I tell my wife that all the time about the "Clean Shop problem". I would like to see Strasburg's shop in person. I've spent time at New Hope and Ivyland's shop in New Hope PA. They have typical shop machinery, but if they need drivers turned they send them to Strasburg (as does the Union Pacific RR)
We're heading to the airport in an hour, but the printer worked overnight and produced the turbo, pump face and the heads/induction piping. Turbo and pump face are perfect. Induction piping is very good too. Heads are good, but the fuel lines are just too fine to print and the push rod tubes took a beating when I was cutting off all the supports (Lots of supports!). The pushrod tubes are just about 32 thou so I'm going to replace them with brass rod of the same diameter. Shouldn't be difficult since it is accessible by the drill. Fuel lines are a non-starter. No matter what I want to use, they're too small to manipulate. Some things should be left to people's imagination.
In the image you can see just a few fuel lines. They're so fine that the support overwhelms them. Just the shock of the flush cutter was sufficient to destroy them. You can also see that each push rod has one or more supports and the same effect occurred. Shock of cutting broke them. This was before secondary hardening. You can see how nice the front and turbo look.
The left side after cleaning looks good. I will carefully fill the couple of fractured spots with Bondic. I tried the induction system and it fit the supports perfect. What you draw is what you get!
After removing the supports, but before fine cleaning here some more views. Lost a lot of pushrods. I'll replace them all. If you look closely, the stud bolts at the head's corners are actually separate from the head proper.
The induction side came out well and the turbo lines up with it perfectly. No warpage. All those bumps will be removed.
Pump face is great! The check valve didn't print quite right. The output shaft splines printed! The fuel line from the fuel filter printed since it was supported well on both ends. I have to check the check valve drawing since that one of the few parts downloaded from the SketchUp 3D Warehouse and it may have some errors.
