Progress on giving the old oars some TLC

9.5'ers got more glass on the tips. Time to flip the Oar rights and wear the edges on the other side.

10'ers got completely sanded below the wraps and all new glass tips. That's 6 layers of 6oz glass. It's very clear if you wet out the glass well. There's a slight greenish hue as your layup gets thicker. Think window glass.

On the bare wood, I'll squeegee on epoxy and use a heat gun to warm it and soak it into the wood.

Everything gets a couple coats of catalyzed spar varnish.

...and I launch on the Main Salmon 6/28. Oh, and I'm out of town this weekend 🙂

Sanded off the old varnish.

Skim coat epoxy. I use an old credit card or hotel room key to squeegee on the epoxy, and fill cracks and low spots. A brush will fill a consistent thickness on top of high and low spots indiscriminately.

Made these 20 years ago. So light they don't need a counterbalance.
Pine core wrapped in ash. And some other hardwoods.
Favorite tweak is the oval grips,
like a kayak paddle.
Used a 2in router bit for the shaft.

Rob, those are bad-ass and beautiful. I love the idea of the pine core with the Ash wraps. Put the hardest, stiffest wood at the outside where it does the most work. Pine just needs to fill the space.

Varnished and ready for the Main Salmon next week

Probably the nicest finish they've ever had.

Helmsman spar varnish thinned with naphtha and a little enamel hardener added to catalyze and harden it.

The worst blade in 4 days. This amuses me. Back for another 14+ years

Let's get started.

Buddy wanted a set, so I told him I'd help. Then two more guys wanted oars. We're now up to four sets of 3 oars.

Bought some gorgeous cvg Doug for at RBM lumber in Columbia Falls, MT, along with some spruce and cedar for blades.

8/4 x 6" x 10', and a couple of 8/4 x 8" x 10'.
I can easily get three shafts out of the 8" wide boards; probably 2 each with rips for blades or to laminate into an additional shaft in the 6" boards.

Not entirely sure what I'll do on the square top...probably 3" square, which will require a 1/2" ripper glued to each face of the 2" board above the rope wrap.

No need for oar rights, just like a kayak paddle.

Waiting for a buddy to return from a trip to use his shop to rip the new wood to width, and dug on my old computer to find the build pics from my earlier sets.

Oldest set--taken 14 years ago next week (7/18/04). Forgot how tedious it was when I hand-planed them.

The epoxy/fiberglass/ash spline across the tips is visible before the tip of the oar was trimmed.

"newer" oars under construction in 2011.

The older oars had 7 years with only a tung/linseed oil mix. They got a fresh sanding and epoxy coating at the same time I was epoxy coating the new ones.
