    This is the original Darnell design for sealing the control rods as they go through the radio box wall...it works, I've used it more than once, but is there a better, more up to date way of doing it on a cylinder? Or do I stick with the old school method?

    The Great Man had some brass rod drilled and a thread cut on to one end, this was so that he could then screw it in to the bulk head with an "O" ring making the seal, the rubber bellows were then placed onto the other end.

    He used this on his type 7 and it worked very well.

    Sorry should had said that it was a hexagon brass rod that he used, this was so that he could then use a small spanner to screw it into the bulk head.
