As long as you have the clearance ( trunnion,,throat plate,etc.) you could but will likely not be able to raise it to full height. Any particuler reason you want to do that ? There will be no added advantage.

Even if you can manage to mount it, it would be a bad idea. You’d be unable to raise the blade all the way up, of course, but even lowered there’s a good chance that it would contact other table saw internals. It would very likely hit the splitter/riving knife. It might also hit some other parts. This would obviously be bad, but it would be even worse if almost or barely touched something and then made contact fully when you turned the saw on. It would probably be unacceptably wobbly, too, as the arbor wouldn’t provide the support the blade is designed for.

So basically, don’t try it. It’s not a good idea.

If the saw could safely run a 12” blade it would have been sold as a 12” saw. I would definately not try it.

What you can phyically do and what you should do might be two different things. What’s the incentive to take on the added risk? I definitely would not do it.

I’m going to say NO !!! Unless, of course, you like sparks and shrapnel flying around (and probably THROUGH) your head. Seriously, it’s misusing tools, trying to get them to do what they weren’t designed to do, in a way that is physically impossible that gets people hurt; even killed. Don’t even think about it. If you are having a problem making a cut, state it here and about 5,000 LJs will leap (or stagger) to your aid. Please don’t do anything dangerous. I get nauseous at the sound of a bloody story.

Don’t do it. If you need a 12” saw, buy one. There are plenty of
older, used 12” saws out there. Sears even made some.

I would not categorize such a move to be one of those “calculated risks” that we sometimes take as woodworkers, such as not wearing full eye protection when wearing a magnifying set to do a router inlay.

This could have a very bad outcome.

Please do not attempt this!

My first thought was NO…

If you’re curious to see if a 12” blade would fit in the saw, cut a 12” out of 1/8” ply on BS or Router, cut the hole, and see if it fits.

The motor is probably NOT designed to handle it…

My last thought is NO…

I dont know if you can or can’t. I know if you can i can’t think of any benefit, if you can’t i hate to think of how bad the catastrophic failure would be! Scares me and I’m fearless!!!!!!

even if it worked (doubtful due to all the needed clearances top, bottom and middle of the blade and I won’t even get into the engineering issues on the impact on the saw guts), check out the prices of replacing a 12” blade vs. a 10” blade…that in itself should give you the answer. After recently replacing an 80 tooth 12” on my miter saw, I’m in the market for a 10” model for anything that doesn’t require the bigger one.

Generally speaking, you can put smaller blades on saws. Take an 8in dado on a 10in saw, fine results. NOT bigger blades. The extra torque alone would probably strip something and would bog down every time it touched wood.
DON”T DO IT. Hope this helps.

In addition to all the other negatives pointed out in the previous posts it would take a higher horsepower motor to power the larger blade or a smaller diameter pulley on the motor to get the proper torque to the blade. This would result in the blade not turning at the proper RPM. All together a bad idea.

No No NO NO NO NO NO and NO.
Bad idea all around.
Sounds like someone has a 12” CMS blade and is thinking of using it in a 10” TS. Possibly one of those with a 1” arbor!
Really really bad idea.
And BTW, wouldn’t the teeth be running at a slower RPM being further from the center.
How’s that work anyway?
