Strongback idea....

[Chalk]

Thinking about building my Phantom like this, Thinking about finishing the outside prior to flipping (one flip)....Thinking it would be a cross between a jig and building it on the floor...If I had any unfairness in the bottom, the I-joist would allow me access to adjust or fix the problem.....What do you think

Jim,

That is similar to the way I built my Phantom. you can kind of get the idea from this picture:



That building dolly looks almost to high. It would be hard to reach across the Phantom to sand etc at that height.

BTW, what boat is that... I like the lines.

Cary,

I was planning on using the 12 inch I joist, that would put the Keel about 3 foot +/- in the air......

I think it is a Palm Beach designed by Nelson Zimerman...Builder site Palm Beach

Jim,

One other quick comment... The dolly will get wet as you sand fair and paint the bottom. You will need to make sure that the I-beam will not separate when it gets wet.

Had not thought of that, OSB + Wet = swollen .....trash another good idea ...What size of 2xs did you use? Did it stay straight?

[Eric]

How about draping plastic on them? or coating them with epoxy? maybe too expensive.. I like the idea of the beams, real straight and stable. Ther must be a workaround, great idea though

Chalk, don't despair. Those I-Beams will outlast your boat project by a healthy margin. The OSB resins and waxes are all exterior rated. The stuff may gray up a bit with water and UV, but the strength abd stability will remain for years. Don't forget, they build houses in the rain too.

You could also put on a few thick coats of enamel. That would seal out the water and probably be strong enough to not scrape off if the boat was dragged along the surfaces. If you're very worried about scraping, you could always put some very low nap carpet on the top surfaces.

Thanks for the ideas..gonna have to price them out......

Jim,

I like the idea of the beams you just need to make sure they survive moisture.

I used 2"x6"x8' boards to build my dolly. You can get an idea how I built it from the pictures in this post.

The simple design was serviceable and easy to alter. I used the same dolly to hold the boat upside down and right side up.

Let me know if you want more details.
