bmoran:
Thanks for your helpful info, too. I've downloaded all the pdf's from that page you linked and will file them in my PW "Tech" folder and read them prior to attacking my smoke units tomorrow.
Working on smoke units...
I recall working on PW smoke units way back during my "Hey-Day Years" of 3-railing, but that was some 25 years ago. I will have to re-learn all over again. I do remember unwinding 1 turn of the heater coil, but before I gleefully unwind a turn on these smoke units, I'll double check to make sure there are NINE rounds before unwinding down to EIGHT. I think I recall the top part of the unit is press fit into the bowl, no? (Can't remember how I separated the bowl parts.) What can I use for the little fibrous gasket that fits between the smoke unit and the body? (Clean the existing gasket as best I can and reuse?)
Batting...
I think I recall using some fiberglass insulation for batting. However, I don't have ready access to a small amount of that. What I can access is the "blown in" type batting that's up in our attic. Will that work? Or, do you recommend a supplier that offers superior stuff to either of my materials?
Questions seem to be multiplistic: 2 questions answered results in 4 more questions asked, etc. 
All fer now!
Andre
