Group: Forum Members Posts: 15, Visits: 189	I think I have settled on bladder molding a two part wet layup for the duct. I need to figure out a way to make a reusable and sturdy bladder. Ideally out of silicone. Rotomolding is an option but I would have to build a machine to be able to do it. I wonder if I can sneak perforated peel ply and something absorbent into a stack between the bladder and the carbon to pull off some excess resin. The other option I was looking at was oven curing with a silicone plug inside the part that would expand and create pressure. My garage is ~560 square feet and I have to be really careful about taking floor space. Safe ventilation would be an issue since my living room and kitchen are above it. I am also not sure how easy it would be for me to get the silicone part back out with the shape of this part. I do have a fireplace in the garage I could run aluminum ducting through...

It is a dual stage rotary vane and the listed specs I could find are 3.5cfm and 10^-4 torr (which if I undestand vac units correctly is about as close to 30" of mercury and you are going to get). Has anyone done vacuum bagging work with old lab pumps?

Group: Forum Members Posts: 15, Visits: 189	Also, has anyone worked with 3d printed molds before? I have been using ABS plastic for everything since it is reasonably resistant to heat, however large prints will almost always warp so it seems like a poor choice for a split mold.

Group: Forum Members Posts: 15, Visits: 189	What is the best way too approach doing the duct part if I don't want to sacrifice a $80 3d print each time? Most split mold techniques I have seen require being able to fit your hand into the part but this is too narrow. I could do it in two pieces and bond them but that seems like it will be difficult to get a clean joint.
