    Crank is done but not good. I had problems with the second chuck on the mill turn and the part was scrap anyway. I did the other step on the dmu 50, went good but the part moved in the chuck...

    So, i will have to make some kind of jig or i'll will do it in 2 parts. Making it one part take LOTS of material too... 20190221_145400.jpeg 20190221_145941.jpeg 20190222_134214.jpeg 20190225_105139.jpeg

    Did you make it one piece included the counterweight? No wander it took a lot of material.
    I just finished mine and I am pleased with the fit of the bearings and the pinion, a precision that I have difficulty achieving reliably.

    So, i did the first step of the crank. I tried to do it one shot but i had vibration problems and i was not able to hold the part like i wanted to.

    This one is good, i have +0.001" on every diameter, will test fit with bearings as soon as i get them.

    I should do the second step and the counter weight today. 20190301_083014.jpeg

    Colming along well. Not so fast over here though. Made a nice mirror image cam ring. Will be handy if I want the engine to run backward.:eek:

    On the subject of rockers... some parts are easier to draw that to machine.
    I made 12 rockers ganged up side by side. 2 extra because on a part with 27,696 operations, orientations and tool change is easy to screw up at least two.

    I'm good at backward making, but then being dyslexic helps, it also makes me crazy when copying numbers~
