I recently acquired a used thickness planer. I want to design and build a planer sled for it so that I can get flat faces on boards. I have several question concerning the design of the various sleds I have seen.
The first question is how do the sleds deal with cupped boards. All of the designs I have seen have a straight support that fits under the board to be flattened. This does not really provide any support for cupped boards. Or are cupped boards not a problem?
I like the design by pmcustom but I am worried that the pressure of the rollers will cause the bolts to slip. One way I am thinking about is to use wedges, one on each side that can be adjusted by bolts through the sides. As the wedge is moved in or out it will raise or lower the support piece on that side. Good idea?
How close together should the supports be? I have a small “lunchbox” planer and the center table is only about six to eight inches long.
Thanks for your help ahead of time.
