Awesome DH-2 build Des. A few things...

A GREAT idea to rig corresponding wires on both left and right at the same time to help the wings to stay aligned!

How can you drill at the same angle that the rigging lines will adapt after assembly? I know that there would be some drill slippage, and even though the drills to be used are positively tiny, there would still be some touch-up to be done if your wings are already painted (as I expect they will be). Now, of course, you're not using a drill press, but a tiny hand-held pin vice, and can take it relatively easy. Do you use, for instance, some masking tape over the wing surface to a) protect it, and b) give something for the drill to grip into initially? Would the tape stick to the drill in this method?

I also purchased some of "Bob's Buckles", and they have tiny eyelets to anchor both sides of your rigging. I suppose there would be less "need" to drill the mounting holes for these at the same angles that the finished rigging would adapt. Also there will be sometimes when you will have two rigging lines emanating from the same position on the model, that will result in two opposite directions for the rigging wires. Do you then drill two adjacent holes at the appropriate angles, or drill perpendicularly (perhaps only on this occasion), allowing two rigging wires to emanate from the same hole, and travelling in almost opposite directions? Would this possibly make the rigging wire look "out-of-place" because it would come out at 90 degrees to the model, and then bend to the direction of rigging? Would this "weaken" the rigging or stress it unneccessarily? The tiny eyelets mean that you can connect several rigging wires at the same location.

I know that I'm going to break a LOT of drills until I learn the correct technique, so I thought the best preventative method would be to insert the drill as deeply as possible into the pin vice, leaving the smallest amount out to work with. Now, to drill at these angles, I'm guessing that would necessitate having more drill bit extending from the pin vice.

Finally, how do you gauge how deeply to drill into the bottom of the top wing? Do you use calipers to measure the thickness or use the old Mk1 eyeball? Perhaps just to drill until you feel there is a deep enough hole to get "purchase" on the monofilament?

Thanks for all your help Des.
