Split Saw Nut Tool?

[Greg Crawford]

I've never come across any split nuts on a saw, but have read they need a special tool. I can't find anything more about the tool on SMC or on the web. Can anyone enlighten me on this? I don't want to pick up an old saw and not be able to take the handle off without destroying the nuts.

Thanks

The above link wil tell you all you need to know and maybe much more regarding split saw nuts and saws in general, assuming I did it right and the link works.

James,

That helped a great deal. I don't know if I can make one, as I don't have a way to harden metal, but I may be able to come up with something. I don't know why that didn't come up on Google.

Thanks,

Greg

Believe it or not I actually have a brace bit that appears to be designed for some form of slit nut, but it is too course for any saw I have with those in them. Glad I could help.

I had the problem of removing split nuts from a saw. It was suggested to make a tool to remove the nuts. I just got a cheapo large PM flat head screwdriver and filed a notch in the center. I then filed it a bit thinner to fit the nuts. It worked great.

You can purchase a hex drive spade bit, grind the end flat (being semi careful to not turn it blue, and then file a notch in the center. At least, as long as one has a hex drive handle (who doesn't <g>)--but even if not, a functional handle takes but minutes to make and the former spade bit can be epoxied in.

Take care, Mike

Check with Lie-Nielsen. I beleive they have a split nut saw screwdriver for sale in the MISC TOOLS section.

You can use an old saw blade.Cut with a cold chisel finish it with a file it worked for me.

Wow, lots of options. I love options, and SMC really opens the door to many that I never would have considered. Thanks, now I don't have to be afraid of a saw with split nuts.

I believe it. In the 19th century a standard set of 36 brace bits included a fork turnscrew bit - which was used for tightening split saw nuts. It was an important bit to the carpenter because with changes in weather it was (and is) not unusual for a handle to loosen. So having a standard bit to tighten it up made for good sense and much more satisfying sawing.

When we decided to make a dovetail saw with split nuts we knew that we also had to offer a driver for the screws, not just for routine maintenance but also for the kits. But we didn't like the idea of a costly separate tool. So in keeping with the tradition that the saw nut driver is just one more bit in a set of bits we decided to make the driver part of a modern sets of tools that just about everyone has - a 1/4" hex driver. So here it is - this is a prototype - production - which will have a better finish should be along in early September. One real bright side is that by just having a driver, we save a lot of money of handles and things so it will be cheap enough so it can be a low cost accessory not a major tool purchase (under 10 bucks). It will of course fit our saw nuts, I don't know about other makers.

I would go with the Lie-Nielsen version as was mentioned -- they are about $20.00, but sized to fit these screws and very nice maple handles. I have several for my planes and they are beautiful to use -- fits the cap-iron screw perfectly too so you do not ding it up when sharpening the blade.

Thanks!
