Hello,

I have lurked for a long time. Finally made my first engine - a wobbler from Steves Workshop - link to short video below - probably not the quality of work expected for this forum but I got impatient and decided to see if all of my accumulated mistakes and miscellaneous scrappy bits would work.

Quite amazing seeing it work - fairly chuffed - next project is Stewart Harts Pottymill.

Can you do anything useful with these little wobblers ? ie steam powered spirograph ? pencil sharpener ? would be keen to make something blingy for christmas presents.

Need to tidy it up a bit and make a decent base. Currently runs off 5 psi.

Nice work. Is the flywheel steel?

Ummm ............ yes its some sort of ferrous material - out of scrap bucket - wouldnt know any more about it than that - Oh ..... I think I get the point of the question - would aluminium be considered too light for a flywheel ?

Odd thing - cannot start the engine today ............ yet it worked so well yesterday ...... will pull it apart and clean it all and see what happens.

Bill,

Flywheels can be made of aliminium and work. Heavier materials are usually used and help when running slow.

Nice one.
 
For what it's worth,
An aluminium flywheel I made was a bit on the light side so I simply drilled 6 or so equally spaced holes in the side of the outer rim. Poured some molten lead into the holes to gain mass. Cleaned up the sides with a light skim cut to get a finished look asa though the lead was meant to be there. And yes, I did take precautions to minimise the likelihood of fumes during the melting process.

Hello I bet we can all remember our first ocilator! Was it not a magical experience? When it burst into life?
Best regards Tony Wright pufango!
