Here is another option on the drill jig. I used 1/4" aluminum bar stock.

like that, one for each type of surface !
way to go man!

Yeah, I'm going to have to make one of those jigs too.

Do you start with the outer edge to get the surfaces to line up or what's the best way to line things up properly?

I have done the jig, with the following spacing

Pin-1 inch-pin-3 inch-pin-3 inch-etc.....

so, there are two that are close together, and for any surface, I make the two outer and two inner, only one inch apart.
the rest are 3 " apart.

the one I have, when I get to one end, I then turn it around, so i drill two holes, 1 inch apart.

The advantage of the plexiglass, is, you can look thru it and align the jig with the central line of the hinge for the surface.

the jig itself, has a central groove, which was cut out 1st (this is a "straight" cut, then the holes were drilled.)

Just beveled the rudder and fin LE/TE.
SO far so good.
this is the fastest building airplane I have ever built, with regards to actual time. Much easier than my first 3 Daltons.

Last step, will be to glue on the bottom to the rudder with the hard point for the tiller arm.

Excellent job getting no gap between the surfaces , your using piano wire to connect all the hinges together, very cool .
That vertical looks small compared to how large that rudder is ? I like your work , very good post Cam have enjoyed all of the Dalton progress .

Thank you Rusty. I appreciate you. Got the last of the work I can do on this airplane. And so far, so good.

The rudder is now finished.


Using my White Rose tail wheel, I prefer the tiller arm. This avoids the use of springs, and thus, when in the air, there is no loading of the servo secondary to springs. I obtained this hard wood dowel, and marked the location on the rudder, whereby I can have a tiller arm fixed to the rudder via a ball link. Found the spot and drilled it using a Forstner Bit. Then, using the drill press, I drilled out the hole for the ball link, and then I glued it in with poly-u glue.

Here is the final result, the rudder and stabs have a removable hinge line, in that, there is piano wire thru the Robart hinge points.

at this point, there is nothing more I can do, Until I receive the remaining parts to my kit:
1. Wheel pants
2. main landing gear
3. canopy (plastic)
4. hatch parts / wood
5. wing tube and wing tube phenolic
6. cowl (top and bottom)

Once I get the wing tube and phenolic, then I can build the wings, and proceed some more.

Signing off for now, you all have a great day,

Cam
