HOW-TO Shim A Toolbit

The stock turret-style toolpost is real basic. it works, but you'll most likely have to shim the bit. In this case, a quick-change tool post (QCTP) would be highly advised. It saves time and is easy to adjust.

this is a 1/2" bit
this is the resulting face cut. note the nobby thing in the center. the bit is too low.

with a QCTP, you can adjust the screw to the correct height.

in the meantime you can just shim it.

this is a 16 gauge piece of mild steel.

the size is for demonstration purposes.

please DO NOT have an extended shim like what is shown. this is dangerous as it may get caught in the workpiece or worse, in the chuck!

here's the resulting cut of the same piece after being shimmed.
we're still a few thousandths off. you can use shim stock like what you see here to finitely adjust it.

it's better just to find the correct height for your setup and make an accurate shim out of mild steel.

here's the packaging. you can get this stuff in different thicknesses.

Looking for mini-mill help and how-tos? How about lathe help and how-tos?

We're prototyping a benchtop CNC vertical mill using the DigiSpeed-XL interface card for Mach, Dart Controls and KB Electronics KBIC/KBMM 90VDC motor controllers, 1.5HP treadmill motor from Surplus Center and a R8-spindle head from the X2 mini-mill - not to mention Gecko servo drives and an entirely closed-loop system. Come take a look!
