Hi John, thanks for visiting and the friendly comment.

Next job the coating of the cylinder.
So some more parts for the masking are necessary.

Finally a first draft of the further cooling system.
The cylindrical body, pending there free in space should simulate a possible position of a fuel cell.
Kind Regards
Achim

cnr6400, Don and Kirk thanks for watching and the friendly comments.


Kirk, good luck for your first coating attempts.


Now we do have the point for no excuses anymore.
The crank case has to be done.
Due to the, in my understanding nice press fit of the 2 crank shaft halves in the middle bearing, I want to avoid any disassembly of this unit.
A fixture to keep all cylinder in situ has been made for the disassembly.
Some more parts for a proper masking had been necessary.
Last picture, the crank case shorty before the total disassembly and cleaning for the tape masking.
Kind Regards
Achim

Nice progress Achim  :ThumbsUp:

Careful with those masking fixtures - I had the frame for my offroader back from powder coating and it has the oil tank integrated in the frame, so I used some purpose made 'stoppers' - and though they worked fine, the 'paint' had flowed nicely all over the frame and those stoppers -> the 'paint' broke a few places I really didn't want it to do while removing the stoppers. I did try to use a stanley knife around the stoppers to be the one that decides where the paint would break and it almost went to plan, but not quite.

If I should do that one again, I think I would use the same type of tape you use and wrap it around the stoppers  - though that still might give you a raised edge at those locations  :thinking:

I actually did powder coat my previous engine (Muncaster grasshopper), but I've seen some videos that make me think I can do a lot better.  Picking a color for the Greene is one problem as I have no idea how they were painted originally.  The one in Rhode Island has several coats of paint, none of which are likely original.  The one in Detroit is unpainted.

Hi everybody, next job was the masking of the big holes.
Some masking of the door frames and hinges.
Finally the masking of the lower case opening.
Coating, as always, was a 1,5 minutes job.
Getting rid of all this tape again and the reassembly could start.


Per, in the very first beginning of my powder coating experience, I have made the water pump for my snow engine with body and cover assembled.
It glued together, like using a good epoxy glue.
It took me hours and the usage of an hot air gun to split it again.
Since this experiences, I am always using a layer or two of the green tape at the split faces.

Knowing what is likely to go wrong, can be a very helpful knowledge and it looks like (and by explanation) you are well aware of the potential pitfalls - though getting that experience is usually not nice ....

Great result Achim - looks like you nailed it  :ThumbsUp:

Excellent  :praise2:  :praise2:  :wine1: Do you have an idea how thick the coating is, 0.05mm?
Best regards

Hi Roger thanks.
Some times ago I have tried to measure it.
Before and after and the result was something between 0,01 and 0,03 mm.

In the meantime the crank case is reassembled.
And also the service platform and the stairs are done.

Here a quick view around the engine.


Kind Regards
Achim
