  1. Laminating sheets of plywood together

    Konrad, In answer to your question, how to scarf a full sheet of ply, I think Phil Gowans has the best answer on his site: http://www.pragdata.com/philboat/ConScarf.html However, that requires a lot of trust in your eye to get it just right. I used a "lap joint", where I basically used my router to trim half the thickness of the plywood from both sheets. Alignment was tricky, but it worked out quite well once aligned. I logged my notes on my site: http://www.phil-davis.com/boat Click on: Construction Log -> 05/12/2002 Hope this helps
  2. I had a sad day

    What???? Jake has a sail boat????
  3. Hull Speed & Book Review

    Wow, what a book "The Annapolis Book of Seamanship" by John Rousmaniere (Click Here for the review of the book on messing-about.com.) My loving wife and daughter found this one at the library and for some unknown reason thought of me :roll: I guess they LOVE me! :oops: I have been reading this and found, for the first time, an explenation that makes sense about the hull speed. It is basically a physical property based on the wavelength created by the bow wave. It also points out how to calculate your speed based on the number of waves along the side of your boat. For example, if you have three waves from bow to stern, you are going 1/3 hull speed, 2 waves is 1/2 hull speed, 1 wave is hull speed. The reason you can't go faster is due to the fact that you can't break through the wave. Planing boats get up and over it, so they can go faster, but the displacement boats cannot. Since (bow) waves move at a fairly consistant rate, the boat has a limit based on the LWL. But, as we have discussed before, some boats are more apt to hit that limit than others, and some will hit it more quickly, while others can plane and go even faster. So, the "Theoretical hull speed", in knots, is determined by multiplying the square root of the LWL by 1.34
  4. fiberglass problems please help

    I think everyone else has supplied sufficient answer to your request... I want to know about your last statement of the first post: This sounds like a late night stelthy excursion... lets have some more details! Please!
  5. Dumpster diving, my lucky day

    Nice Find! $376 is a good price too.... I think mine will be a tad over that! (like an order of 10)
  6. Choice of boom connection

    You can pretty much do the same (spillage wise) by droping the gaff. Has anyone given any thought to a boom-less rig? Just the next logical step after a loose-footed sail.
  7. Choice of boom connection

    I like the boom jaw idea too. I believe this is a picture of such a deal... with a small platform to hold it up when the sail is lowered. Adding a boom vang and/or a down haul would probably be a good idea, unless you added a platform above the jaws to keep it from rising up to far. That would give it a channel in which to move around. You would need to give it enough play to be able to raise up some or something will give way.... usually causing breakage (and always the part that is most difficult to repair) Barry, why do you make your daughter wear a bit? And what's with the horse on the transom? You might want to seek professional help!
  8. Sanding jig

    Joel, I like your jig. On the front of my belt sander is a slot for attachments. I tried to attach a wooden straight edge to it, and ended up putting two additional screws in it to keep the angle locked.. but it wouldn't work right. So I abandended the idea and have been doing mine by hand using the straight edge to check the angle. I am not sure why, but my angle was quite a bit off when I started. I have gotten down to about 1 degree, which I can live with. But it takes a while. I have completed both sides, top and bottom, from the front bulkhead forward. Time invested so far is about 4 hours. At this rate, I figure 12 more hours to finish the outer stringers. I might have to revisit the jig idea again!
  9. Adding ballast, early on

    How about using the new packing material.... the stuff they inflate. That stuff seems pretty good about retaining the air.
  10. varnish over paint ?

    Yeah, wanna come paint my boat? I don't quite see your ridges that you are talking about, but I don't think an extra layer of varnish will hurt anything.
  11. Home improvement update OT

    Yes Jake, Your bamboo dloor is quite lovely! I have never seen a string like that, but I would listen to Barry... he is VERY smart and knows everything!
  12. [OT] Hurricane Isabelle, in our area.

    Yet another insurance industry that is corrupt! Oyster... have the birds come back yet? When did they return?
  13. Hurricane Juan - Looks like we got our own . . .

    Wow, I didn't even see that one coming! I hope everone faired OK up there!
  14. [OT] Hurricane Isabelle, in our area.

    She was quite a storm! I wish you well while you dig out! I have to say that I am quite glad that she slowed down before hitting land. It could have been much worse!
  15. Glassing the keel?

    You can also get Kevlar from http://www.raka.com Click on Woven Fibergalss Material... about half way down. They don't have as much of a selection as the other site, but you may find something there that you like, often cheaper
