I have been wanting to post this a long time ago, but didn’t get around to it.

I installed the PALS kit on my 113.29943 table saw sometime ago and using the left miter slot and the A-Line-it kit with a dial indicator, performed the blade alignment, but I am not able to reduce the error between the front and the back of the blade below 0.004”. Looking from the front (the operator end), the back trunion needs to be moved further to the right by at least 0.002” but it is at its end stop and can’t be moved any further.

Should I take the saw apart, re-align the front and back trunions so that they are in the middle and then start the alignment process from there? I am cringing just at the thought of doing this. Is there anything else that can be done?

Thanks!

Maybe it’s just me, and maybe I’m wrong, but I would be fine with a 4 one thousandths of an inch margin of error.

If you want to tune the 0.004” out, then yes you will need to move the front trunion. You might not have to disassemble the saw to do this. You should be able to loosen the bolts from below.

Well… Burgels brought up a good question… should I be concerned with such an error? The reason I was trying to achieve 0.002” or less is because of what I have read on various blogs/forums and seen on wood working videos that it is desirable to have the error of less that 0.002”. Please correct me if I am wrong.

Also, if I opt to adjust the front trunion, can someone please guide me through it? I have read at various places that loosening all trunion bolts at the same time spells disaster.

I have read at various places that loosening all trunion bolts at the same time spells disaster.

IMHO, only kinda sorta. the “danger” with loosening all 6 trunion mounting bolts too much at the same time is that the entire undercarriage can shift too far to one side so that beveling the blade will result in contact with the OEM insert. and i suppose that loosening all 6 bolts to the point where the undercarriage falls away from the underside of the top could also make for some difficulty. short of those two situations, it should not be all that difficult to align.

i have two similar saws and i use a cheap ($5 on clearance @ rockler) digital dial gauge (any dial gauge will do) and my miter gauge. while it’s very possible to successfully align these saws with much simpler “tools”, i like a dial gauge as it helps determine which part of the blade should be adjusted which way. here’s one of my 113 series saws:

infeed :

outfeed:

it’s probably not necessary to have the alignment better than a .002” in to out feed difference, particularly if the difference toes the fence out slightly at the outfeed side of the blade away from the blade and the fence is not used to the left of the blade (where the fence would be toed INTO the blade). my feeling has always been that, since it isn’t really that difficult to achieve dead on alignment, it cant hurt to do so. with a little patience and careful technique, any saw can achieve similar results.

here’s a couple of alignment instructions to get you going:

http://woodgears.ca/delta_saw/alignment.html

http://www.newwoodworker.com/basic/tsalign.html

the back trunion needs to be moved further to the right by at least 0.002” but it is at its end stop and can’t be moved any further.

also, why not move the front trunion to the left? whatever the difference, only 1/2 of it needs to be addressed at either end. it’s a bit of an iterative process. just align both the blade and the fence to the same miter slot. hope this helps.
