The construction is done on the work surface and lifted onto the peel (super peel). I suppose you could do it on parchment paper and slide that onto the stone, but it is better naked. I have not and really would not try it with a regular peel, at least not without parchment underneath it. This is a substantial mass!!!
If anyone would be interested in seeing the assembly and loading (compressed a bit), I can send you a small video file ~ 2.5 MB.
