remember that in working with wood it is often possible to fill, patch, and
fake a great finish. While a perfect fit would be nice many (most?) of us are not able to accomplish that (and with some of the new glues the perfect fit is not desirable) save your sawdust--mix with epoxy and fill as needed. seams that are glassed can take a lot of less than perfect fit and seams that have a fillet . . . . now Mr. Sawdust in his book on setting up the Dewalt RAS talks about getting tolerances of 1/128th of an inch. That is lost on me as I have trouble seeing a 32nd on the rule and a 64th I just can't even see. give yourself a break and enjoy tolerances that a real person can sometimes do. Brian |

Brian Brian: I appreciate that perspective because I have been wondering about the correct philosophy of wooden boatbuilding. Although I strive for accuracy, it is unattainable for a person of little woodworking skills like me. So, do I remake parts that dont quite fit or do I make them fit and then "make do" by covering with epoxy putty in the end? Being somewhat pressed for time and being impatient, I know I will simply "make do". However, one of my intentions with this project was to determine if I had what it takes to possibly make a larger boat later. Last night, I attached the aft bulkheads to the cockpit sides. Although I thought I had measured the cockpit sides correctly at 10.5 inches, mine came out at 10.25" and it looks as if they should be maybe 10.75" high. I guess I will make some sort of shim. |

Being somewhat pressed for time and being impatient, I know I will simply "make do". However, one of my intentions with this project was to determine if I had what it takes to possibly make a larger boat later. when making my first boat, the plywood Dogskiff on my website, I bent the plywood around the central frame and held the ends in place with string and tape while I measured for the transom and took the framing angles with a carpenter's bevel. The pieces were then cut to the exact angle. It may be a cheap boat but I couldn't get a fingernail between the plywood and a frame at any point. Close fits and bedding (putting some kind of goo between the wooden pieces) can make a boat last much longer. People have criticised my practice of using low cost materials but the boats are still in regular use. -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-freenet email must have "notspam" in subject or it's returned |

... I used the 1" #8 screws instead of the 3/4" ones because I wanted more holding power. They did go all the way through the stringers. They arent a work of art, but I think they are ok. I wouldn't do this on the hull below the waterline. Screws should only go 3/4 of the way into the last piece. When in doubt put them closer together. However if you are using screws and glue the screws are not that important. They clamp the pieces togehter until the glue sets. I've removed the screws and had the glue hold fine. BTW when I have used oversize screws in a pinch I've ground down the protruding points with a grinding wheel on an electric drill. Its too easy to grab hold of a boat somewhere and scratch a finger or palm on one of those points. -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-freenet email must have "notspam" in subject or it's returned |

Tonight, got one centerboard box made, ran out of material (3" wide material) for second. Decided not to enclose it before sealing and painting it. Strange that the instructions do not specify painting the inside before enclosing it. On the one daggerboard trunk that I've made I gave the inside surfaces two coats of polyester resin for abraision resistance, just the inside exposed surface, leaving the gluing surfaces uncoated. To help the polyester adhere to the plywood the first coat was put on uncatalysed and allowed to soak in over night before the second catalysed coat was put on. Then the inside surfaces were given two coats of polyurethane liquid plastic for extra waterproofing. This was a winter project so had the luxury of lots of time to allow things to cure. It was also a lower cost alternative to coating the inside with epoxy resin. I reserved the more expensive epoxy to gluing the daggerboard to the boat and sealing the slot with a couple additional coats. -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-freenet email must have "notspam" in subject or it's returned |
