Finished work on the wing cart - 10 hours

Big long day on the wing cart. Now I will admit that i am way overboard on the cart. It is overbuilt. but considering that I have to move the wings out of the garage and put them on transport to storage. A strong solid wing cart is WAY better than a flimsy wing cart.

I began the day by dissembling the wing stand.


I then started to cut down the various pieces to the suggested dimensions on the VAN's drawings. Next I started to assemble the leading edge support structure and installed the castors.

Took me some head scratching to figure out how high to mount the inboard spar holder to get a nice level wing. But after some thought and measuring I figured it out and cut the plywood. I then fit it to the cart frame.

I test fitted the wings at this point to ensure that all was correct and I then removed the outboard support brackets that were installed to fit the wing stand.

Next I wanted to stiffen the support structure, so I fastened gussets to the frame.

Now...To fill in the leading edge support. I had bought some 1/4" plywood and scored the backside to allow me to curve the wood.



The depth of the cuts where quite deep.

But this allowed me to follow the leading edge curve quite nicely. I used lots of glue and brad nailed the skin to the contour.

Next. I wanted to secure the inboard spar to prevent the wing from sliding off the support. Now some build logs use bolts wrapped in duct tape and just stick in the spar holes as a method of securing the wing. This is just fine, however I wanted to do a little better, so I bought some 3/8" dowels and after using a cardboard template, I transferred the holes into the wing stand and installed the dowels.

Now....Mental note here. 3/8" dowels leaves no room for error as it is a tight fit for the wing spar. So after a test fit...I decided to lose 1 of the 2 dowels.... much more forgiving fit. I then painted the structure....of course no NEED to do this, but for it's clean and nice, so why not. I then used contact cement (3M #77 adhesive spray) and installed the foam padding.


 
And presto chango....I am done. Wow this cart is nice to move around.  Lots of work put in today....but worth it.
