Rotating Carriage for Slicing Staves on the Band Saw

[@drferry]

You are to be congratulated for making this system as accurate as it can be given the limitations of the mechanical contrivances we are forced to use. The problem with all such systems is that there are too many variables that have to be dead on accurate to make this sort of thing work. compare this to cutting segments for a segmented ring. I have two high-end Incra sleds that supposedly were going to make cutting segments a one-shot affair, but no matter how carefully I adjusted the sled, I still had to cut several test rings and make micro adjustments to get a perfect ring that required no sanding of the two halves. But then, when I needed to change the segment length, the new ring, with the same number of segments was not perfect. In other words, the plane of accuracy was intersecting the plane of reality only at one segment length. This was the state of affairs until the development of the wedgie sled, which changed everything. Now all one needed was two fences whose sides were absolutely parallel and a plastic wedge you could purchase from Seg-Easy, and you made perfect rings every time, including rings with odd numbers that could not be sanded in to accuracy. Why does the wedgie sled work? Because it does not rely on all of the variables that have to go into making a regular sled, such as the track being absolutely straight and parallel to the blade, the runner i n the track being tight and accurately adjusted, the blade being exactly perpendicular to the table, every component of the angle adjustment being dead on at all settings, and so forth. This is possible to achieve, but only with great difficulty, which is why my two Incra sleds sit in another room gathering dust and the wedgie sled, which doesn't care at all about anything except the things I mentioned above (that is it is independent of all the inaccuracies of the other system). Now, so sorry, but this is the same problem with your design. You have taken great pains to make all the adjustments as accurate as possible, but they are still system dependent. If you could design the equivalent of a wedgie sled for staves, then you would have made a fundamental advance in woodworking. I post videos in which I make, among other things, stave bowls under the moniker of Anduril Designs. I presented in my first video, "Making a Stave Tulipwood Bowl," the math and theory behind compound miters and how to calculate the angles and the amount of wood one needs for a project. I also told about how I cut accurate compound mitered segments. This involves setting the miter angle and blade angles as accurately as I can on my Makita miter saw using a vernier angle gauge, and then cutting a test bowl out of scrap wood and taping the segments together to see if the fit is accurate. It never is on the first try, so I have to tweak one or both of the two settings and try again. My average is six test bowls to get the settings perfect. Since we are fortunate enough to have two miter saws for the four of us who use my shop, we agree ahead of time to leave this saw alone until we have all made as many bowls of that shape as we want (most recently it was 18 staves at a 40° slope from the horizontal). This admittedly is a klutzy way to do things, but it works and allows us to make excellent bowls without having to go through the agony of resetting the saw every time, even though it is somewhat limiting. Good luck with your invention; now make a wedgie sled for staves!

A longer version would be nice for cutting glue up sections for 3D cutting boards

I love the videos, I finally got an 18” bandsaw I will need a Accu-slice system soon. I have not made any videos for a while been working to buy tools, I will be back to you tube soon, Do you sponsor any channels? I would love the help. Keep up the great work. FBWW
