Hi Y'all,
I got tired of waiting for the vis at my dock to get good enough to do some testing on my Dirty Water Rollergun, so I made a "test tank" instead. I tried to keep the cost down since it is really a means to an end (testing spearguns) rather than the end itself. It's not elegant by any means, but since I was after function, beauty was secondary. The shooting end can be seen from the street, and it's got the neighborhood walkers and security wondering what the hell the crazy guy is up to now. I love it! :laughing3::laughing3:
The tank is made up of 3- 8 foot sections that are 16"high by 16" wide. Those dimensions were chosen so I could get a section out of a 4' x 8' piece of OSB. I had 3 pieces of OSB that I had been kicking around the shop for years, so that's what I used. I used 2 x 4's and 2 x 2's for framing the bottom and sides for support.
I tried waterproofing the OSB with elastomeric paint (used to waterproof stucco) but that didn't seal the holes in the OSB, so I ended up using liquid rubber (used on roofs). That did it. A clear 1/4" piece of lexan and some "cabinet gloves" rounded out the ensemble. I had to use liquid tape to seal the gloves, but they still leak like a sieve, so I'll need to go to plan "B" on the gloves. They work good enough to try the tank, however, so I'll revise the gloves later.
The target is a 16" high x 16" wide x 12" thick foam archery target that is clamped down with bar clamps to keep it from floating (Hey, I said it wasn't elegant!).
So, with the neighbors furiously reviewing the neighborhood covenants, and my beloved wife of 42 years muttering under her breath, I commissioned the test tank today. Here are some pics of the tank. Results of the testing will be posted in the "Dirty Water Rollergun" thread as I go along. If anyone would like more info on how it is made, cost, etc, let me know and I'll be happy to oblige.
I'll try to get some more meaningful shots tomorrow.
