Ron Gray Posted March 13, 2021 Author Share Posted March 13, 2021 @McG 6969 Just done a quick check on Royal Mail and for 20m it would cost approx £7.00 for packing and postage. I will need to create the package to make absolutely sure but that figure shouldn't be too far out (also includes the cardboard postage tube!)

Ron Gray Posted March 13, 2021 Author Share Posted March 13, 2021 Sorry Chris, just looked again, my mistake it would be in the region of £10 Quote Link to comment Share on other sites More sharing options...

It does need a hot covering iron, I use a prolux digital version at 220degrees. This will attach and shrink the film, if there are still wrinkles I hit it with a hot air gun. Heat it until the wrinkles 'pop' out then get the heat off quickly or you will blow a hole in the film. Mike, I built this old Amigo 2 kit about 3 1/2 years ago. The wing is quite markedly undercambered. It's covered with tissue over (IIRC 35 micron) gloss laminating film. After film was in place & shrunk I covered it with damp tissue brushed down with shrinking dope (Thinned about 50%). When this was dry it was given a couple more coats of the thinned dope. The tissue has not pulled away from the film since covering. Re the high temperatures - I managed to get some bad wrinkles in the film on the sheet balsa root area of one wing so re-heated with a heat gun whilst smoothing with the iron. I hastily stopped when noticed that the wood was becoming scorched under the film. Although the scorched area of the wood was left visibly brown the film was completely undamaged & thankfully also smooth. Quote Link to comment Share on other sites More sharing options...

I think the real problem was that I was using a rather heavyweight tea bag paper, basically silkspan, that stuff really shrinks with water and shrinking dope. Managed to get away with it by putting weights on the tissue between the ribs and then re-doping along the rib lines. No problem with the film, it never became detatched from the ribs. Apparently laminating film can be tinted by boiling with "Rit" fabric dye, it then looks like the other transparent films. Both the glue and shrink need considerably more heat than boiling water so there's no glue set or shrinkage during dyeing. Haven't tried it though.

Ron Gray Posted March 14, 2021 Author Share Posted March 14, 2021 Having looked into the dyeing, there doesn’t seem to have been much success, that’s not to say that it won’t work though. Another experiment for another day. Quote Link to comment Share on other sites More sharing options...

Mike, I used heavyweight Modelspan but because of my colour scheme choice I covered from the spar to TE first then spar to LE using a single coat of thinned dope for each section. Subsequent coats of dope applied to both areas in one go. If I'd been using a single colour, I'd have applied the damp tissue as before but brushed the thinned dope along the LE,TE, tip, root edges then the spar & allowed that to partially dry before a brushing a first coat over the rest.

Mike Tomlin Posted March 15, 2021 Share Posted March 15, 2021 Thanks PatMc. My next build has an undercamber wing, I will be much more careful how I apply the tissue. Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted March 16, 2021 Author Share Posted March 16, 2021 A quick update, all film has been cut and folded and I’m just waiting for the padded envelopes to arrive, will post on here when they’re ready to ship but best guess is that you’ll get yours early next week. 1 1 Quote Link to comment Share on other sites More sharing options...
