Loos gage for multiple wire sizes

[yelkenli]

Does anyone know if there are wire tension gauges for multiple wire sizes, specifically the C27 shrouds, which are 3/16 and 5/32?

I see the 90 Model B but this will not measure the 5/32 from what I can see.

I don't see any other manufacturers in the same price range.

I suppose I can do that by feel. I hate to buy two gauges.

Loos gauges are the standard. I assume the smaller wire is for the lowers. Tension there is a little less critical condition than on the uppers.

Feel would work if you have finely tuned thumb. I think I would try to extrapolate the readings from the larger wires to the smaller wire.

For example, if 100 lbs of tension on the 5/32 wire is 25 on the gauge and 30 for the 7/32 wire, then that would be a 20% increase. Assuming a straight line relationship (which it really isn't) 100 lbs on 3/16 wire would be 20 on the gauge.

Bear in mind, I just made those numbers up because they are easy to work with and I have no idea if they have any relationship to reality. Note also, the relationship between wire strength of different dimension is not linear and not based on diameter, rather strength is based on the cross section area of the wire. For the level of precision needed for tuning the mast and the small difference between the 2 wire sizes, it is safe to use diameter.

There are several scales on the PT1 and PT2 gauges. You just need to get the one that works for your boat…unfortunately, it looks like you would need both…

I think once you gauge one and get a feel for the tension, you could do the other ones by feel.

Maybe you can borrow one or both gauges from someone here, and pay the shipping both ways. I have one gauge, but I'd have to see which one it is.

The gauges are sized such that every boat requires at least two models to tension the rig.
