Topic tags/keywords: veneer canoe paddle epoxy tightbond

I’ve been making canoe paddles lately with some intricate wood patterns. I’ve done it using solid wood, but there are a few patterns I’d like to try on the blade that would be easier if I simply put a veneer over the blade (think marquetry ). The blade is mostly flat with a slight convex shape to it. What’s the best way to attach this to the paddle? I don’t have a vacuum press, and I was thinking maybe support the bottom side, then lay the veneer on the top side, and weight it down with some sandbags?

I was thinking of using tight bond 3, but if the blade isn’t completely smooth it might be better to use some West System epoxy?

Maybe Paul (Shipwright) will be along soon to discuss the fine details of applying veneer use a veneer hammer. I know he has a blog post about it and he’s a true expert.

Good Luck!

Since it’s going to see a lot of water use, I think it’d be better to use epoxy.

I don’t think that sandbags would provide enough clamping force.

As far as gluing it up, your best bet is to make a mold that fits the paddle curve exactly and use that to clamp it down to. I would think something like a thin layer of rubber/neoprene would be enough to smooth out any imperfections that would arise from making the mold to it. Then just clamp the hell out of it.

I have seen videos of the Bentley factory and they just use wide tape to hold the veneer in place until it dries.

Section I reference starts at 5:12

They do use a vacuum system though. I guess I would too to insure best adherence.

The Bentley video is just using the tape to hold it roughly in place before it goes into the press, I don’t think it’s doing much clamping on it’s own.

I don’t think I’m able to make a mould that matches the paddle blade, and ideally I’d like to do this on more than one paddle but they are always different.

I wonder how much clamping pressure epoxy really needs?

Canoe paddles aren’t that big so why not just make yourself a vacuum bag with some plastic sheeting and a wine bottle air extractor? That’s what the skateboard kits use. OSI Quad can be used to hold polyethylene plastic together or old-fashioned 3M window sealant for cars.

You’re looking at a max cost of $20-$30 to do it.

It’d do it with epoxy and clamps, pretty much like Jeff (jmartel) said. Should be easy.

Thanks for the thought Herb by you can’t use the hammer veneering technique with marquetry. It also only works with hot hide glue which isn’t the best for this use.

Paul, that’s why I defer to you. The closest I’ve ever come to doing anything with any kind of veneer was installing formica on cabinet counters back in the 60’s.
