Iv’e spent some time sourcing materials the last two months and I found out a few things; the most important of which is that it is good to look for local suppliers of wood products. Having said that, I am going to be buying my lumber from Aircraft Spruce. “What the what?” you may be thinking, well here’s the thing, I have been poking around for spruce and doug fir as well as marine plywood. The 1/16″ plywood is a flat out no-go any where else locally. The 1/4″ and 1/8″ plywood can be found locally but the quality varies widely as does the price. I thought I had a supplier for a really low price, turns out the quality matched the price.
I had much better results in the Lumber search in that I could find good quality doug fir. The price for it matched or in some cases exceeded the cost of spruce, which I could not find locally, at least not in quantity or quality. So I am back to Aircraft Spruce, not that this is a bad thing mind you. The main reason I was looking to buy locally is I try to do that with everything. Buying locally improves the local economy, and buying from small business helps revitalize the vanishing middle class. At least I can say in this case that I will be buying regionally from a small/mid-sized company. Aircraft Spruce has a store down in southern California, it’s a seven plus hour drive from San Jose, but paying for gas is considerably cheaper than the freight costs having it shipped up to me. I plan on buying stock sizes and milling myself to keep the costs down and ensure ready availability.
Now that I am back to were I was last month as far as the materials quest goes, I am more prepared and knowledgeable in the area of aircraft lumber. I know what I can get and where to get it, as well as what substitutions I can make for specific applications. It looks like the plywood is going to come in just shy of $1,000 (materials and tax). I need to calculate the lumber requirements, that is this weeks project, but I am estimating that to be about $500. I will need a few odds and ends to have on hand, basic airframe materials, so I am planning on a $2,000 trip including the round trip fuel for the van and me. It’ll be a long day but a fun one I am sure.
The only tool I need to look into at this stage is a plainer which I am sure I can find at Harbor Freight in Newark. I also need to make a router table top and several jigs for cutting precisely duplicated wing ribs, all of the materials for this stuff I ether have or can find locally on the cheap. All-in-all I think I am getting really close to making a lot of saw dust.
Until next time, blue skies and tailwinds,
