I am looking for a picture of corbins lead wire extruder. Or maybe someone could tell me if its possbile to make it work with a standard 20ton H-frame press? I really want to extrude my own wire but don't have the means to build and extruder right now. I figure I wouldn't mind buying it from corbin, if I could make it work. Any ideas?
Thanks

Look in the thread in this section "homemade lead wire" for the pics member "shooterg" posted for me of the die I made. I use it in a 20 ton press and it squirts wire like toothpaste.
A friend showed me pics or a die from Corbin and I enlarged it to handle 1''x6'' slugs.

I made my lead wire extruder using a log splitter.
I used a 4" bore cylinder and cut the ram off square and replaced the wedge with a die the ram fits tight, that handles a 5# lead ingot.
It's important that the extruder hole is counter bored with a slightly larger hole so there is less friction and the wire will flow much easer.
This thing will make a .400 wire with ease.

Here is a few pics of my Corbin Wire Extrusion Die. It’s nothing fancy, just a cylinder, threaded on the exterior with a honed bore.

OAL is approx. 6 Ύ”, OD is 1 5/8” and the thread is 1 ½” NF. The interior bore on this one measures 0.820”, I’m assuming the interior was drill and reamed 13/16” and then honed to 0.820” after heat-treating. The ram/piston is not shown in the pics, it’s just a straight shaft, hardened, and measures 0.818” in diameter.

The individual wire dies themselves come in various diameters, to suit your needs and would not be hard to make if you have access to some machine shop equipment. The ones pictured measure 0.215”, 0.248”, 0.282”, 0.298”, 0.310”, 0.348” and 0.365”.

The lead billet is drop in from the top, I use a Ύ” OD x 4” billet. Once the billet has been inserted into the main die, the wire size die is dropped in and then the retaining “what-cha-ma-call-it” is screwed in to hold everything in place. When you drop in another billet, the lead will swage itself to the remaining lead left, thus giving you one continuous piece of wire.

If you can get yourself a piece of 2” Heavy Wall DOM tubing (drawn over mandrel/seamless tubing) with a 1” bore, you could make your self one heck of a good wire extrusion die. And with a 20 ton press, you’ll have lots of “HP” to extrude all the wire you want.

I hope this helps.
