Falcon5,

Impressive job. In the first photo of what looks like the central lower area of the fuse I see what I think is one inch blue foam. Is that what you used? Also, what do you use to glue the foam pieces together? I've had good results with the white Gorilla glue.

Your craftsmanship is outstanding.

Cannot wait to hear how she flies.

Thanks,

Paul

High Paul,

Thanks,

Yep it's 1" blue foam. So far I used 3M-77 spray and it seems to work pretty good. Spray one peice, then the other, wait 5 minuets and press together. I found with curved joints the 3M-77 being a contact glue as soon as the peices touch their bonded so it made it easier for me. Is the white Gorilla glue a contact glue also?

Andy,

Cool. 1" blue foam is a good material. Your subject is awesome.

White Gorilla is not a contact glue. It's one of those expanding polyurethane type of glues. The Gorilla white is fast-drying - enough to handle the parts in about 20-30 minutes.

You have to get the knack of it - it takes some experimentation to figure out how much to use to get just the right amount of expansion to fill the joint. You have to wet the gluing area with water to get the best results as water acts as a catalyst (note however that it is not water-based - in fact, if you get it on your hands you have to wipe it off immediately to avoid stained fingers).

If you use too much glue and you have to wipe off the oozing excess with a paper towel as it cures - but you still get a good strong if not pretty joint.

It's very effective for gluing spars or hard points into roughly hogged channels in foam as it is strong and lightweight. I've had some luck with taping over the joint, but in general I wouldn't use it on the exterior where you are going for a nice finish. It can be sanded though so it's not a disaster if too much oozes out.

Other than all that, it's great stuff!

Good luck,

Paul

Great job, I flew about 130 hours in T-38s and can't say enough good things about this jet, it's so simple and elegant. Will follow your progress with great interest.
