New (old) machine in the house. Picked up a Hardinge Turret Lathe. It's been sitting for a good spell. Got her cleaned and running. She'll need some more TLC as the variable RPM system is not working.

The collets that came with the machine needed a deep clean to function. Years of oil and grime made them almost useless. Not anymore! We have inhouse REM Surface Engineering machines. After a few hours the collets are like new!

Soon we'll be using this old girl for some light production. Stay Tuned!

Hello all - it's been a Long time since our last post however we have a Ton going on. Stay tuned for big updates!!!!

Bulletproof reliability has become the norm in the automotive world. While vehicles built in the ‘60s were only expected to last to that magical 100,000-mile marker, it’s not uncommon for the most basic of modern-day beaters to surpass a quarter of a million miles. Enhancements in manufacturing ...

It's been some time since our last post however we're as busy running Cryo/Rem Polishing as ever.

The next service we're offering is Cerakoting - we just completed our first job. These are a set of 1962 Jaguar Exhaust Manifolds we Coated Glacier Black. They turned out great for our first run.

Stay tuned for more exciting updates coming soon.

It's been a while since my last post however we've been extremely busy. We've probably Nitro-300 Xtreme'd 50+ Tremec 5 & 6 speeds thanks to American Powertrain this year.

This update is to show a brand new Yukon Gear & Axle Ring & Pinion for a GM 8.5" rear-end, my personal project.

As you can see - straight out of the box the ring & pinion are coal black and rough as a country road. Why is that a concern? Because all that soot, shavings and garbage will cause friction and wear immediately - now all that crap will contaminate the fluid and flow to the bearings - not a good idea for a build.

So first we Cryo treated the gear set for added toughness, but more importantly we then Micro Polished the set which not only removed the grit and grime, but polished away the microscopic Peaks & Valleys for a smooth - less friction surface. Now once installed the rear-end will require NO Break-in period. It's a no-brainer!!!
