Well the jig in the above photos survived another semester and saw plenty of use. The last two weeks I've helped students cut pockets for legs on the sides of her end table project at 20 degrees from vertical, helped a student cut tiny finger joints for her hexagonal themed kitchen spice and utensil rack at 30 degrees from horizontal, 30 or so sets of 90 degree finger joints both plain and very fancy. I had only one official class to teach so I offered to help any student who wanted to do some 3D carving or rotary axis work. Ended up with several takers.
As it is now I have yet to find anything I need to improve about this adjustable angle jig. We move into a new shop space in the fall and I plan to re-work the t-track bed on our Meteor, replace a failed limit switch on our Nebula, and maybe convince a new department head to buy me a comet and spindle upgrades for the dedicated CNC room in the shop.
