I’m building picture frames and I ran the four sides through the router table using a straight bit to cut the rabbets (recesses) to hold the art content, then I cut the miters on all corners. So at this point I basically have 4 wooden spears, sharpened on both ends.
I messed up pretty badly on my measuring (maybe measured only once and cut once :) and the rabbets are about 1/8” too narrow.
I have this strong urge to adjust the fence to widen the rabbet and run the mitered pieces through again, pointy ends and all. There’s not much material to remove and it seems like a quick operation.
But the instincts are saying “not good!” Partly because I don’t know what effect the sharpened miter will have when contacting the router bit and partly because if something goes wrong, the wooden spear will be flying around the shop at high speed. (and although this shouldn’t be weighing in on the decision, the wood was cheap, so I can scrap it or use for a smaller frame and will have learned something.)
Is there a safe way to widen the rabbet of the already mitered corner pieces on the router table? Is there a hand tool alternative that’s safer? The plane I have wouldn’t allow me to get close enough to the inner edge of the rabbet. Chiseling could be pretty ugly.
Also, the other question I have is about widening a dado on the router table. It seems like you’d want to do that by making the additional widening passes against the material closest to the fence, rather than on the side of the dado further away from the fence?
In the second case, it seems like the bit would tend to push the piece toward the material-less already-cut dado, rather than firmly against the fence…
Thanks for your thoughts on this.
