I promise Jim I did listen and I understand I am taking the long way around the pond, I just don't have a choice budget wise. I am I think and hope taking the right steps for the second best choice though.
First is that I am going to be using a material that will rust and that the activator makes it very difficult to find a coating that will not breakdown.
After doing some research and watching some very interesting results I believe I may have found a paint on rust prevention system from por 15. This material has stood up against both brake fluid and paint stripper according to this You Tube video (Yeah we all believe what we see on the internet) a neat little thing about this manufacture is they offer a sample kit for about 20 bucks that you can test out por15.com/SUPER-STARTER-KIT_p_11.html
More details about it here por15.com/POR-15supregsup-Rust-Preventive-Coating_p_8.html
I have seen what brake fluid can do to paint so if this stuff can stand up to being soaked in it and paint stripper I think it will stand up to watered down activator
I got a really good deal on 3 sheets of 4x8 16 gauge steel and I am using a 14 gauge plate on the bottom, 2 sticks of 24 feet 1" square tubing and 24 feet of 1 1/2 inch angle iron $250.00
My build dims are 4Wx7Lx3D With an outside Skimmer tank I will have a 7 foot long work area
The tank itself will be fully framed with angle iron and bottom and side braced with tubing. I'm also going to use my excess to weld flex bands along the bottom to strengthen the bottom sheet along with building my skim tank
For Heating I am going to try something that I mentioned in another post and that is the self circulation engine block heater from Kats,
Tools being used,
14 gauge electric sheet metal shears https://harborfreight.com/14-gauge-4-amp-heavy-duty-metal-shears-68199.html
For Harbor Freight tools this little jewel is one crazy good work horse so far it cuts the 16 gauge steal cleanly and is easy to follow a line with. The trick is to remember it takes close to a 1/4 inch off in material and keep your excess piece from flexing so it doesn't bind anything up
14 Inch cut off saw
Sheet Rock Square
I am having the tank welded by someone else I don't have the skill to make those kinds of welds
So far in material I have $300 This is in steel alone it does not include plumbing, dams, pump or heater.
I am at the point right now of trying to decide on my width of the tank, We are talking about the difference of 200 gallons of water and 1600 pounds of weight
The balance point on this though is factory cuts vs hand cuts, this in itself can make the difference in the difficulty of the welds and structural strength.
4 wheelers, ATVs and custom pickup shops are big in this area and so I want to leave myself an opening to be able to do them if so called for, even though most film is only 3 feet I wonder if that extra 1 foot in width would give some needed room for those kind of dips?
What's your feelings?
