Hi Garey, I have to say that just about all of the frames required careful attention, the plan is close but very little is just "falling into place."

First scratch build for me so maybe it gets easier.

Progress


Since the prop struts have been sorted out I have been able to move forward, built some boxes/surrounds for the stuffing tubes so when its time to perforate the hull for the tubes I have a pretty good idea of where they should go ( thanks Classicboats for this idea ).

Only today did I receive my order from balsawood.com, pretty odd experience, wont do that again ! ( almost two weeks ).

I went to a LHS and picked up some 1/8 sheets of SIG airplane balsa to cover most of the bottom then used some 1/8 thick strips for the diagonal work up front.

Transom is hard 1/16 airplane plywood substrate.

Put in some reinforcing plywood around the stuffing tube boxes and in the back where the rudder tubes will go.

Sealed the interior with Z-poxy 30 minute epoxy ( I use the 30 minute Finishing Resin when its time for glassing the outside of the hull ).

Looking very sharp Tim. You can never have too many clamps.

Dumas Kit N20 - One Really Exists


Tim & all who are currently building this model, I just had to tell you that I "lucked out" while down at the Monroe, WA Hobby Show last Saturday. I managed to purchase a "complete" and original Dumas N20 kit, along with the original Fittings N20C. One of the first things I did when I got home was to lay out the Dumas drawing on a large table and place all the pieces (everything had been taken out of the die cut sheets presumably for tracing them) on the drawing to find out what I was missing. Without having read the Build Instructions in any detail, I think I have got almost all (perhaps 98%) of the pieces. I'm going to try to get all these pieces traced along with the fittings and see if I can't make a couple of PDF files to make available here on our Forum. In the meantime, if there is something that you're not sure of or need a tracing of, let me know. I'll try to get it uploaded here asap (still working on the Arduino Tutorials at the moment). Also, according to a couple of handwritten pencil markings on the original box, this could be the 1953 Chris Craft 35' Sport Fisherman. There is no price tag attached to the kit box -it had long since popped off, but the fittings box says it was worth a whopping $6.00. There are no dates on anything that I can see, but Dumas at the time they sold the kit were at 790 S. Park Ave in Tucson, AZ. and they had a Zip code, so maybe someone who knows can figure out a date.

When I get the time I plan on building it as the Sport Cruiser model.

Cheers, Barry

Thats an AMAZING stroke of luck there Barry !
There certainly are a few parts that arent defined on the plan that I need templates for, not alot of time at this very moment ( gotta go to work ) but we can work on this for SURE.

Tim
