This is for those of you with Lyman Universal case trimmers that are sick of chamfering and deburring after trimming your cases. There is no cutter that does it all in one step for the Lyman, the RCBS 3-way which has different threads and the Forster 3 in 1 that fits thinner shafts than the Lyman are the only two (I think) that does this. So I bought the Forster 3 in 1 and had it milled out to roughly 14,5 mm internally to make it it fit the Lyman nicely. It only attaches with a set screw, so this works perfectly. A few pics:
