Here's a few pics.
I used 3 x C-774 Utility Compression Springs (made by Centurey Spring Corp or CSC). They provide a rediculous amount of tension compared to the stock springs. (See pic 5). And no need to buy spacers to keep the springs from moving, just leave the 3 x stock springs in there, and place the new springs over them! They keep the new springs perfectly centred
And you can just make out the 9 x black mirror supports. They are furniture spacers / supports from bunnings, and look like Cadbury Choclate squares - only black chocolate! I just used silicone to secure them in a standard 9 point configuration. (See pic 3)
And I upgraded both the mirror lock bolts and tension bolts, 65mm M6 from memory. They don't have to be sunked head, as the black mirror supports raise the mirror a good cm above the mirror cell. I also added wing nuts to the end of the lock bolts. I had to grind the inside of the wings for the head of the bolt to fit, and I secured them with a nut and loc tite. (See pic 2).
I drilled holes through the end of the 3 x tension knobs. This was easy, and done with a hand drill. I then test fitted the M6 bolts to see if they could pass through. I had to grid the inside of the head with a dremmel to make it super smooth for the bolts to pass through. (See pic 2). Alternatively, you could buy nice tri-head knobs from a specilaty faster store. They'll be easier to grab and will make collimation a sinch. But I was happy to mod the stock parts for now:

This mod pushed the primary mirror 2-3 inches up the tube, and will allow air to pass more freely around the mirror and up into the tube when the fan is used. It was kinda cramped back there before the mod. (See pic 3). I will be getting an MPCC shortly. Nice to know that I won't have to cut the tube!
Cheers,
Logie.
