Kind of you Peter - probably 1/2" but I'll have a measure.

I've got two longer cheeseheads that you can cut down.

Drop me an address and I'll do it Tuesday.

As I said, kind of you Peter and if the Iron Horse air filter works out I'll slip you the necessary and you can pop them in with that. Otherwise, seems a bit daft paying Royal Mail to transport a couple of wee screws!

Got home for lunch to find Prepair jiffy bag on the mat. Thanks Peter.

Well, that was over three years ago and I have just got round to making the bearing shells!

Sure enough, I roughly sawed a couple of oilite bushes in half and finished on shaper. The bushes I had to hand were a bit short but I shall make a virtue out of a necessity and pop a little felt washer each side to hold oil and keep the muck out.

After that unaccustomed burst of activity I couldn't resist a play with another couple of little hot air engines.

First is a Moriya fan which was a very early ebay purchase of mine which, after re-making the crankshaft and fitting a new power cylinder salvaged from the mortal remains of an engine the Milestones gave me, it runs very well.

The second is a beautifully made Japanese job with buit in generator which goes like a bat out of hell and actually produces enough power to run a pocket radio.
