Lightbulb Stefinstein chop shop 80rd hopper

Well this is long overdue, I've been promising people for a while now on a how to for my hopper. Awesome profile on these things, it's about as tall as an app 50rd and feeds very well. I put it together with hot glue seems to hold up well against the shock on being hit at 300fps. I've tried everything from super glue to welding the plastic together. JB weld doesn't set up fast enough all though I'm sure a coat of it afterwards could get a nice finished look after its together. Anyway without further adoo!







And just a sketch on the measurements. All measurements are straight distances done with either a caliper or a compass (NOT along the arc of the hopper with a ruler or tape). The hardest part of the cutting is getting a straight cut from point to point along the curves of the hopper (I suggest using a band saw on each half of the shell)



The rest of the pictures show how the measurements are made.









You will want to cut the top and bottom pieces first, and then use the scrap that is left over to make two triangle pieces to fill the back. If you would like to be able to clamshell the hopper after building it (for cleaning) then you will NOT want to glue the middle seams together. Hope this inspires some creativity from the mcb community, enjoy!

Ask your local fields for their broken ones, saves money and guilt.

Well I tried the jb weld and it doesn't hold to the plastic, it just peels off I will try scuff it a good deal and do another round, if that doesn't work I'll move on to some bondo, paint, then clear coat or epoxy. Good idea overlord, I think I'll do a one piece seamless look, covering all the holes as well. I was originally stuck on the idea of clam shelling it for cleaning ability, but it's small enough I can reach the front with my hand. I will post more pics as it progresses

Yes it's finally here! Build your own, get inspired. My inspiration was from a proto primo loader a friend of mine chopped down. I believe he also covered it in a thin layer of foam (for bounce factor) then taped it up with camouflage tape, it looks pretty slick. He may even post a pic of it up here if we are lucky.
