Very nice Achim!

I hate seeing it coming to an end; but I'm sure you have another project waiting.

Hi Dave,
due to some special circumstances, I had to make a brake with the Snow engine, so we will have some more time to an end.

As mentioned in the Hoglet post already, I try to improve the clamping of the taper in the flywheel.
The machined taper in the cast iron flywheel has not the best surface quality, I have to speak with the guy who has made it.
So after disassembling the flywheel my idea was a kind of grinding or better lapping action to get rid of some friction between taper and flywheel.
The taper and a piece of 12 mm silver steel was quickly and temporary glued together with a 2 component epoxy glue.
My automotive valve grinding paste had to do the job.
At the moment everything seems to be fitted very well but with the wrong bolts, these at the flywheel in the lathe do have the wrong, to big, head.
I will let it like this for some days and will try to swap the bolts step by step without losing any tension hopefully later.
Another very good issue, the ground check from the ignition box to all spark plugs via the entire engine with most of the gaskets in was positive.
Kind Regards
Achim

Hi everybody, another bankholiday in Germany and the final tiling and some grouting is done, not my favourite job.
Always a big mess.

At least you're moving in the right direction Achim  :ThumbsUp:

Are you planning on a bit of "wear and tear" and other ways of getting some "patina" on those shiny tiles  ;)

Hopefully some splashing oil will do this.

Jim, Dave thank you very much.
The last grouting was finished this mornig.
Tomorrow hopefully will be the day, to get the pump, the flywheel, the fuel cell with rack and the water tank back in position.
Kind Regards
Achim

Hi everybody, all lip seals are in position now.
The engine is again driven by the e-motor for another 5 hours with the same power input and revs like before the disassembling.
As Doug Kelley recommended, I have made a pressure test unit to check the pressure under compression. This will be done next.
The short adapter was nice to fit without removing the fuel cell rack.
Unfortunately I have done the measurement without the inlet manifold in place, which has caused a collision with the housing of the pressure gage.
So a longer one was made and I will have to remove the fuel cell with its rack for the compression test.
An adjustable timing wheel is also prepared in the meantime.

Kind Regards
Achim

Hi Vince, me too.
But I think there it is still a piece of way to go.

Thanks Roger.

... may be "banging" my head against a wall, because it doesn`t work the way like expected.
The pressure test, with all valve cages in position, will give more information, hopefully next weekend.
Thanks Roger

Hi everybody.
Last weekend I have done the timing in accordance to the intructions of Doug Kelley.
I took the opportunity to catch a bit more of the driven motion in a video.

<a href="https://www.youtube.com/watch?v=W1OTz-MJgnY" target="_blank">http://www.youtube.com/watch?v=W1OTz-MJgnY</a>

If this thing will ever run, perhaps, nobody will see this beatiful smooth motion anymore.
