+x Steve Broad - 1/29/2019 6:18:46 PM+x quinn - 1/29/2019 4:35:57 PMBeen doing a little more reading and feeling a bit less confident about the latex bladder. Seems that latex isn't all that resistant to heat and deteriorates pretty quickly. I already have some wax sheets that I ordered a while ago when I was planning on making my own bladder, so I went ahead and ordered some silicone too so I'll also have that option. The thick sausage type party balloons survived 120 deg C with no issues.

The thick sausage type party balloons survived 120 deg C with no issues.Ok good to know. It sounds like latex can work well, but maybe not for that many repeated cycles if using a more permanent reusable one. I guess even if I use the latex bike inner tube, it's still only a few bucks for each one. Maybe use it a couple times or even use a new one each time. Not a big deal. Having a hard time finding balloons that are long enough and expand enough at the large end. I ordered some "rocket balloons" on Amazon and they inflate enough to fill the cavity, but they are just about at their limit at the large end and they aren't very durable. Large end is 40mm×46mm.
