The new base I made for the FMT worried some people that it may not be safe. This is the setup to allow me to cut tenons on very long rails:
Some of the questions I received addressed how I would use this setup, and how safe it might be. Safety was paramount when I designed the new base; it is rigid (mortise and tenon construction), but light enough that I can lift it by myself onto the bench top:
Notice the cleats I screwed onto the bottom of the legs, and on the stretchers. These provide extra stability and peace of mind; they greatly reduce vibrations that could affect the stability of the table on the workbench.
Once on the bench top, I attach the table with the new Leigh bench-mount clamps, using the bench dog holes; I especially worried about table movement, especially if the table moved toward the back of the workbench. This could be a real problem; if the long work piece creates extra tension on the clamps holding the workpiece on the FMT, the workpiece could move. Possible result: Bad tenons, a no-no for this project.
The bench-mount clamps provided a neat solution. They have great holding power; the cam action has a long, reliable history, both on the Leigh D4, and on the FMT. Santa was good to me, and brought me one extra clamp of each model; I placed the clamps on the near front edge of the bench – one clamp on each side of the table:
The clamps on the back are trigger clamps, and have good holding ability. The spring-loaded and trigger action are great for this application. If any issues develop with these, I will install two Leigh surface mount clamps on the back of the bench, as there are no dog holes back there.
It was essential to have the FMT securely attached to the table at this working height. Since I started using the Leigh surface mount clamps on the workbench, it was natural to extend their use to this table:
Now I feel I have a very nice and safe clamping arrangement for the FMT at its new height. All that remains is a solid platform for me to stand on while cutting tenons on long rails. I think I have that one figured out.
