Gibb Self Tailing Winch

[Wing Mark]

I've got one of these with the stripper arm missing. I mean the red pointy thing, left side of picture.

Am I correct in assuming it just fits in the vertical shiny tube, and rotates to pull the rope out of the v-groove?

I assume I have no chance of buying the spare part?
What should it be made of?
How should it be held in place?
Are these winches any good? or should I just look for a cheap Lewmar?
What size rope are these supposed to work well with?

Do I assume that I load the turns on the winch, then turn the stripper arm into the v-groove?
How old would this be? Pre 1986?
TIA.

It's basically just for main halyard and reefing lines.

I found a smaller picture...

You might get one from Cliff Mogridge, Winch Servicing, Emsworth, if he is still trading. I got parts for an old Gibb winch from him a few years ago.

shows the rope routing and dates it to 1981. I did have a pair of these for a short time in the 80's on a Vivacity 20. They worked OK from what I recall.
The stripper arm was some sort of plastic and I think was just a push fit into the tube, it did swivel but it was not necessary to swivel it during operation.
They were not on the market for very long.

Thanks, picture gives useful info on the shape of the arm.
I'm wondering whether I can 3d print it....

You could make one up out of a hard wood like oak.
A saw, couple of gouges, round, half round and flat files and some sandpaper.

Set it up and make sure it works then have it scanned and printed.

Would be a fun exercise and we could all learn by your experience.
Off you go!!

I think that would work for a lot of people, but my workshop has more 'scrap' metal and plastic than oak.

I have an original on which the base of the stem is worn and two replacements in delrin you can have FOC .Also you can have the pawls and their springs which are in good order plus the arm spring .My drum itself is worn and heavy so not worth posting to you.
PM me a phone no. if of interest.

These Gibb 7STA are well made but have a rather a strained action for something that in their day won a design award.They were the standard winch fitted to Super Seals and at least the early Parker 27 s for lifting the keel .
After the turns on the drum the line is taken round the strong post and then back as it rises to the tailing groove .So the red pawl/dog is shaped to keep the line down and on the post before it rises .Had the post rotated or been fitted with a sheave/bush it would have avoided the high friction that arises when under load.
The red pawl/dog is held in position in the groove on the drum by a return spring in the base of the post .
To avoid the friction we used an adjacent winch about 150mm away to turn the line before it rose back to the groove.
We replaced our 1987 Gibb with a two speed Antal to lift the heavier keel found on the later Parkers.

It does seem a bit 'strained' but I can see it's a simpler thing to make than other ST winches with the stripper arm on top.
Self Tailing winches are not a cheap upgrade I've discovered!
