Where might I obtain the square headed bolts and nuts for this project,the source in the articles does not appear to stock them any longer.I note that the Guild of Model Wheelwrights are also looking for them.

Square nuts here and here And I think its a case of silver soldering nuts to studding if you want bolts though making your own is likely to be easier.

I bought the back issues a while ago with a mind to making it 50% bigger, should not be too hard as they are all described as fabricated.

There are a few pics of a nice one here, just a bit too much shinny brass for my likeing though.

Hi JasonB

I have seen an all fabricated dredger engine and it ran nicely on compressed air.

It was built at drawing size though.

Diane is doing a Special magazine and it will include the drawings of the Trevithick Engine as a pull-out.

More information in the next few weeks.

Brian if you look at the dates of the early posts they are quite early on in the sites history. Since then a lot of the old stuff that was scanned and made available has been removed en-mass due to a few copyright issues. Not helped by newbie Keith resurecting an old thread rather than starting a new one

David, are you going to publish just the drawings or text as well? if just drawings is there any chance of uploading the test again?
