Got all the frames mounted on the building box. In my mind I'd been expecting a few hours (meaning a couple of days) of adjustment to get them straight but blargh I have to admit some disappointment at how far out my supports were. As I was having difficulty eyeballing which frames were out I added a second string down the centreline. This makes things clear as day. Frame #1 is a joke, Frame #4 which should have been setup when I was getting the hang of things is significantly off centre too (and actually its off vertically too now I come to remeasure it). Despite it getting late I remounted #1. Didn't take long to get a much better attempt. Frame #4 will get remounted tomorrow. And then I'll continue adjusting the others to get everything straight enough for a dry fit of the girder. Won't be sniffing a stringer until the weekend for sure!!! Take away thoughts: Second string on centre line is awesome Needed to do a better job with the initial layo...
Spent the last few days fairing the chines and stringers to match the template. I was pretty nervous about this stage and I guess am still a little worried (and will be until the next worrying thing comes along) but overall it seems to have been quite straightforward. And I'm very impressed at how the Farr 3.7 design has everything setup, very nicely planned out! Basic approach when fairing is to plane down the top sides to match the curve template photographed in the previous post. In the end this is fairly easy because the notches in the laser cut frames are accurate enough that they guide you. Before I attach the first ply sheet I'll do a final check but I'm ready to cleanup and seal the stringers. Fun times making a nice little mess. Team #431 in action. Before sealing I filed/planed/sanded the bottom (top) side of the stringers. My thought here is the sealer will last longer with a smooth corner to attach over. Probably pointless and would have ...
After a bunch of phoning around we sourced our wood and a laser cutting service. Guillermo at Ikon Displays in Otay Mesa came back with both a good price on the job and an 8' x 4' machine that could easily handle the ply sheets. A couple of other places in SD came back with good hourly rates but had smaller machines that would require extra work. Otay Mesa is pretty far from our North County base in Oceanside but the best ply quote came from Forest Plywood who could deliver to their facility in National City and searching around we found that TH&H in MiraMesa had a good stock of Sitka Spruce and Western Red Cedar so we borrowed a truck and made a round trip of the three locations. All three of these companies have been excellent to work with. Ikon uses Illustrator to manage their cutting files and the autocad files didn't properly extract scale (there are old work arounds for this but the current state of software meant these have changed). Guillermo came up wi...
