Hi guys, I'm back. Finally have the money to get this project going again! I just graduated from high school too, so I have time to do things. I'm not sure what happened to the old thread, but oh well.
Anyway, I left off with the frames. I have all of them cut out and tonight I sanded them neatly and made them pretty. Hopefully tomorrow I can purchase some wood for the stringers. I just bought the 8oz polyester fabric as well, it should be shipping out tomorrow.
One question though - would white oak be suitable for stringers? I literally cannot find any good softwood around here. I live in the middle of hardwood country, and the local Home Depots and Lowes only seem to carry hideous Douglas Fir and crazy-expensive Radiata. However, there's a hardwood store nearby that sells wood in dimensions suitable for my project.
Doing some research, it seems Douglas Fir is ~0.5g/cc, while WRC is ~0.35g/cc. White oak is ~0.7g/cc.
By the wood list, I estimate the total volume of my stringers to be approximately 23,000ccs. So my estimates for weight are as follows:
DF: 0.5g/cc * 23000cc = 11,500g = ~25 lbs
WRC: 0.35g/cc * 23000cc = 8,050g = ~18 lbs
WO: 0.7g/cc * 23000cc = 16,100g = ~35 lbs
Man, some big weight differences there. The book recommends WRC, it seems. Will 17 more pounds affect anything? I'm really not sure if I trust the DF and WRC we have here - full of knots and bad grain. This wood store also carries Sassafras, though. I'm also worried about pricing - I would like to keep my stringer wood under $50.
Maybe I'm overthinking this...
