For those that are welding/welder challenged, I'm still working on my DIY + Parts version that is portable via a canvas bag, fits easily in my car (VW Golf) and is assembled at the range. Mainly the rack is for 22LR at 50 & 100 yards, but with it being AR500 steel, it could take most centerfire hits too - with 22LR. it'll likely outlast me.
I know that I could have just bought a KLY rack/stand - and frankly I looked at many of them on-line. The bad part for me is most of them are large when fully assembled and have long legs, parts, beams, etc. That is exactly what I wasn't looking for. I wanted something small, easily transported, came apart easily and could fit in a ~24-30" canvas bag - all with readily replaceable parts. Know that if I was building this for my own land/personal target range, I may not have built mine this way...
That said, here's how I built mine. I ordered 16x 1" wide x 1/2" thick and 4x 1" wide x 1/4" thick AR500 gong targets from shootingtargets7.com. Bought a 36" threaded stainless rod (I'll cut to size after I receive the stand connectors), 4x 24" long by 1/2" thick pieces of rebar, a bag of 25x 2" wide galvanized washers (with a 1/2" hole in them) and a bag of 25x galvanized nuts for the 1/2" stainless rod - all from Home Depot. Lastly, I purchased the target stand ends from The Last Stand and should receive them next week.
I initially tried to put something together with turnbuckles, but couldn't find exactly what I wanted at Ace, Lowes or Home Depot. I don't really have access to a welder or I'd have welded a washer to one end of each rebar section for the threaded section - then to be secured by a couple of nuts. That also meant that I'd have needed sort of a folding lock bar or a wedged shaped gusset to keep the rebar spread apart and stable, and maybe a washer on the end of the rebar for ground stakes. All in all, I felt that with the welding I would be creating just another science project that I didn't need - without a whole bunch of benefit or added performance - just more $hit to break. So, in the end - at least IMHO - it was worth it to just buy the stand ends from LastStands.com and call it a day. We'll see how they perform and hold up over time.
FWIW, I used Rustoleum white matte primer after cleaning both the targets and rebar. That's what I've been using for my other steel as it's cheap and dries really fast. Also, I "could" have not used the washers and used only the nuts, but with the washers, each target/group seems to swing a bit easier with the washers than without.
Oh and one more thing. I didn't feel the need to weld, install a bolt, glue/epoxy, etc the individual swingers in each target group. If one of the swingers swings from a hit, I think I'll be able to see/hear it even at 200+ yards with the 22LR - we'll see after I get the last of the parts and take it to the range.
