Six Shooter Elbow Engine

[Ken I]

Captain, Thanks for the kind remarks - but an even bigger thank you for your hand in this process.

I have posted it under finished projects and I have completed all the drawings and build log - but the downloads section is being cantankerous and I've handed it over to Bob to sort out.

Regards,
Ken

Here's a "prettier" video of it running.

I have posted the drawings as a *.zip file under the downloads section if you are interested.

It contains an Autocad 2D *.dwg & *.dxf file with each part drawn in a different layer / colour.

There is also a single sheet *.pdf of the same.

At this time the downloads section will not accomodate the large (5MB) *.doc file of build notes and photos.

(The download limit seems to be 2.5MB not 25MB as stated)

If you would like a copy of the *.doc file, send me a PM.

Regards,
Ken

A final postscript to the Six Shooter saga.

As regards the stiffener (between the two elbow axles) - I removed mine (as an experiment to see what would happen) from my elbow engine and it still turns over by hand and runs - pretty much the same as with it.
It sounds a little more "grumbly" when running so the reaction forces are probably springing the 90° slightly and my "springy elbow thingies" are taking care of it but at the expense of some increaced side load on the pistons.

I did this experiment to satisfy my curiousity in response to Captian Jerry's Swinging Elbows thread.

FYI

Hi Ken, is the porting on the base the same as 3 piston models. Regards, Bob

No - the porting is via the central shaft rather than the base - but is fundamentally the same tining - for half the revolution it is ported to inlet and for the other half to exhaust (with obvious gap to prevent blow by).
This was my fundamental change to eliminate the troublesome bleeding at the base unless the clearance is very closely held.
Also to eliminate the "throwing" of oil which has ruined a great many shirts during elbow engine displays.
You can download the plans off the download section in PDF or ACAD Dwg (currently at page 6)
A pity about all the missing photos due to Photobucket management having lost their mind.
Send me a PM and I can send you the MS-Word *.doc build notes if you are interested.

Regards, Ken

A pity about all the missing photos due to Photobucket management having lost their mind.

I hadn't seen this build before - fantastic job. I had a look back through the thread and all the Photobucket pictures appear to be displaying (I hear Photobucket have now reversed their disastrous decision) but the pictures stop where you announce you've changed to imageshack instead, which I think also went the fully paid route. Not that I'm recommending Photobucket after what they did, but at least some of the old threads that were destroyed are now visible again.

After five attempts to get one running the magic happened and the shop was well misted from the spray! So how to share the joy and keep friends clean ? I put a gear motor under it and pulley drive. It has been displayed in homes and no complaints of over-spray ! It is really interesting to watch.
