I just purchased a bench top delta mortiser and went to try it out to make sure everything worked ok. I had borowed the same machine from a friend to make a bed for my grandson and it worked pretty well so I decided to get one of my own since I have orders for two more beds (granddaughters). Set the machine up, put the drill and chisel in like I did with my friends machine and when I started drilling the bit would not come back out of the wood (white oak) I tried some soft red cedar, same result. Tried to sand the bit with some 600 grit wet dry, same result. What's going on fellas?? My friend said he never had this problem. I have to actully take a hammer and knock the bit out of the wood. Help me!
