Topic tags/keywords: table saw arbor nut

After reading the posts about the arbor nut being stuck, I finally got my bade off my table saw. But now the arbor wrench is jammed so tight on there I can’t get it off. Any suggestions???? I’ve tried WD40 and a hammer.

heat it with a bottle torch. (the wrench – not the nut).
if your hammer method is not working ~ you need a bigger hammer !!!

WD-40 is not a penetrant – and will not work on two pieces of steel that is only forced together.
heat and coaxing it apart with force is one way.
if you have an identical wrench, sacrifice the stuck wrench and cut it off
with the angle grinder. (the wrench – not the nut).
a piece of pipe, socket, or something that the nut will fit in would provide equal support
around the nut while tapping it out with a hammer.

Where is it stuck… on the arbor? If so, stick the blade and nut back on there so you can apply force in the opposite direction to back it off and break it loose. In the future, just use a wrench on the nut, not the arbor (just use a 2×4).

I’m assuming that it is one of those flat stamped steel wrenches. If so, it is likely that it is a much softer steel than the arbor nut and since it is stuck that tight, it is probably chewed up and deformed anyway. I suggest that you cut it off and buy a new one. Hopefully your arbor nut is OK.

If brute force isn’t working, it’s because you aren’t using enough.

well – since Lindz, the O/P hasn’t checked back in, he has either fixed
the issue or broke it beyond repair – who knows. . . . . . .

Thanks all for your help! Sorry it took so long to respond. We ended up moving, and I sold the saw for an upgrade. Definitely hoping I don’t have this problem again, but if I do, there will plenty of options. At the time I did not have a torch or a grinder.

Brad has the winning answer, even though OP didn’t say whether he solved his problem before unloading his saw. .

I have been using some piece of wood lying around to use as my second wrench for at least 40 years. Never has it been an issue to remove a blade. Also when tightening, I lay the outside nut wrench in the throat with the nut snug, and slightly rotate the blade towards me until it’s tight. Have never gotten a blade stuck, and have never had one slip until I just recently got one of those thin kerf Diablo blades. They paint it with slick paint that keeps gunk from building, but it doesn’t allow for the blade to get tight by operator. It tightens itself…....... Jerry (in Tucson)

For saws with flats on the arbor I would say that one wrench there and another on the arbor nut itself is the best way. Works like a charm on my Sawstop.

At the risk of opening a can of worms debate, I recall reading several places that you should not jam a chunk of wood between the teeth of a carbide tipped blade and the table top to keep it from spinning when changing a blade. This was discussed in an earlier thread on the forum:

http://lumberjocks.com/topics/47911

One comment stated: ”+1 on KS’s leather glove suggestion. that’s what i do. also, forrest advises against using wood to chock the blade teeth:

http://www.forrestblades.com/Forrest_Saw_Blade_Instructions.pdf

see “installing blade on saw arbor”.”

That link is broken, but I did find another link that has the Forrest information.

https://news.thomasnet.com/companystory/tips-from-forrest-mfg-for-proper-care-of-circular-saw-blades-20001049

They state: “When installing a blade, operators need to be sure the machine is unplugged, that they wear heavy-duty gloves, and use caution in tightening the arbor. The guard should always be in place. Operators should never jam the blade with a wood block or bear down too much. This can deflect a blade tooth.”

I know that there will be a zillion anecdotal comments about never having a problem. I won’t jam my Woodworker II blades with blocks of wood when changing them. Too much money invested and replacing a tooth can’t be cheap.

Have your say...
