Producing tenons on dining chair front legs

The front legs on our dining chairs pass through the seats and are wedged.  To produce round tenons on these legs, we first cut square ones on the table saw to remove most of the wood.

We have modified a two spindle Newton boring machine to cut round tenons.  This machine was made for doweling.  We changed the pulleys to slow the rotation and built fixtures to hold the various legs that we tenon.  Austin is adjusting the fixture to center the cutter on the tenon.

After tenoning, we taper the legs and saw a kerf to receive a wedge at assembly.

Stroke sanding a table top

After working on a 4’ wide by 16’ long table last month, our standard 7’ long Mitchell Trestle Table top is easy (relatively) for Aaron to handle and finish sand on the stroke sander.  We built this sander of wood and tailored it to our products and needs.

    Hi, I just came across your blog and it’s a wealth of great information and techniques. You make beautiful work. Any chance you could elaborate on your use of the newton boring machine as a round-end tenoner? There is one for sale local to me and it would be great if it could serve multiple purposes. Thanks, Anthony
