NiteSeer | 05-Jul-10 03:24 | Incredible job of covering! |
scigs30 | 05-Jul-10 07:01 | Well, I woke up this am and noticed the stress wrinkles on the wing have increased, so I decided to remove the covering from the wings. Trust me this is pretty easy to do since I cover with diluted white glue. I first cut the tissue away then brush water over the attached tissue. I have to let this soak in through the 2 coats of dope, but when it reaches the glue, the tissue releases super easy. Now I am going to add a little brace at the root rib then pre shrink the tissue twice and re cover the wing. |
pakasit1812 | 05-Jul-10 13:32 | Please, let me learn from you scigs.What is the advantage of pre-shrunk tissue and how do you pre-shrink it? Correct me if I am wrong. The pre-shrunk tissue will not have no room to shrink anymore when applied on surface. |
scigs30 | 05-Jul-10 16:35 | I only pre shrink Japanese/Esaki tissue and not domestic tissue, since Japanese tissue shrinks a lot. I have an old wooden picture frame the size of a sheet of Japanese tissue. I brush my thinned out glue mixture on the frame then attach the tissue. When the glue is dry, I mist the tissue with water or alcohol. The tissue will tighten up but there is still pretty good shrinking left. Normally if the structure is strong, I only pre shrink it once, but if the structure is light and fragile, then I will spray some more water on the tissue to shrink it again. |
pakasit1812 | 06-Jul-10 02:40 | Thanks,now I understand how you pre shrink Esaki tissue.
A little bit more on the subject, what would be the difference of the end results between pre shrunk and non
pre shrunk? Does Esaki shrink too much if applied
straight on the airframe thus it warps the frame? I've no experience on Esaki. Thanks in advance,scigs |
scigs30 | 07-Jul-10 09:09 | If the frame is light weight, the non pre shrunk tissue will cause warps and stress wrinkles by pulling on the light structure. Pre Shrunk tissue decreases the chance of that happening. |
pakasit1812 | 07-Jul-10 12:36 | That's clear, scigs. Thank you very much, my friend. |
