If any of you are familiar with the potato guns you make out of pvc and sparkers from gas grills you will appreciate this story.
I was drilling an african blackwood blank on my metal lathe. First I drilled a small pilot hole to depth, backed it out and loaded up a 31/64ths to drill the hole. Backed it out once to clean away debri. Tried to drill the second half of the hole without backing out (im lazy) and created a lot of heat and smoke (some how the blank survived). When I backed the bit out it was very tight and the minute it left the hole I heard a noise (like a potato gun going off, only smaller) and a large compacted wad of dust and shavings shot out of the hole like a bullet. Never had that happend before. Anyone else?
