Hi Bob, 

This is exactly what I did on my TC. It hasn't seemed to make any difference to
it's performance.  see 

 www.geocities-dot-com/rcopini/ 

If you look closely, I have a solid piece of meranti dowel 
sticking up into the base of my secondary where it is 
unwound. I am going to investigate changing this with some 
heavy plastic threaded rod and do exactly what you propose. 

Best Regards 

Robin Copini.
