Stephen's modular cockpit needed a dual throttle. (Actually, I'd like to fly planes instead of helicopters, so I decided to build a set of throttles for Stephens cockpit)
This is a really quick try at dual throttles, as simple as possible, made from parts we had laying around.
Basic ingredients: wood, PVC pipe, bread cutting board, M3 and M4 screws and nuts, woodscrews, hot glue, 2 pots, L-shaped aluminum profile, black PCV part used for carpets, wood glue, and some wires.
Here are the two handles made from PVC pipe, with wires prepared for the AT-disengage buttons.
The white part is attached to the black with hot glue in addition to a woodscrew that has been glued in. (visible in picture #9)
the white bread cutting board piece is attached via an M3 screw and has a 4mm hole for the pot
The black levers are "doubled" on the upper part of the levers as seen here at the right side.
Bread cutting board detail. The 4mm hole is the pivot point.
Mounting to a base board. Both pots mounted on L-shape alu brackets.
A long piece of bread cutting board goes in the middle between both levers. I cut off the head of a M4 screw and stuck it into that long piece. This, in addition to the pots, is the pivot point and holds the levers in place.
I coupled the pot to the lever via the small bread cutting board piece, then stuck the M4 "be-headed" screw with the long piece of bread cutting board through on the other side of the hole...
... and the same thing with the other lever...
push it together and mount the L-shape alu brackets to the wooden board...
et voila... we have the basic two engine throttle finshed...
Now it'd be nice to have a little more friction...
Not the best approach, but it works: Use more bread cutting board to push against the smaller pieces on the levers.
Therefore we need to build a support as seen here. Just some wooden pieces screwed on the base...
... and two more to get to the right height. Using two long thin pieces of bread cutting board and some wood glue (white here, still drying) I have a basic friction lock.
However, this approach has one disadvantage: If the two levers are not at the same postion, the friction lock is much weaker and pushes the levers slightly across the middle line between both levers.
Here the finished piece.
