Saving Old Seagulls

I do not expect to be insulted, especially by a moderator. I'm out of here ...

BTW - there are NO 'boat yards' or 'chandlers' in South Lincolnshire ...

The competition for these items (blocks, tanks) is of course the second-hand market. That can happily supply blocks, but the tanks are a different matter. Couldn't disagree more. Tanks and blocks are opposite propositions: tanks are nearly always available (2 on Ebay as I speak - and there have bee...

140 The sample block might well cause some problems. Seagull cylinder blocks seem to have quite wide tolerances, if you take 6 identical (models) cylinders & measure them you will find many differences while the bores will will all be within 3 thou in diameter depending on wear, the port locati...

Is copper used as a base coat for chrome plate, followed by nickel, then chrome? I think it is. I don't want to sound too knowledgable about this, 'cause I'm not - but afaik, there are 2 types of chrome plating: the copper/ nickle/ chrome route is about plating for appearance - the chrome plate is ...

Which cylinder did you take you drawings from, for these enquiry's ? as it's probably the WS silver century cylinder that appears to be the most in demand. Are you planning on getting them to machine them or do you envisage paying English prices, give some thought to changing the cylinder threads t...

You're right of course - Ryton-on-Dunsmore - what I really meant to say was "NOT built in France" (despite the name).

When you talk to them ask if it's suitable for cast iron rings. Early Seagull sports had Nikasil lined cast aluminium cylinders but these ran "chrome" rings. Good thinking - Briggs and Stratton do something similar to their ally cylinder bores. Well - I've sent off 4 enquiries - 2 to Chin...

... most SD engines have legs in very poor condition due to rust and deep pitting, so the question opens up - "to try and replicate the original or not" Now I have a restorable leg, I must admit that chroming is looking attractive, but expensive! I will shop around and report back :D I've...

Thanks for that - saved me having to dig the reference data out ... Yes - these look ideal - certainly worth a try. On some of the fixed drives, there's already a rubber anti-grit washer in place, so these would simply be 'instead of'. On the S/C/Plus clutch models I have, this seal would fit betwee...

RS components (or "radiospares" as some of us oldies remember them) certainly used to a business-to-business outfit. But these days you do not need to be a business or set up an account (in the business sense) with them. I have ordered stuff from rs since before 2007 - you just register y...

Ehhrmm - a very good price (indeed !) - but these babies are edge seals for gearbox shafts, not petrol taps !

I'm told B.S. sell 8 to 10 new cylinders a year for £157 inc. Ouch Was it you who was a toolmaker? as this strikes me as a perfect job for a cast iron liner with accurately machined in ports with a cast aluminium water jacket Not guilty (wish I was) - very much a make-do-and-mend 'bush' engineer th...

On a tour of Ebay recently, I was struck by just how many powerheads were for sale - but always sans their Cylinder Block. From this I think it's fair to conclude that one less-than-optimal design feature of the Seagull is internal corrosion and marine concretion build-up within the water jacket, es...

Help wanted of a different kind ...

I'd like to order a pack of V12A nitrile V-ring seals from RS, but don't have an account - can anybody assist ? Ebay price: around a fiver each ... RS price 53p. And that doesn't happen often !

Well, maybe Manifold is on a rant - but he ain't wrong. As an aside: I drive a 25-year-old Peugeot 309, which still has 10 years left in it (not bad for a car built in Birmingham ... I keep wondering " what went wrong ?"), doing about 4,000 miles a year. My neighbour drives a 'low emission...
