I've got (8) 7.5# log molds now. Tried using a slab mold in the beginning because I love the swirls you can get, but I could never get the bars cut to my liking (liking=straight..lol), so log molds it is for me. I'm lucky in that my DH makes all my stuff for me, so if I need new..I just send him out to his workshop. Poor DH, lol, I'm like Goldilocks.. I've got 4 or 5 molds he made that weren't "just right".. too long, too short, not tall enuf.. ahh, now we're just right! Those molds just sit, I use them on occasion to tilt pillars
