I usually work alone. Working the whole side as one big panel won't happen. I put the first sheet, then clamp screw and glue the backer piece. Once the glue is set, I bolt screw and glue the next panel. The bolts help bend the new panel to match the rest of the splice. Bolts are removed and the holes filled.

I did the same as Bill. I found that when I was fairing the panel later that the joint was amazingly fair already. Very little tweeking needed.

Hi Bill.

Do you by chance have a pic with the bolts installed? Trying to envision the steps you are taking.

Thank you.

Sure don't have that picture. It will depend on your bend. Usually I would start in the middle and work out.

I used both methods on my boat. The method described above by Bill is much better.

I joined the sides using fiberglass tape before mounting them. You have to keep them flat and from moving a PIA by itself.

It also takes a long time, I did both sides so I had to wait for the epoxy to cure before I could move it. I usually only have short periods to work on the boat, using this method there was a few minutes and then I was done.

I found that the real problem was that you now have a large area to fair. Although the glass is thin and there were no wrinkles there is fairing to be done along both sides of the tape.

I used the method described by Bill on the deck. The butt joined perfectly, I don't think there is any fairing to do but if there is it will just be one line where the join is.

The deck where is did the join has quite a curve in it, the wood will bend no problem.

So I was thinking I could clamp a scribed 2x4 against sheer ply and a block on the back side. Seems to hold the backer piece in tight.

Repeat with second sheet once first sheet is secured / glue is dry.

epiziali: That look like it will work out fine.

What a great method, works on both sides of the joint and both sides of the boat. This goes into my notebook for my build :)

I am not seeing much specifics on screw pattern for backer. The book called for every two inches. Is this at the seam only? Or throughout? I am almost inclined to Glue and use no screws. The screws are holding two pieces of 1/4 inch plywood together. So not much there for the screw to hang onto.

That's sort of the way I thought about it, too. Granted, my boat is smaller than yours, but I didn't bother with screws in the butt blocks on the sides. After 4 seasons on the water, no problems.

I wanted to loop back on my butt joint. I think I ended up doing what Bill does. The blocks were an effective way to clamp the backer and hold tight to screw the sheer into. But at the seam, I needed more clamping strength than I could get out of my blocks. So I ended up bolting.

Bill, wondering if this is what you meant, see pic. Also, what did you use to fill holes. I was thinking I would use epoxy and dowel.

Thanks,

Eric

I think I just used 1/4" bolts and filled with thickened epoxy. I was always planning to paint anyway.

Thought I would post a few progress photos. Things are moving along. And just getting to final two pieces for bottom.
