Thanks for following and the recognition. I spent most of the day today drawing more details into the 567. I've got the basic block in good shape for printing and I've finished fully detailing 1/2 of the head area of one cylinder back. The details are comprehensive, but not 100% accurate. All of the stuff is there: Injectors, injector rocker, four exhaust valves per power pack, Valve bridge rocker and rockers, rocker shafts and supports, cam shaft and supports, injector rack, head to sleeve bolts and power pack clamps and bolts. I then shrunk it down .021% to make it O'scale. SketchUp doesn't like very detailed drawings in small sizes and it crashed a number of times. I finally was able to export it an .STL, and then into the slicer and it did slice. I put it onto the thumb drive and was going to take it down to the shop and print it, but my wife suggested maybe not such a good idea since we're experiencing thunder storms and the power skipped a while ago. I can wait
I redrew the valve covers and put a lip on the open one to give it some gluing surface. I'm going to print the open one as a separate object. The heads will also be a separate print. I mentioned this before that I'm going to treat this almost as a model with separate pieces helping to reduce the print failure potential. As I gain more confidence in the process, I'll print more comprehensive models. The printed details will be a lot crisper than this PNG screen print. All that's functionally missing are the fuel lines.
I hollowed out the block a lot so it will use less resin and drain well. With resin printing you need a way to get rid of uncured resin. I opened four cylinders to key into the power pack heads of the four that I've detailed.
Next I'm working on the front and read accessory drives. The front one is is just a serious of cylindrical objects and connecting stuff, but the rear has the two Roots blowers and I'm going to have learn how to draw the waffled surface detail. I put a question on the SU Forum and see if they can get me started. The other complication is the soft curves in the air transfer manifolds. SketchUp is not particularly happy with soft curves. You can do it, but it's not one of my strong suits.
