I have a few damaged stanchions and wouldn't mind replacing them. The top life line runs through a plastic cap that has popped off on a few.It's an old boat with single piece stanchions (no seperate base plate) and I cannot find any on the market with the same hole pattern (55mm x 50mm). It would be good to use the same holes as some having backing SS plates inside the deck Would people normally get them fabricated? Sounds expensive. It's a cheap boat.
It should be doable but as you say costs can get out of hand. I have bought 316 stainless from Edcon and they are excellent - $10 minimum order when I purchased last.
It is not clear what you are after - just some more plate or flatbar to make the top pad which sits on the deck, and weld the stanchion tubes to them? If it is only a few (3 assumed) then you could buy the plate or flatbar of the right size and thickness, cut it up and drill it to suit the 55x50, and have a local welder weld the tubes to the plates.

See welders here, some mobile. Be less costly to take the work to their shop.

What is the yacht class, and what diameter tubes are they? Assume the plastic caps are not serviceable anymore? If so need smaller tubes welded into the top of the stanchions to feed the top lifeline through.
Boat Locker might have some used ones to suit in their vast holdings - call Mike

If they have some to suit which don't match the hole pattern it would be easy to make new backing plates.
Cut the upright of the existing baseplate and weld a new piece of tube to it. Best to weld a cap to the top and run the life line through the stanchion as I am not a great lover of the plastic caps. You should also weld a bit of tube into the holes that the lifelines run through. A stainless steel fabrication shop would do it in no time. I own a stainless steel fabrication business and the cost per stanchion would be about $10 for material and .75 hours of labour $75, a cost of about $85 each. The cost is in polishing so it is best to tell them that you are not looking for a show piece.
i have a related question - our aluminium toe rails are highly corroded around some of our stanchion bases due to electrolysis.
we're wondering what might be a good way to remedy this (short of replacing the entire toe rails, which is probably not feasible)...

Not much you can do. Best is to remove the stanchion clean everything up and refit stanchion with a good dose of Duralac. It will not fix it, but it will slow the problem. You could treat, bog and paint, but that is only a very temporary fix, but would look good for a while.

Cut the section of toe rail away at the stanchion bases , it will help the deck drain too.
