Crazy idea...Wilson trimmer tri-way cutter?

[vonb]

I love my Wilson trimmer but have replaced it with other trimmers due to efficiency. With that said, has anyone attempted to modify the Wilson cutter head to provide a tri-way trim on brass. The thought would be to trim, chamfer and debur in one pass. I'm thinking something similar to one of Giraud's cutter heads milled into the front of the Wilson shaft.

My Henderson also does all three in one trimming pass. It's expensive, but awesome (if you can afford it).

I have a Giraud now. However, there are times when I'm doing a smaller batch of brass and don't want to swap out the cutter and shoulder die on the Giraud. I'd like to use the same carbide cutter in the Wilson.

I have one of these and it works great:

It’s probably mostly like hoping your clothes will be ironed when you pull them out of the dryer.

Just to confirm, the Forster 3-in-1 fits on the Wilson trimmer, or you have an entire Forster unit?

I have a Forster trimmer. I don't know if the trimmer shafts are the same dia.

It’s not that important to me but it would be beneficial to do all three in one pass provided it gave the angle you wanted. If I was you and it was that important to me I would have a tool and die man make me one that would fit my Wilson

Thats the beauty of the Henderson only takes a minute to change caliber/cutter head.

To get a truly even and square cut the part your cutting needs to turn unless alignment is perfect. Your cutter would have to be square to the neck and in line with the center of the neck. There could be no error in the case holder and no run out in the case either. Not going to happen. Now if the case spins then all of the misalignment issues go away as the are evened out in one turn of the case. You can do this with a Giraud, just spin the case while its cutting enough for it to make one full rev. The piloted turners are ok but can cause accuracy issues if they disturb the carbon layer in the neck. When you have un ever chamfer or necks not cut square your bullets seat with more runout.

Alex,
How can you accurately measure if your necks are 100% square?

Its not easy. A quick check is to grab one in a caliper like your measuring the trim length and spin it. If it wants to pivot on one point on the neck, thats the longer part of the neck and your not square. Its not a measurment but its a quick check. To measure it you could set it up in a vblock and spin it with an indicator. But the caliper trick is good enough imo.

Thanks Alex,
The v block was what I was thinking but I’ll try the caliper as well.
