Plywood Tank 250gallon

Postby Coln » Sun Mar 15, 2009 4:05 pm

Hi started this tank a few weeks ago to make this existing tank bigger but have been
reading TFG, 13lazd and 98dak83cam for a while which kinda made my mind up to
go for this tank.
I'm making a 250gallon plywood tank which will be in the garage but viewed from the
lounge. I'm posting it on a uk forum as well hope thats cool, share everything yeah

Cool! How will you be sealing the plywood?

Good luck with your build!

Did you buy it yet? You may want to check out Progressive Epoxies. The web site is a bit confusing, but I think you get as good as or better product for a lot less money. This is what I will be using.

Also look at U.S. composites epoxy it was very well priced and works very good. I see you bolted the corners together but it looks like that is it. Are you planning on going back and lag bolting into each of the boards or are they already it is hard to tell in the picture? not sure but if not Just those screws will not hold all that pressure. I would also recommend putting braces on the top and bottom of each board. Can't be too safe. other than that is it lookin' good :thumb: . Good luck man it is an awesome project and well worth the time.

Already got the epoxy, am using 12mm/ 1/2" threaded rod to bolt all the panels together about
12" centres with 'lock' nuts

threaded rod is a pain in the a** to use. I tryed that originally then switched over to the lag bolts. Here is what I used to bolt down my tank, you just need to pre-drill as to not split the wood.

These are much easier to work with.

Think I need the strength of the 12mm bolts and cause the tank will be on two concrete block
walls I can get below to tighten the nuts. Plywood is 18mm and framing is 100mm x 50mm and
glued and screwed and is really solid

are you going to just silicone the seams together or go back and fiberglass them together?

Going to silicon it all together, the silicon will just be a seal cos the bolts will hold the tank
together plus if it does have to come apart for any reason would be a bit easier

Looking good!

Did you use fiberglass cloth with the resin? If so, what weight cloth did you use? Did you do mulitple layers?

Thanks!
