Re: [ATM] wire spiders

["Alan Scott" <alanne1956@hotmail.com>]

Mel's wire spider is beautiful.  I have seen it before, but it is nice to 
see once again.

Since I am using only one ring for the upper "cage", I do not have the two 
contact points that Mel has.  So, I don't believe I can use his crossing 
design.
