SS Snuffer,
Tutorial...
I always take glass off first. Gets more weight off quickly and keeps the same profile as the original bow. You have to decide if you are going to keep any of the original writings or not. Next I will trap the back or the belly pending what the glass removal looks like on either side. Plus I always try to keep my original tips for the last 4-8 inches with fades into them...don't want whip ends. If you still need more weight off then I'll try to narrow my limbs thus re-designing the original bow. That's all there is to it. With my grinder, all that takes about 1/2 hour worth of work. Then finish grinder marks by hand and a couple coats of Tru Oil and done. One hour tops unless you are trying to get 20+ pounds off, that's a whole different ball game. I know some people will cringe at this but it works for me and that's all I'm interested in.
As to grinders...
I think most bowyers will be using a spindle sanders. I use my KMG 2X72" belt grinder which I use for my knife grinding. Plus several different attachments...mostly a rotary platen which has a rubber backing and the grinder belt rides on top thus conforming to the shape of the bow. Not a hard surface which will dig into the bow. Both being fairly expensive to just take weight off a bow or two...tippit
