Default RE: Sig Hog Bipe

Okay, the trailing edge sheeting is on. I read the next step about 50 times, looked at the plans and parts and even then couldn't bring myself to do what the directions were asking ...

The next step calls for sawing through the first 4 ribs all the way to the main spar. Check out Picture1, I outlined the portion that needs to be removed. This is an un-natural thing for this builder to do. After convincing myself that I could "fix it" if needed, I went ahead and cut out the material. Of course, this was the right thing to do, but it really felt awkward at the time.

It must be the day to get stumped - it was that way at work too [:@]. Anyway, the next step was the sheer webbing. Here's where I have to ask the Hog experts out there if this is right ...

It appears that there are only 4 sheer webs per wing 1/2 on the upper wing (Picture4). I am accustomed to putting sheer webbing across the entire wing, but it appears that the Hog doesn't need it?? Is this correct? Hopefully someone who's built this kit can weigh in. I went ahead and installed the 8 total sheer webs that I know are called for - they are curing at the moment.

I decided to look ahead and true up the leading edge sheeting for the next step. I couldn't believe how "un-true" this was. Now I've built my share of kits over the years and have never experienced this poor of a wood selection - this is not a knock on SIG as this can happen to anyone ... but geez. [:'(] I tried to snap a picture of how bad this was. Check out Picture5. This is sitting as square as I could get it on my glass table top. Not only is it bent up and the ends, but its warped across the legnth. This piece may get tossed for a sample from my scrap building wood pile.

Picture1 - This is what needs to be removed from W-1T - scary
Picture2 - Once the scrap is removed, the ply piece fits snug onto the bottom spar
Picture3 - Starting to take shape
Picture4 - Here are the Sheer Webs - only 4 per side on the Top Wing?? Is this right?
Picture5 - Sheer Webbing clamped down and curing
Picture6 - Picture doesn't do it justice - this was one "out of shape" piece of balsa
