Hi there, I hope everyone had a great Christmas!

I guess it's time for another long overdue update on the TNT. :D

Finally got some 16' batters cut ( pop-quiz question: anybody care to guess how long it takes to find a 16' piece of pine at the big box store that's clean enough and straight enough to cut some batters from?..... :shock: ) and pushed enough stuff around in the shop to lay some plywood out this weekend and started lofting the hull out.

I'm glad that I'm doing it too. The 3D modeling that I did was really close, but not perfect, so I've been making the necessary adjustments to the data points as I go through the design and I'm really pleased with the results so far. It's amazing how lofting a hull full-size can show fairing errors that I still can't see on the Linesplan on a computer screen or on a sheet of paper....

Thanks again for letting me ramble....... :D
Dave

I'm glad to see you're finally cutting some lumber.

You really need to trek over to LL Johnson's, no problem finding clean, straight boards there.

Happy New Year!

Batters???..........really?!?!..........
I hate autocorrect...........

Hi Jim,

Yeah, it feels pretty darn good to finally start playing with the power tools and making some sawdust, even if it is just for the BATTENS so far....... :D

I've had a lot of fun going through the planning / design phase of this little project and it kinda strikes me how much the project has evolved in the process looking back through my thread, but I'm more than ready to start cutting and building at this point.

It should go together pretty quickly now that I feel comfortable that the design / construction wrinkles have been ironed out and I'm putting an order in for epoxy and fasteners this next week. Then it's a call to Johnson's to get the wood and plywood for the frames and longitudinals.....YAY!!!!

And never fear, that chunk of 18mm will be put to good use

Thanks Jim!! :D
Dave.

Hi everyone, time for another mini update....... :D

It's been downright frigid here in Michigan the last couple weeks, but that's been a good thing as it's given me some more time to work on the lofting and I'm finally happy with my "slightly revised" Jet TNT (I also realized that I oopsed and lofted the hull in reverse....... :oops: :lol: )

I tried to get some pics during the process, but the colored pencils that I used weren't very photogenic, so I ended up picking up some black 1/4" auto pinstripe tape to give the lofting more contrast for the pics. An added benefit was making sure that the offsets on the data points were consistent with the hull being planked with 6mm Okoume.

I think these latest pics gives an even better sense of scale for this little bugger. With the engine on its cradle, it's about 2" higher than installed height, but I think it should give a good idea.....

Looks good to me!

Hi Jim, hope you and your family are doing well.

I'm not positive, but I think the engine might have grown larger since I pulled it out? I don't remember it looking that size when it was sitting in the ski ..... or I may have contracted "toomuchisjustenoughitis" when I decided to build this thing?

I am pretty sure that it's not a case of bigger _____, more like less synapses firing when they're supposed to. :D

Oh well, too late to turn back now......

LOL!!

Hi Bill,

I don't know if Paul would be much help? I think he may be afflicted with the same disease? Maybe Paul and I can start up a support group for others who are similarly infected with this seemingly incurable condition. Now to come up with a name for the group that will give us a cool acronym! Hmmmmm........ :lol:

Thanks Bill,
Dave

Yeah, It's looking like it's probably going to be a bit of both doesn't it........

If nothing else Matt, it should make for some interesting sea trials when it's time to get it wet.. :lol:

I've been going through the past gatherings and I'm thinking that I'd definitely like to make it to G-12 this year so I'm hoping to see you and your Geronimo there, along with all the other great people and their great builds too, I'm shooting to at least have the hull done and painted this summer, depending on how far I get on it, I might even drag the TNT along . :D

Thanks Matt!

Jeez, and I thought I'd been gone a long time...How's that TNT coming?! :wink:
