Axle that goes 90 degrees

[Bbafett]

I have a moc, designed by someone else, that I am building that has an axle coming out the side at the bottom to open/close the wings. However it is in a very difficult place to reach was wanting to turn the axle and have it come closer to the back 90 degrees so it is simpler to reach. 

It is a regular long axle.  Struggling on what is the best way to modify it with it hanging out with nothing below it  Any ideas?

There is a hinged axle joiner, but you are probably better off using a pair of gears at 90 degrees.

Do you know the part number?

It might be easier to use knob wheel on both axles

[Bbafett]

That is a good idea.

And this is a LEGO original idea, as they used it in Mindstorms NXT 2.0 (I believe in the ball sorter).  This is good confirmation to an idea that LEGO has used the same technique, verifying the stability.  I lost one of the knob wheels from my Mindstorms NXT 2.0 and replaced them with bevel gears until I could acquire a replacement, but the connection was not as stable as with the knob wheels.  LEGO pieces allow more motion play than on metal gear mechanisms, so gears as small as the bevel gears can strip out and skip connection fairly easily.

Knob gears are good for what they are designed for - transfer high torque at lower revolutions. However they produce significant friction and would wear at higher speeds. In such case bevel gears would be a better solution. But as always, every implementation depends on lots of factors.

LEGO gears are known to require proper bracing (both ends of an axle should be placed firmly in a structure), otherwise at greater torque they would slip and produce this grinding noise.

I agree completely with this.

Hopefully @Bbafett has the answer needed now for what transmission type is needed?
