12" blade on a 10" TS?

[Chris Padilla]

Anyone ever do this?

Using my crosscut sled is taking away valuable height I need for a particular cut so I got to staring at my compound miter box's 12" blade and wondering....

I have a DeWalt CMS and it has a 5/8" arbor but comes with a nice spacer/washing/bushing to take 1" arbor blades.

After removing some splitter stuff near the back of the throat opening on my TS, I appear to have decent clearance and it sure looks like this could work like a charm!

Since I'm using a crosscut sled, I've decide to leave off the ZCI since I'd have to make a new one special for this large blade.

Chris, I have a 1958 unisaw and I was cutting segments for a bowl (wood standing up) and the 10" blade wouldnt go through so I put a 12" blade on and it worked fine except for 2 small problems 1. blade wont retract all the way down below table top 2. I have a 5 horse motor and blade will wobble for about 1 second from start up since then I use blade stabilizers

Chris,
You know full well who as done this:

From him I guess it worked on his saw. This may be saw specific. huh?

I have a 5 year old Shop Fox/Grizzly 10" 3HP cabinet saw. Yes,a 12" blade works fine for me in that saw.
It won't retract below the table,but no wobbling as David mentioned. The ZCI on mine nearly gets cut thru to the back edge at full 4" blade height. This has not been a problem but I may reinforce that area with aluminum.

Of course spin the blade by hand (saw unplugged) at all possible heights and angles to be SURE you have clearance.

Oh man, now I can just see all you guys with 12" saws looking to see if a 14" will fit!

[Joe Chritz]

As a matter of practice it isn't a good idea since the saw isn't designed for that size blade. However, for using it with a crosscut sled it could work just fine as long as it clears everywhere.

One of the biggest problems I can see is horsepower. 12" tablesaws are pretty industrial but as long as you account for clearance and don't overload the motor it should work great.

I put a 14" on my 12" once for some weird situation, and it was no problem, and as others have mentioned it stood above the table. Now if I could just fit 16" blades in my 14" RAS.....

[Steve Rozmiarek]

My Felder manual is about half full of warnings about overspeeding cutters and blades. Never paid that much attention to rated rpms before I could set them with the turn of a knob, but deserves a look at least. Bigger the blade, slower it can turn.

Memories fade fast, Dewey! ;)

While I'm not ripping anything, I do have to crosscut a piece from the Tansu I am building. This panel I'm crosscutting is two laminated pieces of 5/8" MDF (17" x 48"). No biggie with a 10" blade but then I wrapped the MDF sandwich's two long edges with 3" "tall" walnut and now I need to cut it to proper length (47 1/2") so hence the need for something taller than what my 10" blade can handle.

I was thinking to use my bandsaw but it would take more setup and I'm not confident I'd get a very clean cut. My 96 tooth, 12" CMS blade looks like the perfect blade to get me a nice clean trim on this panel. :)

BTW, I'm doing this on my 1023Z Grizzly TS. I did end up putting a spacer/washer over the arbor in order to shim out the 12" blade just a hair so it wouldn't hit the cast iron protuberance that holds the blade guard.

[Frank Drew]

Chris,

In principle, there's nothing wrong with mounting a larger blade if it fits, doesn't hit anything it shouldn't, etc.

My only concern is if the CMS blade/tooth geometry is significantly different, in a way that matters, from what works on a table saw, in terms of rake angle and so on. No opinion, just wondering.

[Chris Padilla]

Frank,

Excellent point but I only need to make two crosscuts and so I'm hoping things work out okay. I'd hate to fork it out for 12" TS crosscutting blade just for these cuts....

[Chip Lindley]

As Yogi Berra (almost) once said, " If Nothing Touches, Nothing Touches!" Go for it! (With a very qualified: "proceed at your own risk!")

[Chris Padilla]

"It's like déjà vu all over again...."

[Mike Goetzke]

Chris - I would just look at the blade (or look at the mfg. spec.) and see if the blade is rated for your saw RPM (the tip speed goes up linearly but stresses go up as the square of the speed). Other than that for an occasional use it should be fine.

Mike

[Charlie Plesums]

I, too, would worry about the tip speed (which gets a lot faster as the diameter increases), also related to max RPM.

My 12 inch saw takes 10 or 12 inch blades, but the 14 inch version of my saw has three different blade speeds, for 10, 12, and 14 inch blades.

[Chris Padilla]

Well, I made two crosscuts last night with the 12" blade and all went very very well.

There was no wobble to the spin and it crosscut very cleanly and so I'm thrilled with the results. I will have to file this away for the future!!

[Chris Padilla]

Some shots of using my miter box 12" blade on my 10" table saw and the results of the crosscut. That is an Incra M5k sled I am using.

This panel is part of the Tansu (http://www.sawmillcreek.org/showthread.php?t=92396) I am building.

That walnut trim is about 2 7/8" high or wide and the 10" blade with the 1/2"+ sled wasn't cutting it for me (so to speak).
