I've broken the rules on wood movement on projects and have regretted it. My advice is to not break them. Tests would be sensible. I see a lot of links on a google search for plywood masts being...

I'd expect a two layer lamination of quartered fir and flat sawn paulownia to cup as well as bow and in the process maybe twist some too. In my experience this can happen while the glue up is in the...

Here's an interesting video from Oregon State showing unbalanced construction. Warp happens in just a few hours.

The three layers with outer veneers and a quartered lumber core is the traditional practice for making laminated components. There is a good chance for warping when laminating two different species...

Looks like nice stock! The fir price you got isn't bad. Did you buy the okoume yet? That hurts too. At least the cost is spread out over the life of the project so you can do it out of pocket...

I know, I know. Things can take a while when you don't know what you're doing! Got holes drilled in spars and coated, screw holes filled, rudder box assembled and mounted (that was a bit of a...

Thanks for the reply. I had typed the message and then somehow lost it and then re typed in a rush. Doh! I meant the deadeye for the halyard at the top of the mast. I found some photos where I...

Thanks for the link and information. That manual looks pretty complete! I'm uncertain about the location of the deadeye for the down haul. The rigging website says to put it on the "back" face of...

Hi Mike. I used West System on my GIS. I put a green coat of unthickened epoxy on every surface that I epoxy together. I don't wait for any length of time after the green coat as it usually soaks...

Thanks. I was thinking along the same lines as you, but think I'll through bolt what I can. Maybe screw on the cleat for the halyard.

Getting ready to mount some hardware. Should I through bolt the deadeye to the mast, which is what I was planning, or is screwing it in place adequate? Likewise for the down haul cleat?

Thanks! ...

Very exciting! If you waited to coat, you could even sand off the stain to even it out before reapplying. If you decide to tint the epoxy, I think applying it untinted initially might be a good...

While the epoxy coatings might help protect the stained surface, I think you might have better luck getting a good stained finish if you glue up first and then epoxy coat after assembly. This...

I had trouble getting everything in my exterior panels all in plane and smooth during glue up. Just wondering about precoating before glue up and what happens if you need to sand stuff out. Think...

I've seen the system 3 stuff around but have never tried it myself. Looked it up and the page I found said the silver tip is for wetting out glass, coating etc. and down to 35F without blushing...

Thanks again. I've read about the sealants and peoples opinions about them. I don't have any experience at this point to say how they differ. I was thinking of epoxy as well. Hoping it'll come...

Thanks for the info Dave. I need to sit down again and make a list. About ready to mount the other hardware. Any recommendations for mounting and sealing the rudder hardware through the transom...

I'm getting closer to ready for the Goat together. I' purchased all the lines and the Rss sail from Duckworks this spring. At the time I hadn't figured out what I needed for the blocks so I still...

I used the West System epoxy because it was what I was familiar with. With the fast hardener it works down to 40F. If your garage isn't heated then the lower temp stuff opens up the window a bit to...

Hi mxp. I'm just up the road from you in Boxford. I was attracted to the GIS for the same reasons as you. If you'd like to get a sense of it in person, my boat is sitting here in the yard most of...

I once had a home roasted and brewed coffee and it was absolutely the best cup of coffee I ever had! I could smoke a brisket and bring it for sandwiches etc. if that is something that folks would...

I agree with Dave that the scarfing isn't all that tough. I've never been to North Dakota, but you're relatively close, compared to us here on the east coast, to the source for the red cedar and Doug...

Looks great! Congratulations!

Jack and I took the boat out on the Piscataqua/Little Bay yesterday afternoon to Fish for stripers. No fish but it was nice to get out and see how the boat handled the current. It was a beautiful...
