[Alex, Daniel]

I designed some custom plates that mount to the Agilent Base Plate and allow POC001 Caster Wheels to be attached. We had 4 of these caster wheels around from the SNSPD Dewer Cart. The purpose is to move the vacuum pump system along with the dewer.

I attached the wheels to the plate with the 4 M6 screws included with the wheels. I attached the plate to the Agilent Base Plate using a 3/8-24 hex bolt (and a lock washer) from the "inside" of the Agilent Base Plate. I also used a #10-32 set screw to help align the custom plate into the Agilent Base Plate since there is a rotational degree of freedom.
