Well the preliminary spar work is done.
With the main center spar done next I cut temp wood wing rod (plug) to fit the interior space. I used poplar for this.
I machined the poplar to fit snug (no slop). Then chamfered the corners to clear the epoxy fillet.
It took some time to get the fit just right. I am glad I opted for wing tubes instead of would plugs like the plan calls for.
Fitting a set of wood plugs just right and tight but not to tight would be a pain in the hinny.
The poplar was then waxed up real nice.
They were then inserted into the center spar to create the correct plan for the out wing spar.
The 4 plates for the two outer spars were left wide, to be sized after glue up.
This meant I only needed a square plane at the but joint.
The outer aspen spars were then epoxied into place ends pre squared.
They were just finger pressed against the wood plug. Needs to come back apart easily.
I did not glue the top plate down until the bottom was set so I could assure nothing slipped.
Then the plywood was routed flush with the outer edge of spar.
With that the spar work is complete.
Next up wing ribs.
