Machine Chuck Rebuild Part 2..

admin

OK now I finally got a chance to finish them up..Have to weld the surface up and re-machine it back to print spec..They measure 11.854 now..Print calls for 11.890 +.002 -.000Ready for the "treatment"..What I like to do is go around the key slot with a pass so I don't melt the sidewall and have to re-cut the key slot after..Now we start with the stitch weld..This is a good opportunity to practice "Doing them all the same"..There are 12 "dips" per stitch...In ALL of them..Ok here it is all done..On to the machining!!Next!...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:What better way to cool them off than throwing them outside this A.M.It was only 35 degrees so they cooled down fast..OK now..Indicate the bore..Indicate the face..After getting it as good as we can take a light chip off the face again..Now we can turn the shoulder to spec..12.150 + - .003It's also a good time to take a small clean up pass near the chuck for indicating purposes later..This now becomes the "outer edge"..One more time.....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:OK..Now we turn the piece around and indicate near the chuck dead nuts and indicate the "outer edge" dead nuts..That way there you know the face is running dead nuts also..Hint Hint..Machine to 12.150 and there we have it..Set the compound to the 45 degree angle and re-cut the lead edge and thats it!Not so hard afterall is it?I get all the fun jobs.....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:Nice work Zap
Reply:How long did the weld buildup take, and were you cooling or skip welding during the process?Lots of toys.
Reply:Looks good to me. I see you had to build it up .036, after the weld how much did you have to remove to get to your finished diameter? Couldnt have been a bunch. I guesstimate about .030-.040, just looking at it in the pics.
Reply:I bet your hand was KILLING you after all those welds. Man you're something else, I hope one day I can make my stuff look like that on purpose  It seems everytime i really try i turn it to pigeon poop, and everytime i just slack off and figure I'll pretty it up with a grinder it turns out flawless... LOL

Reply:Dumb question... does the bit skipping over the keyway cause issues?  Having never run a lathe... figured I better ask someone who has.More or less to satisfy my own curiosity.
