Brian Parker Posted June 28, 2008 Share Posted June 28, 2008 Paxolin is composite material similar to printed circuit board (PCB) material. Tufnol is also a similar material. Both can be machined.Just use a modern hinge material. Quote Link to comment Share on other sites More sharing options...
Chris Beer Posted June 28, 2008 Author Share Posted June 28, 2008 thankyou brian. looked at the plans again today , its paxolin horn not hinge, and it shows horn inside the aileron. Quote Link to comment Share on other sites More sharing options...
Alan Gorham_ Posted June 30, 2008 Share Posted June 30, 2008 Chris You can buy Paxolin in sheet form from your friendly local model shop. I think MacGregor industries distribute it and it comes in various thicknesses.Basically, your plan will show you the shape of the horn. You will have to transfer that shape to the sheet paxolin and cut it out - a fretsaw will work well. You will also have to drill the hole in the horn for the control linkage.I suggest you have a go as not only is it very satisfying, you will have learned a method of making control horns to suit any location as opposed to just buying a pcket and bolting then onto your model Have fun.

260 Flyer Posted June 30, 2008 Share Posted June 30, 2008 Or you can use a piece of birch ply and dope it with CA after shaping and drilling the holes. Quote Link to comment Share on other sites More sharing options...
Alan Gorham_ Posted June 30, 2008 Share Posted June 30, 2008 I still think paxolin would be stronger and less likely to split than birch ply - especially when most horns would require quite thin ply.I do agree that finding and then buying a piece of Paxolin is one extra bit to a building project, but I would still feel happier using it than ply for a reasonable sized model. I do know that my local model shop keep Paxolin so it shouldn't be a great hardship to find. Quote Link to comment Share on other sites More sharing options...

Alan Gorham_ Posted July 1, 2008 Share Posted July 1, 2008 Chris - if by Vero PCB you mean Veroboard that already has holes performated in it and has copper strips on the back - do NOT use it!! As Eric says, it is nowhere near as strong as either paxolin or "proper" FR-4 grade glass-epoxy board. It WILL crash your model for you!If you're stuck for paxolin - give me a pm and I'll send you some. let me know how much you need and what thickness....

Chris Beer Posted July 3, 2008 Author Share Posted July 3, 2008 thankyou repliees. ( is that a word? ). ill look for paxolin . the stuff i have is veroboard, my uncle was a sales rep. Quote Link to comment Share on other sites More sharing options...
Alan Gorham_ Posted July 3, 2008 Share Posted July 3, 2008 I said "performated" in my last post. An interesting combination of "perforated" and "preformed". Or just lousy typing....Chris, if you can't find paxolin (and bear in mind my offer to send you some if you're stuck) you may come across GRP sheet which will be at least as strong, if not stronger than paxolin, so you could substitute this material. Just get the same thickness sheet and you will be OK. Quote Link to comment Share on other sites More sharing options...
