I’m building some radiator covers. A fairly simple design, the front is a 1×3 pine bipanel frame with two punched aluminum panel trimmed with some san modeling. The sides are glued up pine, as will the top be. I have about an inch vent cut on the front at the top and almost two inches cut out of the bottom. I’m using a biscuit cutter for the joints, screwing in the aluminum with self-tapping metal screws (the ones that look like they have a washer at the top) and a nail gun for the trim.
Couple of basics…I’m having some tearout cutting my 1×3s with my chopsaw. I took the blade off and tried to clean it up with some oven cleaner and a wire brush, but to no avail. Its a delta…is that a sign of a dull blade? Are chopsaw blades that come stock something that one would get sharpened or just replace?
For the vent and the bottom, I’m cutting a quarter circle out of the top and bottom corners. I tried using a jigsaw and after turning the blade speed down a bit and going pretty slow, I was able to cut a reasonably good quarter circle out. Is that what others would have done? I suppose a deep throated scroll saw would have done it, but I don’t own one. I own a used bandsaw…but I”m still learning how to tune it and the blade has quite a wobble and the cut looked pretty bad. Thoughts?
Thanks! I don’t have a ton of experience and am learning some basics as I go, well, with your help anyway!
