Re: Changing Unisaw blades with 2 wrenches ?

I'm sure you will figure out how to get a wrench. But you should NOT need more than one, either to tighten or loosen the arbor nut. If your arbor nut is too tight right now, just use the clamp idea to loosen it. You should never have that problem again unless your hairy knuckled uncle borrows your saw.
In short, don't overtighten that nut. To remove the nut you should be able to stick any piece of scrap between a tooth and the table and easily break that nut loose. I use the end of my zero clearance insert, since it's already in my hand anyway. To tighten the nut, you should be able to hold a 10" blade by hand with plenty of torque to counteract your wrench hand.
I've never had an arbor nut loosen on me, and in the event of slip they are designed to slip in the tightening direction. Hence the left hand threads. Seems to me there are a bunch of guys around here so scared of their saw that they just gotta romp on that nut!

"Thin" wrenches (1/8" thick or so) are a standard mechanics tool - you should be able to find one in the size you need at any good tool store, or at worst you can get a set of Taiwanese ones for $10.00 or so. It's just a flat piece of steel shaped as an open end wrench.

Good grief, I really disagree with this. This is just a recipe for galling a good blade when you hit a knot or a tight spot. IME, not snugging your blade securely with a pair of wrenches or a block is a really bad idea.

Delta part number 955-01-050-1472
See the following diagram at: http://www.sawcenter.com/unipart1.htm and click the link for "Part Listings"
Knowing Delta, they likely want $89.95 for it, but hey, you never know, it might be $5 or so.....

I agree with the one wrench posters. No reason to overtighten the nut. Should come free easily. Gripping blade with two fingers (saw OFF) and then loosening nut is standard procedure. Using piece of wood to wedge the tooth is alright IF you dont overtighten nut. Never had 2nd wrench.

I don't know about the rest of you, but my Unisaw came with 2 wrenches, one for the nut and another to hold the shaft to the right of the blade.

Thanks so much to Mutt. That part number was exactly what I was looking for. Just to clarify - this is an old Unisaw I bought used, so the "inner" arbor wrench was lost a long time ago. Interestingly, I have the manual, which says to use a piece of wood to hold the blade while changing it, and the parts list doesn't show the inner arbor wrench.

Tom Gillespie notes:

The old Unisaws did not ocme with an inner arbor wrench that I've ever seen. Neither of mine did, certainly. The lbock of wood sufficed quite well until we all got too hoity-toity to do it that way.

Mine didn't come (new) with any wrenches at all. I finally cut out the most recent push stick design (Joat's?) and got to thinking in the shop yesterday that all Unisaws should be delivered with a pair of wenches...

Check page 7 of the manual. In the one I downloaded the picture shows the two wrenches being included. If you didn't get them, call Delta. Ed

Well, I'd feel pretty silly calling 'em up at this point. My 34-450 was delivered 29 years ago; and I'm still using the same old combination wrench to change blades. I'm not dissatisfied.
The original (defective, non-guaranteed) wench changed blades with excessive frequency and was retired early. I did a better job choosing saws (and wrenches!)

In that case, not only complain about the lack of wrenches, tell them the blade is about shot too. Ed

Y'know, I still have all the blades I've ever used. I share the blades between TS and RAS (resharpening as necessary); and don't think I have over a dozen blades. I'll have to check on Monday; but I'm not sure I ever used the factory blade at all.
I've cut mostly new softwoods and hadn't given it much thought; but the wreck has got me wondering: Is this typical? It rather sounds as if other people might be replacing their blades fairly frequently...
