The slotted spacer being held by the bar nuts holding the saw to this stand has bothered me since it all came together. I figured some special nuts would be a lot easier to use, here is what I came up with. You can see the spacer I was using in one of the shots above, it is not bad but it is kind of a pain. I will keep it for use if I need it for a saw with different size threads. I made two sizes of nuts 5/16" and 3/8" for the Homelites I have. One side of each nut is recessed as the bar studs are not threaded all the way and a standard nut with out the bar in place will not tighten on the bracket of the stand. I marked the nuts with a 5 or a 3 on the non working end and on two flats near the working end. The nuts are made from 3/4" hex aluminum so that the same wrench fits the nuts on the 1/2" bolts clamping the joints in the stand. I use aluminum because it was easy to come by but they might be better out of steel. They might gall and wear the stand. If they don't work out, I will have to make new ones. I have only used the new nuts on one saw but I like them already.

The welding of the washers to the bolts to keep them from turning did not turn out well, so I had to redesign. They work fine, just look terrible.
My original plan was to build it so anyone with a hacksaw, a drill, and a sander could reproduce it. Well, they still could be I suppose but the bolts need to be fixed so a single wrench can be used to secure the saw in position. That leaves the other hand free to hang onto the saw so it is actually where you want it when the bolt comes tight.
My current plan involves milling radiused notches in the heads of the 1/2" bolts and installing 1/4-20 socket head screws close beside the bigger bolts to prevent rotation. I guess this is trading off of welding for a milling machine. Of course a grinder could be used to make the notches. The socket heads are round so they fit in the milled notches very nicely and secure the bolts from turning.
Looks much better. I am finally happy with everything about it.

Yet another thing on the "someday" list. How about carriage bolts to keep them from turning? Anybody could easily drill the hole and square it with a file. Or, an eccentric cam on a pivot that engages the bolt head and presses harder the more it tries to turn.

Is it just me that can't see the images in lesorubcheek's original posts? All I get is a thing from Photobucket about updating an account. I assume it just cause the post is so old and it's third party hosting.

Or, an eccentric cam on a pivot that engages the bolt head and presses harder the more it tries to turn. [/quote] Good ideas there. Squaring the hole and carriage bolts sounds workable, I could not find bolts short enough and I did not want to rethread them for some reason... I got on hex bolts and got tunnel vision perhaps. The eccentric thing sounds more difficult to pull off to me. A guy might just install a small hex head though, close to the big bolt, threaded into the plate. Then install the big bolt so the two touch on the flats. There would be not turning force to spin the small one and it would hold the big one. I do think that could work. I have some parts left, maybe I will try that. I am just not big on carriage bolts in metal I guess.
