Slindie Rabco arm

Yesterday I purchased a very heavily modified Oracle Delphi table and Rabco linear tracking arm. Mods are very well thought out and executed.Does anyone know anything about a Mr. Slindie or Slindy who lives in Wisconsin ( or did) and modded Rabco SL-8E's arms?
sonicaly am very happy with the result - just would like to know more about the guy who designed and built it and most importantly can he service them in the future?
