Thanks for all the replies. When I got home from church I played around and found a pretty decent and easy way to do it. I made a very complicated jig with painters tape a cut 16d mail and a pen set to about 1 1/8 ". Ran that down the long edge marking a line. Then followed that line with my circular saw. After that I took my router with a double fluted 1/4 bit and made the cut as I drew the router backwards toward me. I worked well because the circular saw kerf not only gave me a line to follow but the chips were able to escape allowing me to make the cut a lot faster then I thought I'd be able too. It's not cnc perfect but I think it may work. Now I've cleaned the strong back and am about to but up the molds/forms and hopefully start stiching. My helpers went swimming at my parents house

No stiching today I found a few mistakes I made cutting the molds so that slowed me down. I salvaged one, trashed one, and the other one just needed to be shortened. Got what I had leveled. Maybe tomorrow? Goodnight

Question on stringers/frames

Post by Jwhitakeriii » Mon Jul 30, 2018 9:29 pm

This may be a dumb question but I got everything square, level, and plumb but the stringers are sitting proud in frames b and c. I checked my measurements and they are correct but this does happen to be where there are curves in both the stringers and frames. My curves could maybe be over curvey on the stringer and undercurvey on the frames creating the proudness. Or maybe that's how it's designed?Do need to pull the stringers out and trim down until they are flush or build on and fill those spaces when I flip?
Thanks everyone for the help this far

I had the opposite problem during my FS18 build, my stringers set below the frames. I was told to shim to flush them up with the frames. I would suspect you would need to flush yours as well, in your case trim. Perhaps Jeff or another builder can confirm since you are building and LM18, but again, would think they need to be flush.

Check your stringer spacing to see if maybe inside face/outside face dimension is right.

The whole thing should be flush, nothing sticking out.
