Offgassing

So first we headed out to the Buoy 10 fishery at the mouth of the Columbia near Astoria Or. Fishing was excellent! I love this place, but be prepared for combat fishing, as MANY people fish out here.

Coho here are BIG, comparable to a Chinook:



When we returned from picking up 50+ lbs of salmon per guy, it was time to get back to work.

OXFORD

All of the preliminary wood fairing is finished, and epoxy was the excitement today. SWMBO put her best foot forward on this, running the tipping brush (roller cut lengthwise and held with pliers). Roll some on, tip it down.





This really brought out the beauty of the structure of the wood, especially around the knots:



The temps eeked up a little bit after we got the sticky stuff down, which allowed some offgassing. This is where the expansion of gases trapped in the wood slide through the surface and create bubbles in the epoxy. This can be mitigated by doing your epoxy work midday or at the warmest part of the day, or by controlling the temp in your shop. Today it was a balmy 76F, so not like it was epically hot.

Here is a perfect picture of the off gassing bubbles:



It isn't anything we builder's cant mitigate, however. Just knock the bubble down with a finger, or if it has cured, a scraper, knife, or piece of sand paper. This will cause a small blemish, but since we are early on, there will be fairing occurring later and will be hidden with more layers of epoxy.

Ordered the rigger from www.clcboats.com a few days ago. Great people to work with as they are prompt to respond to questions and have very competitive prices. They are even having their oar supplier do a custom blade and handle for me (Dreher adjustable handles and a set of Apex Hatchet blades). I decided on the RowWing thanks to the help of Chesapeake Rowing and their expertise. Very good experience there as well, and they happen to be the supplier of CLC. Go get your goods from CLC if you can, it works out best for both of the businesses.

This is going to be one helluva sweet setup for SWMBO, I think she will be happy with it.

Thanks Eric for the information and the pics on the oxford....nice design. I built a scull last fall, well not quite built. I still have to put on the decking, the seat, outriggers and the oars. It's 22 feet and it looks fantastic! (built out of cedar strips, MAS epoxy shell). I see you had your outriggers done by a company, did they make the seat as well and was it pricey? If you could get back to me, I'd appreciate it. alexwolf7777@yahoo.ca

Love the design of the Oxford, it looks stable. Mine is "tippy" as hell, everyone tells me the outriggers will make the difference....sure hope they're right! Thanks for your Blog....I'm an ex ski bum instructor too!

All the Best
