16 valve engine
« on: December 07, 2013, 02:16:03 PM »
Hi everybody,
here a quick summary of my current project.
I have bought a plan for a small steam engine which is valve controlled.
First idea was to make a compound from it and I have started my working drawings in CAD.
Than I decided to build a twin, and a two and more years project was born.
Here some pictures of the beginning of the hole mess.
Regards
Achim

Achim, that looks like a great start to a wonderful project! I shall be following along.

I like your machining steps in the CAD drawings. Are you using CNC?

Hi Simon,
I have started my CNC project  last summer time. So in the meantime I am playing around with this, but at that time the pictures are made, CNC was not a part of my workshop.

Hi everybody and Good morning,
here I would like to show some further progress of my 16 valve engine.
At the German ebay site there is a currently a model for sale, which looks like exactly build by the plan I have bought.
http://www.ebay.de/itm/380793945982?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
There is also a link to a youtube file showing the running engine.
Last year at Christmas my engine was nearly finished with the crank drive and cylinders so I could do the coating already and the final assembly of the cylinder assy with all sealing.
Regrads
Achim
Kind Regards

Very nice, Achim. Can you say what the blackening process is, and are those brass parts that you're blackening?

Hi Simon,
yes it is brass, which will be black burnished.
Surface must be clean, no oil or grease and no other oxides on the surface.
Best results with my fluid are with 80 to 90 C.
I can offer you the link to a German company only, but the Google translater will help you.

I am sure you will find similar stuff in the states.

second try to sent the post, the first one disappeared totally in the net, may be it is still in hands of the NSA........

Hi everybody, the next steps on my 16 valve engine. The cylinders are nearly complete now.
The ex-centers are made by SS. I lost 2 pieces and two 2mm taps from bad Chinese quality. After getting new ones from a good German tool supplier everything was fine again. I have made four 2mm threads in each part to adjust later at every possible position.
Then followed by all the tiny bits and pieces for the valve train.
Kind Regards Achim

(test with one picture only.....)
Kind Regards
Achim

Jo

Me too.

I might have some exiting news to share in the not too distant future.
I dont want to give the game away just yet, but it has been well worth the wait.

Hi Jo, the M34 piston drop valve mill engine plans are on my desk since 6 month. I have also all the old ME magazines from 1978 were the first documentation for this engine was printed. But after seen the MEM Corliss plans, I have done the decision to try this first.

Hi Bill thanks for your positive comments.

I have tried again now to download the remaining pictures but it does not work anymore.

Kind Regards Achim

Keep trying Achim. I know the admins are working on these issues and they should be resolved soon.

That's a stunning engine Achim and has a very nice appeal to it. I ilke.......... :ThumbsUp:

Simon the blackening can be done with Selenium Dioxide (selenium acid) for brass and copper.
