Re: Foam War Machine and Gatling Gun with Stronger Mount and other WM weaponry!
As promised here is a rough outline of the gatling gun mount issue as I see it and a possible solution.

The problem is that even a light foam gun mounted on the shoulder of a foam suit causes compression and bending issues, due to weight and leverage as the gun is long and mounted on an arm which makes it longer. Thus you get even more leverage forced onto an externally mounted gatling gun with a small mount point. This is as you can imagine is not to good for the suit and could mean alot of fuss when you are trying to wear your armor to a party or a Con :angry
I have seen quite a few really good solutions, but most involve building up more foam/glue and tape in an effort to make a strong base to mount the armature and gun onto.
Even on a fiberglass/plastic suit the weight of the gun on the suit could crack the glass, especially if you want a heavier working gun as I intend to build!:cool
So I want to build an understructure of aluminum and PVC that will be worn under the armor with only a single mount point protruding through the armor at the point in the upper back plate that the gatling gun armature is mounted too. Like the movie armor
As a possible bonus, an internal harness could even be fiberglassed into the back piece so that it is all one unit that rides on the shoulders and allows for solid mounting points for straps and clips to hold up cod pieces, thighs/upper arms ect.
I drew up a rough picture on a napkin (Hospital stationary lol) and started to look up things off the shelf I could modify. Not much luck there...The last post had the ALICE army back pack frame that I thought was closest to a solution and I ruled it out due to size and thickness due to the stapping and supports. Even adjusted as tight as it would go it still stuck out too far and hung too low on the back to be of use without heavy mods. :eek
I had the drawn up pic with me and the Army surplus store guy said it looked like a snare drum rack. Here is one with some notes.
A snare drum mount is worn in front with the drum at low hip level hence the design.
I opted out on this idea as enough of the suit is costing me money and lots of it! I would rather have that money to buy parts I need from the junkyard like a helmet or Bigturcs new bolt set for all the joints...(check it out in the junkyard!) Plus I would need to modify the snare holder, so why should I spend 129$ plus on something not quite right. :confused
This next pix is my roughed out ideas that I had...
I wanted a fixed back structure that allowed the gun mount to pivot freely to the left and right yet was rigid enough to hold even my soon to be modied Nerf Punisher Gatling gun which weighs a ton.
Sorry this isnt in CAD! :lol Please pardon the poor draftmanship..:cry
I bought 2 inch by 1/4 in aluminum bar stock for 10 $ at SkyCraft surplus, some metal screw and nuts from Home Depot for 3$ and the PVC came from my scrap box so zero$
The idea is to make the shoulder bends and join them with a bridge piece that will run across the shoulder blades. I will pad the shoulder bends with foam of which there is no shortage around my house right now
The main holder will be a U bend in which I plan to drill 1-1 3/4 holes to run the PVC though. The length of these ears will need to be determined by body thickness and armor position.
The cool easy and cheap part of this build is that the PVC couplers will not only keep the pipe in place but allow it to pivot freely right and left!
The lengths of all parts are yet to be determined as I have to finish the back piece first. I believe that the PVC pipe lengths will be easy to modify to put the pipe out of the back piece in the right spot and the length of the pipe can be adjusted (cut) to fit any mounting choice. PVC can also be painted to match the armor.
I will have to explore fixing the armature to the PVC pipe, this shouldn't be an issue, but I was thinking a block of wood inside the end of the armature with an angled hole drilled in it to accept the PVC pipe and a set screw so it can be removed for storing the suit for transport. Could also just glass the whole armature and fill the ends with 320 or 321 then drill a hole and go back to the same principles as with the wood.. I am still waiting on building the gun and arm before I solidify that set o plans...
I made a mini model just to get a better visual take on it.
The popsickle sticks represent the aluminum and the green straw the pvc. (Check out my Youtube video on "The art of Popsickle bending!" ) Just kidding! :wacko
The black tape represents the PVC couplers . The ear lengths on this were arbitrary and picked so taking a picture was easier. I believe that the PVC pipe support ears will only be a few inches long rather than the scale 2--3 feet long LOL!
You can see the "couplers" would cradle the aluminum ears but still allow the PVC pipe to pivot freely. If you really wanted to kill it you could put a track inside made out of C bend aluminum and make it so the gun can pivot and be moved right shoulder to left and back. *sigh* so many ideas so little time.
I will take pictures as the build progresses! I am super excited about this and hope the idea has merit for other builders...
