I'm after some castors, as follows;
- They have to be of a suitable appearance for a sitting room, so furniture/office style, not those pressed steel ones for warehouses!
- They have to have a single, threaded, M6 stem/spindle. This is not negotiable, since the speakers they're going into have M6 threaded bushes in the bases.
- I'd much prefer ones with soft tyres, since they're going to be standing on a wooden floor.
After a number of hours searching, I've been completely unable to find anything that satisfies both requirements 2 & 3. I can find hard tyred castors with M6 spindles or soft tyred castors with M8, M10 or press-in spindles, but not both.
Can anyone help? If I can't find a suitable castor, I'm going to bolt on a wooden plinth using the M6 bushes and screw castors to that, but I'd really prefer a castor (well, 8 of them) that fits directly.
