Has anyone out there built a TW28 or similar size boat using the cnc pre-cut plywood kit? Does using the pre-cut kit help offset lack of building experience? How much time does the pre-cut kit save? It would seem one botched layout would result in considerable lost time and material.
The study plans say the length can be increased by 10%. Is it possible for the CNC plywood cutter to supply a kit with this increase in length?

1. Not yet
2. Tracing to wood and getting nesting right can take time if you are not used to that kind of thing.
3. It will save some time but the ratio of time saved on a big boat will not be the same as that saved on a small boat where building the hull does not take as much time.
Mesure, check and mesure again before cutting your wood.

I expect the answer to this is no. The kits are meant for mass production and it would require a lot of one off work to make a kit for a 10% increase.Vincent Homer wrote:

None of the TW28's being built or finished are in the continental US - so none are made from kits.
Generally, the bigger the boat, the better idea it is to use the kit. It gives you a huge jump into assembly. It can also save money if you cut a large panel wrong.
Increasing the boat by 10% would exclude using a kit. We would have to redesign the boat.

It took me between 1-2 hours to measure, mark and cutout a sheet of plywood, depending on the complexity of the nesting on that sheet. See how many sheets are in the TW28 and that will give you an idea of the time saved by buying the kit.Vincent Homer wrote: How much time does the pre-cut kit save?

Where can I find more tech info on the System 3 Polyurethane paints? I did a google search and only found the System 3 epoxy site. What I'm looking for are instructions for reducing the paint so it can be sprayed and color charts for color selection, coverage per gallon, recommeded film thickness, recommended temperature for spraying and curing times, etc. I found some tidbits from the Boatbuilder Central site for the highbuild primer being water reducable and coverage at 350 sq. ft. per gallon but that was it.
Are the Stirling paints only roll & tip or can they be sprayed as well?
Trying to figure out what's required for putting a nice finish on the boat.
I'm going to see a young fella this week who's building a Farrier41 in foam & glass so I can see his vacuum bagging up close and in action. I'll be back with a whole lot of questions after that about bagging the entire hull of the TW28 inside and outside so be forewarned! *wink*
Thanks
Rick

Don't think of spraying Sterling (or any other 2 part paint except for System 3) without a positive air supply respirator.
A simple organic vapour filter cartridge will not keep out the isocyanates. (a cyanide compound). You WILL do severe damage to your lungs if you spray without positive air.
If you want technical literature on system 3 paints, go here for primer:
http://www.systemthree.com/p_wr_155.asp
and here for paint:
http://www.systemthree.com/p_wr_lpu.asp
But you have to register (free, no problem) first to get access to the information.

Thanks Evan
I was aware of the hazards of spraying these types of paints. I have a friend who's going through chelation therapy as we speak for heavy metal blood poisoning from painting cars without proper respirators.
Thanks for the links. For some reason they eluded me.
Have you got all the mods to your cat done yet?
