Finishing the Wing Assembly Stand – 4 hrs

Today is the day to finish the wing assembly stand. This is taking longer than I expected.

First I cleaned things up a bit in the garage. Tools and sawdust were piling up. Then I stored the wing parts inventory on the top of the stand. That freed up some space also. Then I began working on cutting aluminum angle for the spar hangers. I could not find any instruction anywhere on how high above the floor to mount the spar so I selected 43 inches for the height of the spar bottom surface above the floor just because it seems about right. I’ll see if that works out later.

I cut 1 x 1 x 1/8 aluminum angle pieces 12 inches long for the horizontal hangers. I drilled one 1/4 inch hole near one end for the anchor hole to the vertical column and another 1/4 inch hole near the outer end for the diagonal brace. I cut the diagonals from .75 x .75 x 3/32 aluminum angle 18 inches long. After mounting the hangers for the inboard ends of the spars I used the shipping crate and wood blocks to support the other end temporarily. After placing various things under the spar to get it approximately level lengthwise, I measured the height of the end so I could drill holes in the columns for the outboard hangers. To get the measurement right I had to install a short piece of 1 x 1 x 1/8 angle on the end rib of each wing by match drilling two 3/16 diameter holes in the rib. Once mounted I could measure the height of that surface above the floor and transfer that to the column.

More Wing Assembly Stand – 3 hrs

It has been a brutal week at work so I did little to no work on the wings during the work week. This morning I cut lumber to to the length necessary to finish building the wing assembly stand. In addition to several 2×4′s that I bought at Home Depot I cut several pieces of 1×12 that I salvaged from the wing spar shipping crate. After a couple of hours I had to go into work again today.

Later in the evening I assembled the pieces with the help of my wife. I also salvaged a large piece of 1/4 inch plywood from the wing shipping crate to make a shelf on top that really stiffens up the whole structure. I’ll store materials on top as well.
