Walt is done and he transferred the business to Bruce Jacobs who is on IA. Bruce currently has a medical situation which may be cleared up soon. I along with others are waiting for him to announce that he is open for business.
 
From my own experience, spot to be soldered, rough it up good. Then, Rough it up like you hadn't done any...
Probably better to use a softer solder, NOT silver bearing solder. Because the solder will need to be slightly flexible. I always used acid flux. But, I think it wouldn't hurt to use some denatured alcohol. Or, better yet, Acetone. Inside and out.

I’ve actually thought about buying a small brake and start building tanks, I’ve built some with hand benders using brass sheet…

Anyone know or have a lead on what type of sheet metal is used to make the metal tanks ? Is it just plain coated steel or is it stainless sheet ?

I just used .010" thick cheap chinese staino,off fleabay lol,came in a small roll and I flattened it out,solders well.
I did my edge bends in a vice using alum angle as job guards,bends pretty easy,,added some criss x creases on top and bottom plates to stiffen them.Also drill the fuel tube holes a fair bit undersize,then push/bash a suitable nail/tapered punch through to size,so it gives a rolled edge hole,for better solder purchase.I also added 2 horizontal internal baffles in the pickup area to about 1/2 tank lenght.with a small gap on right side of tank side and vent gaps here and there.Worked well in a hydro

Hope you've been doing well Frank,,cheers

BRASS???.....Hell, why not just make them out of cast iron?....😂😂😂😂

Tin or stainless, I would think. We used to make our own for 1/2 A control line planes back in the 60's, and I thought it was tin....Dad brought some small sheets home from the shop at Buick for me, 'bout all I remember....lil' 2-3 oz tanks is all those Cox Thimble Drone TD 049 and 051's needed.

Well, it was shim stock… flat sheets, and it was a twin .90 eagle, so weight wasn’t “that” critical..
never weighed them, but I’ll bet they aren’t too far off from steel tanks..
besides… not sure you can find anyone that builds tanks with a “pony” tank inside of them.. there are a few trick things done to them..

I actually still have that old eagle and the tanks,,, maybe I should weigh them against another set of tin tanks I have..
Might be interesting to see how much different they weigh ..

Weight's always critical when dealing with anything 'racing'. 😉
