Working on the Spars

Here, I'm getting ready to drill some holes in the two upper wing main spars.
The level is to help make sure the holes are perpendicular to the spar.

An adjustable stand is a great way to get a helping hand without bothering anyone else.

Fine tuning the setup. It's hard to see, but two scab plates are under the spars along with some
scrap wood to prevent tear out. I'm using a Forstner bit.

Here's a closeup of the Forstner bit.

These are all the scab plates for the wings. They're 1/16" pieces of plywood
that will be epoxied to the spars wherever brackets attach to provide a solid place
against which the brackets can be bolted.

A wood plane and some spruce shavings.

Getting ready to trim the wingtips.

I created a few of these pieces of wood to help me get a straight edge set up the correct
distance form where I want a cut to make it easy to cut along a line with my worm drive saw (i.e., circular saw).

Part way there! The hole at the tip is for the wing tip bow, a tube of aluminum.

Done with the upper wing main spars!
