In this installment you are going to mount your electronics layout board to the side of the machine.

What you will need

  • 2, 2” Hinges

  • 4, 10-24 x 3/4” Coupling nut

  • 4, 10-24 Hex nut

  • 12, 10-24 x 1/2” Machine screw

  • 16, #10 washers

Before attaching the layout board, remove all the cables connected to the G540.

Install the Hinges

Start by placing the hinges three holes from each side as shown here. Secure with a #10-24 x 1/2” machine screws, #10 plain washer and 10-24 hex nut.

You can purchase the hinges here:

2” Steel Hinges

Use a 3/16” drill bit and drill out the other hinge hole as shown here.

Secure the second hole with a #10-24 x 1/2” machine screws, #10 plain washer and 10-24 hex nut.

Install the First Standoffs

Add a #10 washer, 1/4” washer to a 10-24 x 1/2” machine screw and insert it into a hole in the right shelf support bracket as shown here.

You should use a hole that is approximately 1-1/4” from the leg.

Add a 1/4” washer.

Screw a 10-24 x 3/4” standoff on the screw as shown here. Keep it loose as you will have to fit them to the hinges.

You can get the standoff (coupling nut) here:

10-24 coupling nut

Add a second standoff about 1-1/2” from the first. Again keep it loose.

Attach Layout Board

Place the right most hinge on the layout board against the first stand off and secure with a 10-25 x 1/2” machine screw and #10 washer. Keep it loose.

Move the layout board to determine the location of the standoffs.

Add the standoffs and secure the layout board.


You can add some eye bolts, chains and S hooks to support you layout board in the raised condition shown here.

This makes it easier to work on your board.

At this point you can reconnect your cables. However, if you are going to add the E-chain, you may want to wait.
