Jediael here again. I have been steadily working on additional features for my main mod the Air Tank Magstrike and wanted to share a new tactical component I have been testing out: Magnetic Mounting.
Why don't I just show you first really quick in a video what I'm referring to.
Pretty straightforward but extremely useful for carrying a backup weapon out of the way but still accessible at a moments notice.
I originally did this with a 18 round clip when I was running a stampede/magstrike tactical integration, which you can see here.
In that version, I used 2 sets of 3 neodynimum magnets rated at 6 pound pull strength.
The strength was enough to hold them securely in place yet I could still grab it with no effort at a moments notice like the magstrike in the video above.
You can buy a pack 10 of them for $8 here on amazon if you wish to replicate it somehow.
For my humans vs zombies loadout, it has been extremely useful to use dual magstrikes during missions. My main one is the modded air tank feed one that only needs reloading. I conserve the main tank for times when we are being overrun with only brief chances to reload. When things are slower, I use the unmodded manual gun to conserve my main air supply for my primary. However, it got very tiring to constantly carry both guns after more than 30 minutes so I wanted a way to carry it securely and out of the way.
I decided it would try replicating the magnetic mounting system for the gun, but knew it would require greater strength to handle the forces. I did some running testings with the clip version and found the forces were strong enough to withstand running, tossing and jerking. I calculated the ratio of magnetic power to the weight of the clip and then multiplied that by the weight of the gun to ballpark how much strength I would need.
Clip weight: 8.8 ounces = .55 pounds
6 pounds (magnetic strength) / .55 pounds (clip weight) = 10 pounds magnetic strength/pound of weight carried
Magstrike weight: 2 pounds
Ballpark 10 x 2 = 20 pounds of strength required (minimum)
Now obviously a clip with foam darts is significantly less weight and force exerted by gravity when running, bouncing, jerking around, etc. I decided to be safe I would roughly double the force to account for the greater pulling force of the 2 pound gun when moving around.
I purchased a set of 4 of these 37 pound strength countersunk magnets on ebay for $15.
I used steel putty to permanently affix steel plates to four positions of the magstrike without blocking holes (so I could still open the gun if I wish).
Because of the force of these magnets, I knew epoxy and bolts would be better so the only 'breaking' points would be between the magnets and the steel plate. I used extra putty to put round edged on all sides of the plates in the extremely small chance someone got caught on an edge had I not made them smooth.
I then mounted the magnets to the frame of my carrier to match these locations.
As you can see, it works beautifully and I cant wait to put it in action.
