Hi Dave,
I have used buttons when profiling bosses on a part but not to the extent of having them spin when touched. I generally just blue them up and when I see the color change I move to the next X-Y spot.
Having an AutoCAD program allows me to make a step-over chart for most of my bosses, that way I can just crank to the numbers and not worry about getting my head down close to the work to see the button.
When I served my apprenticeship all of the 'old' journeymen on the mills had their own bible for stepping off radii. At that time there were no calculators so all the sine/cosine math had to be done by multiplication. They would have the desired radius using a standard diameter cutter per page and depending on their math skills the book might have 20-30 entries. Naturally you only need the calculations done for 90 degrees and then you start over.
Great whittling work.

Thanks George!   I'll try that next time.  The button method works well for small diameters...but the big ones are a bit nerve racking.

I'll put a spreadsheet together to do the table...though I put a BT-2 DRO box upgrade on my Christmas list...it' does bolt circles....

Interesting read, Dave.  On first look, I thought sure you were using CNC.  So I went back and looked over the whole thread.  Good stuff!

OK....vacation is a wonderful thing!....got some time at the lathe and bench, and although I still have some filing and cleaning to do...the gear case is in place and looks like it will work well!







So I'll finish the clean up, and the alignment arbors for all the gears, make up some studs, and finish the gear case machine work on the mill.

Now the question....do I try out my new die head?....or just use a button die for the studs......hmmm

Nice work Dave and I have learned on this so far. Glad to see you back at it again. It will be interesting to see how much this week will give you buddy. Keep pluging at it.
