Surecast project

[igotit]

You can use the dremel if you want but a cutting disk on an angle grinder can get the job done much faster and almost as accurate after couple of practice passes.

I started with the same dremel tool and when I switched to the grinder, I never looked back. Best of luck with your project

I used my angle grinder and cut off wheel for the teardown.
But this dremel will come on handy.
One of those impulse buys.....lol.

 

[sphelps]

The dremel is good for getting into tight spots that the angle grinder can't ... Ya don't use it all the time but sure comes in handy sometimes .

Gotta cut a few water drains then seal her up in paint so she can last a few year in the weather.
Soon ill beable to get back to the real project.

 

[igotit]

Got a little free time,cutting out stringers and transom.
I picked up so 1x6 deck boards(not treated)chose the grain carefully.
Ill use these for the stringers.
Im still a long way from installing the stringers.
Gonna try to sand n strip entire inside before monday.next week cut n fit stringers then glass by next week end,then transom and floor.

I love this dremel multi max,fast for rotted stringers.

Let the grinding begin !

 

[igotit]

Yep.....im broke and only have 1 grinding disc,2 used tiger paw sanding disc.
Ill try to trim away what i can.
Wound up working till 9pm....put a big dent in my plans.

Let the grinding begin !

 

[igotit]

The grinding and sanding.....followed by lots of itching begins.
Gotta do just about all the interior......the part we all hate.

 

[igotit]

Got 1 stringer valley almost done.
Probally best to remove all the old heavy mat....but i think ill be fine just sanding her down and making a clean valley for new stringer and matt.

ur cruisin!

Good start on the grinding ! I tell ya the best investment I made was springing for a full faced respirator ... Coveralls and talc powder are your friend ..
Any reason you went with the dimensional type lumber instead of plywood for the stringers ?

 

[igotit]

I thought about a full face respirator,but didnt have that kinda cash.somewhere i have a respirator.....but cant locate it.
I roughed it with a cheap disposable face mask type,short sleves and no powder....lol.

The wood choice.
This wood is alot stronger than the ply,holds up better to weather and water.
Figured id try something different.

10/4 ...
But do your lungs a favor and go find your respirator .. You could pick up an inexpensive one at Harbor Freight ..

A trick i use to keep the dust in check.
Spray the inside of the hull with a mist of water,airborn dust will stick to the water.
Just remember that water and electricity arent good friends.
Gotta use common sense.
With that said id still recommend a resp.

 

[igotit]

Im considering adding 2-3 ft of length to this hull.....but i teally hate adding more work to a project.

Uhmm you've got your strength ratios wrong. Dimensional lumber is NOT stronger than the same thickness of plywood especially when used in a vertical application. It does NOT hold up better to weather and water. The resorcinol glue used in making plywood helps deter water penetration except on the edges. Not saying NOT to use it just wanted to set the record straight for future iBoaters. It all boils down to how well you do the glass work. If it's done correctly and the boat is maintained and taken care of...You could use cardboard cuz water will never get to it!!!

My opinion,this solid board is stronger that a peice of ply the same size.
I have a hull from mid 70s,shes been sitting there gutted with only stringers since the mid 80s.
Her stringers are similar to the solid wood im choosing.
They are the only peices of wood that ate good in that hull.
In a water enviroment a solid peice will last longer than ply.

Strength
In my opion the solid board can bear more load than the plywood.
Look at house design for example.rafters and beams are always solid,not laminated ply.

I could be wrong about its strength though.

I based my info from here

That's talking about horizontal application. (Flat) When it's on edge plywood IS stronger. I guess it's been a while since you've investigated home and commercial building methods...
http://www.firehouse.com/article/10464551/behold-the-beam [h=3]Strength Characteristics of I-Joists Relative to Conventional Wood Framing[/h]
With respect to conventional framing (16 inches or 19.2 inches on center joist spacing), I-joists are 50 percent stiffer than solid sawn lumber. In terms of strength, for simple spans, an I-joist series with the lowest design values (PRI-20) can span to within inches of the strongest solid sawn lumber joist (S. Pine). In multiple span situations, I-joists have an advantage because solid sawn lumber in lengths greater than 20 feet is quite rare and expensive. Building dealers and I-joist manufacturers have substitution analysis software and can provide this service free of charge in most cases.

as you can see they only use 1/2" ply. You could make your stringers like this too!!! Some members have. Again, you can use what you want. Experience teaches plywood is a better choice.
