Brass

Thanks for the replies, In this pic I had it set up to drill 30cal brass " a brass tube gets glued in the casing" it works good for that. I guess I'll be looking for one that is solid. I have a 5c collet indexer but it is to large for what I'm doing.
This collet closer was clamped in mill vice at 45deg for the bottle openers. I do have some e collets I'll taper one next time I have lathe going, would that be done with collet closed in the spindle and a boring bar ?.

Here is the setup , the E collet is tapered to fit caseing, This run I'm using a 1/4" ball two flute "don't have ball 4 flute"
They are turning out ok with two passes.
Thanks for all the advice

I'd be tempted to try a slotting cutter on an arbor rather than an end mill. Cost more, true, but would not have the same problem.
 
Would that be a 1/4" thick slotting cutter, I have some slotting cutters but not that thick ?. This time I used a ball mill for the round corner affect , with two passes they are turning out good ,besides I like loading them in front of the cutter anyhow so I have to make two passes ,2nd pass I'm taking.010 off
Thanks

I was thinking full width, one pass. But if you're happy with the ball nose, go for it. A full radius slotting cutter is available, but naturally, cost goes up.
 
Thanks , mabey I'm confused I thought of a slotting cutter as a small saw blade with an arbor thru it, is that a spline cutter / slot cutter ? , I have a bunch of them but all are thinner.
Or is there a different type cutter I haven't seen yet ?.
Thanks

I'm gona ware out my poor mill with these and 30cal caseing, it would be nice to cut 5-8 with one pass
I'm thinking make aluminum fixture
Any suggestions
Thanks
 
Sounds like a plan to me. If the repetition is that often a Fixture is long overdue.

Started a fixture, it holds four caseings , still need to put a couple 1/4-28 allens to lock the rotation then dowell pin it at the rite angle ,it will be held in a descent x-y travel vice going to try it on a DP with threaded chuck , as I don't want to do these on mill anymore , have a new four flute ball mill image.jpg they are only brass I'm thinking it should work , what you think ?.
