Hi All,

I am a 'newbie' to the world of model engineering. In fact I still haven't got a lathe yet but I'll hopefully correct this at the upcoming Sandown engineering exhibition in December. I am very excited & inspired by all the models etc. that I have seen & will likely go for one of the 'simpler' wobbler engines as a first project. 
 

Anyway - I have been reading up loads & trying to get to grip with some of the techniques etc. I would at sometime love to have a go at Mike Freeman's metal chess project that featured in ME earlier this year. Key to making some of the parts is the ability to machine balls - I see that Mike made his own custom tool for this job. So my question is does anyone know of an inexpensive ball making jig for small balls (Less 10mm radius) or perhaps has links to good (easy) DIY projects for such a device.
 

Many thanks in advance,  John

Thks Ian I will give it a try. Out of interest do you have any links to the engines you have made - Cheers,  John

Hi David,
 
Looks excellent for a first project. I have only just joined forum (in fact this is my first post). I haven't got a lathe yet but hope to get one soon (perhaps at upcoming sandown Exhibition) - This looks like an excellent first project for a newbie like me that has no prior machining skills. The webpage/ description etc. looks very informative & it's all in Metric
 
I see that you have made a few minor changes which improve the looks. Out of interest could you just make the cylinder out of a single piece of brass rather than two pieces - the cylinder top with the 3 nuts on looks a bit complicated & I am guessing unless you get it right will leak air like mad....?
 
Anyway, if I can post a first project  that looks half as good as your engine I will be impressed..
 
Cheers,  John
