Ravi,

That is what I do.  The bottom winding on my secondaries have a terminal 
soldered to them.  The secondary form has a plastic flange glued onto the 
bottom.  Three bolts go through holes in this flange into the plywood base 
that supports the coil.  Two of the bolts are nylon.  One is brass and goes 
through the terminal first then connects to the RF ground wire under the 
coil base.  The six inch diameter coil uses 1/4" bolts.  The three inch 
diameter coil uses #10 bolts.
