First of all, thanks to you guys and this fantastic community! With all your input and suggestions, I was able to design, and have built, a great table top watchmakers bench. Here's some pics of the completed project:
The wrist rests work perfectly (after I hacked them apart with a saw to mount them!). They are super comfortable and are positioned perfectly! They come off and stow away nicely in the drawer below. I am still waiting for the brass hardware to come and then it will be complete.
