 :Lol: I kind of figured Chris would chime in here. He's been looking at chain for his project.

Geoff is in the UK and I don't doubt chain will be found.

Yup, Dan pointed me at some nice heavy oval link chain, and I have found good bike style chain too.

As I recall, Mc Master has some stainless chain down to .187" pitch but it's pricey as gold and may not help in the UK.

Geoff do you know what pitch size you need for the chain? Simply Bearing stock simplex roller chains down to 6mm pitch off the shelf: https://simplybearings.co.uk/shop/Engineering-Parts-Chains,-Links,-Sprockets-&-Platewheels-Roller-Chains-Simplex-Roller-Chains-BS-European-Standard-Simplex-Chains/c4713_5487_5488_5489_6103/index.html

Renold's do 4mm pitch as a standard size (Bogstandard had some kicking around in his spares as I have just found a couple that size he let me have ;) ) I recall Cherry makes her own chains for her models  ::)

If you want to go really tiny then think about Pocket watch fusee verge chains  ;)

Hi Jo
Thanks for you interest in finding a small chain, I had another look at some pictures of original engines and scaled the chain pitch to around 1/4" so it will not be to difficult to find. When you first start searching you have to find the right description to take you in the right direction. I have found some on ebay and will get that as a trial to see how it looks.  My model will be a combination of ideas from the original and the plans from Julius modified by what I think I can do.

The very fine ditch digging machines shown at NAMES this year was scaled to the smallest size roller chain the builder could find.  I can't imagine making chain that small.

Here's an update on the chain, The smallest practical size that easily available is 6mm pitch and cost approx. 6.00 a meter and I have now made my first attempt at making a sprocket, which is interesting in itself, I just wanted to see how this would join up with the wheel and what space is needed.
I was also pleased to make up a small belt sander from a handheld powerfile I got for 25.00 on ebay. I have wanted a belt sander for a while but have not got much spare bench space. I might do a separate thread on my homemade sanders.

Thanks for your interest in the chain, anything smaller is very costly so I will see how it looks for now. I've made some new mounts for the leaf springs as I felt these were the parts most out of step with the original, also I would say to anyone contemplating building this to think about making the bolts smaller than the plans say as again they can seem oversize.
