Douglas Shrock, you are an Artist! I am enjoying building your design and I appreciate the work you put into creating it.

Thank you.

Do not sharpen the wing probes, as you will skewer your hand at some point and get blood all over it.

That's quite a building jig in last couple photos.

Thanks. That's a variant of my Guillotine fin jig. I figured I'd give it the "acid test" by building one of Shrox's rockets...along with a bit of shameless self-promotion.

Are you going with the 24mm mount?

Yes, as that's what your plans call for. I did notice that the return on the "B" fins was a bit short of reaching the motor mount (after cutting them, of course!). I should have checked this before gluing up the main fins but I think I can remedy the problem by gluing on a narrow strip of wood and sanding to fit.

No problem for a Ninja like me.

Yesterday I glued small strips of basswood to each of the two wing fins and also the tail fin. I also built the 24 mm motor mount, using BT50 tubing and home made centering rings of 3/32" aircraft plywood. Today I test fitted these parts and now everything fits as it should. I am awaiting a PNC 80 nose cone and a shock cord assembly that I ordered from a guy on Ebay and will continue this build when they arrive.

This morning I also pulled sand stickers and mowed the lawn. As it was cool and cloudy most of today, I fired up the John Deere 950 this afternoon and finished demolishing the barn/outbuilding which was destroyed by last December's ice storm. Now I'm cooking salmon for me and my lovely bride.

So much for my day of rest.

After doctor's appointments, grocery shopping, building fin jig parts, lawn mowing and repairing all of the junk that goes along with it, I finally returned to this project. Macklin's rendition of the Skonk Wulf by Shrox is almost finished...except for the launch lug, painting, decals and flight prep. I should be 100% by Christmas. Maybe?

I deviated somewhat from the sequence shown in the plans and instead chose to mark and fabricate the fins first, as this would give the glue plenty of time to set while I worked on other aspects of the build. Next I fabricated the centering rings and made a 24 mm motor mount. Since I didn't have an Estes E size motor hook on hand, I used a standard hook for A-D motors, but installed with the hooks pointing outward using epoxy and fiberglass strapping tape. When I fly this exotic creation (if I get the nerve), I'll make a masking tape thrust ring on the motor and then retain the motor with a couple passes of masking tape.

It took a bit of improvisation to use my fin jig to set the "underfin", because the distance between the bottom of the aluminum alignment rails and the point of tangent on a BT80 is only about one inch, barely enough to capture the work piece. To solve this problem, I gauged the rails further apart by use of two 1/8" x 1" aluminum flats and two 1/8" x 2" x 2" angles which were set within the rails and sandwiched the fin. This allowed the fin to be adequately held while being glued. (See pics)

All in all I am very pleased with this kit and the way it is turning out. Were there things I would do differently were I to build it again? Sure. Aren't there always?

Here's some more pics.
