It's been many years since I've had one of these. And I threw that one away! But looking at John Nixon using one to make edge jointed legs, I thought I'd try it again. The bit & block from MLCS arrived yesterday and I fiqured I make a box for it as a test piece. Nixon has a good video as does MLCS. And when they 'mentioned' tearout; well they coulda' at least raised their voices a little! It's a big bit with a radical geometry and will rip the living @&% off the back edge if it's not supported TIGHTLY. I made this little box today and left the tearout where it is to remind me 6 months from now. Don't even buy this bit without the approiate setup block. MLCS makes one for each size bit. With the block, the very first cut was right on the money for both pieces. Here's some pix showing tearout and non-tearout. All tearout happens as the piece comes off the bit and after I realized hand clamping wasn't gonna get, the rest was made clamped to the push/backing pad.
