Jordan, if you have a local foundary where you will get your patterns cast then go and speak to someone there, show them your drawings etc. and ask advice. In most cases you will find them very helpful. If your foundry isn't close by, then speak to members in your local M.E. Soc, someone there will have done it before. Good luck.

Hi Jordan, Have you looked on the Society's website pattern bank to see if there are patterns available there that you could use.

Hi Jordan.

There are a couple of books in the "workshop Practice Series", "Foundrywork for the Amateur" and "The Backyard Foundry".
These will give an insight into the whole process.

As you saw at last year's AGM the castings I had done for Dougal in 7.25" have come out pretty well from my own patterns. Depending how complex or detailed the items are decides the standard of the pattern. If you just want a lump of metal roughly the right shape to machine up then it is a lot simpler than, say the pattern I made for Dougal's wheels which have holes cast in and a raised face for the crankpin and wheel centre where there is a lot more that needs to be left as cast for the final shape.

That reminds me I haven't really touched Dougal in several months, I must get on with the chimney and cyl patterns.

Cheers

Chris

Probably one or the other title would be sufficient rather than both. You could look at lazer cutting for W irons.
