I plan on doing a couple of mods I've mentioned here
http://weberkettleclub.com/forums/member-sales-trades/seeking-rusted-out-kettle-2-messed-up-lids-chicago-area/I thought I'd ask for tips or tricks for drilling & cutting porcelain coated steel as I'm sure it's been done many times.
If nobody has any suggestions, I'll try using the method for drilling holes in ceramic tile as it seems like there would be similarities regarding drill bit or saw blade/grinder getting a decent grip instead of bouncing around a bit. If I go that route, I'll report back with my findings. For drilling a hole in ceramic tile, you basically take a couple of pieces of masking tape and place them in an x right over where you are going to drill. It probably does not really need to be an x, probably just having 2 layers is really all that is needed. Basically, the drill bit goes through the tape which gives is a bit of a grip & helps prevent it from bouncing around on the smooth surface before getting a grip. I'm guessing it would similarly help if using a grinding wheel or a saw blade.
I'm kind of guessing a grinding wheel will cause less damage to the porcelain than a saw blade.
In any event, I appreciate any suggestions.
Also went to a thrift store & picked up a used $2 stainless steel mixing bowl to cut the bottom off of to try out as a vortex thing. I was looking at one the other day thinking it should work, then found a couple of threads on here where people had done the same thing.
Eventually, I might try the comal pan modification drip pan for use with a vortex that
@Jules V. did on his poortex/vortex thread. Really looks nice, but I figure I'll have to see how much I like homemade version first.
