Thanks Jamie and Len,

Butkus if great - first place I went, but thank you for the link. People spend a lot for manuals, when a small donation will get them what they want.

Well, there is brass and then there is brass. The trick is to get the metals matched and all playing nice. I am no expert at this, but the fact that yours works fine, Jamie, is useful information. Stainless (also many types) can be a bit of a challenge to the duffer (me). I'll pm Ron and see what he thinks.

Thanks again guys.
