Wood for tank wedges

[Vlabruzzo]

What would you guys use? Treated, standard, pvc?

When replaced my fuel tank I used AZEK from Home Depot.
It won’t absorb water or rot and using their glue made for it you can bond pieces together to get the thickness you need.
You also work it as you would wood.

Cool. Thanks

Never use treated against aluminum. The preservatives will eat through the aluminum quickly.

Im making them out of pvc. I assume the cross braces should be regular lumber as well?

They appear to be regular lumber originally.

Correct, but that doesn't mean it is acceptable for the application.
Lt.Mike hit the nail on the head.
Azec board or similar for spacers.

Just made up some spacers out of azek. I jad tank made .5 narrower. I made up 2 inch blocks to screw through and will use 1/4" 316 stainless lag in each bracket. I had brackets welded on as well. I guess still use regular lumber for cross braces? I planned to. I was also going to add azek blocks under them on the bulkhead for extra support from downward pressure.

I glued strips of neoprene underneath my lumber supports with 5200. I believe mine were regular lumber too, and I was able to re use them. You want some type of buffer between the lumber and the tank so it won't corrode.

Sounds like you have a good handle on it. The goal is avoiding any surface contact that will create crevice corrosion.

Awesome, I'm concerned with getting rhe supports back in with the tabs welded on.

That's why I chose neoprene... it's not too thick.

You might have to shave down the lumber a bit when you dry fit everything. I used an electric planer to accomplish that.
