Default Basswood spars?

Does anybody know where I can order a single 1/4 x 3/8 x 48" basswood spar? Would prefer not to splice 2 smaller pieces.

Lonestarmodels.com balsausa.com and a few others. You can also check the local lumber yard for cut off os moldings. Some of the pine/doug fir, birch work very well. They are also cheaper.

Depending on the airplane you are building only balsa is needed. I have built many and/or designed some profiles and never used basswood spars, just some food for thought and it might save you some weight. In fact, I only use 1/4sq. balsa for my spars and there are over 200 of my sledges out there with no problems. Jeff W.

I am pretty sure this is for his OMP Hybrid 92" and would think the basswood would be a must The problem with lone star is you have to order $25 minimum.

Crash,
Looks like you are going to have to bite the bullett and spend the $25. I was at my LHS yesterday and they dod'nt have what you were looking for. Sorry I could'nt help.

Thanks guys. My LHS has 24" pieces. I guess will splice 2 together. The hard part for me is keeping them perfectly straight.

Splicing wing spars is not hard once you know how.

Pin along back of a straightedge on your building board, so it can't move towards you.
Two or three places is fine.
Then use the other side of the straightedge to align your spar halves before and during gluing.
Pin the spars down against the straightedge while the glue dries.

Here is a good explanation of how to engineer the glue joints. [link=http://www.modelairplanenews.com/how_to/splicing_wood1.asp][LINK][/link]

Hope this helps. Keep the pictures coming on the Hybrid project. [8D]
