Scissors Lift Table

 I have wanted an adjustable table in my shop for years and got excited when I saw one of these on Facebook for $29.95. That was a scam of course, but 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
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 am going to make 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. 

Cheers, Jim

Design as you go is the best option at times, well done.

What Eric said. You gotta be flexible. This worked out well! 👌

The early bird gets the worm but its the second mouse that gets the cheese.

I need one of these.   I know you built this a while back, is it still as solid as it was, when you first made it?
That’s cool. Is it solid at all when extended out like that?

Ryan/// ~sigh~ I blew up another bowl. Moke told me "I made the inside bigger than the outside".

NICE !!!  I would have lost sleep trying to figure out the lift system. Excellent job !!!   Mike
thast real cool jim.

working with my hands is a joy,it gives me a sense of fulfillment,somthing so many seek and so few find.-SAM MALOOF.

Thank you all for the nice comments. It is about 3 months old now and still very solid. I have used it with almost all my equipment in the basement shop. Steve DeVries from  out guild sell complete plans for the one he built that has more range than mine because the arms are longer. He used his for installing upper kitchen cabinets.

Hi Swirt, with a big load on it, it has some sway  side to side except when it is all the way up with the arms almost vertical. Then it has a lot less sway!

Cheers, Jim
Thanks Dutchy. I love it!!
