Ok, so I signed up a little while ago, and have been more or less just lurking about since. It seems I can find answers to any questions I have just by doing a search. But, I have noticed mention about button bellcranks quite a few times, and I think I've figured out the basic concept, you don't use lead outs, instead, the control lines are connected directly to the bell crank with a "loop and button" arrangement. So, my question is, how do you guys go about making the "buttons" and determining the loop size on the control lines?  Huh...  Thank you in advance.

I use button bell cranks all the time. I make my own buttons out of brass on a lathe but I used to do so by using 4-40 blind nuts turned upside down. I would chuck up the blind nut on a screw in the drill press using a jam nut against it and file off the nubs that crush into the wood. Use small screws through the bottom of the bellcrank into the upside down blind nut . Solder or use loc-tite on the assembly. Another method is to use a eyelet for your loop and use a screw and washer to hold it to the bellcrank. I can provide pictures of some if you would like for clarification. Nothing special about making the lines other than when you terminate steel lines, make a double loop when making line sets under .018" vs a single. Spectra lines only need one loop.

Thanks Ken, sounds simple enough, I guess I was over complicating things in my mind.
