Picture of Hand Crank TV Lift

TVs are great and all, but when they're not in use I prefer that they'd not be seen. They're big visual voids that don't exactly bring the room together. There are two options for this: covering them up or moving them away. Also, I'm using plenty of electricity as it is so I decided to go for a hand crank TV lift.

The operation is simple. Just insert the crank and turn it to get the TV up or down. The whole action takes less than 30 seconds. And it's fun to insert some kind of old-time action of moving things around to a high-tech device.

Step 1: What you need

  • sheet of 3/4" plywood
  • scrap wood
  • wood screws
  • conduit brackets
  • RV scissor jack
  • 32" HDTV
  • table saw
  • cordless drill
  • socket wrench

Step 2: Measure everything!

The two things we need to know all about are the TV with its stand and the scissor jack. First of all, I looked around for the scissors jack with the most vertical travel. This ended up being a heavy duty scissor jack that's meant for raising RVs and it has 19" of vertical travel.

With that information I knew that the biggest TV I could use was a 32" model.

OK, now with the items selected, it's time for lots of measuring! The platform for the TV needs to have a nice margin around the stand so it doesn't fall off so be sure to measure the footprint.

After that, measure the scissor jack in both its collapsed and extended positions. The threaded rod extends far out to one side when it's all the way up.

With this info, it's now possible to determine the minimum interior dimensions of the cabinet. That turned out to be 40" x 13" x 26"

Step 3: Cut the pieces

By factoring in the thickness of the plywood this left me with these cut pieces to cut on a table saw
  1. 2 pieces at 30" x 13.75" (sides)
  2. 40" x 13" (front)
  3. 41.5" x 30" (base)
  4. 15" x 12" (top left)
  5. 15" x 30" (top right)
  6. 26.75" x 40" (back)
  7. 12" x 24" (platform)

interesting project, and by the commnents below, interesting how so many people seem to prefer a motorized version

I can't tell what tool you're referring to - he mentions drills and routers but nothing specifically or by name.

Personally I'd hang the monitor on the wall on a proper bracket and be done with it, but to each their own.

I counted five gratuitous appearances of Sear's Craftsman brand, including in the video at 00:31 a specific verbal mention of the Craftsman Bolt On(TM) system. The stand-alone use of the Craftsman logo at the beginning and end of the video makes it have the feel of a commercial.

Here is my suggestion:
If a contributor is being compensated to hype a product, there should be some acknowledgement - perhaps the word "Advertisement" in the top of the video and picture of the drill.

My apologies - you are correct. I generally don't bother with the videos because they add little to the step-by-step flow.

For me video only helps with the "how does it actually work" rather than "how is it put together"
We have a be nice comment policy.
Please be positive and constructive

Learning11 year ago all you'd need is a converter to convert the power source! Nice build!
Thanks for the link.
Its the same jack that NitroRustlerDriver displayed.
Pick up one of these guys and you won't need to raise it by hand.
That's great! But where do you buy one and how much does it cost compared to this man's idea.

Nice gadget.
If you're going to motorize it, I'd recommend keeping it simple.
Since you've already made the hand crank lift, just use your cordless drill to turn the crank, if you ever get tired of hand cranking it.
Oh, one question.
Did you have any trouble with the tv tilting left or right and not staying straight?
I guess it might move while cranking it up, but will stay straight when it's not being cranked?

HA! I love the notion of putting forth a bit of labor before you can be lazy. More human power!

Two things. First, put a motor on it. mechanical takes very little power, there's not a lot of point in worrying about it for something used a few times a day like this. Heat or cooling is where it's effective to conserve, or maybe a large continuous motor. This would be maybe a dime or two a month, maybe per year even.

Second, the large screw/nut system is used to take the load of a car. Since it's unlikely people doing this will use it as a jack again, you might consider using a dremel to cut this screw out, and putting a 1/4-20 or 8mm threaded rod and coupler nut in its place. Then it would be very easy to use a NEMA 23 or 17 or similar DC motor to run it, and have extra leverage to work with a smaller motor.

I too love this idea but with everyone else's comments I think that there are things missing and could use some more work on it like having hinges that allow the too to swing to the back when opened and then use drawer slide inside to guides to the lifting parts and keep your tv sturdier

Electric motor but good idea

Do you have plans for the box? Maybe trim it up to turn it into a piece of furniture?
i really like this.

I've had a similar idea for a while but have lacked the motivation to do it.
If I ever get around to building it, I'll make an instructable but it won't be anytime soon. :)
Very nice Idea I love it
but why not drive the crank by small motor like car window motor?
i think harbor frieght might sell 1 a bit cheeper tho.

very smart idea.
