Re: Lyman universal case trimmer
The crank on lyman's case trimmer is riveted to both the shaft and knob, if you grind or drill off the riveted heads they will come apart. But then it will be kinda hard to get 'em back together.
When Lyman designed that device, some fourty or more years ago, the idea of hooking up an electric drill to the shaft had not come up. So, when it did, they produced an accessory shaft so it can be done. ??
Lyman's customer service is spotty, depending a bit on who answers the phone on any given day. I've never had a failure so I have no direct experience but they do have a warrantee time limit and seem to stick to it. Not sure that's a bad thing because they would have to charge as much as RCBS/Dillon does so the 'free parts for life' would be paid for at purchase if they went that way. ??
