Thanks for all the input.
I have decided to go with the hoop pine which I sourced at Mathews Timber.
They brought out a pack of 100 No. 1 Clears from which I selected 4 pieces
of 8" x 1" x 17'. The cost was less than $3 per foot!
Today I have been ripping them into lengths and then using my favo
I am ready to order my timber and being on a very tight budget, I am
seriously considering douglas fir as an alternative to spruce. The spruce
kit machined and delivered from an interstate supplier (Australia) is going
to cost $3,000AU ($2,365US). Douglas fir on the other hand will be about

In my experience, douglas fir is about 25% heavier,
but it is also stronger. Just make sure it has the
proper grain count and runout, ect...

I am seriously considering Douglas fir as an alternative to spruce.
Hey Darren, you have a better alternate right there - hoop pine lumber and
ply - same selection criteria.
I have made a careful study of the known alternatives and hoop pine is no
compromise at all - good stuf
The supplier I spoke to in Newcastle said that hoop pine was more brittle
than fir, similar weight, same price and more difficult to get in aircraft
quality. I had discounted it because of its supposed brittle nature but I
do like the idea of building from an Australian timber.

Here's the "Wood Book", it should contain all the info that you need to choose
a wood type for your KR.

On http://krnet.org/ there is a link to the old paper KR newsletters,
downloadable in pdf. Many years ago a gentleman document
Here's a PDF file that does just that, gives you a selection and test
methodology for the non-certified wood that you use in your project.

Lots of airplanes have been built using Douglas Fir. It's a little heavier,
but also stronger than spruce.

Darren,
Fir is a good choice, I have used fir for my airplane. The complete fuse
without plywood weighs 22 pounds, if I had built with Spruce it would
have weighed about 19 to 20 pounds. Not much difference if you ask me.
Truth is, the frame of the airplane only makes up a small part of the
whole

Many Aircraft in Aust are from Hoop Pine. Including my mates Corby Starlet.
He was VERY happy with it.
