Chinelogs
The epoxy on the chinelogs took well, the scarf is a success as far as I'm concerned. Once I sanded down the excess epoxy the joint looks clean and tight, I'm happy with the result. Today I placed the chinelogs in position onto the sides of the boat. I did things a little opposite because I'm by myself and I was trying to make the operation go smoothly and precisely. I placed the bow piece 5cm back as dictated by the plans, with 1cm overhang the bottom edge, and screwed it in place. I placed a total of 6 position screws that are not designed to provide the clamping power, I used clamps instead. I get the feeling that the plans call for screws to be pushed through from the outside of the hull, but I felt I'd have more control over the chinelogs if I did everything facing them. I was careful to place the screws in hidden locations, behind BH's, in watertight tanks, etc. I have pretty much 1cm throughout the length of the side, with a few locations with 1mm variations, of which I'm ok with. A pre-coat of epoxy, then thickened epoxy application, clamps, clean up (difficult), and viola:

Excellent progress! I've wondered about screwing the chine logs the way you did it. Glad to hear that worked. Did the screws go through the hull panels?
ReplyDeleteI used 1" drywall screws, so they did not go through the ply completely. I positioned two screws in the forward watertight bulkhead, one forward of the buttstrap, which will be visible, one behind BH3 and BH4 and one in the aft watertight compartment. I worked forward to aft using ruler and clamps and got a pretty consistent 10mm overlap throughout the sides.
ReplyDeleteSounds like you are planning to leave the screws in place? If so, that is more of a variation than I was thinking of... But, I like the idea and will give it some serious consideration. Thanks.
ReplyDeleteNo I'm sorry Bob, I am not leaving the screws in place. I tried to carefully "hide" them so the holes that are left when I pull them out won't be visible-- trying to keep the lines smooth and slick to the eye, per Storer's pleadings.
ReplyDeleteI am also building a GIS and am at te same phase right now. I did not see specific insttructions on screwing these parts, so I assumed that it was from the outside (painted side) into the chine logs.
