Tips for Bending Landing gear for Smoothe

Would love to hear how others have done this. I snapped mine tonight, so I am done building. I was using a 4" shop vise to hold it and pushing slowly on it.

Thanks

I use a mini torch to anneal the spot where i am going to make the bend. You can only bend it once, not back and forth, so plan ahead. Hope this helps

I use a K&S wire bender. Higley also makes one.

buzzbee,

Email me your address and I'll send you some more wire.

I just use pliers to bend mine. I've been using this type of gear for a while so I'm pretty used to doing it.

I used a vise and a brute force to bend wire up to 5/32". When it comes to making the bend sharp, you bend it by hand to shape and then pound the joint with a hammer on the vice jaw to make it a perfect 90.

Here is a pix of the MFG gear and my stiffer replacement in 5/32" wire. just take your time and be picky on the angles. Match the precisely as you go.

i curse a lot when bending mine - it doesnt help much, but i do feel better. if the mountain models planes werent so damn good i wouldnt bother with it once you fly it, you will forget about the trouble of bending the wires.

i think next time i will send a few extra bucks and just have doug bend them for me

I think cursing does help. It shows that inanimate object who is boss. I have a few choice words I save for hitting my thumb with a hammer as well.

I subscribe to the "Beat with a hammer" school of thought as well.
Here's my "technique":
1. Mark the center point with a Sharpie
2. Stick it in a vise so the mark is just barely above the jaws
3. Hammer a 90 angle into it, take it out, beat the remaining 20 (or until it lines up with the landing gear mount)
4. Measure & mark " in from the ends
5. Stick it back in the vise (again, with the mark just barely above the jaws) and hammer about 55 into it for the wheels.

I haven't snapped or have had to redo anything using this method, and it takes all of five minutes.

Here's a story for you: A friend of mine built a Dandy, and he was telling me what a pain it was to bend the Tail wire. Granted, there are some complex angles, but nothing outrageous. I told him to bring it over and I'd finish bending it for him. It turns out he was using the main landing gear wire! I've never before or since seen such a beefy tail wire

Good luck and have fun with it!

I'd almost pay someone to do it, if there was anybody local to do it.

I've learned that close is good enough. My gear never match the plans (or each other) exactly, but you can't tell once they're on the plane. They are working just fine so I figure if it ain't broke don't fix it.

as a matter of fact, i think doug should revise the build manual to include cursing as part of the step - just to help everyone out

along with a picture showing the placement of the small brace (affectionately known as the 'Jeff" brace that goes in the middle of the sport wing - between the plywood)...and not just because i forgot to put it in... err i mean just because i wanted to save weight on my plane

Hmm, I could do that, Nose First...any choice of language the cursing should appear in?? ASCII (@#!!@*&$#)? Yiddish (OY VEYH!!)?

I used to curse. But then I bought a wire bender from Micro Mark. I curse no more.
