ok feet first they are bolted through top and bottom with 6 inch Timber lock style screws I only did half lap joints on the top corners the rest were timber lock screws, two, so they wont twist. (yes I got lazy) but the whole thing is very square flush and level. I got the handles on amazon
Handwheel
$13.28 for two.
i used acme thread 5/8-8 i got six feet of it for about Threaded Rod, Low Carbon Steel, 5/8-8x6 ft
thirty bucks.
I used 8 quarter rock maple for the movable jaw and then laminated a piece maple onto that jaw so that it missed the fence on the mounting board. I plan to add t tracks to that board. then reinstall it to the frame as it is now. When I finish mounting the top you will not even know it has vertical holding. This table is turning out to cost plenty. I got 2 sheets of 3/4" MDF today at sixty-one bucks each and a sheet of haff inch plywood for the bottom shelf and that was 35 bucks, so even though I had most of the 4x4’s left over from another project I will still end up spending a bundle on the raw table, not to mention all the accessories and upgrades with the machine and dust collection. Turns out that the machine itself is only about half what you are going to spend on CNC.
