Using 3/4" inch stock, with the Kreg Jig set at 3/4", the 1-1/4" screw protrudes out the side. Has anyone else had this problem?
Check your collar depth setting an your jig setting, make sure they are both set for 3/4.If you are using 3/4 stock you should not come out the side. You say the jig is set at 3/4 but you dont mention the collar on the drill bit, it also has to be set.
The other thing that happens to me from time to time is that I have the screw at too much of an angle so when I drill the screw it ends up coming through the wood.
Same thing happened to me the first time I tried to use the jig to fix a plaque. Had to buy a new plaque for the school. I didn't realize that the screws had to be so well-seated into the small part of the pilot hole. The screws tap so well that they will go in whatever direction they are initially pointed. Since then, I haven't had a bit of trouble.
