Oops, yup it's 1/2"

Ok well it's possible that the tube is 1/8" thick but for piec of mind I would see if you could get 4 more vertical tubes put in so that there is one every 2 FEET. :biggrin:

Yeah, I would feel more comfortable with that. Really kicking myself for not getting some input before I had this thing built :sad: Now I'll have to see if I can find a welder near by to fix this thing up for me. Thanks for your help Grizz!!!

humm dawn a welder who frequents edmonton alot and likes frags....gee could be tuff hehe:)

Lol Denny, not much of anything available in my tank right now to share and I'm 20 mins. north of Edmonton so it's a bit out of the way. I may be able to get some help closer to me, we'll see(I hope).

My main problem now is muscles to move this tank off the stand because neither myself or my hubby can lift it due to back issues =/ I dragged Shaun & Chris out here to get it in my house.

Just get more cut with a plate on each end and screw em in :) then you dont have to move anything...If your skirting it anyways
the weight will go down when its full unless you plan on rocking it I dont see a problem.
My stand is 8 feet and only has a center brace... its 1 1/2" 1/4 wall but still its got 300 gallons on it :)
And heres my 180 dual rack i made with No Center braces in the top part of the stand...and its a 2 piece so its not even welded together LOL
Rock solid and 1 1/4" I have alot of faith in thicker softer styrafoam to take up that bit of flex in the stand.

All that being said however... I didnt build it so theres no warrenty here LOL

1" tube with 1/8" wall would put you at about 100MPa so depending on material and your ability to live life on the edge you're technically OK as even plain carbon steel is around 220-250Mpa. So either make sure it's secured to a wall or something to prevent it from being bumped over or take the advice of others and add some reinforcement. Personally I would get myself some 3/4" ply and screw it to the frame all around and cut some access panels in it for doors, that would make it plenty rigid, plus who likes unfinished open stands?
