More power to your elbow sir, keep the pics and work comming, on the sheet repaire i have succesfully used the following method before.

Cut out a section of balsa of simmilar thickness oversize to the repaire area required, stick this over the hole with selotape sticky back plastic if you like and then cut out the required section through the stuck on piece and the section to be reparied at an angle of 45 deg to the horizontal in towards the repaire area, this gives a slightly oversize repaire patch and a greater surface area to stick the patch too once trimmed.

Shame you have not got the nose pices that broke on the landing! as if you glue them all back together you have your own template, this is what I plan to do with mine when I repair it, you never know you may give me the incentive to get on with it.
Will look regullarly for progress.
