I wonder if using the etching solvent normally used before adhesive would accomplish the same thing Peter?

It possibly might do so.

From the Gougeon brother's book:

 

Plastic—Adhesion varies. If a plastic is impervious
to solvents such as acetone, epoxy generally will not
bond to it. Soft, flexible plastics such as polyethylene,
polypropylene, nylon, and Plexiglas fall into this
category. Hard, rigid plastics such as PVC, ABS,
polycarbonate, and styrene provide better adhesion
with good surface preparation and adequate bonding
area. After sanding, flame oxidizing (by quickly passing
the flame of a propane torch over the surface without
melting the plastic) can improve bonding in some
plastics.
 
This suggests that chemical effects could be similar. I suppose a test bonding would give the answer.
Flaming costs nothing and takes next to no time and comes with a recommendation from experts so I'd probably stick with that.
 
Cheers
Peter HK

I made the holes for the wiring chase pipe just a little over size.  Braced my pipe as best I could so a very slight gap was around the pipe and filled the gap with 5200 and used enough to make a nice fillet around the pipe on both sides of the bulkheads and decks.  I wanted the joints to be flexible.  That was my thought anyhow.  Seemed to work well and time will tell the tale.

Hi Russell, I have been following your build. I just wanted to say thanks for all the updates on your boat. I hope to build this same one here hopefully starting next year. Your post is a great encouragement! I am curious, what are you planning on using for an Engine? Good Job! Keep up the good work!

Thanks for the compliment. I have not decided what engine I will use at this point, my initial thoughts are for a 90 hp , but may consider a 70. Still a mountain to climb before I get there.

This is my first try at utube, I'll try to fix it---I think I fixed it try again and let me know, the vidio is 25 min long but it repeats itself about half way, My neighbors 11 year old made the vidio and I thought he did a great job.

Great video. You are fortunate to have enough head room to do that. I don't. When I build mine I will have to roll it outside to flip.

Thanks for the video. Very informative.

 

Don't know if your pucker factor was running as high as mine was watching all that but I suspect it was up there!

My fears were highest during the planning phase, hopeing all would work as I had planned. Once we started things went fast and concentration and action replaced fear, the cold beer after she was settled in her nest was the best! My three friends worked like a team and all went well.

I thought I'd update a bit, I'm getting ready to glue the sole and have been procrastinating wondering if there is anything more I need to do under there. Looking for a little advise from you all regarding the right goo for the job.My first thought is to use thickened epoxy, some folk say they use 3M 5200, and some say glue the edges and 5200 the stringers ect?

Wow.  I count 13 points and there may be a few hidden behind the lights.  I can't imagine what's hanging over the fireplace if that's collecting dust in the shop.  Oh yeah, the boat is looking very nice, too :)

It's 7 + 8= 15 total points non- typical, I shot it in Idaho 1967. I stalk hunted in the mountains around Bear Valley. Thanks for the comments about the boat.
