From Tom's post I learned that this gaging method is just like that for Gleason No. 3 machines (which I have experience with).

One thing shown in Tom's third photo is the proof block in the bottom of the box for setting and checking gages for accuracy. Each proof block will have a serial number that matches to the machine (at least for the no. 3 machines). These proof blocks were set and delivered with each machine when it came from Gleason. Once machines move around from shop to shop, you would be lucky to get the proof block that came with your machine, much less if you get one with your machine.

What you are trying to do is set the cutter point on the imaginary root cone of the machine. Since you are gaging a cutter point in reference to machined surfaces on each "clacker" box, these surface locations likely vary slightly for each machine - that's why each gage set must match each machine.

No. 3 gages have dial indicators on each gage, and you set each dial to "0" when placed on the proof block.

Once you get a gage set, and if it doesn't have dials to offset each proof setting to match your machine, then you will want to adjust the proof block for your machine, but I don't know how you do that.

Maybe someone has figured out how to make adjustments and would like to share, since being able to set the cutters makes setting up the machine much easier than "cut and try".
