KR> KR-2 Wood (a bit long story)

[bepe]

Hi Steve,

When I wanted to build my KR-2 in early nineties, I was in the same situation 
as yours, seeking local wood,
avoiding importation of expensive Sitka Spruce.
I live in Indonesia, plenty of wood, found wood called RHAMIN (in Sumatera and 
Borneo), it has very nice strait grain.
Treated properly (Kiln drying processed) and selected, got about 20% only from 
the total volume. 
As plywood I used marine plywood (I though it was superior to aircraft grade 
plywood).
Hardware imported from Rand Robinson, engine with Happi conversion kit.

 Finished. But finally hesitation to fly came to my mind because of this 
un-proven material.

As I was very eager to fly, then I was mad, closed my eyes, closed my ears, I 
bought/ imported Sitka Spruce
 and Aircraf grade plywood, all wood kit for KR-2 (from Aircraf Spruce compay).
And started to build again a KR-2, again importation of hardware as I did not 
want to take the hardware 
from  the first KR-2 I have built. Put a Revmaster 2100D engine. It ends up I 
built 2 KR-2s.
This KR-2 flew for the first time in 1997, and maintained till now.

No .. no.. I don't suggest you anything, but please remember the post from Greg 
Martin bellow

Just remember.  Any structural plywood will have a min. of 5 layers.  I have
seen a 3 layer plywood claiming to be structural.  But that was for
buildings, not airplanes.  And the veneer is the outside layer on both
sides.  But I would stick with Birch or Mahogany.  Doug Fir has a very good
chance of having grain splits caused by pitch pockets.  Good luck in your
search.  Remember, you safety just cost more than a bargain wood.

KR> RE: losing job

[Fred Johnson]

Sorry guys, I know this is not technically KR related, but found out today
my company is closing it's doors. The economy has taken it's toll on this
industry and they made the decision to pull the plug on it.

I have a KR2 in the boat stage. No plywood on her yet. if anyone is
interested I'll make a deal on it.

I have 800' ceilings at the moment, but will get out around lunchtime, there 
by 2PM, I suspect.

I was telling my old Air Force roommate Mark Chamberlain, who's driving in 
from Iowa, that there would be a keg on the premises shortly, and he said 
"now I'll have to speed the whole way"...

Veneer is a very thin, single layer of wood generally used as a trim 
or cover material used in furniture making.  It is not used in the 
structure of an aircraft.  You are looking for solid wood stringers 
and multi-layer aircraft grade plywood to construct the KR.

KR> Douglas Fir Veneer and Yellow cedar Veneer

[Peter Drake]

Steve

A veneer is a very thin sheet of decorative timber usually bonded to another 
cheaper timber. Also plywood is made up of veneers maybe only 1mm or less 
thick.
You should be looking for clear lumber for your KR.
I don't know what exact terms you use in the US for this.

get Douglas Fir Venner and Yellow cedar Venner but the word Veneer makes me 
confused if am getting the right material. Please help me on this.

And what size should i be searching for in terms of thickness and both 
length and width

What country are in. Because is some cases. You can look to specific local 
woods that can fill the bill. I have used both Stika Spruce and Douglas Fir. 
The Fir is about 12% heaver but is about 15% stronger. So there are trade 
offs.

So, let me know what country you live in and I will look at the variour 
woods and their weight and strength.
