Eccentric cam wing assembly tools

Dan- The only problem with that is the bolthead would try to unscrew if turned counterclockwise. Schempp-Hirth provided a rigging tool with the Arcus that has an allen head bolt inset in the face of the tool and we ran into that issue.

If you only turn it clockwise, it isn't a problem. I might incorporate that idea if people request it.

Sorry, I should have been more clear, I didn't mean to use a threaded bolt per say. I agree it would have to be a "solid" installation that could be turned either way and not unscrew.
It would be a nice option. It's a great tool.
Good luck,
Dan

glue the bolt into the threads.

Should it take that much effort to require a ratchet?
For a Schleicher, the hex key used for the tail works in the holes of the Bralla/MM or Cobra wing alignment tools. Sometimes turning the tool by hand is sufficient.
The dump handle should be in the closed position. From experience, ASW27/G29 is more difficult with the valve handle in the open position. Using excess force with a Schempp dump valve misalignment may end in tears.

Oh dear, how do we know this???

Someone gave rigging in "dump" position a try on one of the club's Discus 2s.
Seems like a wing panel makes a good hammer.

Nope. The best way to incorporate a hex head is to drill an undersized pilot hole in the tool end. Then press in a length of hex bar stock that has a bevel ground onto the end so it won't "shave" the Delrin as it is forced in with a press. The Delrin will "flow" enough and lock the hex in place.

Note I did not incorporate the above on the tool I made as I considered a hex wrench to be too "fiddly" to reverse direction. In use, there are times when the eccentric tool wants to be moved back and forth and the ratchet wrench is near hopeless for this. I (of course!) think my design with the three cross holes is functionally better. The 1/2" stainless steel handle rod is bent at it's center, the bend is such that it splits the angle between the three cross holes that provide 6 handle positions - so with the bent handle there are 12 discrete firm positions, the bend also acts as a handle "stop" when inserting the handle, as designed, it works flawlessly (and I'm not one known for leaving well enough alone - sigh .
