Case assembly

[Tony]

Bag2 (Bolts) and Bag3 (Case parts) are needed now, plus the assembled PCB and nixie.

After sanding and polishing (if required) the case parts start assembly by sticking the 4 feet from bag2 to the base piece as shown here:

[Tony]

Push the 4 bolts through the base holes - don't use washers - and turn upright:

[Tony]

Drop the PCB and back panel in, you should find the sticky rubber feet help hold the side pieces in place a little. Check the 2-pin connectors at the back can be used with the power supply/relay connectors you have, you may need to enlarge the opening for some connector housings to fit through:

[Tony]

Then the other 3 sides. Use one or both of the rubber feet from bag1 on the inside sides to hold the pcb in place:

[Tony]

Drop the top panel on, the side pieces will be held in place by the notches:

[Tony]

Finally the lid covers the notches, use the 4 washers on top:



And hold it together with the dome nuts:

[Tony]

Trim the HV wire to the shortest length that will allow you to still attach it to the nixie and solder it to pin 11.

Push it into the case, it should be tight enough to be held in place but still fit flush with the top panel.
