A Stirling and a Praxinoscope

[fcheslop]

Hello,
        I have for a very long time wanted to own a Plank Stirling engine with a Praxinoscope but have never been lucky enough to be able to buy one at auction.
The engine will be based upon the Plank design so if you should think that not enough of this build is to my own ideas then please move or delete it
First of I need to thank the people who have and are making this build possible as without there kindness it simply will not happen
Thanks Huib and sorry I kept you from youre bed
Peter Olausson for taking the time to give me some dimensions from youre original Plank engine
To Gottfried Malek and Manfred Graf for making youre work available through either forums or Machinen Im Modellbau 6/2009
So I now have some ideas rolling around my feeble head
Having looked at the Plank in the 1905 catalogue Im not keen on the engine just mounted on a block of wood but like the wrought frame detail of the other engine and this is the way forward I think.
The Praxinoscope and drive system will be detailed later would this have to be else where on the forum just not sure and would appreciate some one letting me know
So a start has been made and she is partly drawn up as I like to have a few bit n bobs to fondle as I go.She may end up a non runner or stuck under the bench in frustration like my rotating power cylinder engine.
Looks like a little bit of fabrication is needed and a good bit of spinning as I think that maybe the easiest way to make some of the burner parts.
Iv attached a few pics so you can see what Im mumbling on about.
The rough drawings will be posted a long with a quick run through the parts
Sorry gents and lady the drawings are metric as my graph paper is now metric :Lol:For some reason when building hot air I think in metric but for Steam imp just my whack y way.

well thats all for now time for a good malt and a bit of Mr Einaudi

By 'ek, Frazer! 

You do set yourself on, at times........   

Looking forward to watching this develop. Good luck, Marra!

How typically interesting of you Frazer. I'll be following, there's some elegant work there, and I'm wondering what pictures you'll use in the praxinoscope, a word that you don't get to pop into just any conversation!

Cheers, Hugh.

[fcheslop]

Thanks David, just divent hold ya breath she is going to be a long long slow build and I can see a large scrap sorry re cycling pile
Cheers Hugh , I keep having to check my spelling.
I have already looked into the Praxinoscope and  they are still made and sold you can even get one for $9
Automata is another secret hobby /collection I have from my dark and distant past

Frazer, always nice to see a new and in this case unique project starting up here. Looks to be a fun one to follow too!!

Sorry gents and lady the drawings are metric as my graph paper is now metric

 

There is going to be an interesting bit of fabrication in this engine

One day I might have to make another Stirling engine 

Jo

[fcheslop]

Thanks Bill, just keep me right
Jo thats a terrible confession  far better than those smelly petrol engine thingy ma bobs
cheers

[Jo]

I just need the right  model to tempt me.

[fcheslop]

Im sure there must be something that will
Just think no swearing when the prop bites or the HT goes were it shouldn't
cheers

Well here goes a little back to front I know but I wanted to make sure that she would work.
I will post pics of the drawings with each part as she now needs stripping and fettling and some proper screws fitting.
Would any one be interested in doing some proper drawings once she is finished for forum use?? as my pencil drawings are a little poor to say the least; That is if anyone else is daft enough to want to build one.
The ratio worked out at 2.31:1 so I was reasonably certain she would run and she didnt disappoint even with only 3 screws holding the hot cap on and a slight leak she will run of a candle.
I do intend showing the fabrication and spinning of the fire box/burner parts although Im totally self taught in the black art of spinning so if you know better then please chip in.
Well here she finally is in all her glory although she does need finishing
For some reason the video link is only showing as that small icon 






You can see the missing and mangled building screws.I tend to reuse these screws on every build then once finished fit new screws/bolts after first bluing them .
best wishes

That's an elegant looking engine    I hope you can get the video link to work. I have had many problems linking them so can't offer any real help.
Have you got the Praxinoscope (or even a Zoescope) sorted out?

[fcheslop]

Hi Rodger, click the little icon it seems to work
The Praxinoscope Im searching the baking isles for a suitable cake tin and Im looking for mirrors maybe ladies compacts knew I should have kept working for Rimmel
They are still available commercially but that would be far to easy
cheers

[b.lindsey]

Frazer, the video link worked fine and it's quite a fine little runner. Now looking forward to the praxinoscope part of the project

Well done!!

That is a awesome project Frazer, so is the Sterling engine. I want to see more on your Praxinoscope built, that is too cool.

Don

[fcheslop]

Thanks Bill and Don, Still a lot to do just on the engine.Then the counter shaft set up
cheers

[fcheslop]

Just a little update.
The nuts n bolts have all had a coat of oil blackening and the burner box has been constructed.
I had not realised how much work was in this little firebox.
The top and bottom plates ? not sure what to call them were made by spinning and then adding the extra detail by silver soldering rings into and onto the plates
Just the burner to spin up next then onto the counter shaft.
pic 1 the formers
pic 2 and 3 the toy as is.
Thanks for looking
best wishes

The burner housing and chimney are a work of art!

Someday I would like to give metal spinning a try; do you make your own tools? Would also like to know how you did the joint on the main section of the housing?

Dave

A very fine project Frazer.
I really enjoy seeing engines doing something...and this idea is really cool.

[Nicolas]

Awesome work, Frazer

Frazer, I can't get the third photo to load, my mobile connection, not your fault. I even drove down the valley to be near the tower, but no luck. I must have tried thirty times.  The spinning is better than an industrial job, but that's one of your fortes. The fire box...what can I say? I guess you just rolled up a tube (a tinsmiths joint?), then milled the slots as per the wooden bolster.

I must say, it worked well!


Cheers, Hugh. All the best for 2015.

Nicolas, you're a gentleman. Many thanks, an important view in my book. The Black Caps did well today! Good on them.

Cheers, Hugh.

[fcheslop]

Many thanks, sorry about the pic prob Hugh hope it was worth it
Managed to spin up the burner so just 3 screw holes to drill then onto the counter shaft assy
Dave Iv attached a pic of my very simple spinning kit. High tech
The joint over here as Hugh mentioned is known as a tinsmiths . A handy book is this one

Last post, Iv decided to put it to one side for a while thats once the base is finished
<a href="https://www.youtube.com/watch?v=SJRPA6bRZEQ" target="_blank">http://www.youtube.com/watch?v=SJRPA6bRZEQ</a>
Iv some boats to build and to finish and a Stirling car along the lines of the Lotus 7 wont be as quick but should be fun.
Time for a steam fix
Many thanks for the interest shown
kind regards

That's a sweet runner! 

Enjoy your diversion, Frazer.

A very smooth engine. Looking forward to boats and cars. Hugh.

[Dave Otto]

That's nice Frazer


Dave

[fcheslop]

Many thanks guys
Hugh the boats wont be on here as one will be a near scale build of Reciproca although Iv a few ideas for the engine that wont be to scale. Nor will the Stirling car.
cheers
