Is there a correct way to adjust a stay using an open barrel turnbuckle... I may be over complicating this but the more I played with tightening the backstay, the more confused I got.
Thanks

Not 100% sure what you're asking. In general, you want the turnbuckle body to turn and the shrouds to 'hold still'. The further the threaded studs protrude inside the turnbuckle body, the tighter the shroud.

Most shroud fittings will have a flat that can be held with a small crescent wrench... Hold it (them) while you use a marlinspike, crescent wrench, (whatever) to turn the turnbuckle body in the appropriate direction.

Ideally, the threads on each end of the turnbuckle should be pretty evenly inserted in the turnbuckle body.

Note: Stainless thread should be lubed before turning or they can gall (seize).

Clam is correct.

I use a pair of vice grips gently on the lower fitting to prevent putting rotation torque on the mainchains...this prevents them from breaking the seal with the deck an letting water get in. A foot on the vice grip steadys it.

Then I use a couple of crescent wrenches...one to hold the shroud and one to turn the turnbuckle. After a few trial-and-errors you will get the hang of which way to turn to tighten/loosen.

I use Never-Seize in a little tube on the threads.

Also, I use monel wire to secure the turnbuckles instead of cotter pins. It eliminates snags and cut body parts. My airframe buddy, Travis, taught me how they do it on planes.

After adjustments, what do you guys use to cover the turnbuckles? Nothing; tape; the hard PVC tubes??? Thanks!

I use seizing wire to keep the turnbuckle from unthreading... and cover any sharp pointy stuff with rigging tape.
