Anyone know of any very good marine shaft / stern gear engineers around Bristol or within 30 miles of?

If you don't get any local recommendations, try Lake Engineering in Hamworthy,
Poole. Very professional and helpful.

Not 30 miles I am afraid, but I have dealt with these people and found them to be very good.

What are you doing that requires a specialist engineer to work on a prop shaft?
I only ask because I avoid going into any place that the word 'Marine' in it because that generally means an extra 30% on the final account.
Good luck and fair winds.

Very true. Lake quoted me £270 for a new shaft but a small firm in Bangor made me one for £80.

I was under the impression that shafts are made from more than just normal high quality 316? I thought there were certain additives that gave it additional strength and additional corrosion resistance?
My point being that a normal stainless engineer might not have that experience / stock.

Not that I am aware of. 99% of stainless steel propshafts are made from AISI 316. Some 'problem' ones may be made from Duplex 2205 which is stronger and has better corrosion and SCC resistance but its cost rules it out for most, Jeanneau use a 400 series material that is markedly inferior but cheaper.

Vyv,
Out of interest, this was the spec for the original C&N prop shaft supplied to my 1980 Nic39. Subsequently replaced with 316.

Have to agree. Great little company and worth going to see them just to see a real engineering company. I have a
Ways had excellent service from them at good prices.

I heard they were good but can't get an answer on the phone. Also they bout 1.5 hours away so wanted to avoid 6 hours of rounded trip to take and collect.

Not a recommendation as I do not know the company but a google search came up with this in Bristol ...

I deliberately wrote 'stainless steel propshafts' to avoid the likelihood that people would raise the topic of their bronze ones
Very nice material, no doubt quite expensive.

Duplex, as I wrote in post #8. Not often used for yachts, except possibly for big expensive ones, much more common on mobos. Its big advantage is that it can be strengthened by heat treatment, unlike 316.

No. For all practical purposes 316 is fine and the only vaguely special requirement is in terms of straightness for use as a shaft. Only an engineer in a pretty big way would keep their own stock - thats what the stainless and alloy stockholder is for, to supply a few bars at a time.

I seem to be the only person to actually address the question and have attempted to help giving the OP a link to a Bristol company.
What response have I had from the OP --NONE, despite him having been posting today on another thread.
This seems to be happening more and more when people ask for help then ignore that help and or the people that provide it..
I really don't know why we bother.

I wouldn't get too worked up about it.

You bother because it helps and it helps someone like me a lot who has never refit a boat out before. The fact is that I called your contact first in Bristol but they don't have marine shafts in stock and without marine experience wanted my prop and the shaft etc. That wasn't too much of a problem but didn't have the confidence if they hadn't done many marine shafts. Maybe I should have had the confidence in them and they could have made a perfectly good one at half the cost but the boat has to go back in soon and C&O said they can turn it round in less than a week.
Trust me, there is no one more appreciative of the help I get on this forum I'm yet to start a thread that hasn't been invaluable.
