Default RE: Sig Hog Bipe Build

Sunday (2nd Weekend day) Status:
Well, I am stopping for now. I find myself trying to get too much done too quickly and am making some mistakes. Nothing big, but enough to know when it's time to hang it up for today. However, I did make quite a bit of progress. I got the LE wing sheeting for the top wing bottom in place and it is drying after using 30 minute epoxy. I have found something about kit building that I sort of knew after building my Somethin Extra. I really do not like doing Leading Edge wing sheeting. It seems I still haven't found a real good system for setting it in place and gluing. You can see in one of the pics for today a new trick I tried. When it came time to glue the front edge in place, I pinned it down and then tilted the entire building board up on edge. Then it was just a matter of dripping small amounts of Medium CA along the leading edge joint. It helped the CA to run along the edge, covering the entire length. I then sprayed the outer side of the sheeting with straight ammonia, brushed in 30 minute epoxy onto the ribs and along the LE joint to add strength. Then I pinned the sheeting in place and am waiting for it to dry.

One note on mistakes. In one of the pics below, you can see the area of the top wing mounting block and a couple of pins sticking in the LE sheeting. I made an error in making sure the mounting block holes were really square to the wing. In the instructions, it does say to check it, but I just didn't get what they were asking me to do. I made sure the mounting blocks and plates were level to the rib brackets and using a straight edge made sure the cabane strut would cross the middle wing brace without touching. Well, the most important part was missed by me. I forgot to make sure the two holes were lined up front to back of the wing. When I started filling in the area where the LE block was placed, I visually noticed that the holes were not lined up front to back. I remeasured the distance between the ribs w-1 and found it to be 29mm. I spit the difference to 14.5 mm to find the center. The rear hole was right on, but the front one was off to the left. In the picture you can see that I have filled the hole with a dowel and will redrill in the right place after the titebond glue dries.

As indicated, I am stopping for today. The playoffs are on in a couple of hours anyway and I do want to watch. Also, I am allergic to CA and I am starting to feel the affects. Although I am building in my garage, the ventilation is not what it should be with the main door closed. So, will take off for now, and re-start during the week after work. Enjoy the pics.
