Well the plinker is finally finished. The target arms have been lightened, locating bushings were made and welded in place and paint applied. Now its scheduled to be tested on Saturday with the SR22 and Cooey.

I plan on posting a video of its operation if it works as designed. Otherwise I will make modification and try again.
 
Very nice but what does it weigh? I'm also thinking those arms might be a little heavy to flip all the way over from anything over 15-20 yds and maybe not even then. Don't get me wrong I really like the idea it just looks a little heavy compared to my commercially made flipping targets

Just got back from the range and will post a report. The short story is that I need a counterbalance or lighter targets.

I will show what it took to flip the targets.:eek:
 
Looks real good. I can't wait to see the video. I'm surprised your .22 wouldn't flip those targets.

I have a stand I made with similar pendulum style targets. The arms are 1/4" x 1" flat stock with various size circles that are 1/4" thick. When hit the targets spin around prbably 15 to 20 times before coming to rest.
 
Well the wife and I went to the range today and tested the plinker. At just under 60 lbs. it was easily walked down range and in position. I tried at 50 yards and 25 yards to get the arms to swing around. Using CCI Blazers, Stingers, Mini-Mags and Winchester 555 bulk. Nothing would flip the arms.

I was surprised. The targets are 3" x 3" x 1/4" welded to 1-1/4" x1/4" x 6" arms. All is cold rolled steel.

Here are the after pictures.

Targets hit dozens of times with no damage to the plates other than paint removal:

Shrapnel appears to have removed paint on all adjacent exposed sides:

My next trial was to see what would make this target swing. I moved it out to 75 yards and one shot of 7.65 x 39 FMJ from my SKS was enough to get the target swinging, but only one. The round went clean through and it swung around and landed on the reset T bar:

I will make modifications by adding counter weights at the top or lightening the swing arms. It will work next time.
 
It's amazing how much it takes to get swinging targets to go around. I guess a .22 doesn't have the hitting power most people (including me) would think they do.

I have a commercial one from cabellas and a rifle will spin them out past 60 yards, but my S&W 22A won't flip them out past about 15 yards.

I was going to tell you that paint only lasts one trip to the range as the sharpnel effectively 'lead blasts' everything. But I would have painted it too...a guy has to have a little pride when he builds the mother of all resetting targets. Keep modding it, you'll make it work I'm sure.

I was truly surprised they would not swing around more than . The video that I posted was at 25 yards. They didn't seem to move any more or less at 50 yards for some reason.

With regard to the paint, I will still repaint the targets blaze orange for my next trial just so they stand out.
 
So what do I win for most accurate guesstimate?? I would put counterweight targets on the top so you can spin them either way. Just make the top ones a bit smaller or make round ones the same size as the square ones. Anyway you do it I'm sure it will be fun. I just noticed you had them resettable not spinners:redface:, I can't for the moment see how to do that with the heavy targets but I'll think on it.

I will add a weight at the top of the arm and have it so that a slight push will cause the target to spin over. It should be easy. I was going to add the weights to a few arms before going to the range just as an experiment, but I foolishly figured it wasn't necessary.:(

Another method would be to move the fulcrum closer to the target. That is to much effort and I like the postion it is in now. I am also going to add a few targets that swing from side to side on the uprights just below the swinging target and above the paper targets.
 
i think 3/16 steel and smaller dimensions on the arms and the mounting/pivot point moved closer to the target also drilling lightening holes in the arms. oh and counter weight i have one from crappy tire it is 4 small and 1 large reset.

I honestly don't think that will work as any weight you add will either cause the targets to rotate (not hang vertically) or add so much mass that you won't move them at all. You need way lighter arms for a resettable or changeing it to a spinner type target are your choices IMO.

I put a fire bell horizontaly behind mine. Then a 1" round target welded to a few links of chain hanging infront of it. Its been working for more then a year. Still fun.
 
Very nice work building that, by the way it reacts .38 special or 9mm might be perfect. .22 wmr may work but would probably dent the plates.
