[Elecraft] K2 build question

[Tim]

Ladies and Gents,

I am in the process of mounting the crystals on my K2 RF board (Page 54 of the manual).  I'm having difficulty in getting a good solder joint on the grounding wires for crystals 7 - 11, the ones that are to be grounded on the sides of their cases, rather than the tops.  If I were to do it over, I'd solder the wires to the cases before installing the crystals on the board, but it's too late for that now.  Are there any tricks to attaching the grounding wires?

Thanks es 73,

Tim - KX3H
