Curious why a couple of electrical engineers chimed in and said they liked it...and said "good job". I agree, Midnite should do separated lugs. As for "creep"...will keep an eye on them and trim/re-do when needed.

You halfta love engineers! Sometimes they can be confusing though, maybe overthink things?

Much like getting a handful of electricians to interpret the Electric Code!

Seems no 2 will agree on the meaning of some parts.

Makes life interesting, at least.

Do NOT mistake me for any kind of "expert".

I also dropped the philistine screws / slot & updated them to torx

This is a close list :https://en.wikipedia.org/wiki/List_of_screw_drives



I picked Torx over allen  since there is no metric or (USA) No one else  makes imperial enmeshment bolts .
Try finding Imperial / UNF /BFT type thread out of USA or Canada ..

AND Just for the record
I don't like the midnight terminals either.  The Breakers on the other hand, with the screw that pinches a saddle over the wires, bunching them together, instead of trying to drive a screw through the middle, Much better wat to terminate, I wonder if they used those on the B17 ?

Solder/Crimp 
I hydraulic crimp only.  Solder, it's real hard to control where in the wire it will wick to, and where it stops, is where the wire breaks.   
All spacecraft power bus wires are crimp only.  Lots of tin/lead solder used on the boards, but not connectors.

I also purchased ferrules from ferrulesdirect.com...both 4 AWG and 10 AWG.  (I actually thought I had gotten 6 AWG but had apparently written down the wrong number.  Rats.)  Anyway, I could not get the 4 AWG ferrule to fit into the Midnite Classic terminal block.  I do not have "professional" crimpers so that may be the problem.   I do not have calipers to check the opening size and compare with the ferrule sizes listed.  Again, that may be the problem.  Ferrulesdirect was great with their shipping speed and prices, by the way.  I'd order again from them.
