Scissors Lift Table

 I have wanted an adjustable table in my shop for years and  then Steve DeVries brought one to our guild meeting in May and I watched a video ( many, many times) of one being built by Marius Hornberger and I followed his design with a few personal twists of my own.
 
 This lift is built almost entirely with high quality maple plywood and the nut block is some hardwood from my wood room and I can't identify it…but it is hard to bore and thread. It just yelled pick me , pick me when I went looking for a piece for that block!!
 
 I did a blog ( https://www.lumberjocks.com/Slovenian/blog/133657) on it earlier  to show the way I went about it.. The lift has 1 1/2" thick by 2 1/2" wide arms and 1 1/2"x 3" top and bottom frame members. All the bushings in the scissors and connecting block are DOM steel tubing and the pins are 1/2" steel. The threaded shaft that runs it up and down is a 3/4"-6 Acme thread and the casters are 4" 2-way locking type. The height range is from 17" to 57" and it takes 107 turns for the full 40" travel. I  made  a 1" 6 point socket driver for it to use on a drill.
The bearings are 1 3/4" OD and 3/4" ID and fit over the 3/4" bushing sticking our of the scissors arms. In front of the nut that crank goes on is a 1 1/4" roller thrust bearing with a 1 3/4" bearing pressed into the inside of the top front frame member and it supports the shaft in the front. I have Delrin block in the top back member that supports the back end.
 
This was design as you go project with a lot of visits back to Marius' video.
 
All the wood is finished with Boiled linseed oil and may get some poly on it later. The top is a small laminate covered worksurface that had to be cut down to leave 1 1/2" overhang all the way around for clamping.
 
It is going to work tonight in the barn…...........................Cheers, Jim

That's really cool, looks handy :)
Nice, Jim! Does it get a little tippy when it’s all the way up, or is that an optical delusion?

May you have the day you deserve!

Nice! I think I remember seeing this one.

Wow that would stretch the synopsis or fire them up. A terrific challenge and looks like you passed with distinction.....

Kerry - Working with wood, the smell the feel, is such a joy, its a meditation of sorts.

NICE !!! Should be very useful. Great job.
Thank you all for the nice comments. I wish I had one here in Arizona.
Hi Dave. it does get tippy when way up. It is okay if you put the load right over the scissors instead of out on the end. I normally use it from 20" to 38".

Hi Steve and Pottzy..good memory!! . It went on Lumberjocks just before they ruined the site and I wanted it here for reference. I'm bringing over all of my good ones eventually.
