Default Next Steps

Before getting the spars located in the racks, one last activity - cutting the internal flying wire pin holes through the front spars. I am doing both the lower sets of spars together then when it comes time to rack I will move to just one at a time

Pics below, setting up the plunge router to cut the 1" hole.

Default Racks

Next step, get the spars levelled an into the racks, ribs slid on. Next step will be to do the drag anti-drag wires but I am still waiting on them from Steen (they were not shipped with my original order as they were late coming to Steen and missed my wing kit delivery.)

It looks like a real plane part.

Last two pictures.... trammel points used to ensure the spars are square relative to each other in the horizontal plane.

Looking good Cam.

Keep in mind the pattern of drag wires before drilling holes. Just to keep them from interfering where the aileron hardware needs to be.

This was a little puzzling for me and I needed to draw up a schematic before I drilled.

Have you made your drilling guide block yet? That was a bit of a teaser!

Eric,

I chuckled when I read this. I have marked the top and bottom on front and rear so I know WHERE I have to drill, just struggling with HOW I will drill. Its easy on here to show all of our good work.... here is some of my bad - the attempt to make some jigs in 1" x 1" Aluminium square rod. Its nice for marking/scribing, but I can't drill it straight.

Attempt 1 : 35degree. Looks good from here.... turn it over and you will see it come out off centre

Attempt 2: Different layout, you will see that both sides are off centre, but more importantly not equally off centre and the angle comes at at 38.5 degrees which is useless for anything

So I can't drill these pieces without either the metal or the drill bit wandering.

I have a portable drill press, but getting it square and exactly at 35 degrees is problematic.

I have been watching Ray Moellers video and am going to try that method for my first wire and see if that works.

It is the one drilling activity I am very nervous about. The iStruts and the internal pin holes were easy, these ones, not so.

I tried one of those drill guides and was not happy with the results. Maybe it will work when you have only the spar. I was working on an assembled wing.

Cam.
I drilled through a high density wood, not much chance of rill bit drift because of grain pattern.

To do the drilling through the wood, I used a brad point drill bit.
On my Delta drill stand (that's the best I have) and adjusting the work plate, I figured out the angle (on a couple of scrap wood samples).
During this I was blocking and clamping my samples that they would not move out of position during the drill. Then when it came time to drill through the jig, again clamps from all sided and blocks to stop shift.

Then I glued in a steel tube as my drill guide.
Using a 12 inch drill bit with masking tape I could visualize the laser beam for one axis and I used a glass fiber rod down the diagonal for the other axis to align up the drill bit.

If you want to borrow the jig, PM me.
If anyone else has a jig they made. Maybe they can lend.
