Poly Vee Pulley

Post by dazz » Wed 08 Jul , 2015 1:33 am

Hello

Another small project finished.
This is a poly-Vee pulley for another VFD lathe conversion and is made of mild steel.

This is the forth pulley I have made so I am refining my technique with each one.

I rigged up a pretend DRO to accurately space each groove.
Each groove was cut by turning each side of the Vee (and not using a form tool).
The Vees are honed to ensure a smooth finish.

The dark colour of the steel is the result of pickling in phosphoric acid for a couple of days.
I have found this to be an effective rust inhibitor.

The Budget DRO. Very simple but accurate.

Turned from solid 75mm bar. It is very important to get the holes in the right place.
