Hi folks,
im in process of playing around with mounting an 8" 3 jaw Chuck to my rotary table. My plain back chuck needs an intermediary plate to attach to my table slots. I got hold of a Somewhat oversized 10" diameter disk of gray cast iron, assuming it would be a good choice for this.
the disk is sawn off but roughly turned. I would like to turn it to have both sides as parallel as I can get it. I haven't tried anything just like this before but have a picture in my head of what I want to do but am a little spooked to start it since I don't want to mess it up.
i made some stops for my 12" 4 jaw Chuck kinda using the idea I see Tom Lipton do. I'm no tool maker and the stops likely took me as long as it will to do the rest of this project. They certainly didn't come out as nice as his but I think they will serve me.
I wasn't sure if I should average the thickness before facing the first side? At this point, I just arbitrarily set the disk onto the stops which I set to equal length. Once I dialed in the O.D. The outside face to be turned is about 0.060" total indicated runout. I'm thinking I should true the face, then the OD and flip it around? On the flip, I may skim off the stops to try to achieve better parallelism.
Any hints, tips, tricks would be appreciated! I'm hoping to get this pretty flat and with in a thou or better? On thickness...
