Last years project was a pirate chest / toy box project that started out casually with no set schedule for completion or any other requirements and turned into a project with a (grandson's) first birthday deadline and central theme of the first birthday party. Whew...what pressure! With that experience I vowed that all future projects would be "secret" projects, revealed (to my family) only when completion was eminent so the pressure of a deadline would not occur. With the grandson's second birthday approaching I very secretly started an ABC blocks and carrier project, suspecting that it would be a much smaller and simpler project than the last.
Oh boy. I underestimated the difficulty of a six sided carve...on 36 separate blocks. Ever done a "double sided" carve ? Well this is a double sided carve times three. It's not so hard to make up a .mpc file with abc's and 123's...but to construct a sled that will hold 36 blocks rigidly, perfectly square, perfectly in location and with perfect repeatability proved to be uh...quite challenging. So after a few failed attempts I used some bolt and nut "clamps" to tighten the blocks in place and after some shimming and experimenting I got the carving "close". The photos are of some of the "failures" and of the final (unsanded or finished) blocks and the sled. Also a photo of the carrier box that will eventually sport wheels and a pull rope.
Basics are the blocks are 2-1/2" cubes of hard maple. Note I carved the top and bottom without the square carve area as I carved the sides too deep and would "disconnect" the inner cube if the top and bottom were the same. I've corrected the .mpc files to fix that. When completed I'll post more photos, the .mpc files and some improvements I would make to attempt this again.
Oh and apparently there's another grandchild on the way so next year should be double the fun...
