2 cylinder for a side wheeler

jimmybondi · Sep 8, 2009

Hi Carl,

its milled in 3D by CNC - thats what you want to know ?

finishing has been done in X and Y (cross way) to get a face like cast iron.
next i will brush it with a rotation brush - thats all

the pipe has got fine thread (M10 x 0,5) and additional stucked with "Loctite"

Yes. Thanks Frank. Nicely done.

Hi paddlers and steamers

today i assembled the first wheel
i have ordered only one pair because its very "unchap"
material: stainless steel 1,5mm
cutted: laser

(HiRes: http://irc.global-radio.ch/JimmyBondi/Diagonal/Paddle.jpg)

The screws are only "test-fit" because i'm awaiting some material like hex-steel in stainless

Frank,

That's wonderful, right down to the blade feathering mechanism. :bow: :bow: :bow:

Best Regards

Wow, I never knew they had variable pitch. Do you use a constant throttle position and vary the blade pitch, like a constant-speed propeller?

jimmybondi · Sep 9, 2009

Hi Vernon,

no - not variable pitch.
the eccentricity is fixed (a few mm to front)

The mechanism ensure that the paddles dive nearly vertical into the water and rise the same manner.
when using fixed paddles the diving one tries to lift the boat and the rising one pull the boat down,
and: the efficiency of such a paddlewheel is much lower than a "featured" one

ahh, yes, that makes more sense. ;D

This is turning out beautifully. I have been trying to find a set of plans for a sidewheeler can you give some info. on where you got these please?

Hi jimmiblondi
Sorry for my English..."loco builder" in my mind means:"Locomotive models builder"...
Best regards
Paolo

jimmybondi · Sep 12, 2009

Hi,

@John - the plan is from download-area here
the plan is one of Westbury from 1955 i think
(i've "redesigned it" to metric scale and changed some small details)

@Paolo:
not a model builder at all - i build everything that looks good, gives me time and area to add own ideas and sometimes gives me an advance - on my skill

last days i thought about the wheel, gave me a delay in turning the 96 screws for the wheel (but tody i've done it) and made some cosmetically works

at the end of a build everytime the same happens:

a lot of work and less to see :-(

ahh - i assembled and adjusted the slide valve - now the engine would like to work: when turning the crank shaft the cylinder begins to breath
(a quietly *ploooop* *zosch* on every stroke

)

Frank,

That is some really beautiful work! Loved the photos.

Awesome awesome. I can't wait to see it go.
Great stuff.

Frank, that is beautiful work!

Hi model engineers,

IT'S WORKING

i can show 2 videos:
the 1st is working at 0,6atm (and short 1.5atm)
and i have closed the tube from the feed pump to give a little "work" for the engine

the second video shows maximum 3atm

http://irc.global-radio.ch/JimmyBondi/Diagonal/Video1.avi
http://irc.global-radio.ch/JimmyBondi/Diagonal/Video2.avi

now i have to finish small things to complete it

Frank

zeeprogrammer · Sep 14, 2009

BEAUTIFUL! Just AWESOME.

You're going to make a boat for it aren't you? Aw..you gotta make a boat!
Okay okay. You're going to put it in a boat aren't you?
Gotta get a boat.

That is great stuff. The 2nd video would lead me to believe it's for a speedboat. :big:

Nice.

ariz · Sep 14, 2009

how I miss this project?
great built and wonderful running too :bow:
many compliments!!!

and what a fast built! your first post is dated 24 august (but many parts were ready at that time indeed

)

I don't understand where the water comes from... is it air condenced? so much? I don't think

oh yes - some parts were ready at 24th - i started first parts on 15th august

I don't understand where the water comes from... is it air condenced? so much? I don't think

no - no condensed

there is a feed plunger pump in the middle of the engine.
I take one tube into a bottle and want to knew what capabilities it have - also how much power is necessary

@zeeprogrammer:

maybe i build a boat - but it has to wait until late 2010:
i change location and to change with a home shop means a lot of work :-(

i hope that it work better on steam - and a little bit smoother ...
the 2nd video was only to see what happens on 3atm

(just thinking on a paddle steamer with nose into the sky ...

)

Excellant work! :bow: :bow: I found those on my computer in files I downloaded a few yrs ago. So many projects so little time.

ChooChooMike · Sep 14, 2009

That 2nd video sounds like a motorcycle rev-ing its engine !! Very cool :bow:

Debian · Sep 14, 2009

Hi Frank, many many compliment for this great engine, and thanks for showing :bow:
If it's possible I would like to know what kinda machines You used (cnc mill and lathe) and if You can say where is possible to buy the plans, maybe an old issue of a magazine? thanks so much.
I really hope to see a video of this engine running in the calm water of some lake, ok ok.... never mind, we can wait until late 2010!!!
All the best,

Paolo
