thanks. i have about $55 in wood, $45 for carpet, $15 for paint and primer for inside, $65 for steelflex epoxy, $25(i think) for switchpanel, probably close to another $100 for misc hardware and paint preparation supplies. thats a good estimate. i have most receipts somewhere. here is a couple pics of the wood bracing.
I might have suggested treated lumber but you can still seal it ?? Good looking job!
