Andrew Winkworth gave me 3 x CS-127 blanks, and they all match perfectly, so it makes sense to try and make another to match rather than buy a CG one. I trial bent one of them using hardwood blocks in a vise, and it matches the diagram nicely. Cut another blank from 0.032" 2024 T3. Drilled and reamed the holes to match the blanks. Note that the stop bolt location needs to mirror the one on the other side of the bellcrank, so triple check before bending them all, and am pleased with the result. I just saved US$30!
And thanks Andrew!
Decide the bellcranks look good too, so will buy the bearings.
Discover I have 50 clickbonds, enough for all the jobs I can think of for them so far. Got them at Oshkosh 2010 from JD. Infinitys forever!
