Wedekind Sleeve Source?

Installing Wedekinds requires taking the couplings off the control rods (at least on the gliders I've done) so you either have to work out a way to measure the rod end adjustment before taking them apart and a way to ensure that you have them adjusted exactly the same after reassembly. Alternately you need to check the rigging of the control surfaces and adjust them to the proper deflections when you get it all back together. I know someone who put Wedekinds in his ASW-20 and spent a few years mucking around with the control adjustments because the glider kept rolling whenever he moved the flap lever. Eventually a mechanic in the club convinced him to let him use a digital protractor to set everything to factory spec and it flew perfectly afterwards.

The safety pins, especially if they're the captive type or tethered to the rods aren't that bad to deal with if you have a ship where the connections are easy to reach and see but with a 200/202/400 the Wedekinds are a real blessing.
