2 cylinder for a side wheeler

[jimmybondi]

Hi,

i just started a new project:

a two cylinder diagonal for a sidewheeler - free build with the plans of E.T. Westbury

some pictures say more than a long letter with lot of words.

but before i post the pics a question:

i need small valves to keep the water out of the cylinder when they are cold
(don't knew the english name)

they should be opened from a central point - like the valves in a locomotive.
any hints ?

ok - here the pics and some facts:
mostly used gun metal like cylinder, rods, steam chest,crosshead, eccentric strap, exp. link, ...
bearings are made of bronce ...


Regards
Frank

PS: i'm building 4 engines - not an 8 cyl

cylinder and rods details:

cylinders, eccentrics and connecting rod:

parts for one cylinder:

the eccentric is build of gm (strap and head) and the connection is made of steel plate
more parts:

parts of the eccentric:

For a "just start" I'd say you are well under way!

Looking great! Thm:

Or, since its a boat; it could be under weigh

Nice looking parts. Should be a nice build to watch.

Frank,

Cylinder drain cocks/valves. Usually cocks with 90deg from open to closed. You can fit one at each end or join both ends with a piece of pipe to one cock mounted on the stem of a "T" in the pipe. Rod linkage from each cylinder to your central point.

The other option is to use steam traps which operate automatically but size could be a problem, i.e. to get them small enough. Hopefully some others may know more than I, which would not be difficult. :-\

Best Regards
Bob

Hi,

@Bob:

i will see how to made the cocks.
maybe simple stainless steel ball and a spring, opened by a small shaft ...

not sure but i have enough time to think about - the prgress of the engines is not very fast ...

actual state:

- crankshafts ready
- a lot of small screws done
(hex screw 3 / 4 mm, metric thread M2 and M2,5)
- main frames drilled and milled

Nice! ;D


I've seen draincocks that were a second "spool" or sliding valve under the cylinders, but with the grooves spaced so both ports opened at once.

Found a little piece that gives dimensions for the drain as being 1/25 to 1/50 of the piston diameter varying as the pressure is higher or lower in that cylinder.

I apologize if you already know all of this, :-[ Maybe it can help someone else as well.

Ja! Ganz schoen.

Umlaut! I need an umlaut. Ah...I'll steal it from Arnold.

Ja! Schön! Ganz schön!

Scale! I need scale! Stick a coin or ruler on some pics please.

That is really nice work. Are you going to put it in a boat?

Alt 148 = ö

where the number is typed on the ten key keypad while holding the Alternate key down. Alles klar?

Beautiful!! :bow:

Great job!!!! :bow: :bow: :bow:
Are you a loco builder?
Best regards

[jimmybondi]

Hi Paolo,

what's a "loco builder" ?

i build everything that interest me and don't exceed my capabilities

here are two pictures of one complete machine in actual build state:

the 3 batteries are AA-size and alined in the 3-coordinate-system to get a aspekt-free imagination of the dimensions

better resolution to view here:

now i made a feww days work-free - have to get free head and enjoy last summer-days of '09

EDIT: corrected batterie size

Hi steamers

now i finished the engine as it

there are some small options to to (feed pump, wheel, some links, ...) but the engine is completed as working one

i've build small drain cocks (on first picture left - what a terrible work for my grossly fingers ) and now i'm not sure where to fit the links ... i'll find a nice place during building

the aluminium wheel will be replaced by a pump eccenter when i build it.
But to test the engine i need a connection between both crankshafts ...

here the pics:

or - better resolution (but to big for a forum post)

I like the looks of that one. Especially the choice of studs and bolts you made. They look like they belong on that engine. Beautiful job, what with so much detail involved.

Jealous of everyone elses talent,
Kermit

yesterday and today i finished the plunger feed pumps.

half day i has to invest to repair my mill: the shaft of the stepper (1/2" diameter) was brocken :-(

but today all went right - a little less speed as the new motor is a little bit less powered ...

here a the pumps:

Greets Frank

BTW: yesterday i got the parts for the wheels (only one pair because of the price) - laser cutted stainless steel
I will weld them (TIG) next days and show it

 

[zeeprogrammer]

Nice work!
I don't know what the various parts are...but how did you make the 'bottom' part? That is, the part that has the bottom flat?

(Psst. Scale.)
