Weight cap. of 3/4 inch plywood
 

I am building a stand for one of my rain barrels, (full capacity 50 gallons,
or ~ 420 lbs).
I am using 3/4 inch plywood, and plan on supporting it every 60 degrees of
circumference with 2 x 4's with 2 or 4 in the middle of the circle.
Think this will hold 420 lbs.of water, plus 25 lbs of barrel weight? (Total=
~455 lbs)
Thank you.

It is really about balance. one 2 x 4 can take the weight but you want
to distribute it evenly.

Agree

What he's described is way more than min to support it.

You must be over thinking this project. Is the ground surface not good
enough to hold a barrel of water?

What kind of barrel are you supporting?

Maybe under-thinking it ?
I'm thinking that the base - under the support - is more critical.
Rain barrels will over-flow big time - during the heavy downpours.
... make sure the ground beneath the barrel is stable ! then -
a big sidewalk paver - with a couple concrete blocks on top -
will cost almost nothing in dollars or time - and provide a nice
raised surface - get your rain barrel up high enough to get a pail
under the drain tap.
... and a bonus - no rotting wood to attract bugs !
or fall apart in a few years.

He may be thinking that the barrel up off the ground will gravity feed
for irrigation, hand watering, eliminating a pump.
I have this with my 150 gal aerator tank. It will flow enough water to
fill a toilet tank with the power off but you are not taking a shower.
I went with 4 concrete posts (6" pvc full of concrete) and PT 2x6
stringers and decking. I think plywood will just de laminate.

You need to use the Sagulator.

It will calculate the sag of more species of wood than I knew existed based on
total load, load distribution, support method and a few more factors.

It crossed my mind too but I don't see anything sagging. The barrel is
self supporting around the circumference and the supports will be
directly below it.

Yeah, but where's the fun in *not* using the Sagulator? ;-)
