Any idea what this is?

[Ohio686]

I received this in a large lot of reloading equipment. Any idea what this is and what it is used for?

[Conditor22]

Is that 1 piece or e pieces?
the top piece looks like the case holder on a layman universal case trimmer

[lightman]

It looks like the chuck from a Lyman case trimmer that someone adapted for use in a drill press.

[Ohio686]

There is the shell holder assembly. Then two other bases attached underneath

[Conditor22]

I the big (bottom) ring hollow or solid?
Does it have clamp marks on it?

Unless you have a drill press with super fine depth adjustment I'd only use this for roughing in brass for case conversions.

Lyman used to sell that unit as a drillpress case trimmer. I've had one for more years than I can remember, and finally wore out the jaws. The cutter is a separate piece that goes in the chuck on the drillpress, and you used the stop on the drillpress to set the length of the case.

Hope this helps.

That's neat, thanks for sharing. I sent you a private message in regards to it.

Using a drill press for case trimming. That’s actually an interesting idea.

Forester has a drill press setup , I assume they still offer it.

[Bazoo]

I think in the Lyman 46 manual is a little advertisement for that thing. I don't know how many they made but it's not something you see every day.

[Ohio686]

It has sat in a pile of stuff for a long time so now it has found a new home with Bazoo. Thanks for the responses.

I have a newer version of it.

I have noticed as suggested by Conditor22 that the cut length is not to be trusted down to “frog hairs”. I stop short and then finish cutting on a regular case trimmer.

Yup, I've got a newer version, the little arms are spring loaded to fit different size brass, you pop it in there then turn the little lever to swivel the whole contraption down to hold the brass in place, the more you turn the arm the tighter it'll hold, if you look at it as you turn the arm you'll see it go up or down which will tell you which way to turn when you use it.
I use mine to save my fingers when I trim with the Little Crow Trimmer, it's originally made to be used with a drill press.

[Bazoo]

I have a Lyman universal trimmer and I've learned to tweak the clamping part to get a consistent length. It's not a perfect system. It is fast though, I trim 30-30 every loading cycle.

Yes, they still offer it. I see some on eBay from time to time.

[Bazoo]

I am now the proud owner of this unit. The pictures don't do it justice. It is a stock lyman universal drill press trimmer base but attached to a custom made aluminum (thought it was steel at first) base. Very heavy. I'll clean it up and shelve it for future heavy duty case trimming needs.

Thank you again ohio686!

My Lyman 46th manual shows this tool, and offers it's introduction as 1970 with a $14 price.

I use a shop made one very similar to that one that fits in the vise of the Bridgeport Mill. It has a dead nuts stop for the "drill press " part

that you set pretty close and lock it down, the use the table adjustment to move up .001 increments. The weakest part is thecase holder how accurate it is. That is a very interesting looking part. Thank you for showing this Ohio 686

[Ohio686]

I will look around and see what other odd ball stuff I have

[fatnhappy]

I have the forster unit and it really comes into it's own when you need to remove a substantial amount of material case forming that doesn't warrant a hacksaw. In my case .308 win to .300 savage for example
