No doubt. My Missoula buddy has some Sawyer V-lams he runs on his drift boat...those are super light.
When I got behind those sticks a few weeks ago, I realized immediately mine were too heavy. My smokers are old school and a bit heavier...but still lighter than the ones I made.
I'm thinning the wood in the blades down to 1/8" thick and researching some fiberglass/carbon wrap options.

Mt4runner-
Do you epoxy flow coat your grips?

I went for 3/16" edges/tips with glass wraps.
Spines are 1 5/8" at the neck tapering to 3/16" at the tip, and tapers from whatever the center of the spine is to 3/16" edges.

1/8" seems too thin. Not much distance between the glass/CF faces--and distance between those two shells is where your monococque strength comes from.

Yep, always have.


Have heard the arguments to keep them bare wood, but I'd rather deal with slick epoxy/varnish than with potential doug fir splinters.




I just tried hockey grip tape on my kayak paddle for cold weather paddling...it was awesome. Also added some grip wax, and the wax stuck better to the cotton than it ever did to my bare paddle shaft. I'm going to give it a try on my oar grips this spring.

Hickey grip tape is great... unless you are paddling/rowing barehanded and haven't gotten those season calluses. If you still have soft/dry winter skin then the abrasiveness of the hockey tape can rip your thumb raw.

Thinking I might try fake cork bike handle bar wrap on my oars. Its soft and slightly forms to you grip over time - not sure how it will hold up to continuous river use.

Any thoughts on using the baseball bat tape?

Agree, got the blister on the back of my thumb on my right hand to show for it.

May trim the tape so only my middle-ring-pinky fingers lie over the tape.

I don't see it as much of an issue on oar handles.

Hey guys,

Generally, my oars turned out pretty good, but I am also having issues with swing weight. Basically, they balance great on my clackacraft, but just ok on my raft frame (which has approximately 6" shorter beam length that the clack, I think). I think I should have removed more material from the blades to make them thinner and less broad. If my oars break, I think it will be at the wrist right before the blade. Otherwise, the flex, etc. is great.

Do you guys think trying to remove the epoxy/fiberglass from the blades is a nonstarter? I figured it might be better to just make another set in the end.

Here are the best pics I have:

Varnished grips were too slippery if I had sunscreen on my hands.

I did a few wraps of hockey tape on my handles when I was on my Main trip so it was under my middle-ring-pinky fingers and really liked it.

Go for it, what do you have to lose?

I recently found that a big 7" angle grinder with a sanding pad and 60-grit makes FAST work of removing fiberglass. Do it outside/with a respirator/with a vaccum/dust collector!!

From what I could see of your pic, you do have material you can remove without losing strength.

Do this like I did:

More oars:
My friend wanted some gigantic 11'-6" oars, so he's getting gigantic 11'6" oars!

I found some more gorgeous tight grain old growth douglas fir. Previous oars were clear vertical grade #2. The guy at the local sawmill recommended I try out select, which is a tight grain flat-sawn wood. Perfect for this use. Once I resawed it and rotated it 90° it became vertical anyway. haha.


This is the absolute most beautiful tight-grained, straight-grained wood I have ever seen.



He also wanted counterweights, so I added #8 rebar, which is what he got!
Used a 1" cove cutter in the shaper and cut 1/2" deep in each side.

#8 bar is 2.167 lbs per foot, so I cut it into 11" sticks. Each piece of rebar got epoxy coated for rust resistance, and then bedded in thickened epoxy.

Shaft blanks are clamped with strong backs for straightness. I'll taper and round the shafts in the next couple evenings and get them ready for blade gluing.

That’s freaking brilliant, with the rebar!

I’ve always had trouble lamming up wood, end up with a cup in it. That clamp system shows me how I should be doing it!
