I am building a table top out of 4 edge glued boards. 2 of the corners have a radius to them. I have a piece of MDF that I am using as a template, with a trim bit and about 1/8 to 1/4 overhang rough cut with a jigsaw. I am moving around the edge counter-clockwise. As I cam up the left end and round the turn around the first radius, suddenly the router "caught" and a hunk of the edge tore loose. I moved past it and completed the rest of the cut around the edge without incident. I glued the broken piece in and it isn't noticible, but now I have to match the edge and I'm leary of using the rounter on it.
My theory is that that point of the cut was just too thick and I was taking too much off at one time, and perhaps the grain was funny there. The way I want to proceed once the glue has been on for 24 hours is to sand the offending piece down to about 1/16" from the template and then route that off.
Thoughts?
