This was my first attempt at building a fiberglass [Proton Pack](https://www.gbfans.com/wiki/equipment/proton-pack). The original wooden buck was built in two parts; christphern of the Tennessee Ghostbusters built the upper assembly, while I built the lower half and gun box. Our plan was to cast fiberglass shells for our respective groups. Easier said than done, right? ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_01.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_02.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_03.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_04.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_05.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_06.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_07.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_09.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_08.jpg) After the buck was painted and ready to go, I made a silicone mold using Smooth-on Rebound 25 and then did the two-part fiberglass mother mold. ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_10.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_11.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_12.jpg) Freeing the buck from the mold was not fun (I was told that a mold release wasn’t necessary for Rebound 25, but should have used it anyway). The EDA and [N-Filter](https://www.gbfans.com/wiki/equipment/proton-pack/n-filter) were destroyed in the process. ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_13.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_14.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_15.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_16.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_17.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_18.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_20.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_19.jpg) Being my first time working with silicone and fiberglass, I made a numerous mistakes that resulted in two slightly warped, mediocre shells that required a lot of clean-up. Of course, I never expected perfection, but have learned a great deal about casting and mold-making. Our plan is to recast the buck (without the N-filter attached) and do it correctly. Some things for next time: 1. Use a mold-release agent. 2. Have the N-Filter be a separate add-on piece and not part of the mold. 3. Use the method of pouring the silicone into a cavity (filled with clay) and leaving holes in the mother mold for “keys”. The part that I’m still struggling with is laying the fiberglass inside the mold. I’ve done it twice, and can make it sturdy, but it’s far too thick around the [Cyclotron](https://www.gbfans.com/wiki/equipment/proton-pack/cyclotron) and [Power Cell](https://www.gbfans.com/wiki/equipment/proton-pack/power-cell) windows. On the second cast, I tried doing a single layer of fiberglass mesh on those areas, but the resin still gathered at the bottom. Overall, this has been a fun, enlightening, and nightmarish experience. While the final product is pretty bad, it’s far from unusable.

Thanks for the compliments, everyone! I did some work on the thrower over the past few days. It’s far from complete, but it’s starting to vaguely resemble a Neutrona Wand. Not looking forward to building the [gun track](https://www.gbfans.com/wiki/equipment/proton-pack/gun-track), though… ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_DSC\_3146.jpg) ![image]([http://www.gbfans.com/images/pb/wraithofmusic/GB2](http://www.gbfans.com/images/pb/wraithofmusic/GB2) Belt\_DSC\_3147.jpg) ---

Good job for your first try. Actually looks a bit better than my first attempt. Here are few tips if you ever try for a second mold. -The mold you made looks pretty much like a glove to the pack. You want to use the tickvex II thickening agent to make the rubber very thick and build up surfaces. This reduces the number of pinch points and allows some flexibility between the mother shell and the casting. -It is possible to cast with the [N-filter](https://www.gbfans.com/wiki/equipment/proton-pack/n-filter) (the pringle can) on the [cyclotron](https://www.gbfans.com/wiki/equipment/proton-pack/cyclotron). When you make your mother mold, have the seam go over the n filter. This is how I did my cyclotron mold and it worked very well. -The best teqnique I found for laying the resing and class is paint on two layers of gel coat which is half resin and half microbulb filler. Then when you add your cloth, paint a thin layer of resin with a brush, lay the fabric down, and pad the fabrin with the resin filled brush. If resin starts to pool in the mold, use the brush to dip in and use that resin to coat the spot for the next piece. I also sugest putting fiberglass mat anywhere on the pack that will become load bearing, especially near the gun mount. Hope that helps. ---

I was part of this entire process (considering it was being built both in my kitchen and on my back porch), and I’m glad to see the pictures getting some views. It was an insane project for someone like me who is used to sewing… a type of crafting where you see results almost immediately. What Demon forgot to say was that the police showed up at our house after two days of fiberglassing on the porch. Apparently, a neighbor had reported a smell they thought was a meth lab emanating from our porch. The cop thought it was all pretty funny when he saw what we were ACTUALLY working on. ---

Back when Dave and I use to work on the porches of our apartment complex, we would be out there with resperators, gloves, glasses, and canisters of resin and white microbulb filler. I still can’t believe nobody ever called about a meth lab. 😊 ---

It’s finally done. Despite some glaring flaws, it somewhat resembles a [Proton Pack](https://www.gbfans.com/wiki/equipment/proton-pack)… ![image](https://discdn.gbfans.com/original/3X/9/e/9e739d7c0fa21936472cbd070b36eb04e9494128.jpeg) ![image](https://discdn.gbfans.com/original/3X/c/2/c29d15f9047f7020212bdc70f39e1a2ecadd9845.jpeg) ![image](https://discdn.gbfans.com/original/3X/f/b/fbbfe7327888a0cefb3496a7ed5808ec716e9655.jpeg) ![image](https://discdn.gbfans.com/original/3X/6/c/6c3ba7dd96e7b0a75153c047369971d77b8cfe38.jpeg) The next project will be the gun/pack lighting! ---

The best way it worked out for me is to try and kill all of the detail on the inside before you even put glass anywhere near it. Now I do 2 layers of Gelcoat and a thickened ‘toothpaste’ layer of resin to fill in all the corners before I even touch it with glass. I think the norm over in the states is the woven fabric, but that’s a little less common here. I heard that stuff is easier to work with than mat. Lawrence ---

Yes, you want to rip the mat into pieces about the size of a half of a dollar bill or smaller.
