I think if I would have made it a bit thinner it would have worked that way. The one I actually showed cutting on the video had relatively flat sides and probably would have worked as well. Typically when I try to make the base as small as possible, it’s easier to cut them for quick removal. The way I pour them with foam I find that the flashing just rubs right off. If I were casting in resin or some other hard material I may think twice about cutting them.
The plaster will not stick to the silicone. If you are referring to the two halves of the shell It does overlap. The petroleum jelly will keep it from sticking. As long as the overlapping side does remain flat it will come apart. If I would have gone to far over the seam it would then cause an issue and lock together. Since making this video I have changed my technique a bit and no longer add that green ridge. It helps with making a better overlap.
I used the plaster bandage on this mold just because it was quick and easy, and to use up some of my supplies. These three molds that I was working on were small so the extra wight of plaster was not a concern. I prefer the fiberglass for durability and when the molds get larger, plaster can become heavy if you are roto casting by hand. If you are comfortable using fiberglass they will last longer and can be repaired if they crack. Another consideration you may want to think about is ventilation, with it getting colder here in Michigan I would not want to do fiberglass in my garage without the door open. If cost is not a concern, you should check out Freeform Air by Smooth-On they have some great videos. I have used it on one of my largest molds and it was easy and really light weigh. The only drawback was the cost.

Thanks for doing these.
Glad you like them!
Very nicely done by the way
Thank you!
How come you split the mold rather than just peeling it off in one piece? I figured rebound would stretch

You CAN overhang but release the overhung part with Vaseline
Thank you. I did have a bit of an overhang but not much. I think next time I will try it without the center key to keep the seam a bit cleaner.
How did you get the gauze to separate from the silicone? It looks like you overlapped it on the green ridge.

Very cool. One question though, why the bandage rather than fiberglass? (Im just getting into concrete molds). ✊🏻
