This is why ideas rarely get tested around my place. I didn't have a piece of 18" angle iron within eyesight, so... I called an engineering consulting firm and arranged a conference call with 3 engineers and a material specialist to decide whether this would work :
Calibers, ranges, projectile composition and likely common highest velocity at point of impact were discussed. Very tiring dealing with these types. I asked if they could complete the conference call without me, as I felt the need to puff a cigar for a few minutes. They called me back with the go-ahead an hour and a half later. Sweet.
The more attention to detail oriented types may notice the odd look of the two nuts, how the top is somehow gone. That's because in the pic that I snapped they and the lower threaded rod were too far from the upper threaded rod, so digital magic saved me from having to walk over and set the stage again, so to speak. Both of Steve's nuts are there, and to all my powers of observation appear to be complete and functional. Mark the center and then a convenient spacing for the threaded rods. The photos include a lot of parallax. Deal with it like I did.
I chose to space the rods at 8", assuming that at some point the 2x4 will have to be replaced even with a prophylactic like this construction. It is easier to mark a spot and then measure down an easy number like 8", rather than try to transfer an odd number like 7.493723". Then help the steel become one with itself.
I can take the abuse. Go ahead and talk about my welding skills.
Clean it up just enough for paint to stick.
A part of this experiment, BTW. I neglected to mention a LOT of things in this, but this one is kind of important I think. One of those threaded rods is joined in holy matrimony with the piece of angle iron, and one is still an independent fellow, apparently afraid of serious life-long commitment.
The nut is welded in there, and the rod is able to be threaded on and off, in and out. I preferred the idea of separate rods, but I am not convinced that the separate rod won't work itself loose during a day at the range... Or get lost since it is separate. The prophylactic would be a smaller package if both rods were loose... and loose shafts allow for easier alignment in tight or misaligned holes. I gathered the materials and built a 1st rate paint booth for this, complete with natural ventilation.
Then I gave several light coats of a high end polymer sealant and then the same, over several hours, maybe days with a top notch paint. I sanded in successive steps with ever finer sandpaper, then Flitzed it when I got to 1200 grit.
Or maybe I just glommed that stuff on there in about 2 minutes, I don't recall.
For those who want extry ammonishun to enjoy jumping in like sharks on a crippled tuna, here you go.

Boy that WGO Site Admin job plays hell with your hair.
The hair was gone long before WaGuns came along . . . .

Agreed. My biggest concern is that it will limit the motion of the plate; it swings back a few inches, but then hits the 2x4.
All of my builds have been free swinging (commando style?) I have seen that spring doohickey a few times, not sure that I like it. For one thing, it will dampen the Liberty Bell type of tone a bit. If I get time in the shop before the trip up there I will bring another type for you place next to that cityboy-bought fancy one and compare the action. I don't keep a supply of AR500 plate here though, so tone won't be the same, all other things being equal anyway. Yours is hard and mine is soft.

lets sight in my 308
There is not much defense against intentional destruction. Keep Ops away. The one I whupped together yesterday is only ~10 inches long, which to me seems HUUUUUGE, but might seem normal to some of you beefcakes. 10" will only be of interest to those shooters who shoot low no more than 8" or so - but with this design, even a direct center shot that penetrates the point of the angle and completely destroys the section of 2x4 behind it will not cause it to topple over unless the shot hits close enough to one of the bolts. Don't tell Ops where the bolts are.

If someone can hit a chronograph. they definitely are going to hit a 2x4
The chronograph is only a few feet away... This 2x4 is 100-200 yards away. I'm betting on the 2x4 to survive more direct hits.

Well, Mike, now we know your daughter can weld circles around her daddy.
One of them nut welds looks like an epileptic ran the bead while being tasered.
Steve - you still getting royalties from the Mighty Bullet blender company ?

Hey wait a minute - if you're going to drill the 2x4 for those bolts, isn't that like shooting holes in it? Or is that OK, as long as you put armor over your own holes? :)
Nice idea, I like it, and the JC target. I need to get a few like that, that are easily set up and taken down.
One of my shooting buddies has a 10" (I think) gong hanging from two chains on an overhead crossbar. It works pretty well, swinging back and forth, until we shoot it with the 35 Whelen. That reliably throws the gong all the way through a full loop, wrapping the chain around the crossbar and throwing the whole contraption on the ground. Pretty funny the first few times, until you have to keep resetting it.
