Hi everybody, here the last progress for the exhaust.
Soft soldering of tube and flange.
Some gaskets and everything in situ.
Now the coolant has to get out of the engine.
First part of the coolant return pipe made and pressure tested.
Kind Regards
Achim

Very nice progress Achim. On the solder your right to assume that the flux did in fact push the solder.  I have had that happen to me. I think if you would of tinned the part first before piecing it together you would of had solder there ready to flow with flux and heat then add as needed in some parts. With proper jig it could be done to insure the parts go together properly. Like Per said keep the heat moving and don’t let the part get too hot or the heavy area needing solder will flow out of the gaps. It hard to concentrate on both heatiing and adding soldering to the right amount sometimes with larger parts. Just my two cents.... You work is outstanding.

Hi Don, thanks.
You have remind me now, that there must be a little can with silver solder paste anywhere.
For the next time I will try to use this, may be only to get it tinned.
On the other side, with enough of this paste it may will work in this application also finally.
Another attempt, to get it work with less flux would sure also solve the problem.
Unfortunately here it was my last solder of an old  batch, still containing some Cadmium (the old stuff, not anymore allowed in Germany ) and I didn´t want to mix it with another new style silver solder.

Hi everybody, more coolant return.
Soft soldering in situ was successful.
The plotter has cut some gaskets.
The M 1,6 bolts will be replaced later against a hex type.
Another connection point is scheduled in the pipe to avoid a later split between the manifold and the two pipe flanges, because this will a nightmare to solve 8 times a M 1,6 mm hex bolt there.
Next part to make, that all is laying on the table for closing the loop, the long pipe from the head down to reservoir.
Kind Regards

Very nice work Achim, I’ve stated it before but the statement bears repeating; you’re building a beautiful model.

Soldering I something my eyes just won’t let me attempt any longer, can’t seem to see what I’m doing well enough without burning my eyebrows off :ROFL:.  The little soldering I need to do is usually substituted with Locktite.  :ThumbsUp:

Hi Craig, thank you very much.
Waiting for the next steps coming at your running project.
As mentioned before, I like the clutch you have made there.

Hi everybody,
here the place where the long coolant return pipe should find its new home.
After some fiddling around with all the little challenges here, everything is fixed now.
Kind Regards
Achim
