I finally got most ly my Myflrd ML7 back together (Feed gears waiting for some housing bolts)=20
I decided to do a rough alighment test with some 1" aluminum bar stock. I set about 10" in the chuck, with the other end supported by a live center in the tailstock. =20
The problem: After a finishing pass, if I make successive passes down the bar without touching the crossfeed or compound knobs, it takes off more chips on every pass. I've done as many as ten additional passes, and it shaves off more every time. =20
I thought it might be due to thermal expansion, so, after one pass, I cooled the bar with some alcohol on a rag, and then cranked the carriage across one more time, and it took off more material. (!) =20
The cross and compound feed knobs hold position, they're not creeping inward. If there were slop in the carriage, I'd expect it to perhaps take off additional material when traversing in one direction, but not the other. If I let the carriage sit in one place, it stops producing shavings after about 30 seconds, so the creep only seems to occur with carriage movement. =20
Does anyone have any idea what's happening? =20
