Hi Craig, very nice work.
And yes, I think this are really small parts.
I can follow you explanation about the movement of the single parts and the function.
Waiting for the rest of the story, the linkage to the fuel valve and the valve itself.
Thatīs a small masterpiece indeed and very well done.
Kind Regards
Achim

Anything that involves 2-56 screws and threads feels intimidatingly tiny to me! It's looking good, Craig!

John, Art, Achem, Andy; thanks for the encouragement and comments.  Thanks also for those of you taking the time to just silently stop by to see the latest.

Itís been a few days since my last post; but Iíve been busy.  I was a bit negligent in ordering the flywheel castings (in fact I just got to it today).  I could use them now, but there still is a lot to do so I can afford to wait a while yet.  Iíll be using the same 10 Ĺ inch flywheel casings I used on the Crossley Otto Langen, and probably be removing around the same amount of material.  This engine is characterized by large diameter flywheels with thin rims that, in my opinion, gives it a lot of its ďcurb appealĒ.

Iím currently working on the fuel pump.  Below is a photo of the pump on the full size original so you can see where Iím attempting to go.



Here are a few photos of my progress so far.  The fuel pump is ďfront and centerĒ on the model so it deserves a bit of attention to make it look somewhat like the full size castings.

Thanks for stopping by to see the going-on.

I spent the entire day working on this pivot arm.  It took two tries; the second attempt came out not great, but acceptable.  The remaining parts to this fuel pump should be somewhat easier to make.

Maybe a watchmaker could put in all those fillets and chamfers.

Craig,
That looks like quite a lot of work for such a small piece. It looks great! You look to be making good progress.

Craig, I think you made a mistake. The part is much smaller than the drawing on the plan ... :)

Continued excellent work on those "fiddly little bits"!

Roger, Kirk, Art, Andy; thank you for your kind comments.  Thanks also for those of you silently stopping by to see the goings-on.

I was thinking of asking George to make the above pivot arm for me :ThumbsUp:.  The only problem with that is, George would have made it twice as small  :facepalm2: and when I put it on the engine everyone would have commented, Ēthe pivot arm looks great, the rest of the engineÖ not so muchĒ.  :embarassed: :ROFL:

Iíve finished the fuel pump.  Below is a photo.  I would have placed it on the engine for a final shot but, I had a few misaligned holes on the base to repair with JB weld and couldnít re-assemble everything while the cement dries.



I probably wonít post for a few days.  Tomorrow Iím having the cataract in my left eye removed and Iíll be doing my best impersonation of Edward Teach (Blackbeard the pirate) :lolb: for a day or so.  There will be restrictions on my activities for the next few days but Iím hoping to be back in the shop early next week, and Iím hoping to be able to SEE!!! :pinkelephant:

Iíve received the material for the cylinder liner today so that will probably be first on the agenda.

From what I have heard from the girls cataract operations can be life changing, just make sure you remember to use the drops they give you ;) Best wishes for a rapid recovery.

I have an appointment Monday with eye doctor.  Almost certain to have cataract surgery soon.  One of my eyes is still good, so together they work fine, but with good eye closed I can tell how bad the other is.  Good luck with yours.

Best wishes with the surgery, Craig.

We will miss your posts while you are away, but it is important to look after your eyes first.

I am sure we will all be looking forward to your return.  I know that I am one of those looking in every day.

Back from the hospital and I'm told all went well.  When they take the eye patch off tomorrow we will see.

The operation was nothing.  The worst part was the reqiured Corona virus test they gave me where they rammed this cotton swab about four feet up my nose.  Hurt like... well, can't use appropriate words here where we wouldn't all blush.
