Title: Gluing two balsa piece at an angle Post by: WeekendFlyer on March 12, 2022, 09:27:53 PM I wanted guidance / tips and tricks to join two balsa pieces at 45 degree angle.
Please guide me to do it with accuracy without leaving any gaps in between. Thanks, Title: Re: Gluing two balsa piece at an angle Post by: K K Iyer on March 12, 2022, 09:49:23 PM I wanted guidance / tips and tricks to join two balsa pieces at 45 degree angle. Please guide me to do it with accuracy without leaving any gaps in between. Thanks, You will need a block of wood with fine sandpaper stuck on. Use rubber solution (called Fevibond I think). And a drawing board on top of a table. Place the wing half at the edge of the table, and prop up the tip to the required height. Preferably tape it down. You can see a small width of balsa on the top edge. (Pic #1) Place the sanding block on the table top, touching the edge of the drawing board. If the block has square edges, the sanding surface will be perpendicular. (Pic #2) Run the sanding block a few times in contact with the edge of the drawing board to bevel the inner egde of the wing. Repeat with the other wing. You should get a joint like this (Pic #3) Hope this helps.

That's a a good technique. What's techniques other flyers use ? Can we have more suggestions? Here’s a useful tip. Make tiny pinholes in the surfaces to be joined. Use 5 min epoxy (Araldite Rapid/Klear), but not too much. You’ll get a strong joint without needing a dihedral brace. |
