ForeverSpin's Spin Base take on DLC is not the same as the rest of the worlds. They are calling it a "Diamond Like Carbon" not "Diamond Like Coating". It is also different in the process. It is not recommended to use any tops but theirs. It does not matter if your bearings are Ceramic or Ruby, the ForeverSpin "DLC" Base will damage it. There are numerous accounts on the Spinning Top Facebook pages about it.

ctalonI think you misunderstand the term diamond-like carbon(DLC)-coating. It's one of the smoothest and hardest surfaces ever achieved by man - it's far harder than any of the metals they use for their spinning tops, so it probably *could* damage a softer ruby tip. I think that people are strongly exaggerating, I mean it's supposed to be absurdly smooth

GraboNo. I have no misunderstanding of what the material is.

ctalonYou'd have to drop a ceramic or ruby tip a fair distance onto the DLC base to do damage. I own 5 different ForeverSpins (including the quite heavy and durable tungsten) and a few specialty tops, including some ceramic and ruby tip. If you spin it close to the base, no damage. If people are dropping them 20 inches onto it...yeah...they're not making good choices. It's not that they aren't hard, but they do have limited fracture strength.
I think we forget what hardness/softness mean sometimes. It is the resistance of permanent form change, like a ruby sphere trying to stay a sphere, rather the flatten out. It'll resist until it fractures. Versus steel which will be more resistant to fracture, but will permanently deform at a significantly lower force, i.e. bend, flatten.
For tops, you want the hardness, as they will be more uniform and higher precision. But those sort of materials also will fracture shortly after deforming and therefore may not have high toughness (ability to deform before fracture). A soft but tough material would be a poor high-precision top, due to it's inability to keep an unchanging form.

PandemosYou do not understand what I am saying in my post. Please refer to Pocket top Talk or Billetspin on Facebook and refer to the rather lengthy posts that are there about the ForeverSpin DLC spin station damaging tops.

ctalonLink please? Genuinely interested. Scrolled down for about 5 minutes on Billetspin and didn't see anything.

ctalonI own the ForeverBase. I can't see any reason why the convex glass would damage tops. The edge does damage tops when they spin off the base. Stainless steel sharp edges, I wrap a thick elastic band around the top edge when I use it or sometimes tape.
