Alright, two more minor issues to take care of for you guys who already have your kits. Don't you guys just love being my guinnea pigs?!!!
In your kit you have two 1/8" light plywood parts "W17". They look like this:
Throw them away, they are no longer needed! Instead you will be using the four 1/4" balsa wood parts which are numbered "W17t" and "W17b". The part shown above was for the original wing joiner design and I simply forgot to remove it from the laser file.
Second issue, you should have received four 1/8" light plywood "W18" parts as seen below. Instead you only have two. They are simple enough to make but I would be happy to provide them for you if you prefer. Please note that the hatched area is a jig tab which will be removed from W18 before you sheet the bottom surfaces. If you decide to make these yourself it is not really necessary to include the jig tab. Again, if you would like a full size PDF file of W18 please ask.
