Just finished up making three pencil boxes for the grandkids, found the project in an old American Woodworker. Spent a good bit of time working on the jig. I did make one box out of pine 2x4 scraps first just to prove to myself that the jig worked. The boxes are 10" x 2" x 2" made from Mahogany (maybe) with Maple lids. The top and bottom was one 2" x 1" stick for routing, then cut into three pieces, and finally two pieces glued together to make the fixed section. I used a plunge router with a 1/2" spiral bit to route out the cavities and a 5/8" dovetail bit to cut the chamfer for the lid to slide into. Made the lids on the table saw. Final fit and finish was done with a bench plane and a low angle block plane. Need to be very cautions, that Neander stuff is kind of interesting. 8^) They are finished with six coats of Behr's Tung Oil and several coats of wax.
Slide the lid back past the joint and the top section swings out. The pivot is a brass screw.
The lid slides completely out of the top.
I don't know that kids even use pencil boxes anymore, but I enjoyed the project. They will be visiting in a couple of weeks, so I'll soon find out.
