KR> Wood For kRs
I'm using hoop pine in my KR-2S. It's 10% heavier than spruce but also 15% stronger. It was approved as a substitute for spruce and douglas fir during WW2. I think they built Mosquito bombers with it. I buy first grade timber from a boat building supplier and cut it to size. As John says, you lose a lot in sawdust and shavings and the odd reject, but it's less costly than ordering the sizes from the plans. I've used hoop pine marine ply on the fuselage too. Hoop pine ply is supposedly the best marine ply you can get - at least that's what the boat builders claim. Just a little hard to find in the smaller (thinner) sizes. It's great using something that's locally grown or manufactured though. Gives us Ozzies a taste of what builders in the US take for granted :-) TK On 20 January 2016 at 05:54, John Martindale via KRnet wrote: > I actually imported a rough sawn piece of 8" x 2" spruce to Australia > through a local lumber yard and cut it down and smoothed to size myself. > Didn't take very long and worked out heaps cheaper.

I actually imported a rough sawn piece of 8" x 2" spruce to Australia through a local lumber yard and cut it down and smoothed to size myself. Didn't take very long and worked out heaps cheaper. Had to work around a couple of faults in the core of the flitch however and have the results inspected. I reckon you lose about a third in sawdust and shavings. We can now use a local timber called Hoop Pine which seems similar to Douglas Fir in properties but it wasn't easily available when I started out. It is cheaper again. We also have a ply made from it.
