'Handles' for a bottlescrew- can you still buy these somewhere?

[Kelpie]

The new boat has a rather simple but effective backstay tensioning system, which is roughly similar to this:

On close inspection it seems to consist of two stainless 'handles' that just clip onto a normal bottlescrew (the one in the picture I linked to is a little different and doesn't seem to use a standard bottlescrew body).

I'd like to source another one to use on my removable forestay, but when I google for backstay or forestay tensioners all I get is hundreds of poundsworth of swanky race equipment, which is not what I'm after at all.

Please excuse the thread drift but can you tell me what the ring that is u-bolted to the backstay is for ?

Thanks,

No idea- it's not my boat! I haven't really got to gruips with uploading my own photos so I just pulled that one off Google.
At a guess, perhaps it's for stowing a dan buoy?

I'm confused, a bottle screw is used to tighten rigging to the appropriate tension. A screwdriver shaft is used in the hole in the bottle, twist and tighten, not a handle. As for the two things on that stay I have no idea what they are, the bottom one looks like a lever but it won't tighten anything.

There are three things. The upper lever is unfolded, that's the one that keeps the wire and upper thread from turning. The other is on the central part of the bottle screw, folded down in the photo. That's the one that rotates. To the OP, sorry not seen one like that for many years.

I suspect the ring above the bottlescrew is for holding the lower end of a boathook.

I use "handles" to tighten the inner forestay, works quite well.
These ones are called "Varivant" and are designed for Hasselfors (now Seldén) all s/s bottlescrews.
Varivant are still available here in some sizes, but unsure for how long. Seems Seldén no longer makes all s/s bottlescrews smaller than 1/2" (7mm stay?).

To answer the OP's question are these "Backstay Turnbuckles, Jaw & Jaw" the things he's looking for ? http://www.westmarine.com/c-sherman-johnson--backstay-turnbuckles-jaw-jaw--P002_065_008_512

And to persist in my thread drift, can anyone tell me what backstay boathook rings are called and where they can be found ? (Yes, I did try googling "backstay boat hook rings").

I've got one of those "boat hook rings " which fastens to a stay. I've never seen one in a UK chandlers but they are ubiquitous in Holland, which is where I got mine.

I fou

nd this old S&S design from the 60s,

 

[Kelpie]

The boat is an S&S, so I guess that's where the device comes from then.

The two 'handles' are made from a very small piece of pressed stainless sheet, I cannot see how it would cost more than about £20 to make something like that up...

I may 'borrow' the backstay one and stick it on the forestay...

S&S ( Sparkman & Stephens) are yacht designers not manufacturers

 

[Kelpie]

Well yes I know that, but I'm guessing it's no coincidence that another S&S design ended up with the same device. Now to track one down somewhere...
