Olly P Posted April 2, 2012 Share Posted April 2, 2012 Hi all, The other week, my better half dragged me to a fabic shop with her. All was no lost however, as I had been thinking about making a sanding tool to do the job I like least on wings - shaping the leading edge. I find it very hard to get a consistant and smooth 'roundness' to them when I'm sanding and have been strongly tempted by the permagrit tools, but put off by the price. Anyway I spotted the rolls that had been emptied of fabric leaning in a corner, and asked one of the assistants what they do with them, apparently some are reused, and the ones which have been bashed on the ends go for recyling. anyway I asked for a couple of the 'bashed ones' and got 2 in different diameters anout 3m long. These tubes are hollow and made of a cardboard like fiberous material. I intend to cut them shorter, probably about 12" long, and then cut in half, soak in watered down PVA and attach some sandpaper to the inside. These should then do a large amount of the sanding smooth and evenly for me. I can also cut some smaller radii to allow me to sand and different angles!

andy watson Posted April 2, 2012 Share Posted April 2, 2012 An excellent idea- but it reminds me of an urban myth I heard at school which was about a bloke who wrote to Swan Vestas (the match company) and offered to save them £X million per year with a simple idea, in return for half the first years savings. Allegedly the company agreed and he told them to only put sandpaper on 1 side of the matchbox- halving their sandpaper costs- and our hero trousered a fortune! I would also suggest sticking sandpaper on the outside curve too- then you can also sand those internal corners and curves with the same tool.

kc Posted April 2, 2012 Share Posted April 2, 2012 The cardboard might straighten out if cut open, especially if soaked in a water based glue! Try a piece of scrap PVC plumbing pipe. The cardboard would be better kept to store rolled up plans or several lengths glued together to store balsa strips etc. Quote Link to comment Share on other sites More sharing options...
Olly P Posted April 2, 2012 Author Share Posted April 2, 2012 kc - it isn't capboard per say - it has that consistantcy, but is almost a fibre board! Given the length I may keep the smaller diameter for carbon rod and piano wire storage.... Olly Quote Link to comment Share on other sites More sharing options...
