Why do you think another one is necessary ?

Oh man - now I'm also blind and can't see that you have already made (and mounted) them both  :facepalm2:

Achim - I hope nothing serious is keeping you away from here and that you are doing well ...!

Hi Per, thanks for asking.
No, nothing really serious is the reason.
Only the stress of a retiered person
The shop, some intensive sailing during summer time at the local lake  and a in February started consalting self employment does eat the time.
Impossible to understand how I have found the time to go to work in the past.
The progress at the engine is still ongoing, but I have to catch up again, with the build report.
Never the less, that is where we are today.

Oh yes - I can see that you have been busy with the build too - Looks really good  :praise2:

Apparently it happens to ALL of us (with few Elves exceptions) that we slow down and have Absolytely No Clue how we found time earlier in Life  ::)   :old:   :noidea:

Oh well, have  :DrinkPint: and Enjoy ....

Thanks Per.


May be a good opportunity to go ahead with the build report.
What happens so far ?
The cam shaft is finished with all details for later adjustment.
The cylinder unit is done, so the 3D printed dummy is in the bin now.
The cylinder heads are half way through.
Pistons are done and the piston rings got something about 4,5 hours of slow driven movement at the "drag test bench" or better known as the lathe in this case.
A 3D printed drip pan was made.
And most of the parts so far, with the exception of the heads, has get the final surface, mostly powder coating.
During the reassembling near all temporary bolts, studs and nut has been replaced by the final "nice" type.
Let´s start with cam shaft and the tapper rod guide.
I think the pictures are self explaining.
The cam shaft has get some very small groove exactly at the circle where the set screws will clamp for timing adjustment.
So the burr of the set screw tip is not at the normal surface level of the shaft surface.
To be continued...
Kind Regards
Achim

Roger, Kim thanks for popping in.


Summer is gone here, it s foggy and most of the winter time garden preparation is done.
The progress of the build is still same as shown in the last video.
I start now with the build report up to that point.


The cylinder unit is a very special fabrication part.
The two cylinder will soldered together by a spacer between.
A fixture was recommended by Doug Kelley for this job and as later confirmed, very useful.
Some steel plates has to be prepared and at the end it look like shown in the pictures below.
For some general check, I have used my 3D  printed dummy cylinder.

Hi everybody.
And now the first cylinder itself, the usual process at the late with drilling, turning and honing operation.

This is not the liner, its the outer part of the water jacket.
Liners will done later.
The honing was done only to get familiar with the process again.
Something special, an O-ring grove at the lower end.
I have made a dummy liner for checking the bore over the entire length.
The size of the bore does have still a bit overstock, because a final machining of both bores will be done after the soldering.
The drawing does show the internal and external necessary machining and the cylinder.
To keep everything in position during the soldering, some pins are located between the two cylinders and the spacer.
The plate/frame was done already in spring time, when I made other plates with my self made vacuum table at the CNC mill.
Also her are three pins located, with the only function to keep all in position during soldering.
The two cylinder and the spacer will be silver soldered in the fixture, the legs also.
The plate and the water outlet will be done by later soft soldering.

Here are the pictures of making all the additional part for the unit, mostly made by CNC milling.

Will you soft solder the additional parts in one operation? A nice piece of fabrication  :ThumbsUp:  :ThumbsUp:  :wine1:

Finally the M1,6  thread has be made by the computer in the water outlet again.
Still today, I am not able to watch the tool, if it dives first time into the hole.
I press the start button at the CNC mill and are looking out of the window, waiting a cracking nose.



For the brazing I have started a new journey.
During my last purchase of silver solder at my preferred supplier, I have seen the offer of "brazing foil".
This foil is the same material as my usually used bar, but is available in stripes of 0,2 x 20 mm and I could by a length of 200 mm there.
Target was to use it for the spacer and the legs in this case.
Kind Regards
Achim

Hi Roger, good morning.
It was scheduled to do it step by step.
First the plate/frame and second the water outlet.

Before I ruin all the nicely done parts, my idea was to do a test brazing.
I have had some spare stripes after all was prepared for the cylinder unit.
So a test soldering could be done as shown in the pictures below
No extra fixation, only laid flat at a heat resistant stone and heated up to nearly 700° C.
It is a lot of solder visible flowing around, so I should take this into account, if I do my real part.
Encouraged by this experiment, I have started the real job.
