How do you do trailing edges?
« on: April 03, 2013, 02:50:30 PM »
Here are two of the most common trailing edge configurations. No1 has the TE fixed to the ribs then the TE sheeting added. No2 has the TE sheeting lapping over the TE strip. For strength, I prefer No2 but how do you shape the tapered piece at the back of the ribs?

If the glue joint is good then either should be strong -- but your #2 should be more forgiving strength-wise (and less so weight-wise), as well as putting the seam between wood and wood where it's less visible.

I'd shape the TE piece roughly to shape, then install it, then sand it and the ribs together to get a nice match.  Perhaps "sand gently" would be a better way to say it.  Then put on the TE sheeting.

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

I use a table saw with a tilty blade.

Thanks gents.

Tim, on other styles of TE, I put masking tape on the ribs adjacent to where I want to sand and then sand gently.

I use #1.  Sand the back of the ribs and trailing edge sheeting nice and flat with the long block sander.  Then glue over sized trailing edge piece to them then use a razor plane and long block to get it all tied together nice and smooth.

Either way will work. Just go with whatever you are more comfortable with getting straight.
