Mark III Premium Base (1)

Stage 1

Place the Top Cover upside down on your work surface. Insert the Switch Cover into the hole at this location, as shown:

This Switch Cover has a flat edge that matches the D-shaped hole (arrow below). Make sure this is fitted into the correct hole, as indicated by the nearby posts for the Printed Circuit Board (circled below):

Fit the Switch Button into this matching recess of the Switch Holder, as shown:

Turn the Switch Holder over and carefully align its screw holes with the two posts on either side of the Switch Cover, as shown:

Secure the Switch Holder to the Top Cover with two (2) EM screws.

This is your friendly reminder to try using 3-in-One Oil on all screws going into metal:

Stage 2

Position the Printed Circuit Board over the four posts at this location inside the Top Cover, aligning the screw holes as shown.

The corner of the Printed Circuit Board with the ‘SW’ text printed on it (arrow below) should be closest to the Switch Cover:

Secure the Printed Circuit Board to the Top Cover with four (4) HM screws:

Connect the plug of the Switch Button into this socket marked ‘SW’ on the Printed Circuit Board.

These plugs are keyed to only fit correctly one way. Take care to ensure the proper fit and do not force them into place:

Thoughts


Ah, the first pieces of our Premium Base are now assembled. I can not get over how heavy this metal Top Cover is (and how big). We can already tell this base is going to huge and weighty. I am hoping that I will have someplace to put it!
