I have a hand-held electric saw ( a Black and Decker ProLine P40 with a 7 1/4" ripping blade with a 1/8" kerf ). It easily cuts through 2" of cedar. My plan was to use it to rip a 2" deep cut down one side of the log, then reverse the log and rip again from the opposite side. Hopefully, the two cuts would meet and a nice clean slice would fall off ! I tried using the saw fence ( with a long strip of wood attached to it ) but it was difficult to hold the saw steady so this produced a very wobbly cut. So I tried another approach with a U-shaped jig. I cut a piece of MDF seven foot long and approx 12 " wide. I attached two uprights along this base ( approx 7" apart ) with rebates along their inside top into which my hand-held saw fitted snugly. The blade of the saw was 3/4" from the inside edge of one of the uprights. The log was placed in between the uprights, clamped in place with wedges and I ran the saw along the rebates in the MDF. Then I turned the log over and repeated the cut. This was not 100% successful. Although the
log faces were fairly smooth they were not
exactly parallel so the cuts did not meet perfectly.
However, as I was planning on cutting the
new pieces down the middle, this would
remove the slight step ! I then ripped
the pieces into strips on the table saw. |

This stash, I thought, would be enough timber for the kayak ( the book suggests around 1000' of 3/4" strips ), but in fact I needed a slight bit extra. Luckily I found some extra cedar being thrown out from a building site behind our offices so I ripped this up also and used it when completing the deck. I did not bead and cove the strips. I would have liked to, but I did not have a router. This did not turn out to be a problem, just some extra work planing the edges to get a good fit lengthwise, but an advantage is that you use slightly less strips. I scarfed the lengths together using a simple
scarf-jig to cut the scarfs and another jig
to hold the pieces when glueing. These
jigs were a worthwhile investment.
They made scarfing extremely easy and accurate. |

It was probably not worth the effort to rip the cedar logs using my limited tool set. Next time I would seriously consider having a saw-mill ripping them to managable-sized planks and then finish them off myself. All of the scarfs which I glued together on the jig turned out beautifully neat, practically invisible on the boat. While stripping, I glued some scarfs in situ ( being lazy ) and these turned out horrible. I had to chisel them out and glue in a new piece of timber. Next time, I won't take the lazy option !. As I don't have an electric plane,
I cut the strips slightly oversize with the
intention of running them through the table
saw again and trimming to final size with
a 48-tooth blade which leaves a very smooth
finish. This proved unnecessary as the strips
are all eventually planed/sanded on both
faces when finishing the hull and deck. I
should have cut them exactly to 3/4"
X 1/2". This would have saved
time in cutting/trimming and also would have
given me more strips and less sawdust ! |
