Re: [CAD_CAM_EDM_DRO] Re: EMC (I want...)

If your wanting to build quick take down barrels, I can suggest a much
better way that is stronger, much easier to build and is adjustable for
barrel wear. I got it from the retired instructor at TSJC.
He's got over 40 years in the business so he has a pretty good idea of what
he's talking about.

Please contact me off list about this vis Smoke@...
