1. Start by creating a 90 degree bend about 2 cm from the end of the rod. This allows enough room to clip the end down to the correct length later.

1. Insert the bent end into one guide hole, and, keeping the rod as flat to the board as possible, use the second guide hole to estimate the position of the second bend. Your estimate should be about 1mm short to allow for a bending radius. Once you have the pliers positioned on the rod, make your 90 degree bend.

1. Look along the length of the rod to make sure that both "arms" are in line. If necessary, align the two arms by twisting about the axis of the axis of the rod.
1. Test the fit of the rod by inserting it into the guide holes. You can see, in this example, the rod is a tad long.

##### Longer Stabilizer posts for Futaba
The Futaba aligner PCB includes two stabilizer posts, allowing the futaba keys to be used with the Cherry MX PCB-mount stabilizers.

1. Remove both posts from the PCB. Newer revisions of the aligner board include perforations for easier break-away of the posts.

1. File away the area marked "File to 1.5mm". The aligner includes a thickness gauge to test fitting, but it turns out that manufacturing tolerances are not adequate, and the gauge is not reliable. Use a spare key to test the thickness. The post should require some pressure to inert into the keycap base.

1. The post should be just under 4mm wide. The post in this example is an early revision that was specified at 4mm, and ended being a sliver too wide to fit the keycap base. It required a alittle extra filing along one side to fit properly.

1. The posts should be just tight enough to require a pair of pliers to insert. Use pliers to insert both posts fully. Use a ruler or caliper to ensure the prodruding portions of both posts are the same length.
