Easiest way to chamfer inside of necks

[Mordamer]

I need to chamfer the inside of thousands of case necks on 25 GT and 6 Dasher virgin brass. The only operation I need to do to the brass is inside chamfer. I have two boys ages 6 and 8 that love to help me reload. Right now my only method is a cordless drill with a VLD chamfer tool chucked in it. The boys have a hard time doing a consistent chamfer with the drill and I can tell it's just a matter of time until their fingers slip off the brass and get cut on the chamfer tool.

What is the absolute easiest way that is fairly child friendly to do this operation?

I'm thinking some kind of case prep tool that aligns the brass in a pilot and goes to the same depth off the shoulder every time.

Giraud, you can set it to just kiss the chamfer and not take off the actual length, aligns on the shoulder.
Once you set it up they cant really mess it up and you just push in and half a twist and its done. Give em some gloves just general finger soreness and let them know they cant leave until the box is done.
Any three way should work basically the same but giraud is all relatively protected on a bench model so they dont have to hold anything and child... resistant.

Frankford case prep tool. Not hard to be consistent. My daughter helps me just fine.

Something like a WFT2 trimmer and replace the end mill with a chamfer mill

This.

I can see your concern as a drill can spin pretty fast even on a low setting. Lyman prep center or something similar that turns a VLD chamfer tool at lower RPMs. Takes about 3 count with light pressure to get a decent chamfer.

I use a modified Henderson style trimmer which does trim and all the other functions. And then I have redundant tools set up on an annealer from burstfire.

I just want to say that this post makes me super happy to see as someone who has a 5-month-old. I can't wait until my son is old enough to start doing some reloading functions.

Giraud

A Harbor Freight drill press with depth stop set on the slowest speed.
Chuck your VLD chamfer tool in and have one boy raise n lower it while the other swaps out the brass.
Make a v shaped guide that can be bolted down to the table so the position of the brass is in the same place every time.

Actually, the very, very, very bestest solution is…wait for it….a friend with a Giraud. Lolololol.
