I've been working on chair parts with compound angle mortises, and I got tired of shims and wedges and whatnot. I found a cast-iron bandsaw trunnion on grizzly.com (Model H8193) and retrofitted it to my Laguna LBM 200 horizontal mortiser. I had to make a couple of adapter plates to mount it, but it all worked out pretty well (see photos below). Now I can tilt the table to any angle, which also tilts the clamps and miter gauge along with it. Much better! The stack height of the trunnion and two 1/4" adapter plates used up about 4.5" of vertical travel, but I still have enough left for most jobs. At some point I may put a riser block under the motor if I need more clearance.
