RE: winding sticks

I learned to sail 65 years ago, and have been building boats almost as long, but never heard of a winding stick. -Wes

RE: winding sticks

Robert Meyer talks about them with his Peeler build. I think they are for checking for hull twist but not really sure???

RE: winding sticks

you beat me to that question!  I did a quick search and got some info.  Not sure why a good level or straight edge is not the same.  Hope someone can clarify.

Here is a photo of winding sticks showing their use.

You can make your own sticks easily - paint each stick a contrasting color so that they show any twist of the hull when sighted.

Ahh!  Now I got it!  Thanks! 

RE: winding sticks

I'll be darned. I use that technique on every boat but never knew it had a name. Unless you have eye problems or bad lighting, any old straight sticks will do, though. They don't need to be contrasting colors. -Wes

RE: winding sticks

I use plain old sticks and set them a couple feet from the bow and stern - square them to hull centerline, and then duck & squint to see if they line up. If not, then I "wind" the hull - as in counter-twist it until the sticks line up. Do this before you tack glue! 

RE: winding sticks

I used the skids that came with my Peeler kit as winding sticks. (just make sure they are absolutely straight with no warp in them - mine were) I usually just use whatever cut offs are at hand. Be sure to take many different sights bow to stern. I did paint up some contrasting sticks one time - but found they had warped on me next time I needed them.

RE: winding sticks

I have a question on the subject. If the work base is not 100% level but the (comparison) winding sticks match up,, is that ok??? Should a bubble be part of the test to check that things are level too? I guess if your work base is level all is good. I answered my own question. Thanks everyone for your comments and help and have a Happy New Year.  Ken (klitz)

RE: winding sticks

Ken,

Nothing needs to be level. You are comparing one part of the boat to another part of the boat, with no relation to the floor or building base.
