I modified Neil's attachment method for an extension table. I used some 3/4" aluminum angle iron to connect directly to the Kapex instead of connecting to the crown molding extensions. The nice thing about this method is that it just drops into place.
Here is a picture of the v slot on the Kapex:
Now with some angle iron in the v slot to show how it will work:
I cut a rabbet in the table to hold the angle iron and to get it to the correct height:
Here is the extension with the angle iron in place:
Final product ready for some finish:
Right now I haven't decided whether or not to clamp the extension table to the Kapex or just use gravity. The built in clamp will hold the extension table in place.
I use a cart for my Kapex made from parts of an old Sperry-Univac. This just happened to line up perfectly with my MFT 1080 with a piece of 3/4" plywood on top. So, I just line up the cart next to my MFT and use the MFT to hold my extension wing. This made it so I didn't have to come up with a support for the extension
