Title: which Loos gauge?
Post by: Eddy on June 03, 2015, 07:38:24 AM
I need to check and adjust the standing rigging. Would like to know which gauge you are using and how you like the operation. Thanks.

I'm no expert: I use the regular Loos gauge. Came with the boat - cheaper model, seems to work fine for general adjustments.  It isn't a fine-tuning tool - I would not use it for tweaking a racing rig - but it seems to get you in the ballpark.

May be worth talking to a rigger, see what they use.  Certainly something I would like to learn more about.

What wire sizes does the gauge you have measure? Defender has the better gauge on sale now.

I just ordered the Regular model 90 B, which states it goes up to 9/32" wire. (the model is A smaller) Will let you know if this is the right one. I may have it in time to use it this weekend

I never had much luck with the cheaper style.  Too difficult to make repeatable measurements, and you can't just read it as you adjust.
I always borrowed one of the (much) more expensive PT-3s.  Wish they cost less:(.

do you recall the wire sizes of our boats? I was hoping the pt2 would cover it. Thanks for the input

My owners manual says the wire size is 9/32"

On mine, the outer shrouds, forestay and backstay are 9/32", and the inner shrouds are 1/4".

Ed (Dolce) I hear you on the repeatability of the measurements - much better way of saying things.  I found with practice you could get readings similar enough to see if you have a problem or not - if the tension was roughly right, and if the tension is similar across the baby stays, but not much more than that. But you could not make precise measurements or adjustments. Definitely batter than nothing, but not for fine tuning.

I just wanted to report that the 90 B model is the correct gauge, and it worked just fine for me. I feel much better about the rig tension now!

I bit the bullet and bought the pt3 gauge and it arrived with no scale attached so I had to send it back. I've gotten the replacement and am going down this weekend to adjust the tension with the gauge and then sail the boat to mdo any final adjustments.

I bought a new Loos standard model 90 on EBay last week for $40.00 with the "make an offer feature". It came very quickly. I plan to try it out tomorrow.  I think $40 is a good price? The seller has one or two more left in inventory.

What should the tension be for the uppers and lowers, and how do you tell if the front/rear stay is too loose?
