Readying Top Panels for Permanent Seams

 One of the things I really like about the cradle/mold is that you can roll it up on either side or end to get at the other side of the panels.  I have it rolled on its side here to finish tightening and aligning the stitches.
 In this shot the cradle is standing on the aft end to better get at the seams for "tack welding."  This is nothing more than applying "super glue" to the seams to hold them in place while I install epoxy fillets and fiberglass tape to hold them together permanently.
Here's a closer shot of the "tack welds," which is a relatively recent innovation to CLC's method.  It makes it possible to get the seams much more closely aligned before the epoxy work.  You can see the glue spots about half-way between the copper wire stitches.  After the glue is applied it is sprayed with an accelerant the causes it to harden in 10 -12 seconds.  That way if the seams are still slightly misaligned I only have to hold them in place for a short time before the glue takes over.  After the glue is set, the wire stitches will all be removed before applying epoxy fillets and fiberglass tape.
