Because of the interest in the disappearing table, i set about designing a expanding side that could be easily made, that may be relative, using only the tablesaw for a major machine. I simply built it up in pieces. I only made a single sided one, but would have to be double sided as the diagram shows for multiple slides. The one I made is quite sturdy and slides easily. It could be used for any expanding table.
I first cut a thin board for the center web, then square corner pieces. The material in one corner for the 1/8 plywood was removed with the same blade on the tablesaw, one cut plus abit to have sliding clearance. I then cut a strip of 1/8 ply for a spacer strip to glue corner pieces on. Nails where used so pieces would not slip while clamping. remove strip right away so it does not get glued in.
I made an I section for the guide slider, but as I found out later I only needed a T section, as I in drew in the diagram. I had made a full length piece and used the sides for alignement and clamping force with clamps. Use 1/4 to 1/3 length of the slide for this piece. Screw and glue each piece to opposite ends of each side.
Assemble, sand clearances where necessary, a stop is needed at one end so it does not slide past the end when pushing together. The bought one used a metal pin, I used a screw and plastic tubing, wood dowel would work good. Whatever you have.
I hope what I have said makes sense, and the diagram you can see. I think you get the basic idea, just experiment, you may have a better solution, Cut as much material at one time so parts are the same side. Before going all out make one sample, as you may not want to continue.
To make the expanding table you need 10 double pieces for each side. They measure `15 inches long and only 1 1/4 wide. I think I would make it alittle larger cross section. Don’t make the clearances to tight, dry wood needed.
Thanks for looking, I hope this info. will be helpful for anyone interested in making slides.
Comments, suggestions, questions appreciated.

I’d like to feature this on the next episode of “Behind the Sawdust” during our projects segment. We’ll just show a couple of your photos and tell them who made it. Do you mind?
