Thanks! It was indeed one of my most productive Hobby Days. I'm really fired up to keep going this week too. Hopefully I'll get a lot more done at home as well.

I am so glad I subscribed to your topic; incredible experience to be on the wild ride you are taking through aircraft, armor and vehicle builds, Duke!!!
Thanks Bruce! This is one of my most exciting trips through the manufacturing plant, I should have more going soon.

1. For cementing aircraft fuselage seams, do you work from the center outwards or from both sides in when you add glue? I think I cocked up on the Horten nose by choosing a centered glue position than I had to add CA per Stik & Mustang & your suggestions. Is there a rule of thumb? This is the kind of basic construction question that does not ever seem to receive an answer or maybe it is so obvious it is silly to ask, but I am gonna ask you!
On a model like the F-102 or F-106 where there is a substantial opening under the fuselage for the wing assembly to fit; I'll cement the nose and tail areas first where there is more reinforcement to use to hold the parts together. Later on, I can add the thin cement to the upper spine area and press the top together while holding each side of the fuselage at the opening below.
On most other models, I'll add a slow-setting cement (like Testor's Tube Glue) to the entire edge of the fuselage and gradually press it together from nose to tail, lining it up as I go. If two fuselage halves are warped, I'll add glue to one end and press it together there until the glue dries. Then I'll add glue to another section and then press it together; slowly making my way down the fuselage, allowing the glue to dry before moving to the next section. It is a bit difficult to explain in text; when yo come to Hobby Day in June, remind me to bring something I can demonstrate these techniques for you.
Actually, Mr, Surfacer is a moderately fast drying product. The more you put on, the slower it dries. The heavy application you saw there took about a day to dry properly. You can also apply it in layers and let it dry in between, that will allow it to set much quicker so you can work it sooner. I even had to carve some of that thick stuff off since I'd applied it too thick. That's okay because I got the results I wanted; it's better too much than too little.speedgraflex wrote:2. Now I understand Mr. Surfacer better! Thank you. Question is how do you build layers if it is a quick drying product? My first CA attempts were pitiful and I ended up breaking parts because I could not grasp the timing at first, lol!!
I rarely use CA glue anymore to fill gaps unless they are quite wide. It can be a challenge to sand that stuff. Mr. Surfacer has effectively replaced CA glue for me for filling light to moderate seams and gaps.
Thanks again for the great replies. Stay tuned for more.
