View Full Version : Sears 10" Radial Arm Saw to 12"

I am trying to convert my 10" Sears Radial Arm Saw to carry a 12" blade. The 10" blade has a 5/8" arbor and the 12" blade requires a 1" arbor. Does anyone know where I can find an arbor adapter so I can use a 12" blade ???

You probably won't get much help as the changes could be dangerous. Everything on a 12" saw is beefier to handle the added stress.

It's not going to work. For one thing, the blade guard won't fit the larger blade.

I'm not sure how much it really matters with wood, but the RPM of a 12" blade should be a bit slower than a 10" blade as well as what the above have mentioned.

Most 12" blades are rated over 4500 rpm so from that aspect it would be ok...
But trying this is probably dangerously wrong. :eek:
If the arbor can stand the stress (unlikely, that's why 12" blades have a 1" arbor hole in the first place) the bearings most likely won't hold up. They're rather small on a radial saw like that.
They sacrifice much to get: a little extra cut depth out of a 10" blade, a low price and low weight.
Compare the construction of a 12" saw to your 10" Craftsman and you might notice the extra mass on the larger saw.
Without any guard (are you thinking of adding a guard?) and bearings likely to fail, I wouldn't be in the same room...
