Denis Goyette Posted April 13, 2003 Posted April 13, 2003 Just about to go 3D, so I tried to see if the hull bottom fit onto the keel and..... No It doesnt . :x The hull bottom measurement by the plan should be 157" I got that... The top of the keel calls for 154" and 3/8' ...I got that also. I did the 1" 3/4 notch in the keel stem. I tried it and still, the hull bottom doesnt sit on the keel :? Do I have to force the hull bottom on to the keel or should it sit on it's own ?I just dont want to force it and damage something. I am a little confused. Is there anyone that ran into the same situation? Thanks Denis Quote
Denis Goyette Posted April 13, 2003 Author Posted April 13, 2003 My keel is already laminated . So I thought i could either trim the hull bottom bow a bit or make the notch in the keel a bit longer but i dont want to change the angle of the forward bulkead from hull bottom to the deck......(does that make sense? ) Denis Quote
Barry Pyeatt Posted April 13, 2003 Posted April 13, 2003 Denis, When you lay the bottom down onto the keel it typically won't conform to the curve well until it is screwed into place. If your dimensions are as stated then it should pull down into place just fine. If you do need to make the slot in the keel a little deeper then just do it. You can fill the remaining space with epoxy after it is assembled and it will both seal the cut wood and help secure things. If you begin secrewing the bottom down at the stern and work your way forward, your relationship with the bullkheads will remain constant and you shouldn't have any problem maintaining the mastbox angle at the forward bulkhead. That angle is one of the more important angles in the assembly procedure but all of the others are going to be adjusted a little with assembly anyway. None of them are exact as most of them are faired into one surface or another as you go. Just try to make certain your keel is centered, and straight as you assemble it to the bottom. That is pretty easy to accomplish as you move forward, just check it against two reference lines drawn on the underside of the bottom as you screw it down. As has been stated many times before...you are building a boat, not a piecee of fine furniture. But it is really good that you are asking lots of questions. The only bad question is the one that you don't ask that results in having to take it apart and do it over. :roll: Quote
Denis Goyette Posted April 13, 2003 Author Posted April 13, 2003 Thank you Barry I'll just give it a try and hope for the best Denis Quote
capt jake Posted April 15, 2003 Posted April 15, 2003 Denis, what Barry is saying makes sense to me, though my hull was assabled when I got the boat. Derek, you just did this, do you have any advice here??? Quote
Derek Posted April 15, 2003 Posted April 15, 2003 I found that a tad bit of trimming was required with mine. I assumed it was due to slight fluxuations in the loft of the keel. I simply used a chisel to whittle a little more material from the slot in the stem and shaved a hair off the foreward end of the bottom hull. Most of this was to get the distance required between the aft keel and aft hull bottom as I used a 1/2" transom instead of 3/8". Quote

The top of the keel calls for 154" and 3/8' ...I got that also. <snip> [/quote'] You may want to double check that 157". The drawing on page 6 the text between station 9 and 10 says "Overall bottom length 12' 11 3/4" (155 3/4")". The error comes from the 1 1/4 " measurement at the bottom left of the drawing. If you look closley, you'll see it measures from the aft edge back toward the front. It's a subtraction, not an addition. Here's how I add it up - station 0-13 is 13' or 156" Minus 2 1/2" at the bow, plus 2 1/4" at the stern=155 3/4". If you ADD 1 1/4 = 157. See how it happened? The dimension lines at the lower right of the drawing are drawn incorrectly. It's easy to misread that the 2 1/4 measurement goes between the wrong lines. I almost made the same mistake so I know how you did it. Quote
Denis Goyette Posted April 17, 2003 Author Posted April 17, 2003 Please John take a look at the pic and tell me if I understood right Thank you Denis [attachment over 4 years old deleted by admin] Quote
MikeStevenson Posted April 17, 2003 Posted April 17, 2003 Hi, Denis is correct: the line for the corner points (where the sides and transom meet) is one inch aft of station 13. Mike Quote
John Teetsel Posted April 17, 2003 Posted April 17, 2003 It doesn't get any more authoritative than that. Quote
