It is an absolute requirement that CD platform is machined with platform mounted on a shaft, otherwise you will get wobbling problems. For that reason, it's advisable to machine the parts from relatively soft material, like Delrin or acrylic.

The whole batch of Delrin platforms that is shown in your attachment was screwed up and not possible to use only because the shaft holes were drilled last.

I understood that 47 labs mount the platform on the shiga spindle and then have a little attachment that takes a final shave off the mount and puck so that its centered accurately.

I believe that issue can be eliminated if the critical diameters are cut in the same setup as the bore. It will take a bit more material to do it that way, but you should be able to do it.

1) setup stock in a collet
2) drill, bore then ream the shaft hole
3) turn bottom side features
4) turn the top side mating face and center hub ( where disk locates)
5) turn the part around in the collet
6) finish top side features ( thread etc.)

Yeah I have one of those.. It was also so slippery that I had trouble tightening and loosening the puck..It wobbled badly. The wood one with brass threaded insert I have now works pretty well, a bit hard to get on and off in winter, but otherwise fine.

It's a CD Pro with a display board Brian GT designed for his school project (limited functionality though).
