Renovating an old wooden sports boat, am I mad?

I've prepped a bit of space in the workshop....
The plans I'm getting are 'full size', so no lofting required. But, I've thought of an easier way of doing this.... I have access to a large printer that will print directly on to vinyl. If I had PDF copies of the plans, I could print the frames on to clear vinyl, stick this to the timber, and cut around directly. Still using the template/router method, but a lot quicker than tracing. I'm pretty sure the supplier wouldn't let the plans loose in PDF format though, otherwise they'd be digitally traced and set up for CNC, an IP nightmare. So, I could scan the plans myself, but I only have an A4 scanner, not QUITE big enough.
Anyway, lots to be thinking about, looking forward to yet another winter project!
Are you going to build your frames from laminates? that way you can layout a jig on the MDF and use your full size plans to place the inner and outer clamp points. You could then use the frames for the strong back directly to create the moulds for the hull for strip & cold moulding or ply planking.The plans I'm getting are 'full size', so no lofting required.

Cutting them or steam bending them from solid wood does not provide as strong a frame for the hull.
Anyway good luck, you might be interested in this forum http://forum.woodenboat.com/

No need to use vinyl, just print onto paper, stick it on (lightly) and cut round thelines.It's exactly what I did when building a CMB from plans kindly sent by Thornycroft.

Fantastic! I built a balsa wood model of that very boat when I was about 10. It was about 3' long, the plans were in Meccano Magazine. The basic hull was for a racer called Brave Moppie then you could add a superstructure to various designs and I chose the Huntsman Brings back memories!

Checked out West Systems epoxy.
Checked out Cedar (thanks Mickrick!), which looks nice. BUT, there's SO much work to do in just making the frames and cold moulding, it'll be a long time before I have to think about planking/deck, so not a decision that would have to be made any time soon.
The plan is to make the frames from Douglas Fir. Cut out templates on thin MDF. Rough-cut the real frame on a bandsaw, then use a router (with a pattern bit) with the template to finish the frames off perfectly.

Which plans are you considering?

23' barrel-back 30s style runabout. 8 seats, inboard engine.Which plans are you considering?
They say mahogany and ply, but I'm thinking something more accessible in the UK for the frames (Douglas Fir?), and possibly cedar or mahogany for the planking and deck.
http://www.boatdesigns.com/Belle-Isle/products/724...
About to push the button on the plans tonight....
Looking for a local supplier of the timber too. It's all well and good having the best deal or the best supplier, but that's no good if they're the other end of the country. Luckily, I'm in the best part of the world for boaty bits so this shouldn't be a problem. Planning to price up the frames and stringers and bits over the next few days and get them on order, along with a bandsaw and pattern router bit. Might look at a router table too, that looks like a good, easy way of making frames from a pattern piece.
Looking forward to this now!

So, I should just cut out a bit of ply, stick a couple of barrels either side with some super-strong-sticky-glue and mount a V12 to the middle?
Whatever engine eventually goes in, it'll be a nice one for sure. I'm not going to spend 600 hours making a boat and then put a sewing machine motor in it.
RichB said:
Indeed, I was looking at this design last night and noticed it takes a V6/V8 engine. What are you intending to put in it?
Realistically, unless something magnificent comes up, it'll be a 350 or 377 MAG or similar. That's a 300 / 320 HP V8, 5.7 / 6.2L. Something like that, around 6L V8 300-ish ponies.Has to be petrol I think, no point saving money building one myself and then going for a noisy bus engine.

If the plans give you table of offsets lofting is easy. You only need to do half the frame, then flip it for the other half.Checked out West Systems epoxy.

Just lay the paper on your board, and trace it through by knocking the point of a nail through your lofting line.
Are you laminating the frames? If so you don´t need to cut the board, just screw blocks on to clamp your laminates to.
Use brown shiny parcel tape on your forms to stop epoxy sticking to them.

Get with the program....Current Cummins QSB 6.7 is 550hp and 1250 ft/lbs
650hp rating coming next year.
This should be amazing, engine wise go with a tried and tested marine engine, don't try and bodge a car engine in to it, unless there are specific ready made tried and tested kits to turn it into marine version.
