Gentlemen:
Thank you all for your C & C. I really appreciates it, especially those that pointed the mistakes. Yes, I have to admit there were certain fitting issue which is caused by over tightening of tail stock and also failure to checked the actual dimension of the parts with a pair of vernier caliper. During photo taking, the pen was position in such a way that these fitting issues was reduce to the minimum, it is only experience turners like you guys that are able to spot the mistake. To avoid all the above problems, I have actually throw away all my bushings and started turning between centers and using a pair of good quality vernier caliper to checked the part used for actually dimension. It is actually cheaper, faster and better to turn between centers.
As the pen in the photo is only the third pen I have turned, I have still alot to learnt from experience turners in this forum especially when it comes to segmenting which is actually my main interests.
