Hemp wadding plus grease? Vintage steam railway or tractor enthusiasts may be able to help? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=20570#post-350784 Tue, 18 May 2021 11:26:22 +0000 neddie 350784@http://citycyclingedinburgh.info/bbpress/ <p>So, Laings foundry are (hopefully) now producing a rodding eye cover for me.</p> <p>Just two more things I now need:</p> <p>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.</p> <p>2. Some kind of traditional gasket or sealing material, not sure what this would have been? - possibly hemp mixed in with something.</p> <p>Anyone got any ideas where I can source the bolts and find out what sealing material I should be using? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=20570#post-350167 Fri, 30 Apr 2021 14:57:10 +0000 chdot 350167@http://citycyclingedinburgh.info/bbpress/ <p>Contact <a href="http://www.laingsfoundry.co.uk" rel="nofollow">http://www.laingsfoundry.co.uk</a> (formerly of Broughton). </p> <p>Might even have a (wooden) pattern of what you need. </p> <p>No idea on cost. </p> <p>“</p> <p><a href="http://www.laingsfoundry.co.uk/products-services/">Craftsmanship at a price comparable to mass production rates</a></p> <p>“</p> <p>They made all cast iron signs along the WoL (and a LOT more). </p> <p><a href="https://www.pressreader.com/uk/the-herald-1130/20170613/281891593257743" rel="nofollow">https://www.pressreader.com/uk/the-herald-1130/20170613/281891593257743</a></p> <p><a href="https://m.facebook.com/edinburghworldheritage/videos/1377656142262760" rel="nofollow">https://m.facebook.com/edinburghworldheritage/videos/1377656142262760</a> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=20570#post-350164 Fri, 30 Apr 2021 14:03:10 +0000 neddie 350164@http://citycyclingedinburgh.info/bbpress/ <p>Does anyone know of anyone that can do cast iron (sand) castings?</p> <p>I'm looking to replicate a cast iron rhone-pipe rodding cover, as a one off.
