Well here’s my plan for the slotted panel - 6mm slot on the topside with 12mm diameter holes in the ends. 12mm slots matching below so you can pop in a 6mm carriage bolt and the square bit will bind in the slot. Or you can use regular hex bolts and adjust the slot at the bottom to suit. Of course you can add slots to taste and it’s not costing anything but a bit of machine time. I can’t see the point in spending money on tracks, and while you probably can’t flip this one over - it won’t cost very much to replace.
Who knows, might even burn in a grid (not this one) and a bit of branding if the laser gets up and running before I get around to this.
