There are certain advantages to working at a hack space.  Namely my room doesn't explode.
This used to be a bedroom

Enough background.
At Jo-Ann Fabrics and Crafts colored glue was seen for a very low temperature glue gun.  This may be an interesting media.  A high-temp glue gun was purchased using a 40% off coupon making it it $1.80 before tax.

The shafts were removed and nuts were added so the sprockets would sit at the same level as the sprockets on the servo.  Washers had to be added since the top portion of the carriage bolts were not threaded.

A sprocket was drilled with a 21/64" drill bit.  A servo horn in a cross shape was drilled with a 3/16" drill bit.  The sprocket fit snuggly on the servo horn.

The matched sprocket and servo horns were put on the mounted servo so the height of the shaft sprockets could be adjusted.

The servo horns were held together by shoving toothpicks into the holes, trimming the picks and gluing them together.  The pieces were pushed together with an adjustable pliers.
