So I decided that I wanted a power case trimmer, after seeing how most where more spendy then I was, I took a good hard at these power trimmers and decided I could build one......ok now where to start.....well a look around my machine shop, I saw the Bridgeport, and my counter bore set, and I got it....<br>
<br>
<br>
<br>
Step one, place a .040 thick cardboard shim between the jaws on an old vise, grab a .375 end mill (cause that is rim size on a .223 Remington) center up between the jaws, and mill down .060, leaving a coounter bore to set and hold the sell in<br>
<br>
<br>
<br>
<br>
Ok, now grab a counter bore, install a .210 dia. pilot, and turn the machine on....<br>
<br>
<br>
<br>
<br>
Worked very well, and after just a few mins of work , I did a lots of shells.....and holds my over all leanth to plus or minus .001....success!<br>
