We recommend using 18mm MDF for the Spoilerboard. This will give a maximum cut depth the whole way through of 44mm.
-
Cut the Spoilerboard to size following the dimensions given here: here
-
For the 1500x1500mm ideally you should try and source a 10' x 5' sheet of 18mm MDF.
-
At each end of the Spoilerboard, 10mm in from the edge, drill four 5mm Diameter Holes. One in each corner, and then evenly spaced in the middle.
-
For each hole drill a 10mm diameter counterbore, 11mm deep.
-
-
-
Using 8 x M5-Button-Head-Bolt-12mm and 8 x M5-Drop-In-Tee-Nut secure the Spoilerboard to the front and back Extrusion-A's.
-
Make sure the M5-Drop-In-Tee-Nuts are engaged with the slot on Extrusion-A.
-
A good technique, is to tighten, then loosen the bolt, then tighten, each time tightening a bit more. This helps the M5-Drop-In-Tee-Nut to engage with the slot.
-
Once you have the Spoilerboard in place you use a variety of methods to hold down your projects.
-
The UJK System from Axminster is very good.
-
Or you can also do a pronged tee nut system.

It might not be right but I made the countersink hole more shallow and used a longer M5 Bolt (16mm) with a washer below the cap to hold the spoilerboard down…
Still was quite difficult to get the Tee-Nuts to engage properly.

Hi Ryan, I found a countersink depth of 15mm a bit too deep as the M5 x 12mm bolts bottomed in the slot. I reduced the countersink depth to about 12mm and was pleased with the result.

Hi Ian, You are correct 15mm is too deep. We have changed it to 11mm Counter Sink. Robert
