Carpentry and Woodworking - table saw

I was wondering would it be safe to use a 12" blade on the table saw rather than the 10" or would it even fit.
Thanks

I doubt that it would fit besides a table saw can be too dangerous to modify it to do something it wasn't built for.

A larger blade will reduce the power and may even burn out the motor.

Be thankful that you have a ten-inch saw. My table saw uses NINE inch blades and you just try to find a nine inch blade. I did measure once to see if I could fit a ten inch blade and it looked like it would fit so I bought a ten from Harbor Freight (less than $10 on sale, maybe less than $5). When I tried to put it on I found out that it wouldn't fit, it was maybe an eighth of an inch too big and would hit on a casting boss of the arbor assembly.

another thing too, if there isn't sufficient clearance for the blade, a splinter or maybe a little too much saw dust would bind up the blade :eek:

I don't think I've ever seen a 9" blade - I bet you stock up on them when you find them ;)

It is an old Craftsman (Sears) bench saw, at least fifty years old. I do have several blades but I need to find a local sharpening shop. Mostly what I use are 7-1/2 inch blades.

What I REALLY need to do is tear the thing apart, clean everything up and re-align the blade. The darn thing isn't parallel to the miter gauge slots and THAT is really frustrating when trying to make square cuts. :wall:

Just for the heck of it I looked in some of my saw blade catalogs... there are a few 9" blades made by SystiMatic, a few by Tenryu, and quite a few in my Everlast saw catalog.

Is the table and body made of cast iron, Furd? With a motor out front, pulley and belt driven?

Table is cast iron and the body is heavy sheet metal. Belt driven with the motor on the back end if you consider the front as being the place the operator stands when pushing the material through the saw.

I inherited the saw from my daddy who bought it from a neighbor when I was about nine years old so I know it is at least fifty years old. I did have to replace the motor several years ago.

I have a 9 in. Craftsman radial arm saw purchased new in 1964. I have found blades at Sears and the big box, but I am not a heavy user anymore so do not buy many blades.

Yeah I hear ya. Used to be a heavy user too. But I had to cut back. It consumed me. My life was reduced to joylessly going through the day, just to get to the next birdhouse. It tried to hide it. But when I would come in from the garage my wife would just give me that look and I knew... I knew ...that she could smell the sawdust on me. :rolleyes:

The Arbor will be too big, they do this for a reason, so you can't do stupid things like put a 12" blade on a 10" saw.

Do not use anything but a 10" blade on a 10" saw.

My 6-1/2 inch Skilsaw has the same 5/8 inch hole as does my 9 inch table saw. I have used every size of blade from 9 inch down to 6-1/2 inch on my table saw with no problem. Where there may be a problem is the "tip speed" of the bigger blade. The bigger the blade the slower it needs to turn to reach a desired tip speed. This is why the blade speed on a 9 inch saw may be 3500 rpm (an example only) while the speed of a 4-1/2 inch portable saw may be as high as 7000 rpm. I think the safe speed for any circular saw blade is somewhere around 25% higher than the particular saw speed so while it is possible that a 12 inch blade on a saw rated for 10 inch blades could be approaching the maximum speed allowed for the blade I don't think it would be exceeded. Therefore, if a 12 inch blade would physically fit a 10 inch saw it would probably (but not always) be safe to use.

I think that is what he was getting at when he mentioned the arbor... that it won't physically fit. With very few exceptions, 12" blades and up have a 1" arbor. :)

Would it be ok to use a 7 1/4" blade inplace of a 10 " blade on a table saw.also a 12" inplace of a 10" blade.

You recently asked this question and got some pretty good answers.
Simply put, you can use the 7 14" on a 10" saw but not a 12" on a 10" saw.
