I decided to skip the introductions forum and just get right to the question. Well, that's just rude of me. Sorry. Hi! My name's Robin, and I'm building some speaker cabinets. I've successfully made a few in the past, but I'm striving for a higher level of accuracy, now. I do plan to stick around and absorb as much knowledge as I can. I might possibly ask more questions!
Here's 3 things I'm stumped on right now:
Excess friction between the saw and work piece.
Streaking from the aluminum apparent on the work piece.
Problems getting a consistent angle across the board.
I've been trying to put some angles on the edges of 23/32" plywood. Earlier today, I made the first try with an old Skill saw that used to belong to my grandfather 10+ years ago. It had a little bit of corrosion on the base. While sliding it across the wood(smooth, sanded pine), I encountered random friction. The whole cut seemed more difficult than I felt was reasonable, but some areas were "sticky" enough that I had to really apply firm pressure to keep the saw from altering course. To counter this, I smoothed the base with some steel wool. The rough areas were then smooth to the touch, yet the friction was still a problem. The work holding the saw doesn't bother me, but the aluminum plate leaves gray streaks on the wood does.
The consistent angle problem is more serious to me than the other stuff. I noticed the base of the old saw was a tiny bit rickety. Thinking the course of action with the least hassle would be just to buy a new saw, I did. Bought a beautiful DeWalt. It's doing the same exact thing. Now, the first cut was amazing. Smooth travel, and the angle was consistent all the way. I felt good about my purchase! The second cut didn't turn out so well. Every cut I double check the guide position on both
ends of the board, before and after tightening the clamps. The position was exactly the same. Yet, on this second cut, rough travel, light grey streaks, and most importantly, uneven edge angle.
Start of the board is perfect.
End of the board makes me want to pull my hair out.
I checked the position again and everything's perfect. Except the cut.
