balsa cut question

[pisagor]

Hi guys.How can i cut balsa like picture. I'm building a flying wing and i hate sanding elevons

Can you suggest me easiest way?

 

[earthsciteach]

I was going to say, "sand it!" What are the dimensions of the balsa?

You can buy pre formed pieces for ailerons and things. Otherwise sanding is your best choice. I can never get a straight cut that long with the grain.

If it is a large piece, use a fine saw to cut groves about every 1/8 inch or so from the thick side to the point. Then use a flat blade screw driver to gently break the tabs between the cuts. Finally, use a sanding block to finish the surface. 180 grit or finer should do.

If it's a small piece, use a hard backed sanding block or file to cut the taper.

Go slow either way.

Check this for sanding guides to form your taper....http://www.rcuniverse.com/forum/m_9839305/printable.htm

The smartest is to use a plane if you do not have a band saw.
