1st post - 1st machine - whats next ?

[jimmybondi]

Hi,

i'm new to this forum and want to introduce myself:
i'm 42 years young (will become old without to do anything :-) ... )
my hobby is CNC-machinery - self made and i live in germany.
As i'm not able to work in a factory anymore i've to do anything - here's the first result:

a few weeks ago i start to build a steam engine - without castings - only a plan for a 2cyl machine without reverse gear.
but i'd like to do a little bit more - but see yourself:

irc.global-radio.ch/img/Fertig04.jpg
irc.global-radio.ch/img/Fertig05.jpg

material of cylinders, pistons, crossheads, rods, flywheel, chest and crank are cast iron, rest is steel and brass

dimension: ca. 8" long, 3/4" stroke, 5/8" dia
a lot of 400h work
the cylinders are milled in several hours to get them look like castings - the rods too. another detail inside: 2 piston rings per piston made of hard brass, working in bushes of bronce
air consumption: a lot :-(

the machine is working from 1.2atm on and produces at 8atm roundabout 350 watt, but has to be braked - otherwise the revs will count very fast - too fast :-(
it didn't work below 280rpm :-(
at 2atm it will reach 2,500rpm (all at compressed air - no steam)
what to do: governour, pump, gear - anytime (maybe)

now i'm looking for a balancier (like "Mary" or "Beam") and/or a 2cyl horizontal like "Twin Victoria" - or - i can't believe to get it in my live - the machine of the SS Gallia (a swiss ship)

has anyone such plans which have the base to became a "old-style" looking machine ?
a "Stephenson" or any other machine with a "unusual face" is welcome too - just to put a 2nd machine beside so that this one isn't lonesome at night :-)
the next machine should be a little bigger to get low rotation at the crank
- my opinion: a livesteam has to work slow - very slow and look very old and used
also i'm not a fan of in light from the brass flashing engines

if anyone is interested in more details: let me know

regards Frank
(sorry for my english - i try to give my very best)

Welcome to the forum! Nice looking engine Frank - you built this in a few weeks? Amazing!

(Rest assured that your English is much more understandable than my German!)

Hi Frank,
A good looking engine, and if it runs at 2500 rpm without shaking to bits, it must be pretty good!
Welcome to the board.

HI Frank,
excellent work on the engine...this site might be of use in your search for some thing else to build,,,

All the best for now,

Keep a look out for Yorkshireman Frank, - Johannes, a fellow countryman who also posts on here. Your English is far better that most of us can speak German.
Regards Ian.

That's a nice engine Frank, a real work of art. Welcome!

[jamespetts]

Very lovely engine! Should love to see a video of it running.

Sehr feine Handarbeit Frank, einige hier können doch Deutsch, aber es ist ja unhöflich, wo sonst niemand die Sprache versteht. Bei Euch gibt es wohl hervorragende Modellbahnen.
Halt uns auf dem Laufenden für deine weitere Projekte.
Tschüß

[jimmybondi]

Thanks for the compliments :-)
not at least the very good german spoken :-)

a running video with 2atm could be viewed at:
irc.global-radio.ch/img/DM.AVI

btw: i'm looking for a plan like the engine of the Gallia, a swiss paddle ship.
if anyone knew something please let me know.

Another machine i'll build is a valve driven, compound, with 2 pistons on a rod and 2 parallel - 4 cylinders too - the plans are just in progress (only modify and extend)
basic is this one: irc.global-radio.ch/doc/Test.pdf
atm i'm thinking about steering without bevel gear

Very nice! Impressive at high RPMs. What pressure was that running?

Hi jamespetts,

it was at 2atm and roundabout 2,500rpm

but i didn't like high rpms :-(
i would like to drive it at 100 oder 150 rpm but it didn't work below 280 ...
