    Default KVM - Sit Stand Desktop Prototype

    KVM - Sit Stand Desktop

    My latest project. A prototype.
    Made from scraps and left over pieces from bundle project purchases and previous purchases.
    So it was all in the work shop just waiting for my use.

    The gorgeous lady was talking about a sit/stand desk top.
    I had a look and they are so expensive.
    Thought I'd have a go.

    Stumbled onto an instructable for a simple light weight notebook sit stand desk here:
    Convertible Standing/Sitting Desk for $200
    Make this look easy.

    So took the basic design and beefed it up for my iMac.
    Can't have it dropping.
    And wanted a stable work platform without flex or shaking.

    We have some very nice matching desks
    so changed the design to a sit stand desktop.

    50 x 50 Hard wood battens.
    They were silver grey.
    I tried to skin the grey off them a bit and straighten them with the table saw as I didn't have a thicknesses.
    The wood was so hard and the blade was so gummed up they kept sticking.
    36" for $1 each for a pack of 25.

    Glued, Screwed and pocket hole joined.
    Solid as.

    Drawer runners off eBay for $10 a pair.
    Wasn't working until I make a solid square instead of an open ended U shape to attach them to.
    One fast spray of WD40 and much better.
    the slow close mechanisms are tight so no latches needed to keep in place.
    Might be the quality of the slides but more than likely my inexperience as using them.

    The keyboard support had to be from 6mm as I didn't want it any higher than it already was.
    Which needed a bit of support on the very ends.
    Lucky the diagonal supports act as handles to lift the work area.
    Regrettably its so heavy I have to step around the back to lift the counter weight to lower the work area.
    No big deal.

    I've had another test I just need to apply more pressure properly on the diagonal support to get it to come down.
    Now that I'm thinking about this as I type it,
    I'm wondering if I removed one of the brick counter weights if it would be easier.
    Anyway a work in progress.
    Yes! That was it. Too easy.

    Even though I told the good lady it was just a prototype and I could paint it black,
    the lady doesn't like it at all.
    As it doesn't go with our nice matching office furniture.
    She says it looks like it should be in the work shed.
    I think I'll give it to her as a Chrissie Prezzie! LOL

    Surprising I had designed the lift for 13"
    Which is the top of the desk to my standing elbow.
    And it came out perfectly 13"

    Sounds like a good idea. How far along is yours? Do we have some pics to come?

    Looks good. Have you considered some kind of gas strut or piston to slow the drop in case of cord breaking?

    I like the concept

    Thanks for the interest.
    No.
    That cord is thick and strong.
    And the slides are hard to move and the slow close helps.
    I can install some latches on either side to keep the work area from dropping.
    I've also been thinking about something to lock the monitor base down to the work area.
    Thanks,

    Horizontal starting
    accross the Original bundled hard wood.
    Middle and verticle piece on the right: after a number of micro passes on the table saw with a gummed up blade.
    Bottom: single pass on a jointer

    Although the lady NOW says the original might be what some people want
    and that the middle has some interesting features.
    LOL
    I'll be building the next version from the jointer results.

    No thicknesser.
    So wondering if running all four sides thru the jointer would be good enough.

    I've been working with "the dark side" timbers for quite some time.
    This lighter timber I find quite attractive.

    You can dress all sides on a jointer. If you want relatively parallel this will be a challenge.

    It may mean dropping one side onto the exit table and then doing a pass to take more off one side to bring into parallel or tweaking with a hand plane.

    If you are not after actual perfection but simply for it to look good to the eye and slight differenced at joints can be made good with sanding

    All good mate. Never too late for a like and positive post.

    At the time I needed a project and have been wanting a standing desk for a while.
    The prices at the time for one off the shelf were ridiculous. $500+
    It all worked out well.

    I have to really force myself to actually use it and stand at it.
    But once I get used to standing again it's easy.
    It's much better using a standing mat as well.
    Thanks,
