I was auctioning yesterday and came home with a big darra James cabinet saw, a 12 inch craftsman band saw and a radial arm saw. It is in nice shape but needs a bit of fence work. I have my plan to get it back in line. I have been unable to locate a model number. It came with a 10" blade but looks like a 12 will easily fit. I read of a 3\4" arbor on them. Does anyone know of a 1" to 3\4" arbor bushing for a 12" blade? Can a 10 inch blade be safely drilled from5/8 to 3\4"?

I tried kinda unsuccessfully drilling out a 5½" blade. :-\
My thoughts are that you might be more successful reaming out the hole rather than drilling.
Not a bad idea! That may be more successful

I never even considered having them drill one. I can get stuck on box store availability some times.
You won't get a round hole with a drill bit. Better have it bored.
Would a step drill or unibit work?
Don't know what a uni bit is but a drill just doesn't make a truly round hole. Looks good till you really give it a close look. Sometimes looks sorta triangular shaped if you really look it over. I would hope for a closer tolerance for a blade running on an arbor. Just my opinion.
Here's a site with some manuals published for that company:

Yesterday I reamed out a 10" blade and put it to work. I ended up swapping wings from one side to the other for a wider cut. With a bit of reworking on the fence this will be a huge upgrade. The far end of the fence was missing some parts and had some homebrew repair that I don't care for so I am redoing it. Next I want to add more to the table to have at least 48 inches of cutting surface.
Blades are pretty hard metal. Boring with a carbide cutter would work. I don't think a unibit will hold up. Glad you scored big at the auction.
I also have a 12" table saw with a 3/4" arbor. I usually use 10" blades that have been cut from 5/8" hole to 3/4". The best way is to use a milling machine with a rotary table. Perfectly round and perfectly centered. Send yours to me and I'll mill em and send em back. You could also use shaper bushings to bush a 1" blade down to 3/4".There might even be something that'll work in that molding head set I sent you.
Never mind. There's nothing that goes up to 1" in those sets.
