Nigel Heather Posted February 21, 2023 Share Posted February 21, 2023 What do you use for lightweight tubes in built-up wings for wing-servo leads? In the past I’ve used rolled up paper but wondering if there is something a bit more substantial but also light weight. Quote Link to comment Share on other sites More sharing options...
Geoff S Posted February 22, 2023 Share Posted February 22, 2023 Tubes made from papier mache? ie rolled up newspaper well wetted with white glue - still light but more substantial and still cheap. 1 Quote Link to comment Share on other sites More sharing options...
Don Fry Posted February 22, 2023 Share Posted February 22, 2023 I spray paper tubes with shellac, varnish, if they need it. But normally a paper tube is fine. One point, paper does exist in heavier and tougher than the standard 90gsm stuff. Mick Reeves Models does 0.2mm epoxy glass sheet, ProSkin. It will roll into tubes. I once made a wing, used a proskin tube for the main spar, and passed the servo wires through it. All jobs done. Be aware, varnished rubes and epoxy sheet are sharp. Don’t get a cut wire. 1 Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted February 22, 2023 Share Posted February 22, 2023 Me too, rolled paper and wood glue. 1 Quote Link to comment Share on other sites More sharing options...

Don Fry Posted February 22, 2023 Share Posted February 22, 2023 Nigel, don’t know about High Street presence, but still going as a internet company. I believe Mick’s son does the manufacture nowadays. ProSkin is still available. Useful stuff for all sorts of jobs. I think it’s from the USA, used in electronics, so there might be alternative sources. Quote Link to comment Share on other sites More sharing options...

extra slim Posted February 22, 2023 Share Posted February 22, 2023 depends on size, but drinking straws are handy in that situation, and you can get quite long ones, paper or plastic Quote Link to comment Share on other sites More sharing options...
jrman Posted February 22, 2023 Share Posted February 22, 2023 Supermarket cake icing and marzipan are rolled on a very lightweight plastic tube about 20mm dia. Perfect for servo leads, you just need to get your "pinny" out and start baking!😉 Quote Link to comment Share on other sites More sharing options...
Mike T Posted February 22, 2023 Share Posted February 22, 2023 Rolled paper, tacked in place with cyano. Or large-bore plastic drinking straws*. These tubes don't carry any loads, so gooping them up just adds weight. *bought in the days when you could get them. I assume 'green' equivalents are now available!

Martin McIntosh Posted February 22, 2023 Share Posted February 22, 2023 Why on earth do you want to put leads in tubes? Just run them through holes in the ribs which saves removing and refitting plugs. Quote Link to comment Share on other sites More sharing options...
Don Fry Posted February 22, 2023 Share Posted February 22, 2023 Because some folk prefer to protect the wiring from being flopped about in what is a series of wire stressors. You need to imagine a tube bigger than the plug, so no need to remove the plug. 1 Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted February 22, 2023 Share Posted February 22, 2023 So in a tube that large it will still flop about will it not? Quote Link to comment Share on other sites More sharing options...
Nigel Heather Posted February 22, 2023 Author Share Posted February 22, 2023 For me it is because it makes it easier to thread the servo lead through. Cheers, Nigel Quote Link to comment Share on other sites More sharing options...
Mike Blandford Posted February 22, 2023 Share Posted February 22, 2023 I've used rectangular tubes made from 1/32" balsa. Mike Quote Link to comment Share on other sites More sharing options...
