Botch Posted October 31 Report Share Posted October 31 Yesterday I was using my ~1993 Delta bench-model drill press, when at its highest speed the chuck fell off, was a bit startled. That chuck has never been off the press before. I know with a morse taper you're supposed to just slide it back on with great vigor. I did, and it fell off again with the next hole. This time I wiped off the spindle (already looked clean) plus the hole in the chuck with a Q-tip, pushed it back on, then pressed the chuck down into a piece of wood with the arm as firmly as I dared. It fell off again with the next hole (fortunately the last one). I know I have the owner's manual packed away somewhere, but that could take hours; thought I'd ask you guys. Is there a step or a trick I'm missing? TIA 1 Quote Link to comment Share on other sites More sharing options...
drzaius Posted October 31 Report Share Posted October 31 Give the end of the chuck a good whack with a wooden mallet to seat is securely. Thoroughly clean the mating surfaces first. Quote Link to comment Share on other sites More sharing options...
gee-dub Posted October 31 Report Share Posted October 31 Yep. I use naphtha (Ronsen lighter fluid) but alcohol will work as well. Make sure the shaft and socket are clean, clean, clean. Wind the chuck so that the jaws are recessed inside the housing. Slip the taper into the receiver hold a block of wood against it for protection and give it a whack with a mallet. Check for alignment. If you're lucky it will be fine right off. If not, use the drift key to take it out, rotate a few degrees and re-whack . . . that is a word, right? 2 Quote Link to comment Share on other sites More sharing options...
Von Posted November 1 Report Share Posted November 1 On my ~2000 Delta Drill Press (a DP200) I don't believe you use a drift key (I had to look up what that was). The spindle is fixed and the chuck friction fits on the end of it (e.g. video). 1 Quote Link to comment Share on other sites More sharing options...
Mark J Posted November 1 Report Share Posted November 1 As above. Make sure the the solvent has completely evaporated and leaves no residue. 1 Quote Link to comment Share on other sites More sharing options...
