Formal designation for Mega-V T-slot table?

[martin]

So, I find myself noodling about with workholding for a few of my machines, and I've started to mull jigs.... long story short, does anyone know the formal designation for the T-slot table extrusion used by the Mega-V?

If it's possible to do so, I'm mulling buying a couple of extrusion pieces myself to saw apart and use in various jigs and specialized workholding (for example, I've found it pretty useful on various occasions to have sections of T-slot that exactly match the slots on my metalworking mill. Makes it easier when doing weird angles and indexer work). In this case, I think it might be nifty to move a clamped piece among my various machines to/from the Mega-V without having to re-locate features all the time.

I've measured the various dimensions of the Mega-V table, but I'm entirely unfamiliar with aluminum extrusion nomenclature, so if there's a standardized name I could use when looking around for suppliers it would be MUCH easier than constantly trying to explain my measured dimensions (like trying to explain an O drill geometry vs. simply saying "do you have any O drills?").

...err, if this is a custom extrusion or something then obviously I don't wanna be a jerk and "steal" it, but if it's standard it'd be nice to know.

Would you mind sharing the dimensions that you documented?

Sure, with the caveat that these are all single-location measurements (I didn't sample across the board), I've rounded things (I figured tiny fractions were "noise" and measurement error off of larger nominal values, so I call 8.04mm as 8mm) and I only measured the bits of direct immediate interest to me:

8mm slot width at the top
9mm slot depth
1.9mm thickness of the upper surface at the top of the slot (this is the overhang)
22mm width of the "flat" of the top (so looking down on the table you see 22mm of flat aluminum, then an 8mm gap, then 22mm of flat, another 8mm gap, etc)

Thank you Martin that's perfect!

So, to potentially answer my own question, I suspect that the table pieces are Misumi HFSQN4-15250. It's a reasonably popular table extrusion (the Shapeoko folks often use it as an upgrade, same with XCarve).
