OK, let me be waste everyone's time and explain why I got upset with the post from Jeff. The main purpose of my post was to show the members what I found is a cheap and better alternative to any of the chucks we have been using. Jeff took quotations from my post and used them out of context to put a negative spin on my low cost spindle idea. He used cheap Chinese spindle to mean garbage with excessive run out worse than the QC. He then, quoting that since my bearings were not ceramic, that the project was not really worth it. I think both of these statements are malicious and untrue. I would have been ok with this if Jeff had come back to continued a positive discussion. When he did not reply, It seemed to me he was just trying to end the thread.
The China spindles are precision ground hardened steel. I will bet that 95% of the reputable American spindles are also made in China. The ebay spindle for $25 is probably the same as the American one for $60.
To my knowledge, all of the Carvewright machines have steel bearings. They easily last if they are set up right with a slight side load between them. I do not know if Carvewright has ever used ceramic bearings. My guess is that they have not, and, that makes the need for ceramic bearings a red herring in this thread.
If I had mistakenly offended a member on the forum, I would apologize - not try and defend myself by further quoting and attacking the member as being unreasonable. (Even if true!)
If I was a moderator who has a company selling carving bits in competition with LHR yet I was able to advertise my company on the forum, and further, my company also sells an ER16 collet holder which is “compatible with the Carvetight”, I would be careful not to appear biased.
In a post some time ago, I was trying to explain how take the QC completely a part and how I thought it actually worked. I was explaining the function of the two half rings which fly out against the taper of the outer sleeve and force the sleeve down. This action holds the adapter tight. In the case of a low rpm stall the fly rings do not work and, the carving bit with its downward pulling helix can yank the adapter right out.
Jeff replied that it was simply the balls that hold the adapter in. He implied that my whole description was garbage. How far is a post going to go after a moderator slams it. I over reacted then as I have now.
