Files included (5)
½ Sheet of good quality plywood. Preferable the same thickness as your workbench top.
2 3/8” x 3” carriage bolts (needs to be 4x the thickness of your plywood)
2 3/8” t-nuts
2 3/8” fender washers.
2 ¼” x 20 x 2” bolt (needs to be 2.5x the thickness of your plywood)
2 ¼” fender washer
2 ¼” nylon locknut
70 1-1/4” #8 wood screws
2 1-1/4” pieces of ½”OD 3/8”ID aluminum tubing for lifter bushings. I found this a one of the big box stores.
2 ¾ x ¼ 8 inch HDPE strips for slides, you could also use hardwood or anything that slides well.
6 #6 x ¾” wood screws for attaching sliders
Wood glue and super glue
Shaper Origin w/ ¼ bit and engraving bit, optionally you might want a 1/8” straight bit and collet and a ½ bit.
You can do all of the cutting with the SO, however I would recommend using a table or track saw for the straight cuts.
Drill / Driver, counter sink.
