I am now the proud owner of a 3 1/2 inch Maccsteam boiler for my first steam launch build. I am assembling all the necessary bits and pieces but have come to a stop in my search for a brass chimney cap for the 28mm chimney. I have no workshop facilities so I need to buy one. Does anyone know where I can obtain something suitable?

Although the web site doesn't give any dimension you could try http://www.mamodparts.com/spares-Chimney.asp?part_id=100562. They do spares for Mamod engines!

Why not use a 28mm olive from a compression fitting ? They can be bought separate from the fitting, at a plumbing store.

Thanks for the link. I have contacted MamodParts and their response was 'These are meant for a 3/4 inch (~19mm) ID chimney and would therefore be way too small.', so that's out. Nice looking capping though.

I would never have thought of a brass olive. It might be possible to modify one to provide a suitable capping.

Thanks both for your responses. Looks though like I may have to find a friend with a lathe to turn me one up.

Give Mike at Maccsteam a call.  Although not advertised on his website, he sometimes does a short run of brass caps for his chimneys - I have one and it fits like a glove - and really looks the part as well 

Good luck

Well done!! Mike at Maccsteam had one left and it is on the way.

Mayhem strikes again.

Excellent!  You won't be disappointed.  Glad to have helped.
