Nope not pc board.
I started out making my own spikes but a couple years ago ME
started making their micro spikes. They work perfectly for code 55.
I have a battery dremel copy with a cut off disc sitting right by
as I'm spiking. I put the spike in the pliers holding the head
then touch the bottom diagonally to the disc and it quickly puts a taper on the spike
then insert the spike. Easy simple fast accurate and unlike soldered pc ties
the rail can move back and forth as it contracts and expands.
