Sean-Thomas, et. al
What effect do you think using a larger (next size up) floating bar at the 
leaf spring end, filing the top flat and securing the spring with a flat 
strip of brass across the spring end secured with the two 4-40 screws.  This 
would eliminate  the need for the square tubing.  I plan to use 3/16 bar for 
the fixed rod.  

Is it necessary to make a slit in the bar for the flecures or could they just 
be soldered around the rods?

At one point you indicated you were going to experiment with using stainless 
steel fishing leader for the flexures.  Did this improved the period? 

As always, your help is greatly appreciated.
