David,

Just follow the instructions in order and all will be well.  You must 
flush cut the relay leads after soldering, and that will not be easy if 
you mount the capacitors first.

When it comes to the capacitors that fit above the relays, yes, you will 
trim the leads before soldering as instructed in the manual.  The 
inductor leads are similar - just follow the instructions.

I noticed that other caps go into holes that will be directly under the relays on the other side of the board. My dilemma is that I am concerned that if I don't install those caps BEFORE installing the relays, I run the risk of piercing them with the leads or having solder go through and melt them. I know how fragile the relays are because I nicked one with my soldering iron when I built my K1. It had to be replaced. Conversely, if I install the caps first, I run the risk of not having the relays sit flat...even if I trim the leads beforehand. I know this is a critical issue as space is at a premium on the boards, and it has to fit with it's control board within tight tolerances. Should I follow the instructions, or deviate slightly so I know I won't damage something? The KAT2 is quite possibly the most important option one would
