With the frames complete, it is time for the longitudinal members, the stringers and the chine logs. First some raw sawn timber needs to be had from the local sawmill:
Then the raw timber needs to be selected, cleaned up and cut in neat long strips of proper sizes. I need 3 kinds: stringers ~3.0x2.4 mm, chine logs: 5.0x2.4mm and the chine logs that bind the hull to the deck: 7.0x2.4mm. All of that needs to be knot free and straight(-ish) grained.
I did not manage to find a single nice board that would be long enough (~5.5m) so I will need to join them. A 10:1 ratio scarf-joint will do here. I started cutting the first scarfs by hand using my power plane. It worked, sort of, but required a lot of doing since the power tools are too big and heavy for the small diameters of the parts, so I had to fine tune the faces with a hand plane and chisel. A pleasure on it's own, but I could do better.
A simple scarfing jig came into existence. With the circle saw I have I can cut up to ~5cm depth (that already includes the ~1cm of the guide plate thickness) which is plenty for most scarfs I need. The 7cm ones I cut partially with the jig, then finished off with a pull saw and a hand plane.
It got a bit messy again for a second in the workshop:
I'll be installing in the stringers first, so I glued them up first (a matter of room, don't have it to glue everything in one go :) ). Since they are small and thin, I've set up everything together and will glue/clamp the lot in a happy little bundle:
The usual gluing strategy was used: pre-wet the mating surfaces with unthickened epoxy, then goop up some slightly thickened one, clamp (not too hard) and wait. Een kind kan de was doen.
cheers!
