Re: DRO on a Grizzly G0759 question

On my Grizzly, G0720R, I put the Z axis scale on the head movement. If I need precise measurement of the quill, then I use a dial indicator.

Re: Mikado Logger 2-8-2 AutoCAD drawings

Re: Induction furnace ratings

Re: Proof testing cable clamps

We use a different type of stanchion where the large round ring, the one with the furnace leads, is the first bearing point, an...

Re: Proof testing cable clamps

Chains get very hot around induction furnaces. We used fairly fast cable hoists to tilt the furnaces.
