I needed help supporting my maple lumber when ripping it on the table saw. These were unsurfaced 8/4 boards (2″ thick), 9 to 12″ wide, and ten or eleven feet long. To rip these by myself, I needed something like this to support the board coming into the saw, and on the outfeed side. The outfeed side in my case for a board this long actually has to go out my open shop door, and down a step, so it needs to adjust to fit the saw height when sitting down a step. I needed something that would fold up for easier storage.
