonic Cleaning is regarded as a way of cleaning components which either have complex drillings or difficult to reach places. Using soundwaves to cavitate air bubbles in the cleaning fluid, you can clean delicate and complex assemblies effortlessly with virtually no component risk. Ultrasonic Cleaning
From carburettor's to cameras, crankshafts to clock parts, using a wide variety of fluids and temperatures and by adjusting the frequency great results can be achieved. We now have a BLASTWASH BTW1350 and a VIXEN JETWASH 600 Aqueous Hot Wash which is loaded with an applied chemical caustic degreaser which is made intentionally for aluminium. This cleans carbonised oil and dirt to a bright alloy finish. Stubborn dirt does need agitation but 80% cleaning is achieved within 10-20m cycle times. It is primarily used as part of the engine reconditioning process, we keep it regularly maintained and also use it for cleaning components and tools etc...

Many materials such as copper, brass, steel and cast iron can be accurately machined and silver soldered together for a stong and reliable joint, eliminating leaks of air/fuel or hydraulic pressure. SOFT SOLDERING: This process is mainly for small items where heat and distortion are to be kept to a minimum, examples include carbureter parts, decorative brass components, fuel or water pipes. SILVER SOLDERING: This process is highly underrated and if performed correctly provides an incredibly strong joint. Strict clenliness and joint preparation are essential but many items can be almost invisibly joined. broken/cracked cast iron is one material that responds well to this type of repair. BRAZING: Used for manufacture and provides an on-surface joint of reasonable strength many components are made by joining parts together and can be repaired by un-fusing, manufacturing a new section and re-joining. Our MUREX 375 SQUARE WAVE TIG WELDER allows us to weld aluminium castings or fabrications as well as stainless steel, aluminium/phosphor or bronze either in manufacture or repair. Other applications include stellite hard facing on rockers and other hard wearing parts, please contact for details. It also has a stick welding facility for cast iron, mild steel and stainless. With adjustable foot control for the amps and a fully adjustable current setting all materials can be welded. Seager Engineering has a wide experience in aluminium castings for classic bikes and cars as well modern cylinder heads. Components regulary repaired include: Crank-cases, cylinder-heads, gearbox casings, fuel pumps, bronze selector forks, fuel tanks and marine stainless steel fabrications. Hard facing using stellite is a cost effective way of reclaiming work wear pads and followers, we also have grinding facilities to re-surface back to original. Stick Welding
We can repair small cast iron parts with ease, but larger cast iron components require a more specialist approach and are best discussed on application. Please forward details for more information. On-site welding and fabrications can be arranged through one of our engineering partners. Services include hard facing, structural welding and fitting. MIG Welding
Our MIG welding capacity is mainly aimed at small fabrications and repairs but we can offer larger fabrications and on-site welding thru one of our engineering partners. Please contact us for details.

A good day always starts with a good breakfast but before that I had to prize the boys and the dogs out of our 5 star glamping beds… we hiked along a steep path past a deer snuggled up in the undergrowth to come out into the start of cheddar gorge.. I’m sure most of you have been here at one time in the past but for those in other countries who have never been here’s some pictures of the gorge and the caves… the first with all the multi coloured lights are in cox’s cave and the rest are Gough’s cave.
The gorge itself was carved by melting glacial water through the limestone rock at the end of the last ice age and the subsequent water from the top ran through tiny cracks in the Mendip hills to create these spectacular caverns..creating stalactites and stalagmites and and a river that ran to the gorge.. the water and sand dissolved and ground the rocks to form these caves and in turn provided a home to early man and one of the earliest remains of a British native was found here in Gough’s cave.. these caves as the glacier finally got smaller dragged with them thousands of tons of mud,rocks and debris to fill the caves and preserve them till Mr Gough in the 1800’s decided to excavate them and future excavation and mining created the path through to see the amazing limescale vaulted ceilings.. then a walk up Jacob’s ladder, 274 steps that make a old man legs drained of energy.. this is where me and the boys parted.., I took the short route down to the campsite for a beer and then a shower… they sweated it out on the long route… boy is it hot today.. we off to brean beach and a pint with a Beezer man at Weston super mare.. then back here.. a few bits and pieces to buy in the morning .. then trundle back to good old Suffolk .. then it’s back to work and lots of it !!😳😳😳😳

Hope you enjoyed the show so far!

Well the penultimate leg of our road trip is under way…. We said goodbye to to Devon and are on our way to Somerset… Joe my eldest is driving and he relies heavily on sat nav and as per usual his sat nav picks the routes in the shortest mode and drags us through roads that are sooo kin narrow that we had to fold in the wing mirrors🤣🤣🤣🤣🤣
When we get to cheddar I’m not sure if I will hit the chemist for Va**um or stick to the traditional relaxant…. A pint of beer!
Now travelling up the M5 and it’s slow but not thankfully stationary and have about 19miles to go… sat nav predicts 41minutes ….. I don’t remember journeys taking that long when I was young belting my 650 triumph around the West Country.. but then I didn’t seem to worry about speed limits and nor did the police…but traffic has increased in the last 40 years and you need much better brakes now nowadays as cars stop on a sixpence…
This next year I think my 1963 Bonnie will get a big big birthday…and get some serious use 😄😄😄😄
Back to the travelogue , we made it and it is spectacular..
The views and the accommodation ..
Loved the old Wolsey on the way up here…
Time to explore cheddar and see what’s on offer😳😳😳😳
I had to try the “ POTHOLER” 🤣🤣🤣😂😂😂

More updates from the seager engineering tour… after getting up early and having a good run with the dogs at Beer head, we headed of to Axmouth angling to replenish my stock of lures, yesterday I fished brandcombe beach for mackerel but only caught two and some very large garfish … but my fishing line has not been changed and I had two big hook ups only to be snapped off!!!
Talking to a local fella in the “Barrel of beer”,the mackerel run has almost been very poor but apparently off this coast has a run off blue fin tuna now and this fella I was speaking to a in the pub had photographic evidence of one he caught… no such luck for me ,But that is remedied now but no fishing as we’re off to cheddar this morning.
But yesterday we travelled to LF HARRIS LTD…. And Debbie Harris allowed us a tour around the workshop… they were currently making conrods and tappet adjusters and have recently bought a STAR SLIDING HEAD CNC LATHE…. very impressive indeed… the Conrod caps start of life as a forging and are machined on a Cnc mill as a pair ( one forging ) after the Conrod bolt holes are drilled and reamed then they are split.. the alloy part is machined on a separate mill and then bolted up and big end eye finished machined then orbitally ground for a precise size.. various other parts were being machined including the brake master cylinders and the bores were finally finished by roller burnishing the bore with a fully floating micro adjustable roller burnisher drenched in a heavy sulpurised cutting oil .
This squashes and compresses the bore to a excact size and gives a super smooth finish… I worked in a previous life making hydraulic cylinders and we did the same operation on a capstan… here they used a Herbert 2D capstan!!!!
Sometimes the old way is the best way!
But before we went to the LF HARRIS tour I thought it would be good to take the dogs for a walk on the nearest beach…..Babbacombe and I let my son do the navigation… let me tell you , it’s not always good to follow satnav… we went down a road called “ beach road” it should have been called “ mountain goat road “!!!!!
It was steep and against my better judgment I continued down believing it was one way and thought that the journey back would be via another road.. so I continued to the instructions of Joe… down and down, twisting and down lower till we saw the sea.. we parked up and walked to the groyne.. fantastic veiws and scenery with a great looking hotel and I thought a cuppa in the cafe was a good idea… The guy in the cafe joked about our journey back up the hill saying if we didn’t make it he would have a Americano coffee waiting for me… what !!! I thought … he said get up there before it rains..
all I can say is watch the video as I used all of my 75bhp and hit the rev limiter in 1st gear and smoked the tyres … god now’s how we got up there it was nip and tuck ..

The video doesn’t quite give the entire experience as the smell of burning rubber is not available.. nor is the associated screeching and jolting as the van jumped out of first gear ..and the camera angle doesn’t show the gradient… I won’t be going down there again!
Quite traumatic.
if I was in any doubt about my 25 year Old Ford transit camper mechanical integrity it was exemplified after the harrowing hill climb dodging landrover discovery’s coming down and ruts that trapped and controlled my steering, jumping out of first.., but it did it and we got back for a calming pint in the barrel of beer in Beer.
My god was that neeeded as I thought the local tractor was required to pull us up… all I can say is thank god it was dry😂😂😂
But Jim is still working … making sprockets 😄😄😄

Wednesday morning and we left Durdle Door yesterday in a hurry as it was pouring with rain… my tent which hadn’t seen the light of day for ten years some what suffered from an extended soak … thankfully me and Matt and the dogs were sleeping in the van and only Joe got soaked 😂😂🤣😂
That’s slightly cruel of me..but we left and drove to Sherborne and met Pete Churchill Classic Motorcycles to drop off his BSA A65 bottom end.. we had a long chat and a look at his projects ,a nickel plated framed commando fast back amongst others and in true seager tradition inevitably went to the pub.. the boys had a meal and I handed the keys to Joe and we had a beer or two/three/four.. Pete had stuff to do and so we trundled off to charmouth to buy another tent… a considerable upgrade actually … and ended up here in Beer in enough time to erect the tent and get the van set up.. walked to the pub … for evening meal a quick walk on the beach and a restful night sleep..
Up early to catch the sunrise over Lyme bay… then run the dogs over Beer head… they love an open meadow and thankfully there were no cattle or sheep and especially no deer… a bit too open for munjac😄😄😄😄
No bike pics today… but a gorgeous sunrise and a peaceful view..
I might try my luck off Branscombe beach fishing tonight… as a lad and living at Mistley on the river stour ( At thd end of the river at Harwich Harbour) I fished the quay at Mistley… the main quarry was flounders and eels …. Sadly for one reason or another probable too high estrogen levels the flounders have gone and the eels too are diminished to a point where they are protected … some virus or something.. incredible journey these creatures make from the Sargasso Sea to swim up the rivers to get to fresh water all over Europe … but sadly it’s as thing of the past..later I used to fish most weekend evening tides off Walton , clacton and st oysth beaches .. later Aldeburgh and orford island for Cod and whiting… that too is a thing of the past.. cod stocks are decimated 😡😡

But I came to Beer in 1979 aged 15 with my parents and caught my first mackerel from one off the little self drive boats… me and my dad had a boat at wrabness on the stour and in the summer we would fish there.. but here was different… the deep blue water and the colours of the mackerel shimmering in the water as you brought them up did it for me… fresh and then fried in butter they were and still are one of my favourite meals..
Beer had a small fleet self drive boats and charter boats going out about 4 miles, a cafe and a fresh fish stall, plus deck chairs run by the Aplin family.
Rupert Aplin was the elder and he was present most days either renting out deck chairs or in the cafe or selling fresh fish… as a fishing mad 15 year I took a big interest in the local catch..
There on the slab was the largest plaice I had ever seen… I told Rupert of my biggest flounder at 2lb and asked him to weigh the plaice… I can’t remember exactly where it was 6 lb or 8 lb but to me it was enormous… to which I said that to Rupert…
His reply has stayed with me forever and I often use it to embellish stories in the pub😂😂😂😂
He said in a dry straight face and I quote,
“ boy! I caught a crab so big when it was in the pot ,it stuck its claw out and turned of the gas”
And for a while I believed him such was his conviction and expression..

Precious memories😄😄😄😄

Well day 3 of our road trip and after breakfast and the regulation shower, we set off via Lulworth cove ( great pasty and a cup of coffee) to Corfe Castle on the isle of Purbeck, just up the road from Swanage… famous for bring the original home of Basil Falwty 🤣🤣🤣.
I’ve been before many moons ago but I thought I would take my boys to have a look round …. As an engineer I marvel at constructions and designs of all ages… this castle was blown up after an act of parliament by the great party pooper Oliver Cromwell… it had been a residence of king John, brother of Richard the lionheart… and boy did he live it up there… its position and huge height and scale commanded the surrounding area and as you can see by the photos it was a great vantage point.. but Oliver Cromwell decided to destroy that any any royalist advantage after the civil war with gunpowder… but so was the construction and strength that the gatehouse was tore apart and one side slid 3 foot down the hill but remained upright.. the portcullis slots are witness to that , out of alignment from one side to the other..but never the less the original building must of cost a fortune because of all the carved stone and of the luxury decor inside..and in the most awkward place to build…. No diesel powered help either!
King John knew how to live…a bit of a pattern there😳😳😳😳
After that a trip to sandbanks and a ferry crossing to Poole and on to see an old friend and customer to chew the fat and look at his amazing collection of triumph twins… all around the same years…. The best years late 60s and all built with genuine parts,
Eric likes the American models , TR6C and T120TT…. All in superb show room condition… as much as I should know I don’t as I haven’t seen some of these models before…. Well not as complete bikes… but I love that US spec tanks, folding footrests … such was the quality of Erics builds especially the paint on the tanks was immaculate ( Eric can certainly paint) fantastic colours…. No wonder the bikes sold so well in the states… 3 cups of tea later and we rushed back to durdle door for last order and fish and chips and a pint… early morning and then off to Sherborne.. to deliver a BSA A65 engine

I finally made it away… breath taking veiws over Durdle door as the sun went down Saturday night.. for those who don’t know ,Durdle Door is a natural limestone arch on the Jurassic coast in Dorset … so named because the limestone has preserved so many fossils.. this limestone rock is found in sections running parallel to the coast and is the basis of the purbeck hills… but the sea has eroded this to form the amazing cliffs and spectacular coastal lagoons and coves such as Lulworth…. Another band of rock is about 1 mile out running parallel to the shore right up to Portland where it was mined … hence Portland cement… we can thank the romans for that … it’s that famous line “ what excactly have the romans done for us” straight roads, sanitation , cement and health care”

Still it’s lovely to get away… Friday was a long hard day till 6pm welding this Jaguar head that was badly corroded and has already been welded before but was eaten again around the water ways…
Welding corroded alloy that was previously welded means the corrosion eats into the previous weld like veins and you have to cut out loads to get to a good part… even then you have to “butter-it” to enable to fuse the filler to provide a good enough weld.. no way you can get rid of all the holes… you just have to peen the weld whilst hot to stretch and compress it and HOPE the inevitable holes are either under the surface or not in the sealing ring… either way the tin gasket will need a copper gasket spray to reinforce its sealing.
This had to be done so Jim could pressure check it and start getting it done… he has a list as long as his arm whilst to do whilst I’m not there..
But no visitors please … he won’t be happy !!!😳😳😳

Dorset is home to one more fossil for the next couple of nights … I must say the “Dorset Gold “ went down a treat😂😂😂😂😄😄

Remember the early Norton push rod cover which was cracked and leaking oil…. Well here is the finished repair..

Almost undetectable on the outside around the Norton logo but with a bead on the inside… this was soaked in cellulose thinners and blasted to clean, delicately fettled out the minimum and laser welded.. finally blasted and a quick polish…
But sadly the aluminium although welded and not cracked has tiny porosity over the full length of the dilution zone of the weld is porous … and the dye penetrates thro…but it’s rigid and not flexing but porous😞
It’s disappointing but inevitable.. so I used a rubberised insulating paint called GLYPTAL used in motors for insulation and engines to coat the inside to prevent porosity and create a smooth surface…. Jaguar recommends it … so I gave it a generous self levelling coat and covered it up to cure .. when I get back I will flatten the gasket face on the surface plate with a sheet of wet and dry and it can go home to Scotland..
I’m loading my van now ready to leave tomorrow…
I’m meeting a few people and visiting a few places some maybe very interesting …. We will see…

We don’t always do bike stuff and to be honest its a shame we dont do more car and truck heads etc because it would provide the income and experience to train a young petrol head… multi valve heads are a good way to teach novices and at one time we did around 150 heads a month , facing and pressure checks, seats and shimming plus assembly.. it was good business and a secure job for who I employed but like all good things it came to a end not because of lack of cylinder heads but lack of staff and me deciding to move the business here and concentrate on bikes and alloy casting repairs… but we are set up now better than we were and could resurrect the recon side if we could find a suitable young person who would be committed and reliable..
Then me a Jim could spend more time repairing and manufacturing specialist parts …
Just a thought 😳😳😳

The first head is a Ford focus Peugeot 1.5 diesel which stripped its cam belt and bent a few things … new valves and collets … seats cut and a face and it’s a good un.
The large head is a VW VR6 a shallow angle V6 where the cylinders are nestled inbetween each other and it makes for a compact 6 cylinder able to be transverse in a normal car..
That concept was like the Lancia Fulvia ( 4 cylinder)
Both are not possible to rebore with a portable boring bar like a van Norman 944 but you can using a fixture on a pedestal type borer … the bores run approx 15deg of square with the head face… it has one block and only one head unlike a conventional V6 with two heads…
It’s welding time now… getting a Jaguar head welded around the corroded water ways so Jim can get on with it next week😁😁😁😁

A Dorset owned A65 bottom end just about finished, it needs to have the bearings and the crank fitted and shimmed…
Sadly we cannot finish it till we get some decent conrods… I have brand new steel rods, and could dynamically balance but Ideally I want some late shot peened low mileage genuine BSA rods …. Hint hint if anyone had any?
But needs must and the devil drives so we will see …. I won’t compromise if I cannot find what I want!
I’m trying to get as much stuff done as possible and forgot to photograph the drive side casing that had large bits broke out of the drive casing chain guards…
I could have left them but OCD made me repair them ….. I think since we are restoring this engine that if you remember,had a hideously worn crank and mains bush with the thrust washer that was incredibly worn, shims inbetween the crank and bush… it would be foolish not to make it as good as possible….
I will take this and deliver it when I’m on my road trip and have a beer with Dorsets answer to Ken Dodd as I affectionately call Pete….
A bit of customer integration is always good so I’m also going to drop into see another Beezer man in the Cheddar area too for a pint …,
Now off to work in a couple of hours😁😁😁😁

Busy 4 days a head and then a week off on a camping holiday with my two boys… we are off to Dorset,Devon and Avon… staying at Durdle Door, Beer and cheddar gorge.. Hopefull have to catch up with some people..
This will be the first full week I have not gone into work for 8 years… I will be answering WhatsApp but only in a limited way as it supposed to be a holiday… Jim will be in but he will not be taking calls or seeing customers… that’s not his strong point…. Definitely no “ walk ins” as this can ruin concentration and f**k ups then happen.. minimal emails please and minimal WhatsApp.. normal service will be resumed Monday the 14th.
So effectively the workshop will be closed from Saturday 5th till Sunday 13th… Please be respectful of that and I will move forward as many jobs as possible and supply updates all this week ..
Here is a Triumph 750 crank which had a proper knocked out big end and we stripped the crank and ground it to -0.020”
It’s a long time since I’ve seen a Triumph that was that worn … so we did what is our usual job…. Including resleeving the oil seal journal with a hardened bush.. and we over hauled the rods as one was no longer the right size and round.. new flywheel bolts,sludge tube and b**g …. And yes we did clean the sludge trap…
I will bore the barrels this week and it’s another job that’s been here a while done..
So this week I have been turning work away again.. people asking for blind quotes of mobile phone pictures… not being funny I know what most things look like but it’s how they measure is the key and till I’ve mastered the art of turning a 2 D picture into a 3 D cad drawing … I will stick to having it in my hand and conventional measuring..
Just to add, we blast heads generally to help us assess the work easier and can understand why people don’t want to loose the “patina” but around the guides it is best to blast as the hard carbon on the guide can wreck the hole and often triumphs have quite oversize guides.. this leads to the angle of the guide changing meaning the seat has to be cut deeper.. many triumph heads have very deep seats and although it doesn’t stop it from running , it alters the compression from bore to bore, which effects running also the deeper the seat means the striking angle of the rocker gets steeper putting more side load on the valve increasing wear considerably on the guide and decreasing spring poundage on the seat..

We are busy because I put quality and longevity above quick turnaround.. we can offer quick delivery but not for everyone and I think it’s unfair to push back others who are prepared to wait…
I’m sorry but it’s the same ole story “ there just enough of us”
But how I wish it was different and god knows I’ve tried but the powers to be have made virtually impossible and it too late now to change it
