You didn't ask, but I'll tell ya anyway [img]i/expressions/face-icon-small-smile.gif[/img]

To remove the covering - use a soldering iron! Don't use a knife, razor blade or any other 'knife' - instead warm up the soldering iron and with a metal straight edge - just drag the iron over the covering and it will melt a cut line - nice and neat to boot!!!

Remove the covering and glue in the triangle balsa, then cover the strips with some scrap...

hope this helps...
