‘Over Jeep’ Workshop Lift-Table

Up_and_Down_View

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

Metal Frame can be a Gantry Hoist to Lift Heay Items Onto the Welding Table

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!! 🙂

Raw Uncut Metal Waiting to Become My New Lift-Table

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 …

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.

Little Lift-Table is Very Helpful in the Workshop

Little Lift-Table is Very Helpful in the Workshop

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!! 🙂

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 🙂

SolidWorks CAD software has a ‘Decals’ feature which allows users to take a graphic image and place it onto parts, whereby it will automatically wrap around the contours of individual parts and/or assemblies.

Gift-Card Design Updates $

Gift Card Updates Amount with Every Purchase

Gift Card Updates Amount with Every Purchase

Designed this new type of Gift-Card about a year ago that uses micro digital ink to update the $ amount left on the card after each purchase.

I think it would be helpful to know what is on each of my gift-cards by just turning it around and looking at it while at home… Have lots of old Starbucks Cards, Target Cards, Walmart Cards, etc… and I never seem to know how much is left on them went I find them in my wallet or drawer.

It uses digital ink similar to what is used in Kindle Digital reading books only it takes very little power to change the digital ink text on the back of the card… In fact, the static charge of swiping the card through the reader at the checkout stand will power the changing of the card amount to match what the reader says will be taken off the card.   Therefore, the data $ amount is still stored on an online server protecting against fraud just like normal gift-cards function today.

–CHEERS …

3D-Printed R1 Crawler Chassis

R1 Side-View Rendering

A few weeks ago decided to work on an R1 Type Chassis as a Surprise for Jim.

R1 'Split Chassis' Micro R/C Rock Crawler Concept Design

R1 ‘Split Chassis’ Micro R/C Rock Crawler Concept Design

I knew Jim Frye had not been feeling well so decided to take on a Micro Crawler Chassis design of my own based on an R1 Style. Wanted to try out an idea I had for splitting the chassis into two parts to make it less expensive to 3D-Print.

Usually Jim comes up with the Crawler Chassis concept and I figure out a way to draw it into SolidWorks … For this concept, I decided to start it on my own on night and actually had no idea what it would look like when finished.

Stayed up all night designing the R1 Chassis … and this was ths final result …

A nice bonus was I only had to draw one side of the chassis because SolidWorks has a great time saving feature called ‘Mirror Part’ whereby I was able to create an additional mirror image part is under a minute. * NICE Software Feature!! *

Not sure if this is a Chassis that will be Production 3D-Printed and sold; however, I am certainly going to make a few to give to my friend’s kids as gifts.
