The reason for this project was I wanted to have a large 4ft x 8ft table for my home workshop which I could lift up and drive my Jeep Wrangler under the table when not using it and/or to save space in the shop at night.
Complete Plans can be viewed on GrabCAD
In addition, I wanted the tabletop easy to remove so that the remaining ‘Metal Frame’ would become a Gantry Hoist Unit whereby I would hang a 1 Ton Chain Hoist for lifting heavy equipment items like lathes or milling machines onto their stands … and/or lifting the engine out of the Jeep for repairs, etc.
While I like the blue color in these renderings, my main reason for using blue is because part features show up well in the renderings … Yellow is another color that shows details & contours well in CAD rendered images.
Once the concept design was finished, I refined the design in SolidWorks to find out how much metal I needed and how much it would weigh. In addition, used SolidWorks Simulation to find the stress points and lifting weight limits.

The RED paint markings on the Gantry Side Posts are there to remind me that if I can see the red marks the gantry is high enough that one of the garage doors could hit it if opened … Much of the workshop area is completely clear, but on the odd chance the table is wheeled close to the garage doors hopefully the red markings will remind me to lower the gantry or move the table away from the door ~ I will let you know how that goes *LOL* 🙂
I purchased the Metal and started the project … Yay!! 🙂
Put a new blade on the Metal Cutting Band-Saw ~ For an inexpensive small metal band saw it works quite well, and with the new blade it was cutting extra straight … When I checked the cuts with my machinist square the 90 degree angles were as perfect 90 as I have ever seen from any band saw I have used.
The metal comes is 20 foot lengths and the photo below shows what was left over after cutting everything for the Lift-table project ~ SolidWorks CAD Software is very helpful for designing projects with very little waste … Even on small Home Workshop projects like this one. 🙂
After Cutting all the parts, the next phase was marking out where to drill holes …
I wanted this Lift-Table to be very adjustable which meant lots of holes …
After 364 holes I stopped counting … Very Adjustable … Lots of holes drilled …
Once the holes were drilled it was time to weld all the parts together …
I mostly used the Miller ‘inverter type’ Multimatic 200 MIG (Wirefeed) welding machine on this project, and I am still amazed every time I use these Miller ‘inverter‘ welding machines! They are about the size of carry-on luggage and weigh less than 40 pounds; yet, they weld better than machines that I had in the past that weighed a 1000+ pounds — AND the best part is they work off 120v or 230v power. (Auto-Sensing the Voltage) ~ Brilliant Technology!!
Also used the Miller Dynasty DX AC/DC TIG Welder on some parts …
Built a Welding table this Spring that fits over the top of the metal band-saw ~ The Welding Table and custom clamps worked quite will for this project.

Thanks to great CAD Software, a straight cutting band saw, and quality welding machines …
Everything fit as it should and I painted the metal frame flat-black.
To help know when the table is high enough to drive the Jeep’s hood under, I painted the inner lower legs blue and when I see the blue I know the bottom of the tabletop will clear the hood of the Jeep Wrangler. (If you look closely in the photo above you can see the blue paint starting to show)
The tabletop can go another 12″ above than what I need to clear the Jeep for larger vehicles.
In the future I am going to post a story about this little lift table that I made a few years ago. I use it constantly during projects and used it to lift the tabletop from my old table onto this new ‘Adjustable Height’ Lift-Table …
The small lift-table is raised and lowered by turning a threaded rod with a hex nut on the end of it that fits into a socket that is turned with a 1/2 horse drill … Simple/Stupid, but it works great!! 🙂
Once the tabletop was installed, I raised the gantry to a higher position …
… AND THAT’S IT … ALL DONE 🙂
— CHEERS …
UPDATE NOTE ~ Added an HOIST EXTENSION ARM to Table!!
UPDATE NOTE ~ Samu Suojanen from Finland sent me a nice note today thanking me for my ‘Lift-table’ CAD file design that I posted on GrabCAD. He used it in his robotic movement computer simulation project 🙂
