Being pretty unsatisfied about the low availability of most of the cool hardware in Canada, in particular, the thumbscrew.. I decided to build my own out of wood and a stainless steel bolt 2"... They are actually quite strong, and they will do the job for my custom wooden rotating ring I am currently building for my grab and go 6" Newtonian.

 

These are the thumbscrews, not too complicated to build but a drill press is required. (I receive one for my upcoming birthday, explaining the sudden crafting outburst lol.gif)

 

The bolt is a standard 1/4" diameter (NC20 I believe) x 2"  the longest part was to carve the hex shape in the wood but it gives great satisfaction at the end. The bolt was sunk into epoxy and carpenter's glue for the top cap.

 

The epoxy is sticking pretty well on the stainless, I tried to destroy one and some wood won't come off the stainless, I had to use a sharp blade to cut it off.

 

Tomorrow I'll pass them on the belt sander to round the edges and apply some varnish on the wood.  (;

Nice.  I've been thinking about doing something similar.  I had wondered about how well the epoxy would bond to the other components, and you've answered that.

 

I assume you cut cylinders from a wood dowel for the knob parts.

 

I got my wife a drill press years ago for her birthday.  On my next birthday she got me a Cuisinart food processor...

This is my new final thumbscrew concept with varnish.  They are pretty solid, I think they are going to do the job and for those who perhaps want to built their own. (Could happen)
