handles blades much bigger than my makita 5" bench one which i hardly use now with TC blades.It can handle 9 1/4 " blades. Spose there are stones for them (TC): I just haven't looked.THe makita handles a little set but i never needed to try ones with heaps of set for really sappy woods like pinus elliotii.
With that machine one would have to know the diameter & exact number of teeth And as Frank mentions the set?.

I worked as a tool grinder for 17 years and I ran very similar machines. Mine were perhaps a bit more modern. The blade looks to me to be hollow ground on the sides (tapered) thus not needing set. It more than likely is used for cutting copper or aluminum. Just my opinion.

Nothing like old thumper motors, machines and Lederhosen...and finally we now know how they got that limb trimmer down!! I knew there was a use for kids...Hooray!

That is where many in the been counting department have it wrong. especially those who cannot differentiate between bottom dollar cost versus longevity of service.
they simply believe that change out times remain the same for top of the line or bottom of the line where they fail is in not accounting for the frequency of having to change out the cheap stuff. or the reduced quality of product at the near end of life blades.
And no most times it is not worth re sharpening the cheap blades. the hardness is not there the coatings once worn off leave the blades to create higher friction and even warpege.
Never try to tell me it can't be done
When I have to paint I use KBS products

As I stated previously I ground tools for 17 years and in the first 4 years or so we were using what was called Semi-high speed steel blades. Thes blades did have a set put on them. How we did it was set the teeth before grinding giving a bit more than needed and for copper and aluminum we just ground them enough to clean them up straight across the top. On the blades that were needed to cross-cut wood the machine was set for half the number of teeth thus grinding every other tooth, and the wheel was either dropped or raised a certain amount to give the alternate bevel grind. After one side was done the blade would be indexed to start on a tooth of the other side. Most of the blades we ground were 12 to 14 inches in diameter.
