Shin, It’s pretty simple. The mini grinder mounts on a small sheet of 1/8" aluminium with a bolt through the plate into the threaded handle hole in the grinder. That is screwed to the base. The “table” is another aluminium plate attached with a hinge and the adjusting legs are fastened with thumb screws into insert nuts in the base.

Dutchy, There is no cooling. :-)
