Does anyone know of anyone that can do cast iron (sand) castings?
I'm looking to replicate a cast iron rhone-pipe rodding cover, as a one off. Cost has to be reasonable.
Thanks.

Contact http://www.laingsfoundry.co.uk (formerly of Broughton).
Might even have a (wooden) pattern of what you need.
No idea on cost.

Craftsmanship at a price comparable to mass production rates

They made all cast iron signs along the WoL (and a LOT more).

So, Laings foundry are (hopefully) now producing a rodding eye cover for me.
Just two more things I now need:
1. Brass square-headed bolts are meant to be used on these covers, presumably so they don't seize, or damage the cast iron. No idea what size, but no doubt imperial, around about 8mm x 25mm.
2. Some kind of traditional gasket or sealing material, not sure what this would have been? - possibly hemp mixed in with something.
Anyone got any ideas where I can source the bolts and find out what sealing material I should be using?

fleaBay may yield the bolts, it has most things.
As for the sealing, not sure. Hemp wadding plus grease? Vintage steam railway or tractor enthusiasts may be able to help?

It wouldn't be grease, as that absorbs water over time

Gasket rubber or cork sheets can be bought and then cut (by laser or hand) to the correct size.
No idea if this is "traditional" or not but it's probably more traditional than plumbers' putty or silicone caulk!
If your foundry has general metal-working facilities they should be able to turn and thread bolts from brass hex stock.
