if you can't laugh at yourself something something...
last week:
rigid taping 5/8-11 on the lathe. turn around for a millisecond to acknowledge something help said to me and leave the drag on tailstock, locking up tight on reverse.
this spun the work in the collet, snapped the tang on the MT4 taper and wedged the tap in the chuck like i've never seen before.
tried all the usual stuff..
soaked in kroil overnight, wrapped body with brass shim and gaf tape and took a chain wrench to it. vibration while applying torque. nothing... and that was all while held in my 6" bullet with alu soft v jaws and me wrenching on the handle.
never seen one this stuck so next plan...
cut off wheel off the end of the tap and take it to the lathe. faced off and bored out with a brand new carbide endmill until the thin wall left of the tap cracked from jaw pressure.
endmill now gets seized in, something i guess i was kinda waiting for, but hoping wouldn't happen.. this now spins the albrecht body in my 3 jaw, galling the front serration on my jaws and putting a nice deep mark on this otherwise blemish free albrecht..
man this just keeps getting better! haha
in the end the chuck will be lovingly saved and it was glorious seeing that tap disintegrate.
pics show how much was left that wasn't chip form. lol
needless to say i guess it's time to rebuild an albrecht[emoji2359]
thought you all might get a laugh.
