Had a bit of time this afternoon so got the perspex top done with drilling and tapping 2 off M3 threads on each sink so the heatsinks are all aligned.
Now as it been suggested using both pads on VS1 and VS2 which will a tight fit for wire so just squashed some 1/2" copper tube and ended up with 18x3 mm so I could make a bussbar and put 2 of those M4 connectors on each pad then bring it out for the external connection to thick wire.
Now just cut some 3/8 and 1/2 copper up where the 3/8 copper just slid in, heated the copper up to bright red to anneal it then gave a few smashes with my 4lb hammer where I got 18x4.5mm
Also the battery connection under the board can be the same where a copper bussbar is made.
Now for the PCB stand off's got 12 of them to make so that box of M3x12 SHS will come in handy for securing everything.
