BTW Rat makes an excellant wrench & barrel vice.
Fair price and in a couple of days it is on your doorstep. No muss no fuss.
I can and will make my own tools, but sometimes it's just easier & faster to just buy the thing.

I built my wrench from their drawing (gunthings.com). Worked for my build.

Phillip -

Here are some images of one of my older wrench designs. It shows how it fits on an IMBEL barrel stub. You will note that the fit is not perfect, because the design is a compromise between various barrel stubs (IMBEL, G-1) that I had laying around, and various receivers that I had to examine (IMBEL, Coonan, Entreprise Type 1 & Type 3.)

In this first image, I marked in green the areas on a receiver where it is safe to clamp on with a receiver wrench:

This second image indicates in red the areas of a receiver that are more fragile, where you want to avoid putting any load, notably the gas tube nut area and the charging handle:

If you plan on doing a build with only one receiver type, just trace the outline of the receiver front and use that as a guide. The outline does not have to fit the reciever perfectly, because the wrench in reality will only make contact in small areas. You can see this if you examine the stub on your kit. One can usually see the marks from the original assembly - expecially on the IMBELs. I don't know what material you plan to use, so work accordingly with how you cut out the receiver halves. I split mine in the horizontal plane. This is typical. I use two each 5/16-inch cap screws for clamping, but the classic Casey Elliot wrenches (which have not been made for some 5 or so years now) use larger 3/8 inch cap screws. I don't think anyone has broken any of the 5/16 cap screws yet. I also use my wrench to remove stubs, with my barrel vise, a 3/4 drive slide (breaker) bar, and a 4-foot pipe. I do have the vise bolted to a very heavy workbench, thank goodness.

I use 1/2-inch thick structural-grade steel plate. This is about the thickest you want to go, which can be seen be examining the front of your receiver. Aluminum will also work, but is more fragile, of course. If you use aluminum, just use 6061-T6 - the workhorse aluminum alloy. Folks have made good wrenches from aluminum.

Now, if you build an inch rifle, check the receiver closely, because on my inch receivers I had to modify a wrench to fit properly because of a small taper ono the underside. Below is the inch mod for my wrench (top) and the classic Casey Elliot wrench (bottom.) A few minute with a Dremel or file is all it takes.

Keep us posted on how it goes. (Yeah, I know, bad pun. :D )

As usual great info.FYI,I print all the info and put in a file or save it on my computer for build time ref.Im currently scrounging metal for my vise and wrench.Ill post pics when I get to that point.From what I hear theres a wait on rcvrs at DSA so Ill have some time to build my tools.
