Timely advice saves fingers (maybe)

Beyond being ingeniously executed, my table saw plans may have lacked a little bit of practicality. The table itself was a little undersized. And a little light. And TERRIFYING to use. And the battens are only 12 ft long. So I needed a better method to cut the 16 ft chine and sheer I had left to do. The method suggested by a commenter was exactly what I was doing before, but it made me rethink how I was doing it. I realized that I could cut off either side of the wood. That allowed me to set up the guide on the other side of the saw so I could finish the rip. Putting the workpiece on sawhorses also makes life easier. Why didn't I think of that earlier! Cutting these last pieces was much easier than this weekend's adventures.
This is my straight edge clamped to the work piece and some scrap support 2X6's. For this last cut the straight edge was actually off the work piece due to the warp of the wood. To keep it all together and hold it stable I put a drywall screw into the edge of the work piece. Drywall screws are the most versatile faster ever made. If I wasn't sure they would rust after about 5 min of water contact I would have used them for this project.
This is a detail of the straight edge setup. I measured the distance between the edge of the saw blade and the edge of the foot of the saw. I had to think about which side of the blade I should be measuring to for about 5 min to make sure I got it right. Then you add this offset to the width of the piece you need. Set the straight edge up with a few clamps and you are in business. I cut about 3 inches into the piece then checked to make sure my width was right.
This is my workspace right now. The next step is clean up. Then I will align the frames and start bending the chines and sheer into place. I didn't realize how much bend these pieces will have until now. Wait, I still don't have a keel! AHHHHHHH! So the next step would be to make the keel. And brace the frames and transom in place so I can bend the chines and sheers around them. I feel like I've been here before...

  1. Try here for steaming. You only need to steam the end that bends. Attach that end first, and the long lever of the other end acts to your advantage.

  2. Sorry for the split comments, make up a few block & tackles with cheap pulleys and some 5mm cord. This makes life so much easier than for bending things. Add a long clamp and you can get some twist in.
