Refacing rocker arms - how is this done?

I am trying to collect tools to rebuild old engines. Several of the engines I have will need - 1930-55 tractors will need this.

I understand that valve refacers (grinders) can do this, but what does the tooling look like?

What other precautions should I observe?

thanks

kevin

Thanks for the reply. I found the tooling to grind the rockers - I suspected that is what it was.

However, this mount is for a different model grinder (different color) & I am not sure how or if it can be mounted properly. Anyone have a photo of their's installed?

thanks

kevin

Both my Sioux machines have the rocker-grinder attachment.

I have one with my old Black and Decker valve refacer machine. This machine has 2 stones. One you use for the valve face and on the other end of the machine there is one you can do the ends of the valve stems then pull out the vee block attch. for the stems and insert the rocker attch. which is an arm with an adjustable slide the has a pin with 2 cones that thread into each other. You stick these cones on each side of the rocker arm where the shaft goes,thread them together which holds them tight and centers them,then this sets over a pin and then you just start grinding. Start at one side and as you go tilt the lever out and rock the rocker so it matches the curve of the face. Kinda hard to write it all down. Hope it made some sense.
