Monday, October 3: Took another day off, taking Wednesday off too (I have a lot of vacation time, as I don't take vacations).
I didn't get quite as much done today as I should have. I spent the morning picking up furring strips and a few electrical supplies, put together the hot wire cutter:
Yes, it looks extremely dangerous. This part of the device is fairly safe, however. It is the business end that carries a shock hazard. Eventually I'll package this up, but just don't have the time.
This is the cutter I made:
It works - but is slow. It takes about 2 minutes to cut a board - not bad, but tedious. Also, though the foam board is "square" it isn't perfect - the middle of the boards is thicker, and my guide had trouble moving the full length.
I needed to refine my wire-holding setup, so instead of making a second guide I decided to cut the other side of the board with the saw. Messy and a pain, but I got all of the boards cut for tomorrow and Wednesday.
