This is a small lift table that I had plans for. It is not as stable as I had hoped. You can get a small amount of compression when you press down on it. I have not measured it yet but I can see it move. In a lot of cases that will not matter but if you are trying to drill a hole to a certain depth, well it is going to be off by some amount.
I have not made a sacrificial top for it yet but that will not be a big deal to do. My intention is using this only on smaller parts that don't require a fence or other location fixed points. The part could most likely be clamped to the top if needed but the intent is more for light weight use in wood and plastic and not metal.
It is designed to fit my drill press table using dogs for location and holding it in place.
You simply turn the knob to go up and down. The lift goes from 2.2" to 10" but as I have it mounted it will set higher and again I have not measured that distance.
And yes it can be located at 90 degree locations using the dogs. If you want a different rotation then some external clamping is required.
This has been on the back burner for a while due to the flex but perhaps someone will have an interesting idea how to fix that????
In the mean time I'm now working on making this usable with my SO to make a co-planer tape board to work piece.
