Finally got around to building these-

Almost two years ago there was a topic started on someone inquiring about home made, DIY, pellet traps thst one could easily muster up parts and have somewhat of a safe projectile catcher that a target could be attached to. Rubber mulch was the media that was highly recommended on this topic, and sure enough different members started posting pics of their home brew set ups. 


All the pics sparked an idea. Now mind you, I already own two pellet traps, steel structure snd backing media is the tried and true duct seal, but after a couple of years using these 10” x 10” steel boxes filled with 7 lbs of duct seal, the idea of the lighter media in rubber mulch appealed to me. Plus, one of my goals is to one day try my hand at one of(or both) of the annual benchrest competitions and I already know that’s a lot of practicing. Out to a 100 yards, I couldn’t see myself hauling around these heavy pellet traps, and say, I wanted to shoot closer the idea of moving the heavy trap closer or farther just put me off. Then, the worst part comes at the end of the shooting session, all the gear including those heavy steel boxes a 100 yards away would have to be put away. 


so in my mind, it had to either be easily portable, or be able to withstand the weather and just be left outside. These two pluses alone means I’ll set up to shoot more often, as it would be less work to set up and clean up.

So I posted this cartoon plan of mine on that very thread, the DIY one, and said one day I’m going to build these-

I have had all the parts to make these for awhile, minus the rubber mulch. My goal was to build 5 of these so I could set these up at 12-18” off the ground, in 10 yard increments, starting from 60 yards all the way to 100. 


So the first prototype was built today-
 
Doing a test fit onto the 5 gal bucket-

had to take my Hamlet hand tongs to curve out the side flanges for a better fit up

you can see in the yellow clouded area some of the spot welds popped loose, but no biggie I’m going to solder up all the seams with some good old 50/50 for the strength it’ll add.

I then clamped it onto the bucket once I saw the fit up was good, then attached the saddle tap onto the bucket temporarily with sheet metal self tappers to not only hold it in place, but also the holes from the screws will act as pre drilled points that I’m going to enlarge for the 1/4-20 bolts I’ll be using 
 
Now onto marking out the opening for cut out- after marking the opening I opened up the corners with a uni- bit/step bit for my jig saw blade to enter into to start the cuts-

while I had the step bit out I drilled out three weep holes so any irrigation or rain water that gets into these traps if left out the water will drain out.



Then comes the application of the 12” wide by 12 1/2” long galvanized wire mesh. This material isn’t something you find where the windows are at your local Home Depot, btw, but instead is found by the gutter and roofing section in the building supply areas. It’s use is for soffit vents, louver vents, etc. Typically in my trade it’s called Bird Screen.

The screen is designed to be replaceable, as it’s going to get shot up. It’s main purpose is to keep the rubber mulch in place, 5” behind the target. So duct tape is the attachment product of choice, as the mulch alone will hold it in place securely-

Almost done!!

Now comes the step of final mounting of the sheet metal fitting.

BTW, this fitting, correct terminology. Is a square(or rectangular) on round saddle tap. It’s used a lot in my trade typically on architectural exposed round ducts, to be able to mount a supply or return air register on. Just an FYI-

all bolted up, now let’s see what it looks like with a used target on a cardboard backer in which I will use magnetized clips to attach to the 1” flange out of the saddle tap-

as it turned out, when measuring this up when I was planning it all, I picked an inside dimension of 10” x 10” as that has worked well for me with my steel box traps. That dimension works well with the packets of Caldwell shoot n see targets I get, and any other target slightly wider I can use standard earth magnets to hold the targets in place without a cardboard backer. 


I did not dump the mulch in yet as I need to disassemble this prototype to solder the seams, then I’ll etch it so I can throw some paint on the sheet metal and while I’m at it, dust the buckets with some green/tan/and black paint so my wife doesn’t complain about these bucket set ups spread around my parcel, ha ha! 


material cost wise since the buckets are just empty chlorine tablets buckets I’ve been saving up, the screen, nuts, bolts, washers, and a $6 bag of rubber mulch(one bag will easily and perfectly fill this 5 gallon bucket to the cover, btw) I’ve got about $30 into it. The hardest part is the saddle tap. I’m retired now so I have no access to a sheet metal shop. I could make these at home but the bends(we call them brakes)won’t be a crisp clean 90 degree but instead rounded. If I had access to a shop I could hand build probably a dozen or more in a day. If I had the guy running the plasma burn out the pieces it’s just a matter of forming them and spot welding so yes, about 25 a day I could put together. 


Hope you enjoyed my thread on my home brew indoor/outdoor rubber mulch trap. I’m just glad it’s finally being built. All the parts have been in the back of my pickup truck in the garage for well over a year now, lol!

Yeah that is pretty nifty.

I have myself contemplated what i / we could do in regard to capturing lead at my friends place, instead of just leaving that to the earth berm.

Something along these lines would however be nice on the longer ranges as it is sort of mobile and i will be the only one shooting there ( well i think at least )

Could just place it in the ATV trailer, use that to drive to its location and then pling - pling,,,,, or probably more a muffled thud - thud in this case.
