0.35 blade?


 

Hello all.? I ordered blades for my Jet 4x6 on sawblade.com and the selector showed .25 & .35 thickness compatibility.? I should looked at the manual first as it shows it is specified for only .25.? I would like the use of a thicker blade from time to time if possible, so any thoughts on how to modify it to get it to work?? I would think just a slight smaller set of roller bearings is all that is needed.? Thanks for your help and all the great info here!?

Well….a .035 blade will work, but is not ideal on a small saw.

Thicker blade does not bend as easily. The worst is the twist required to turn 90 degrees from the blade guide to the drive wheel. It’s a short distance on a 4” x 6”. Same problem exists from the idler to the upper blade guide, but not as dramatic.

Just the diameter of the drive & idlers is also a problem.

So….yeah….assuming there is enough adjustment in the blade guide adjustment to fit the .035” blade, (I don’t know that there is…) ?it will work, but it will be tougher on ALL the bearings. Drive & idler wheels, and the guides.

May also be hard to tension, and the blade may tend to walk off the drive wheel, because of the increased force it has from the twist, compared to a .025” blade.

?

Also, switching back & forth, will require adjusting every time you do.

I use Irwin 10-14 blades, 99.9% of the time. The thickness is consistent, and I don’t have to adjust the blade guide bearings for a blade change.

A .001” or more on the thickness, will affect the tracking of the cut, and I know this from using different blades from different manufacturers. .025” is nominal.

?

And, I would guess it will cut slower. Wider kerf….more to cut.

Also a bit more material waste. Not a biggie by any means….but exists.

I wouldn’t suggest it. You may get away with the thicker blade but it will likely fatigue much faster

Bill's right on the money.
Slower to cut by about 25-30% (removing .035/.025X material), more tension to get it to cut properly, more load on bearings, crack more readily (doesn't like the smaller radius), though that's all pretty small beer.
Biggest drawback I'd say is having to reset the blade-to-guideroller gap each time to get it to cut square vertically down.??
I can't think where a wider kerf will be that valuable, better to have different TPI blade in .025, than an extra in .035
If you really think its worth it, I certainly wouldn't get it in Bimetal, Flexback would do as well in most metals and be more flexible as well, reducing those loads etc? - jv
