Re: RB14 Strip planking

I looked at it an I can quickly draw some intermediate stations where the span between molds is quite large but not design a whole jig.

Re: RB14 Strip planking

That is a big job, about 4 hours of drafting.
I can't do it now, sorry.

Re: RB14 Strip planking

#1: strip planking I have built boats that way and know what is involved. All compound curvature surfaces will require spilling the planks. This is labor intensive. Fortunately, the majority of the hull surface of the RB14 is developable and in those areas, no spilling is required. I still don't see...

Re: RB14 Strip planking

Do you mean that you would cut your plywood in thin strips then glue them back together? Why? The design is already partial strip planking: to create the tumblehome, we cut one sheet of plywood in strips close to the transom but not the whole sheet. The other surfaces are developable and can be buil...

Re: New design: Tina

I designed her with a diesel 6 cylinder 200 to 240 HP depending on the marinization. The plans show a Toyota block available as Yanmar or Nanni diesel.
A Yanmar 4 turbo would work too or a Cummins, same engine beds.

Re: Foam for decks and framing on SC16

Yes, good advice. I don't think you will be able to save much more weight than what Capeman did.

Re: First Time Build - SK14

Start stitching from the stern, leave stitches loose (1") and progress towards the bow.
Tighten the bow and go back towards the transom tightening the stitches.
A 1/4 gap at the bow is fine.

Re: OB21 possible?

Good plan. Study the nesting drawing. I guess you will need 2 extra sheets of 6 mm (there is room for larger bottom panels) and one 10 mm for the extra frame. Maybe 2 extra 10 mm because of the longer stringers. I don't always get involved in the discussions on the forum especially when the other bu...
