they are easy to make I have to on my trike for steering. just welded two bolts on the end of some tubing.and screwed in those Olive joints, rubbish with technical names. Rose joint ? en.m.wikipedia.org/wiki/Rod_end_bearing

Its competent but I would have used a bottle screw arrangement as the tensioner rather than a slotted bar. Personally. A bit more complex but its a very effective way to position an alternator. Keeps the tension exactly as you want it and is easy to loosen for belt changes. As they say :"Many roads lead to Rome".
You would have used a different road, which is fair enough, but to say that what Kris made is rubbish, is rubbish.

It was a joke I think kris knew that.

It was a joke I think kris knew that. I thought that it was supposed to have been a joke, but started to wonder about it, as usually your jokes show one of the yellow signs (emoticons ).
But as you say, Kris surely knows that you can't be taken too seriously .

You can't be taken too seriously Quite right. It's taking things too seriously that causes problems. Going back to the alternator mounts for a moment - anyone with half a brain can see kris has done a good job there so I thought I'd have a giggle. I couldn't do it that well (in my head I can design it and visualise it but translating that into action is the problem. This is one reason I steer clear of old boats). I do think threaded rods are worth serious consideration for the pensioners.

Jag XJS alternator tensioner For ideas I just think a threaded rod is likely to be more satisfactory than a slotted bar. I find all boat stuff naff!! cars have had reliable auto tensioners for years, they improve the life of the belts, eliminate belt squeal and stop waterpumps and other stuff being damaged by over tensioned belts!! You would think in this day and age they would adopt this tech but no that would put boat fitters out of business shitehawks that they are [some of them not all]

I put a new Beta 90 (Kubota 3.8) in my barge in 2011 and I opted for the second alternator (175a12v) they fitted a threaded rod tensioner to that one and a poly-v belt but the original smaller alternator has the old type slotted bar tensioner and a standard v belt.
I think one of the reasons vehicle type systems have not found their way onto boats is that there are fewer auxiliary items to drive. Canal boats don't have a PAS pump and AC compressor (would be nice though !) and also vehicle engines are packaged to fit into quite a small space so the use of a serpentine belt is appropriate. On a boat it is better to have an extra pulley rather than wrapping a longer belt around everything. Usually there is more space.

Not a great picture but it is possible to get an idea about how they designed it. Looks like a combination of slotted bar AND threaded rod. Quite interesting I had not really looked at it before other than noticing that tensioning was by a threaded rod (in this case a fully threaded bolt). Many paths to Rome as Peter put it

On my very ancient Citroën Xsara Estate 1.9D, that was possibly left behind by Napoleon, they've made a very clever system to regulate the tension of the alternator (or really the auxillary belt) ajustable with a treaded rod system that's ajusting a tensioner roller and a fixed mounted alternator. This system does work really very well, too bad the picture isn't very clear, the adjustment system is on the right of the picture Peter.
