Default warped fuselage solution..

on my 1st Tiger 60 kit, the fuse sides were warped and the resulting fuselage came out with a crooked front end.
I packed it up and returned the fuse to Carl Goldburg and they promptly sent another kit to me. This kit had the exact same bow in the fuse sides as the first kit.
Following the instructions of using rubber bands to assemble the fuselage and then applying glue to the seems wasnt going to pull the fuselage straight.
SOOO after much staring at the situation I came up with something that gave me a reasonably straight fuselage.

I cut out a 1/4" hardwood template of the front of the fuselage. This template matched the inside shape of the fuse.
I could see that by putting this form into the fuse and clamping from the outside it pulled the sides into alignment with the back half of the fuse.
(the back half of the fuse has enough parts that fit together that it does pull itself into alignment. My problem is from the back of the wing saddle forward.)
I then cut this template into sections to fit around the bulkhead pieces. I also cut the section in the wing are in two so I could still remove it after the fuse was glued up.

By clamping the template into the fuse everything is held in alignment while I add the glue. (actually, I applied the titebond glue and THEN clamped everything up)

It seemed to work well. when I pick up the fuse from the rear and sight down the sides the front is symetrical, Much better than the first attempt.

I'm glad Carl Goldburg replaced the kit but I'm not happy with the quality.. The instructions are poor.
If I see another tiger kit at the field you can be shure I'll be looking at the nose of it to see if its crooked!
I'll be interested in seeing how my next kit goes together. It wont be a goldburg kit...
