Wow, way cool
Are you grinding dry?
With stainless being so "sticky" I can imagine your concern with loading up the wheel and keeping the thickness uniform, quite a task.
Great job.
Oh, one point of order
Silver cloth tape used to be called duct tape but it no longer is as code duct tape is now a metal tape with a sticky surface. Silver cloth tape is called "duck tape" or just cloth tape by some companies wanting to avoid code complaints.
:-))
All the best and I hope the wonderful #97 is alive and well. I've read that thread several times. Real inspiration.

No, I am using coolant.

You're correct, it is a cloth tape.

Both services look great and I would have no problems using either.

I have Godffrey roters on two of my bikes with twin disc set up and I like them very much. I was just curious as to opinions on thinning the 7mm Honda rotors to 4mm. Personally, I don't have an issue with it as others have stated. Both of my bikes are on Godffrey's gallery for the product and I do believe they are Blanchard ground but I can't confirm that. I don't have a lot of mileage on either of them after conversion but I have no reason to think there will be a problem.

I really was just trying to spur on conversation about thinning vs not thinning.

Here are my Godffrey disks:






Those discs look awesome imho. Love the dual disc setup!
