Yup I am using 18 ga. Sometimes it feels like working 3/16 steel. You are right It will probably be stiff enough that any flexing etc will be absolutely minimal.
IDJ, Good idea about mat and dots. It would be a perfect time to add FatMat or a reasonable facsimile and have it insulated to boot. The dots are a good idea..
I love coming here and tossing ideas around. There is a wealth of information to tap..
Thanks guys, Now back to work or "No Soup For Me"
