    Use two smaller pieces, and use the L-brackets on the beam through the middle, to hold them together (feel free to add extra joints using biscuits, overlapping thinner sheets, etc)

    See, for example, you can make out the joint where the two sheets meet in this photo: (Circled in red)

    I purchased and assembled a large table to fit a 1515 Lead machine. I like the table a lot, however it has one major shortcoming, at least for me. The caster plates are weak on this large table. I've already sent a support email regarding this issue, and I'm definitely NOT knocking the design. My shop floor isn't exactly what anyone could or would call smooth. It rough concrete, and since I have to roll my machine into and out of a work area, the caster plates have taken a beating. Has anyone else had this issue and what has been done to resolve it? Any help would be greatly appreciated!

    I can't find any info on how much weight these tables are designed to hold. I'd really like to know before I build (a 5x10 and a 5x5).

    What are you intending on placing on it, happy to let you know if we think it will be too much

    I really just need a couple of sturdy tables, I'll be using them for a lot of things rather than a single purpose. Maybe 200-300 pounds? Mobility is important. What would you think is the max weight for the 5x5 and 5x10 models, ballpark?

    It should be good to around 200-300 lbs yes

    Does anyone know the exact dimensions of the MDF on the1515 table top? Is it 68 inch by 68 inch? Just trying to plan ahead for the table build…

    Thanks

    After putting together a 1510 Table and putting a 1010 Enclosure on top of it (which is all great)...I'm left wanting some kind of drawers that would work well with this design. Mostly to store endmills and hold-down pieces. I've certainly found generic drawer designs, but hoping to find something that works with the aluminum extrusions of the table.

    I did notice that shelf idea, and looks very nice for a work surface/keyboard/laptop drawer. However, I was concerned about the load capability of the v-wheels being used horizontally to hold a drawer full of tooling. How could I determine how much weight that could accommodate?

    Suitably sized it should be fine. Endmills and holddowns surely weighs less than some of those old laptops people prefer for the shops :)
    Can always do a trial run and add more wheels later but we don't think it will be an issue.

    Otherwise you could redesign the concept to use the wheels vertically :)

    What is the recommended thickness of mdf for the 1010 table? Do you have the dimensions for the table top?

    I notice that none of the photos of the 1515 table show the bottom being used as a shelf, is there a problem with doing that?
    I was thinking of putting 3/4 Laminated MDF on the bottom to store some of my materials, would that be good as-is or should I add another support brace?

    The video shows it being used with a shelf at around 1:15

    It doesn't show if any extra support was used. I'm wondering if I should reinforce the shelf area?

    That's truly a function of how much load you intend to put on it and how much deflection you can accept. It is unlikely to fail, just merely flex. Besides, you will reach the load limit of the wheels (400 pounds total) before you max out the framing members. If you do feel the need to beef it up though, I would suggest another cross-framing member (dividing the lower bay into thirds) and screwing the MDF to the framing to increase overall rigidity of the table.

    Gotcha. I actually took my wheels off and have it sitting on feet. I like the idea of adding a 3rd brace.

    Is there a way to buy a 20601580mm rail to add under the table? I'm not sure if I'd have to just buy a 2000 and cut it down or if I could just get one pre-cut?
