Collet quality

[TORQUIN]

Forgot to reply to this.
Re-threading the drawbar and collet worked for me.
One last question: When I remove a collet, I fully unscrew the drawbar out of it before using my mallot to bang the collect out of the spindle via hitting the top of the drawbar. Should I instead leave the drawbar somewhat threaded into the collect when using the mallot?

Yes, always have the draw bar engaging the threads, at least 3, but more if possible, when hitting it to loosen the collet. If you are all the way out the draw bar will bend the first thread, making it difficult to thread in the draw bar next time.

Yep, I only back mine out a single turn or so before giving it a sharp rap.
