How do I keep the tip of my iron clean when covering models with heat shrink material?
A6. I suggest that you clean with the solvent that you use for the adhesive that used in the covering process. Simply wipe the hot iron with the solvent. Acetone or cellulose are equally effective in cleaning the tip of the iron. Q7 Having water shrunk the tissue it has gone “tight as a drum” on all the flat sections such as the underside of the wing. However, on the more complex sections with compound curves I found it hard to get it tight. In some of these places the tissue still shows signs of slackness, even after water shrinking. Additionally there are some small “crows feet” wrinkles in corners where the top wing spar meets the ribs. Will the doping process generate sufficient additional shrinkage of the tissue to remove slight slackness and wrinkles? If not are there any steps I can take to rectify the problem prior to doping ? A7. Basically Esaki tissue will shrink once and once only. The dope will not add much if any extra shrinkage. Actually it is better that dope does not ke
