Hi guys

Here is a short test of my little Robinson ...

I like very much Robinsons ... I think they are very elegant machines !

A HUGE THANK YOU to Odilon, who helped to get this one !


I posted it in the video section, because I had a success run ...  

Well, that happened after few unsuccessful tests, and I was not able to run it again !

If you can share advice,  tips ... to help that would be great !  




I tried these  ...

oiling, not oiling ...
( as the whole thing seemed to be VERY tight ... )

a larger burner ... actually, this runs is with my Heinrici's burner...

top of flames closer to bottom of chamber... I raised the burner of , say , 1 cm ...


I filled the tank ??? with cold water ...

I am unsure this was intended for  ...
Some Robinson features shilling tank, to use with a pump ... but for this one I am not sure...
The small screw of side doesn't seem to blank the tank ...      

At last, I loosened the axle with all rods ... as I thought it was some tight too ...

Then, after 185 pinches on the wheel, it started to run !
( and smoothly ! )
I just had time to grab my camera ... as a proof !

( and this is why I stopped , because I was about to spread rod and nut everywhere ... )


I screwed the flying nut back, but I had no further success to run it again ...

Any idea will be welcome, than you !
As for maker, unknown to me ...

Than you for your help , David  Thumbs up!

I already had a look to your topic(s) months ago ... but that is hi level technical machining langage ... and I need a dictionary every 5 words ...  
Now I have a Robinson I will have firther look    ...

Surprise is that it can run with a simple esbit tablet !
Certainly need further investigation ...


For now, I still do not understand what is the purpose of the side blank cap ...

It is linked to displacer chamber ? ...

Sorry David, I missed your question !




This is about this very cap ...
I thought I could drain water from tank through this hole...
I was obviously mistaken ...

Oliver.
That is the blanked off, end of the tube, which links the displacer chamber to the power cylinder....

Some engines have a screwed in plug. To allow leakage, for speed controll.

I don't have a clear pic, of mine. The knurled screw, seals against the end of the pipe.......




The water fill/ drain, is the hole to the side of the power cylinder.
