Taking apart a Black Widow Tonearm

After several attempts at finding tubing for the wand I have got the correct size tubing both of Aluminum and Carbon Fiber. The problem is when heating the original tubing nothing is happening to remove it from the Chrome fixture. What is worse is that I lost the broken off part with the headshell I'm not very happy.
Can anyone of the experts tell me step by step how to recreate the wand arm like new?
