De Dion engine - update

[John Stevenson]

Got the muff casting from the foundry this week so I thought I'd better do a bit.
Set the crankcases up on the CNC mill by sandwiching them between two angle plates. Had to use the CNC in manual mode as they were just a tad to high to fit on the Bridgy.
Faced the top to clean up as I had to plug the existing barrel stud holes and also weld a 3/8" thick piece of alloy onto the cases to take the side studs. I then bored the mouth out to take the Liberty barrel.




Next two shots show the machined muff fitted to the crankcase and the last shot shows the whole lot assembled.

Nar,
It's going into a 1909 Peugeot car,
might need you to help crank it over though.
It's going to finish up as a 2 litre one lunger.
Next job is the crank, just had two disks profiled at 13" diameter by 1 3/4" thick,
That should make the Myford grunt

Wow! I thought I was looking at the engine I did about 10yrs ago. It was for a 1901 Buick (Replica). The mounting ears are different though. It sat horizontal with the cylinder to the rear. (Similar to 1903 Ford)

Nice going John!

What purpose does that piece serve? (Muff? - That means something entirely different to me.)

[John Stevenson]

Ken,
The muff casting is to convert the top of the crankcases which are 4 stud to take the liberty barrel which is 10 stud.
Also the crancase can be bored out to take the larger barrel register but not all the way down hence the conversion piece.
The register on the bottom of the barrel goes thru the muff and into the crankcase but only by 1/2", just enough to register.

BTW, muff also has a double meaning here as well. The true meaning is a fur lined hand warmer, open at both ends. Unofficially it's also been adopted as meaning any metal connecting piece resembling this.
Some adaptor pieces here to join two shafts together with either clamps or keyed holes are often refered to as muff couplings.
The slang meaning here is the same one as you know
Makes for an interesting conversation in mixed company

A two liter one lunger... man, I'd love to hear that puppy run! Looks as if things are coming along nicely.

You have some neat toys John.

John,

I do hope when you are finished with this project that you will take the time to take a picture or two of the final result. I gather from your previous comments that the gentleman you are making this for intends to race the beast?

muff > muffler > hauberk > A tunic of chain mail worn as defensive armor in the 12th to 14th centuries.

John
Does adding the muff between cylinder and crankcase increase the length of the stroke, and if so how will it be coped with.??? Is there room in the crankcase for a longer stroke crank?? Or is this cylinder shorter than the original but of larger bore diameter???
Also is that the floor of your shop?? if so I like it, looks like mine.
