howdy hey. long time sense ive been in here. illness has me hurt . any who ive a four jaw (el cheapo) that i got through flea bay (ya i know ) three jaws work great but the fourth now so good at all in fact i threw it into the scrap box. im trying to maybe salvage it but unsure of how .the part that holds the screw into the chuck is bad (the whole design is junk )it binds up so bad that i cant use it at all. thought about making a new screw piece for it but unsure how to keep it in the chuck as the original one is press fit and useless. any ideas as to what to do or maybe trans form this chuck into something else. its for a lil 7x12 i need to order a new 4 jaw from little machine shop when i get some money , but for now id sure like to salvage this junk .
