Nice LOL...You are not the first, and I have discussed this with my
shop. The thing is that the bottom cap is an insulator and it it was stainless it could/would short out the unit. We could machine in a delrin cap of some sort but it woul also extend the length...I guess I willl have to talk to one of my machining guys and see if they can come up with something. Thanks and nice looking rig you have there.

ps Actually I just looked at your pic again and realized you may be talking about the top cap!!! I will stil ask my machinist...
