I am in the midst of putting a Lindsay Tornado back together. Until the conclusion of the Olympics, she will spend her life as with a classic main and jib, however I would very much like to put a spinnaker on immediately.
Now please excuse me if I get some language wrong here, as I am a recent convert to Tornados from I14s, 18' skiffs.
Looking at pictures, it looks like I need to add a second attachment point for the spin pole's shrouds, a fitting similar to the forestay bridles on the hulls, but placed closer to the bos. Do I need to cut the decks off and install some internal reinforcement due to added stress the hulls will take? Do I just epoxy the fitting in? Where can I get it? The boat has a nomex core, would that change anything?
Also, will the classic main be enough to support the spin? The class had alluminum masts until after Athens did they not? So it should be able to support the kite in the sky?
Additionally, we are still looking for some parts if anyone has used ones for sale. Specifically, most of our lines, blocks, spinnaker gear, and rudder headstocks.
Are there any guides out there for ideal sheet lengths?
Matt,
I suggest you post the same message on the TornadoCat list over at Yahoo groups: http:/
That is the best place around for Tornado information.
If you at the same time include information about where in the world you are there might be some parts around.
The bow fitting can be bought from Marstrøm: http://www.marstrom.com (call them, dont send e-mail!)
Or you can just drill an oversize hole, fill with thickened epoxy and re-drill. I think Hobiegary did something else which was elegant, but I dont remember just what.
The classic main will do, but you will need a lot of mast rake to balance the helm. Why not buy a used main from one of the pro teams. They lay off old sails all the time.

Dude, you're in my old stomping grounds!
Welcome to Tornado class!
My Dad, Geoff Dobbs, used to run SailCraft of Canada back in the '70's and
inherited
loads of parts left over at his farm in Arnprior from when the company went under in the early '90's. Post on the TornadoCat forum on Yahoo to reach him....he checks it fairly regularly.
To answer some of your questions...yes the Alu mast will be able to take the loads...but like all alu masts with a spinny, you've got to make sure never to release the main sheet in higher winds with the spinny up. Dropping the traveller is OK...but the mainsail is acting like a backstay supporting the top of the mast....kep her sheeted on fairly well and hold line with cleat.
For the bow tip stays, there are many solutions to consider. My current boat (a '95 Marstrom...Nomex core) is retrofitted for spinnaker. The bow tip is drilled through and a simple threaded deck eye is epoxyed in place. Mine is similar to this:
EyeBolt
But mine has a flange at the eye. The bolt passes completely through the tip and a washer/nut is installed on the inboard end. Grind off any protruding thread and you're done. While heavier than some solutions, it has been bullet proof for many years now.
Probably the lightest setup is to pass a plastic tube through the hole, epoxy in place, then pass a loop of 3mm Spectra through a good sized stainless washer, then the tube, leaving the loop knot & washer on the inboard side. Now just attached your pole end stays to the loops.
