How can I square up slots cut with a circular saw?












2















I used a drop-saw to create these slots:



enter image description here



Due to the circular blade, it's obviously left a bit of the wood in place, more easily seen here:



enter image description here



My question is how can I clean up these slots? I've considered filing, of course, and I'd be happy to buy a file that fits if that's the best option. But there's a lot of wood there and I think filing would take a long time.



I also thought of chiseling. Again, I don't have a chisel that fits, but am happy to purchase. However, I can't see how it would actually work. Sure, I could chisel the sides of the slot, but then how would I actually knock the bit of wood out? I'd need a tiny chisel to fit the slot - 5mm or less.



Are there other options?

          Use a hand saw on either side to take the sides all the way down to full depth, then a chisel to remove what's left between the two saw cuts.

          A handsaw or jigsaw does the job, but it usually results in visibly less sharp final cuts. It's very difficult to keep perfectly parallel, and you usually have more tearout with those saws.



          I'll often simply raise the blade back up partway and tilt the front of the workpiece upward to square it with the cutting arc of the blade. It'll help to have a cut mark on the underside of the piece as well.



          Move slowly, alternately watching the upper and lower faces of the board to check cut depth. Adjust blade height and board angle incrementally until the right combination is found.



          Brace the workpiece against the fence or use a jig block to prevent it from shifting sideways. Keep the blade spinning at full speed while it's engaged with the workpiece to prevent grab, saw jump, and tearout.

            But before buying one of those, I would try coarse sandpaper wrapped around a piece of wood that just fits into the slot. Either that or a rasp (the name for a wood file).
