Handy Tools – Octagonal Guillotine
While building my octagonal box for the swap, I wanted to put some banding around the top of the box. This would mean cutting the ends of the banding at 67.5 degrees (90 – 22.5), and I figured I was unlikely to get that uniform with a saw (at least not without a nice miter box, which wasn't in the budget at the time), so I built a guillotine for cutting that angle. I used a couple scraps from around the shop, a hinge from the hardware store, and the blade from a utility knife.
The results were good enough that I used them on the top of my box straight off the guillotine.
It's a useful tool, and now hangs on the wall, waiting for my next octagonal project. I've since made a similar guillotine for cutting edge-banding for a hexagonal box. For some reason, I haven't yet made one for plain-old rectangular corners, though. Huh!
