I have been asked about components, the "off the shelf" spacers were obtained on Ebay (long lead time from China), search for "M2 Tapped Brass Stand-Off Pillar", I got 8mm, but had to add washers, so perhaps 9mm might be better. Screws are all M2 x 6mm (countersunk and pan head), the aluminium extrusion was cut from a meter length of 40mm x 10mm, available only at larger B and Q stores. As you can see from pictures, I had to pack up the height with wood, to get the right throw, but that is because my boards are only 6mm ply, should be fine on 10mm+ thick boards. Washers are needed with the mounting screws, so the holes can be oversize and allow final positioning.
Final adjustment of micro's was finicky, so although self tappers would do, the holes would need to deadly accurate. I ended up elongating/widening the holes to give the right position, but as I used nuts and bolts, hole size does not stop them being clamped in the right position.

No problem, although I forget were I get things as it was quite a while ago and what I got exactly! The screws for the pillars should be shorter, probably were 4mm or 5mm long. The hardest thing to find was nuts! I bought them in 25's of washer, star, bolt (10mm) and nut kits. http://www.ebay.co.uk/itm/M2-M2-5-M3-M4 ... 35d0f84b0c, others from http://www.ebay.co.uk/itm/Hexagon-Full- ... kBhY1de73A and again http://www.ebay.co.uk/itm/M2-M2-5-M3-M3 ... js6nBerG6Q
