Sorry for the interruption – I’m on a timed system at the hotel.

Back to the spring joint. The spring joint makes for an almost invisible glue joint. I’m sure someone else can explain why this joint works so well, but I can tell you it works. I’ve made plenty of panels without spring joints and I have spent countless hours trying to clean them up. I’ve got an invisible joint on this board and spent about five minutes cleaning up the board as a whole.

After gluing we worked on completing the flattening process. Takes no time at all when you use a good jointer plane. But if you don’t have a jointer you can still do it, you just need to make the planes you have work. I took the opportunity to use a jointer plane (a Lie Nielson No. 7) and was amazed how simple it was. The length of the plane gives you a lot of bearing surface which allows the plane to ride over the board hitting and cleaning off the high spots. A shorter plane will not ride as well and can actually dip into the low spots making them worse than when you start. So while you can flatten a board with a No. 5, it’s not as easy. So if you can afford to get a jointer plane – do it!

We have a few boards in the class that had twist. That’s where two opposite corners are higher than the other two corners. You correct this by planing diagonally across the two high corners. Take a couple of light passes on the high side, then take a pass on the two low corners. You should see a light “x” across the board – this will help you see where the most planing needs to take place. As you plane, check your progress often by running the edge of the plane across the board—if you tilt the plane a little so that a shadow is formed that really helps to see the high/low spots. (The light showing through shows the low spots.)

Once you feel the board is flat start the smoothing process with a smoothing plane. I used the No. 4 and was really pleased with the outcome. Be sure to use overlapping passes, like mowing the yard. The over lapping will even out the smoothing process and alleviate the tracks. Deneb does not usually camber his blades to avoid tracks. He takes lighter passes so the camber is not necessary. This goes against conventional thought – but it works.

We moved on after the flattening and smoothing to laying out our tenons for the bread board ends. We sped this process up by cutting the main tenon on the shaper. The design of this board uses “haunched tenons.” I’ve not done one of these before and it’s a bit intimidating until you have someone explain it to you. I’m going to have to go through my notes to make sense of this, but its cool. I promise you that I’ll get to this when I get home.

Rats—- going to time out on my connection. Will finish up in another entry.

-- Like a bad penny, I keep coming back!
