Hey Franco
No problems
I ended up finding some grommets that +I think+ will work...
Mockett.com sells grommets for Office furniture, but the sizes are just about right
Here's a 2.5" Metal grommet (works for flight sticks, maybe some trackballs with some jiggering)
http://www.mockett.com/furniture-hardware/wire-cable-management/metal/mm4a.htmland here's some small plastic grommets that appear to work very well for standard joystick holes
http://www.mockett.com/furniture-hardware/wire-cable-management/round-plastic-grommets/og.htmlThey look good in black, and the lip of the grommet serves to hold the dust washer off the surface, helping to prevent telltale wear around the joystick from the dust washer sliding around all the time. For most cabs, this probably won't be an issue, but, just in case anyone does have a need for something like that...
They aren't exorbitantly expensive, but with shipping, it's a bit more than I had hoped to spend, but not too bad, about 20$ for the big brass ring and about 15$ for 5 small plastic grommets for the sticks. Basically, an expensive detail

I'll post pics once I get things fitted properly.
