I have the final two pieces rough cut and starting to think through how to attach. Also thinking through where the transition point will go on stem. I mocked up a few scrap pieces in these photos. It looks like the transition should be a little further down the stem so I ensure I have enough meat left on ply where it will be fasten to stem. I had envisioned the transition point to be approx where I have it in pic...but I am thinking further down would be better.

Here are a few pics of how I did it on a Malahini.
I basically just picked a spot and went with it!

Thanks. Those are helpful pictures. Is that 3/8” ply? I just started the fitting last night. It’s challenging to bend it around the stem. I tried placing a few screws in to hold in place and trim but it just popped. I figured out how to clamp it. But not sure how I’ll do the other side.

Maybe a two man job. Or maybe I should call in an expert... 🤔🤣not sure. (That’s my humor)

All feedback welcome!

Yeah, the bottom planking is 3/8. It is not easy to make those tight bends on the bow. I used boiling water and towels to help convince the ply to bend. Below is a link to my build page that shows how I did this on my project. Best of luck finishing up the planking!

Your boat looks amazing. Thanks for all the tips.

Definitely felt like a wrestling match last night. I'm sure I work through it.

The boiling water/towels trick really works. That's about the only way you're going to get the 3/8" ply to bend in that area.

Thanks

I kinda had to hit pause button and plan out some steps.

I can get the wood to bend. My fear is getting it to stay on the frame or even cause a breakage to frame once its attached. There will be a tremendous about of torque and tension on the frame from the ply.

So...here is what I am thinking.

I can back the chine from frame 3 to breasthook with additional mahogany and beef up stem with another 3/4" ply on each side. This will accomplish two things. 1) give me more surface area for ply and frame to come into contact with, 2) I can use longer screws.

I am thinking through a clamping system that will work for both sides. Shouldn't be too difficult, just time. Of course I have do to some more fairing to battens and stem...learned that after I fit ply...will make some progress this weekend, but it's a busy one...soccer, dance, pool party, and building pine wood derby cars with the girls. :D will be a fun weekend regardless...

Hello Everyone,

I have not made much progress since last post. Still concerned about attaching plywood.

On the one hand I reasonably confident that I can get it glued, clamped, and screwed on flush and tight. But still concerned it will pop off once I remove clamps. Should I be concerned???

Can anyone comment on whether or not the plywood can be steamed? I am using 3/8" okoume marine grade.
Was also considering scaring backside with saw blade 1/32" to 1/16" every 2" - 3" to take some of the tension out of it.

Any experience or creative thoughts on this?

Thanks,
Eric

I didn't need to, but many here have used towels and hot water to help bend the plywood. I think once it is screwed down and the epoxy has cured it is not going to pull itself free. As a matter of fact, I had to remove one of my plywood pieces. It was extremely difficult.

thank you Bryan. I did need to use the boiling water to get it on there. I've come so far, I would just hate to have it fail at this point. So if there is any other steps I could take to minimize a failure, that would be good to know. I'm sure there is a fix if it were to pop off, but definitely don't want that to happened.

Once you get it screwed and epoxied down it's not going anywhere. The screws will hold it tight until the epoxy cures.

One month later...I am well versed in patience and persistence. Glad to have this step done. I really struggled to fit last two pieces of planking. Needed five hands. Oh well, done now.

Mostly happy with results. Not perfect. But it’s screwed down flush an tight with frame. I will fill in the gaps and get to glassing.
