After a lot of discussions with the glass shop about how 2mm glass is too thin and very easily broken, I ordered a circular piece of 3mm glass to be used for the working surface of the Samtiq. The glass has 3 holes drilled in it and bolts into the wood underneath it and then the little metal knobs screw ontop of that to hide the bolts.

I started by placing the glass on top of the Samtiq and marking where the screen was going to be. I then masked off the underside of the glass and started painting the glass black. Oh I made a Samtiq logo stencil and painted that orange before going over it with black. Need to wait for the logo to dry completely before starting with the black, which I didnt do and so I had to do a bit of a fix up later. Anyway it will look really messy painting the back of the glass but when you turn it around you get this even smooth colour (just like they used to paint animation cells). I had to do 4 or 5 coats of the black to make sure all the holes were filled. Here is a shot of me painting the glass:

Then I just marked where the bolts were going to be and drilled the wood and that was it. I am happy with the look of the unit now. Since I have the protective glass I can now use full pressure without worrying about damaging the LCD, although the glass is a bit too smooth and doesnt have the grip feel of paper but I hear that the felt nibs from wacom help with that. Here are more shots of the unit:

    Rumi,

    Lovely result, very much along the lines of what I would like to achieve. I have a traditional animation desk from Disney and I would like to gear my build to fit in the standard acme disc hole already in the desk.

    The thing I notice about your build and what I would ask is the diameter of the final disc, looking at your photos it seems quite large. Much larger than would allow for my desk. This seems to be derived from your having that bit of the monitor cards laying flat above the lcd itself along with the ffc running flat off to the left as well.

    I wonder do you think it would be possible to build so as that bit could rest more at 90 degress, swept back from the monitor? Since the goal is not to make it as thin as possible but rather control the overall size of the disc.

    Was it an issue of interference/shielding to have it configured like this?

    Many thanks,
    J.

    Hi Jthomasc,

    The diameter for the glass top is 605mm. The longest side of the Wacom sensor PCB is 425mm and for my calculations I assumed I was fitting a 425mm x 425mm into a circle. The diamater of this circle would 600mm. But the sensor is not square so the circle is actually a little bit bigger than is needed but not that much.

    You are right that controller board and inverter boards can be mounted vertically but they are just filling space which would otherwise be empty because we are fitting a rectangle inside a circle, there is wastes space around the rectangle. The limiting factor in terms of size is the wacom sensor and not the LCD controller placement.
