... Do any of you using a closed end mandrel have to deal with run-out?
I bought one for a Statesman and tried to use my Jacobs Chuck and have too much run-out. Drill bits run straight and true. I have fiddled with it for waaaaay toooo long and cannot find a "sweet spot" (thinking that the two flats for the wrench might be the culprit) so, I am assuming that a collet is the best way to hold the bugger![}]
