Screwing into end grain

When screwing into end grain of wood, cant the lack of strength be countered with some glue? If you pre-drilled the hole, and put a couple of drops of glue in it - regardless of whether it carpenter's, polyurethane glue, or a liquid nails type - wouldnt that bond to the wood and secure the screw?

i would expect that to be very strong - is that not right?

Of course, you couldnt unscrew this very easily but in a spot where you didnt plan to remove the screws, is it a reasonable approach?

The screws action will just force out the glue. A long screw (3-3 1/2") should be adequate to accommodate screwing with the grain. If you use any glue at all only use liquid nails.

If you are really worried about end grain splitting or damage, drill a 1/2" hole in the area where you want the screw(s) to go, insert a 1/2" dowel the depth of the hole you drilled (probably not longer than the screw), glue the dowel in as you go, wait for it all to dry, predrill the hole for the screw and insert it.

You mean use the dowel like a cross dowel, right? Otherwise youd just be scewing into the dowels end grain.... did I understand correctly.

Either way, really. If you use an oak dowel, their end grain is a little tougher than lighter ones like pine, etc. Pre drilling will keep down splitting.
