Hello friends,
I shared my experience before how to force a pylon to match the wing perfectly quite easy and quickly here:
https://airlinercafe.com/forums/topic/how-to-fit-a-pylon-to-a-wing-my-experience/
I’m preparing a special edition of JT9 engines for Eastern Express 747SP kit with pylons fitted to the wings from this kit.
I still applied my own method, but I found the materials that I consider ideal.
Pins become unnecessary.
Now I use CA putty.
It’s a very convenient thing!
It’s sticky enough to hold the pylons on it.
At the same time, you have plenty of time to turn the pylons in all directions.
As soon as the desired position of the pylon is found
a drop of hardener instantly freezes CA putty.
The main problem is to set the engines at the correct angles in 3 dimensions.
I do not know any trick for this 🙁
I do this by eye on the pre-assembled airframe.

I don’t always say “Proceed as requested”
But when I do, it is because I have no clue what you just said.January 14, 2025 at 1:58 pm #247183Ustar UA-90113 CA Putty

Sergey, maybe the time to align and adjust the piece is the biggest advantage, but I still have questions: Does it works better than baking soda? I mean, strength and hardness X ease of sanding….😬

If you live in a humid part of the country, the baking soda will eventually absorb enough moisture from the air and start leaking from the seams it’s been used as filler. Not right away, but after several years, your model will start foaming like a rabid dog. 🙂 Baking soda as a CA accelerant has been deprecated for several decades, but it keeps popping up as a filling solution.
