Hi Unregistered,
On July 29th, this site will be moving..! No, really - it's "moving" to another physical location - including servers, gateways, routers - everything - including my coffee cup...
So, from the date of July 29th through July 30 or 31 (shooting for these dates, but - as always, I'm at the mercy of my ISP who has to install the lines to the new location - and we actually get them running ;) ). But - this site, cloud servers and main web will be OFF LINE.
Now, please save these dates!! Please - don't be "that guy" who emails me on the 30th to tell me you "can't open the Parker Website". I'll already know it is offline - and also know that you are "that guy"...
I'll take this notice up and down over the next week or so - and leave it up during the final few days before shutting it off on the 29th..
John D.

I have roll crimped with both a hand drill and a big drill press and they both work easily with any of an assortment of 1, 2 and 4 roller crimpers. None of them are ever tightened more than slightly finder tignt and can be held in place on a table top by hand holding. I think the secret is simply use a jaw that fits, lube the crimper and run 300-500 rpm. I use my stationary dril press set at about this speed because that particular press is used mostly for metal work and has an x-y vise permanently mounted. I have quit using the actual crimping vice. I simply clamp the hull jaws between the drill press vice jaws and center the first hell under the crimper. From there on I can even change gauges and not have to adjust anything.

610rpms is the lowest mine goes, using a hand drill I have done it and extremely slow speeds like a hand cranked roll crimper does which work well also. I couldnt do the 10 ga hulls by hand they would just spin the 8 gauge is much easier though.
I really need to get to the range soon and do some patterning testing on all these loads.
