Using Micro servos, need help with linkages/pushrods
 

OK... probably another naive question...

I'm trying to use a micro servo (Hitec HS-81) to move the lense on a camera. The problem I have is the holes in the servo arm and in the lever in the camera are too small to use standard size links.

I don't want to drill them out larger, there's precious little extra material around the hole, drilling it out, would weaken the material too much than I dare.

Are there "micro" size linkages???

I did a quick look on Tower and nothing jumped out at me...

A little help??


TIA

Actually, there is enough meat there to drill'em out for standard 2-56 clevis hardware. Not enough for 2-56 rod, tho. You can use lighter music wire pushrods with ezkeepers, or any of a whole bunch of other micro sized hardware. I've only done one 1/2a plane so far, and I used clevis hardware, no trouble!

Yes there is smaller linkages and clevases but JBURRY is right there is plenty of extra there to open the holes. What I do is heat a piece of scrap rod and push it threw that way your hole is just right.

If you are really concerned you can buy a set of standard servo arms if you don't have any laying around, and they do fit the HS81, I just put a standard 4 arm Futaba servo horn on a Hitec HS 81 and it fits like a glove.
