Yeah, good work, Patrolman.

Ghostshaper, channels definitely don't fill up with resin, except if they're poorly glassed. And if think they're slow, you're in for a treat when you try a good one. It feels like all that lateral force is translated into forward propulsion.

The glassers and sanders must hate doing these boards.

Impressive. I've always been afraid to even try to glass channels.

@tweak808 posted that he puts like a cheater coat of resin in the bottom of the channel and lets it kick a bit before laying his glass.Then he tucks it in to help/encourage the glass to stay in the bottom of channel while laminating.

Yeah, twinzerfan shared that one with us some years back, but I'm still afraid.

I'm going to do a tail patch with 3 oz glass. Then I'm using poplar veneer over that. That'll be tricky. I've never seen anybody do it. Josh Dowling would do his timber boards but when he did channels he would leave that area without wood. I figure I'll take coordinates, split the veneer, and maybe have to do a long vee cut. We'll see...

Epoxy has that stage where it's kind of gummy. I'm going to be nursing the board at that point trying to squish everything into place. It's the tips of the channels, where they come out the back that worry me.

I would think your laminating game (timing) would need to be on point,

I've often contemplated how I'd do veneers in channels. Right down to routing in 1/2 depth "stringers" to form the exposed sides of the channels prior to shaping. I've just never been brave enough to try it.

I had thought about bagging some soft 1/16" balsa on the channels, then sand off the top and bottom so that it only covers the sides. But I also wanted to avoid further locking up the flex in the tail. I decided to just paint the channels. Will glass tail patch then see how to fit the veneer. I'll post pics before bagging.

Lots of wood, lots of channels...but no wood channels. Wood tail blocks on channeled boards. There was even one photo where he had channels and then set blocks of wood in the channels but no photos of finished products.

I did like the amount of experimentation he's doing. Thanks for pointing him out.

One variation I was thinking of was cork. Glue the sides on, trim to the "bottom" face and cover the seam with your veneer or plank.

It seems to me the channels themselves would lock up the flex factors in the tail. I-beam style.

I've thought about trying to bag channels w my bottom skins. I'm going to try hand lamming the walls of the channel first, cutting the skin along the ridge of the channel, then vacuuming down the skin so it lays flat in the bottom of the channels.

Giving it a try...

For some reason after cutting the veneer the left 3.5" wide panel shifted about 1/4" to the right. You can see the bottom of the channel in the pic. It was like cutting the veneer released some tension that was in the wood. Before I bagged it I taped it in proper alignment, but then the veneer bulges further up. It's now in the bag and seems to have pulled down but it's under the bubble wrap so I can't really see and won't know until I take the board out of the bag in 6 hours ( I use slow hardener when I bag).

By the way- I painted the sides of channel with tempera and then put a 4 oz patch over the tail before bagging the skin. Glassing channels is interesting I figured out while doing it how to use two squeegees, one to hold the cloth in place, the other to tuck the channel. If I didn't do that, when I tucked one channel the cloth would pull out of another.
