Well, the jig-saw cut dreadfully slow using a fine-toothed metal blade, but the bigger problem was that if I tried to follow a square clamped to the metal, the bottom of the blade would drift inwards, while the top tried to follow the guide. The result was a progresssivly worse angle.
When I tried running the jigsaw by hand, I could correct it, but that cause a wavey cut, and a very rough finish. |
