Kozmyk Posted February 17, 2011 Share Posted February 17, 2011 Posted by Biggles' Elder Brother - Moderator on 16/02/2011 16:11:01:Have you tried it yet though Kozmyk? Most people find it wrecks the die! BEB Actually you are right. I've only tried it on SS and galv rod so far. Works fine on those rods but I can see that the tempering on actual piano wire could cause problems. The tempering also used to make it difficult to bend to 90° in the old days.

Alan Cantwell Posted February 17, 2011 Share Posted February 17, 2011 Tom i would expect no problems with SS in a model like the decathlon, its a gentle aerobatic machine, but i tend to fly high powered aerobats (well, i did) and these would break in a high G situation with SS, Quote Link to comment Share on other sites More sharing options...
Tom Wright 2 Posted February 17, 2011 Share Posted February 17, 2011 Gosh Allan what sort of control surface loads are we talking about here ? Quote Link to comment Share on other sites More sharing options...
Alan Cantwell Posted February 17, 2011 Share Posted February 17, 2011 aerobats with zenoah 62s in them, right up to 40% scale, with DA150s, but, i still would not use stainless for even my zenaoh 38 powered models, it just does not have the tensile strengh of hi carbon mild steel Quote Link to comment Share on other sites More sharing options...
thomas oliver 1 Posted February 27, 2011 Share Posted February 27, 2011 I have used cycle spokes in the past, instead of piano wire. These can be obtained in 16swg ( 1/16th in)< 14swg, 12swg, and 10swg( 1/8th in). Spoke material is especially formulated for thread rolling and is tougher and stronger than mild steel and can be bent easily without fracture. It cuts nicely with dies without blunting them. Another source is the use of the wire, which is similar to spokes. TUO Quote Link to comment Share on other sites More sharing options...
Alan Cantwell Posted February 27, 2011 Share Posted February 27, 2011 bike spokes are made to the thread roll size, try to cut a 2 mm thread, and most of it will be missing, but, thinking about it, motor bikes are another size up, wonder what thread they are?
