DIY RC Push Rods - super cheap - $0.03 each

- Опубліковано 29 гру 2016
- This is how I make my RC push for my scratch built airplanes, I use 18 gauge wire which I temper with a little propane torch to change the wire from flexibly to fairly stiff. This is a super economical way to make push rods. We could make 220 6" pushrods from a single pack of wire that costs about $7, which works out to each pushrod costing about three
cents. - Розваги
You can straighten it also by clamping in a vise and attach other end to a drill snd spin it. It will straighten right out.
Thanks sooo much buddy, this made my day :) got into rc planes recently and want to build my own. you just saved me alot of money
Happy to help, happy flying!
I had been using the marker flags you get from Home Depot but they rust. Will try this. Thanks!
Great idea Drew. Way to think out the box. Just subbed man :^)
Aero FPV , I apreciate that, you have any advice on inproving the quality of this type of content? I'm fairly new to production. cheers
Anything to help Drew. I'll keep those gears in my brain goin to see what I can come up with :^) But I do know flight review info is big on YT. Take a look at my friend Jeff's channel at 7demo7 for some great ideas.
just pass current thru it and it heats nice and evenly
This is something new for me dude. Thanks for sharing.
Greetings again Luqman, thanks for watching, I'm glad this video was helpful to someone!
THERES 18 GAGE … wire.. already been heat treated: home depot/ or lowes: made for tie rebar /before poor concrete!
Thanks, I clicked on this but do not like the idea of burning off galvanized wire... That stuff can kill your lungs.. Again Thank you.. I'm going to go look for them..
That red button will light the torch for you. 😁
it's easier to cut the pushrods to the final lenth fisrt and then apply heat to make them hard
I heard that cooling the wire in oil was supposed to help with the hardening process as well
cyclistpilot, not a bad idea, wonder what kind would be good to use. would be fun to run some stiffness tests
DrewMan RC oil wouldn't do anything with this but make a mess and a small flame
oil is used to quench (temper) metals because it has a much higher boiling temperature than water. When the red hot metal comes in contact with the water, a layer of vapor is created instantaneously, which will diminuish the heat transfer . Lower heat transfer, longer cooling time, which dificults the tempering process of the metal because it is necessary to cool the metal as quick as possible. With oil this doesn't happen so easily. On the other hand, the wire is so thin, that you can use water without losing hardness...
Wouldn't of thought there was enough carbon to harden , cool now I know . Thanks .
Spencer Boaz, I was fairly surprised as well, but hey, if it works it works :)
piano wire is cheep but the shipping kills ya . If HK's shipping was cheaper I would buy way more from them I look for free shipping on ebay .
Spencer Boaz buy from radicalrc for com... $3 U.S.A.shipping with 6 pieces of rod stock or more...music wire counts. Always in stock and cheap for .032 like $.55 for a straight 3 feet...
Could you maybe apply electricity to the wire to get instant red hot? Or not a good idea? Like a foam wire cutter.
Matt Jones , that might work, sounds a bit sketchy tho
That's true. I would just do it this way.
electricity, water, red hot wire, what could go wrong? why not just buy some piano wire at the hobby shop, it is pretty cheap. some of it even has threaded ends that fit quick links.
Matt your a smartie pants that would but this whole process down to a couple of seconds per wire. As long as you remember to turn off the power before you quench it.
I use paper clip
Is this wire's thickness is affordable to pass through the holes of servo 9g?
For the most part yes, although you may need to use a small drill bit to widen the servo arm holes just a bit.
@@DrewMann nobody give this information
Can I use candle instead of torch
maybe, not sure that it would get hot enough
I do it but it breaking after temper when i bend it
sorry, the wire will certainly become less flexible after tempering
@@DrewMann what is the solution
@@advancetech7479 you could try doing the bends in stages, heating between each bend perhaps?
reHeat the end you want to bend and let it cool slowly. This will remove most of the hardness/ temper. After you have the shape you want heat it again then dip it in water again to harden it.
Hope this helps.
