Hi all,

I have an old Craftsman Table saw (model number 113.29930) that I’m finally getting around to tuning up. Its this one parts schematic

Right now, the blade is not aligned with the miter slides. I often see threads on here about tapping the trunnion to pivot it around one of the four bolts to align the blade. But, two things make me think this won’t work on this saw. (1) this saw has two trunions so tapping it will only move one trunion in a best case scenario. And (2) the trunions do not have slotted or slide holes. Rather one perfectly round hole per bolt (two bolts per trunion) and the holes are pretty close to the bolt diameter.

So my questions to you are: (1) Can you align this saw in this fashion? (2) Could you align the blade to the miter slots by adding shims between where the motor mounts to the bracket? There are four bolts that hold the motor to he bracket and if the blade were in a 90-degree position, you could align the blade this way. I’m just not sure how this would affect the blade and cuts if you were to tilt the blade away from 90-degrees. Any thoughts on this?

Thanks a million and have a great and safe New Years!!!

Robinhood, Here is a link to a manual for a Craftsman saw similar to yours (thanks VintageMachinery.org). The trunnions are closer together than a contractor saw but adjusting should be similar. The location of the trunnions (both in the front of the saw) in relation to the blade (cantilevered behind) means a tiny adjustment of the trunions will move the blade a lot. PALS might help if you need them-check with them to make sure they will fit your saw. I think motorized saws were addressed on Ed Bennett’s TableSawAlignment.com -You need to register to get on but I think it is worth it. I would not shim the motor mounts on that saw. Technically your saw is a motorized or direct drive saw not a contractor saw. Good luck. -Jack

Thanks IRReverentJack!!!!! I have never had the instruciton manual on this saw and do not know saws well enough to say “hey, model a is just about like model b”. You must know Craftsman tools, inside and out!!

I think the only difference between my saw and the one you provided a link to is the side table panels. Mine are solid aluminum and I think the saw you provided a manual to has webbed steel.

I’m going to give this a shot tomorrow. Thanks again!!

Hi all…I’m not sure if this thread has been closed or not, but here goes. I too have an older craftsman TS. MODEL NO.
113.241591 this is a Flex-Drive. Maybe some of the old timers might remember this one. Anyway, my problem is this. Recently, while I was trying to get a perfectly straight rip cut, I saw that the fence had to basically be tapped with a light weight hammer at the end to get it in line w/blade. NOT a Good thing!...also, I hadn’t noticed this other problem b4, but when I removed my ‘0’clearance insert, and looked at blade, all looked good, until I just tried to move the blade a little sideways. Shock!!...the was a minor wobble at the arbor. The blade was securely tightened, (the nut was tight). the nut holding blade, not the one checking for problems. ha ha. But, seriously, I am getting very frustrated with this old saw. Also, when I try to do a bevel on this…...FORGET IT!!!...this is where the saw becomes a living thing!!...when I try to tilt it, everything becomes extremely loose. It makes me very apprehensive. So, I do not do any bevel cuts at all. Sadly, when a major benefit of TS’s allow them to do all kinds of degree cuts.

Well I think that’s about it.

So, please any and all help would be welcomed.

BTW, I would love to purchase a new saw, either Hybrid, or cabinet. But, budget does not allow for this at this time.

thanks in advance…:D

Happy cutting, and make some sawdust!!

Have your say...
