Ahh, from the days when Sport Aviation was worth reading..

Today was 'mounting day'. It was time for the wings to meet the airframe. Although my holes were all drilled to 1/4" I started with 3/16" bolts so the wing could quickly be put in place then I went back and through drilled some of the holes while installing 1/4" bolts that had been tapered to a bullet point. After that I calibrated two digital levels (they needed it) and setup the wings dihedral at an initial 1.1 degrees on the front spars. The 1.1 deg is what I calculated as an initial angle to give me something close to 3" dihedral. Which turned out to be close as I later measured 2.5" with string sag. I've no idea how much sag at this point. The rear conduit struts didn't have the 5 deg angles so I just let them droop vertically to the floor as supports and adjusted them to give 2 degree washout. Tomorrow I'll readjust the rigging and go about making the final rear struts then the front ones after that. Very cool to see the big visual change, finally.
Speaking of 'big visuals' a box of wing covering showed up today. I didn't realize how big the box would be. Cool.

Thanks Dan, I’ll have a look for that article. It’s the thinner fuselage tubing I’m trying not to overheat.

There is a welding trick that works for these short pieces of tubing for failrleads or hinges. One can take a stack of washers with a nut stacked between each fender washer. Thread the stack onto a bolt and turn this down on a lathe until it barley slides inside the fairlead or bearing tube. Now weld it and the washers are a good heat sink to keep the blobs and crust away. There was an article on this is Sport Aviation years ago...

Hi again guys, I’m about to weld on those 12 fairlead holders and I’m not really looking forward to it. I’ve been experimenting on scrap pieces to try to find an easy way of attaching them. Using the plans method of tube to tube I’m having to put in a lot of heat to fill the gaps. The inside of the thinner tube gets a bit blobby.
I had some box steel spare and I’ve split some 1/2” pieces of it to make mounts for the fairlead rings. The welding is easier. Photos below.

Glad I could help. I learned that trick from Mooga.

So simple a cave man (me) can do it. Thanks so much, This will save me a lot of needless monkey business.
