I will say this so far... service is by far outstanding... i have tracking info already on the tank i ordered.. i will post a pic of the tank in the boat when i get it.
I've made quite a few .21 JAE tanks this size and seems to be pretty popular. It holds apprx. 8.8oz and has an internal hopper tank.
L- 4 3/4" x W 2 3/8" x H 1 7/16"
Just FYI, I modified my welding tip and have been practicing new techniques and from now on all my tanks will be seam welded and then each seam will be filled will HDPE welding rod. I know it's not as clean looking as tthe tanks with just the seam welded, but let me tell you it's alot stronger and at the end of the day that's what matters. To date, with out a doubt this is my strongest tank out of the lightweight 1/16" material.
