Pat, thank you for the tips. As you can see I may have already gotten ahead of myself with the shaping of the layout but I will make note not to do so until floor tillered on the next one.
Thanks guys!
Oh, Sadiejane...you don't want to see my steam rig. I "copied" the one that Gary Davis shows in his DVD, however, been a cheap, dumb, dutchman I decided to save $6 and purchased cheap, flexible 4" dryer vent to attach to the 4" galvanized T (should have followed Gary's design to the letter) so after an hour of steaming the flexible vent had low spots that trapped all the condensated YELLOW steam/water which then proceeded to pour out onto our white stove and rug
My wife is still quite pleased with me...
Anyway, note to self...use the steam rig on a hot plate or the grill outside or in the basement from now on.
