This project is cool. It’s just cool. It’s also involved. Very involved. The results speak for themselves, however. Member TomBuilder at HomemadeTool.net built this pneumatic-powered scissor lift table right in his garage. He even dug out a section of the concrete and installed the table in the ground so it sat flush with the floor when not in use. Genius.
As you can see the build requires a fair bit of metalworking. Made mostly of angle iron and steel plating, the frame was constructed before any digging was done. The lift functions on pneumatic actuators and can be operated via a remote controller.
If it looks like a lot of work, that’s because it is; but if you have the time and skill it’s both a fun and functional project. You can get Tom’s full walkthough here, where he goes into VERY specific detail for each step, including his exact measurements.
