Re: Tahoe 23 project, Norway

But how did he manage to dent the stringers in the first place? He didn't cover them with the floor? Good questions. Kids, water skis, anchors, fish guts, dropped tools :arrow: dents. With a little luck, a good boat gets used. :D :D :D :D I don't think he documented the floor. His website http://ww...

Re: Tahoe 23 project, Norway

Toivo, With respect to the motor stringers, we have been writing about strength and economy. Durability/abuse and rot is another important consideration. Mark Bonkalla built and documented his mahogany runabout build about 15 years ago. He used redwood stringers and uses his boat for waterskiing. A...

Re: Tahoe 23 project, Norway

Sorry, I have to step in here and say I believe laminating stringers to the plan dimension from a plywood sandwich is not a good idea for strength, especially for an inboard of the size you are building. Check your plans for the stringers, they specify wood (not plywood) for a reason. Plywood has a...

Re: Tahoe 23 project, Norway

A few things. First, the stingers are 16' long, with a minimum net dimension of 1 1/2"x 5 1/2". I agree with Dave, laminating is a good idea. A 2"x6" - 16' will tend to "wander". Straightening stringers with the form and frames and clamps is a pain. Lengths of plywood ...

Re: Tahoe 23 project, Norway

Scarfing the stringers would work great. A lot of people don't have the capability to resaw 6". I wouldn't be comfortable with doing a joint like you're showing though. It's more of an edge lamination than a scarf. Doing a scarf across the 6" width and 12-16" long (6:1 to 8:1 ratio) ...

Re: Tahoe 23 project, Norway

Ripping 6" wide is too wide (or tall if that make sense) for my table saw.
Is this type of scarf joint an alternative? And of course cut the joint so its longer than 6''

Re: Tahoe 23 project, Norway

Hi Toivo, I would do a lamination of both. Use the Spruce and laminate plywood on both sides of each. That would give you the best of both. It would increase strength and reduce warpage and the possibility of the Spruce splitting. Thanks, Dave Good idea. Can I still use butt joints? EDIT: And still...

Re: Tahoe 23 project, Norway

What would be the preferred way to make the stringers? I have the opportunity to use 2x6 spruce logs, and I think I can get them in 15' witch is what the pattern says. However, I'm a bit concerned that the log might warp over time. Should I use plywood instead? Laminate of 3/4'' plywood with butt jo...

Interesting. That's one of the things I'd like to change. The freeboard. If he active in this forum?

Re: Tahoe 23 project, Norway

I was wondering if maybe he had raised the deck?

Re: Tahoe 23 project, Norway

Looking at Edgar van Holtens build, I wonder how he managed to fit the motor in his boat under the lowered sundeck. Does anybody know?

Re: Tahoe 23 project, Norway

Are you talking about the subdeck, or the hull? The subdeck is attached with bronze ring shank nails. What most are doing, myself included, is to attach the hull ply layers using the Raptor plastic brads or staples. They hold the ply until the epoxy cures, and they don't have to be removed. You *co...

Re: Tahoe 23 project, Norway

Do I actually need the extra fastening on the plywood? Or ca i use small nails to hold it in place until the epoxy has harden?
