Thumb screw knob

Recommended Posts

Hi everyone, Does anyone know if they sell wooden knobs to replace the thumb screw knob that tightens the blade down. I used to have a pattern that Steve Good put out for my DeWalt 788 but I can’t find it. I have a pegus now. Fingers are getting sore after a while. Anyone have a pattern. Thanks , Ralph

Is this the one you had from Steve?

A search for “thumb screw” on his blog gives a lot of articles he has done in regards to different ones, easier methods to try, etc. so may be worth a perusal through to get some other possible ideas or sources of different types of knobs to use. 
one idea he shared was switching to a round thumb screw offered by Seyco:

Also an old video he did on different ways to make more comfortable

This is just a few things he has shared over the years.

Thanks Melanie, the one I made was round. I think I can do something with one of those. I remember my thumb screw was glued into the wood knob and was permanent.  I think the Pegas knob is a little different.

Just be aware that with the knobs it's easy to over-tighten them and strip out the threads in the aluminum clamps.

Correct.  Over-tightening the clamp screws can also lead to spreading the clamp body apart, especially on Dewalt blade clamps.  I think these kinds of supplemental knobs are great for those with reduced grip strength and/or other physical issues that make it difficult to properly tighten the clamp screws, but if they are being used simply to solve the problem of blades slipping out of the clamps, then they can be problematic.

For that problem, I fold a piece of 220 sandpaper in half and slide it between the clamp screws every once in a while just enough to rough them up. Just a bit.

Oh how them days were Good.  MikeWorkshop was my Go To for FD blades and other.  The Knob showed in Paladin's Post is the kind I bought like 10 years or more and its still working Good.  I also do what OCtoolguy posted regularly.  Never Over Tighten the knob.  Learned real Quick way back then.  Anyway....  Danny  :+}
