I decided that I had to come up with another solution to the milling task. I saw examples on You Tube that one could mill with a drill press. So, I bought a cheap....inexpensive..... 4"cross slide vise off ebay for $41 shipped. I used a 3/8" 4 flute end mill and a woodruff cutter I had. Milling the main slot took two passes. Seems too shallow causes more 'chatter', so I made the 2nd pass a little deeper. I had to tighten the gibs on the vise to lessen vibration. Suffice it to say: it can be done! A mention as to length on the block, make it long enough to carry the flats on the forearm. Also, if you try this for the first time, make sure to wear eye protection and gloves won't hurt! The milling.....maybe because of inexperience or the inability to control speed on the drill press adequately, a million tiny, wee, small, splinters of steel are thrown about. I still have to make another pass on one side with the woodruff cutter. It's getting very near decision time for getting barrels. Haven't decided which way to go. I thinking I'd like 416 Rigby on the one hand, or 45-70 on the other......I have a Ruger #1 in 416 and like the round!

Spent a couple hours picking out microscopic splinters JUST by picking the block up from the vise
