You may need to get your eyes checked and get some new glasses.... :poke: :lol:


Sometimes looking at things in 3D creates an optical illusion...

Luckily I had a crank in my room right next to me when I drew it, so I made sure that I have the journals in the proper orientation...


I did do basic shapes and fudged some of the counterweights because as Chris can account for, the sketch for the details must be what's called "fully defined" for you to go to 3D or it can cause issues later... With some of the complex geometry in the counter weights, it can be difficult to get the sketches to be fully defined so I can extrude them into 3D details... The main purpose of the final project is to get the parts to assemble in 3D and move correctly, so a few scallops in the details is not as necessary as getting the parts to fit and move correctly....

Yes, any part that has high loads should be made out of strong materials... I don't think they have any 3D printing materials that can handle heavy loads yet...

The hard part of reverse engineering is to figure out how large some of the radiuses are... I don't have any measuring instruments that can do that accurately....

When I was at the engine plant, we had a CMM and another machine that you could make a shadow of the part and magnify it to measure it more accurately...

Curves and radiuses are hard to measure accurately with a hand caliper... :BangHead:
