IMHO, you have a seriously cool thing going on that I'm sure has crossed many peoples minds. How can you not like speed tubes?

I hope you get the time to share what you are doing, I'd be all over it!

Showed pix of your boat inside the houch and told my new Nanai'mo bride I should be able to bring me boat inside in front of the Plasma screen and fun loving cats just like other boat builders get to do......

We could even cut back on Glenlivet, once she sees how much fun the glue fumes are.

.....Oh well...no joy.

That's a great looking log house you have there mate.

Cheers

Lol!!! Good try on getting permission to drag the boat into the house, you would have loved it. It just makes so much sense.... mind you not one female has ever agreed with me on that point. Funny thing is I do have a fully equipped shop behind the house but couldn't get the right temps and humidity needed for the glueing process.

As for the house. Thanks. I'm still finishing off some trim work here and there, I've been cobbling the place together for the past eight years as time and money allow. I built the place with minimal cash and maximum sweat equity.

I live off the beaten path so property is reasonably affordable and if you're crafty with some good helpful friends, you can pull off a roof over your head with a bit of effort.

Lastly.... am I to understand you have a Nanaimo bride from the island?

Yeah she was born there, I figured a Canadian bird would be more comfortable around my guns.

Here's my boat rolled up on the way to the living room when the chick was away visiting. I sat in her for a week watching Gillian's Island and getting pissed on rum as I laid out the deck plan.

Cheers

Well done on the island girl, they tend to be reasonable. You should be fine.

And thanks for the tip on the approach to a proper layout. I have to figure out how to manage my remote steering and throttle control. The Gilligans Island and rum method should speed things along for me.

I'm going to try it.

Been away for a few days working on the mainland earning my keep....

I have survived and will be focusing effort on completing the transom support attachment bits and building a simple "console" to house my newly acquired remote steering hardware.

All planing and layout will be under the suggested "Squid Boat method" described above.

About to pour rum ( truthfully...more rum...) and surreptitiously download Gilligans Island episodes to prepare for the task at hand. Serious business....

Brain food.

It's true.....

Bodge · 28 April 2016, 23:40

Progress....

Home for a bit so I tackled the transom issue. Made and attached the riser, backed it up with marine ply glued and screwed on both sides. I can not see this coming apart so I can stop worrying about that and move on to the thrust board issue.

It would be nice to tackle the trust board from both sides but my floor is in really good shape and I have just enough room to pull off a repair as is. Admittedly, I don't look forward to the preparation required. The thrust board is fine on one side so I will over lay a large patch on the good side with a healthy overhang., screw down a piece of lathe over the hypalon that attached to the wood bit to keep it from lifting. Replacing both attachment points on the dodgy side and also backing up with lathe. Should hold as all my new bits are over sized and damn near twice the thickness of the original hypalon.

Sorry for the crappy cell phone pic"s.....

Bodge · 29 April 2016, 01:05

The thrust board....

I have 9" of luxurious headroom to work with.

I have gained a considerable amount of respect for the people who repair these boats. I am beginning to see how one can find oneself in a predicament for what initially seems like a straightforward repair.

I can see how it takes a certain mindset to get through it all in the correct fashion. More power to you people.

If my boat ever goes in for repair, I promise to happily pay (one of you....) with a smile on my face and a hearty handshake.

Lastly, in the second picture a half moon shape can be seen where the neoprene separated from the hypalon. Should I remove all of that or will the glue bond to the neoprene? I plan to sand about 1" past the existing out line and put in a replacement piece.

This could very likely be a dumb question and I probably know the answer but I am hopeful a glue guru will applaud the idea of "saving" the "heritage" piece of neoprene and gluing over......

No problems fixing the transom to the floor. Just plan ahead on what you will be doing and go slow and steady. It seems to have worked out really well and I have no fear bolting my engine on there. Use quality materials and you will be fine.

Also, I can unbolt the supports if i need to.

Are you planning on doing the same kind of changes?

berat · 15 July 2016, 10:38

I had a chain support at the connection point of the first and the second floor in my old sib 3.80mt Norisbot. I'll post if can find photos.
I'm not familiar about the soft bottom inflatable dynamics. But it seems to me a good idea to assist to lift the first 2 floor with this kind of transom support.

I'm sure a chain or straps would work as well.

I did it because of the age of the boat, perhaps it was not needed but I feel better that it's there.

I m planning to do the similar with yours, may be with some bounded aluminium profile. The first two panels are flexing and streching, thats too much disturbing me

There is a definite difference and I'm happy with the whole setup. I can air down the boat considerably when messing around and the motor stands vertical. Aluminum would be nice but I just used what I had at hand.
At present I have a 25hp hanging off the back but am looking for a 50 hp 2 stroke to replace it so I think the braces will serve me well in the near future.

I believe I am laying down to much glue when bonding...

Can I thin the glue? I am using a natural bristle brush cut down to about 3/4 inch. Would a shorter nap on the brush be helpful?

Thinning will weaken the bond.

Best tip for gluing: Try not to pass over the same area twice.

After all areas have had glue touch them, STOP MESSING WITH IT. Don't come back and go "oh, touch up here...touch up there".

Thanks Richard.

I'm afraid I mess with it...

What length of nap is appropriate for my brush?

3/4" length is about right.

I dip my 2" wide natural bristle brush, scrape both sides of the brush off on the slip of my pyrex lab beaker that I use for gluing (reusable, glue doesn't stick to glass), and that's the amount of glue I carry over to the substrate. I immediately spread it thin.

That's enough glue for about 5 square inches of coverage.

I spread it as long as the brush moves smoothly...once the brush starts to "chatter" against the surface, I dip my brush for more glue.

I use Zodiac Z7098 glue. Polymarine / Bostik 2402 don't spread as easily.

This is all very tough stuff to describe. Hopefully you can make sense of what I'm saying.

Avoid blobs of glue. Blobs are very bad.
