Does the Oil free diaphragm pump you linked have a “Vacuum control switch” or is that something separate?
Made first attempt pressing a deck but I had a small leak and considering a better pump

The pump Didn’t have a switch.
I bought the f4200 switch I listed from Coast Pneumatics. It is adjustable for different vacuum levels. It plumbs into the vacuum system and wires into the pump to turn it off and on.

If I want to make my fiberglass enclosure have some flex, how many layers, what type of fiberglass cloth, and what type of resin would you guys recommend?
It totally depends on the design of your enclosure and the materials you use.
And for the most part, it comes down to practice, patience, mistakes and experience. Can’t really comment on the flexibility part because i haven’t used anything that I’ve made for long enough to determine it’s durability.
@BigBen or @eBoosted may be able to better comment on a good recipe for a flex enclosure, but it would help to see a picture of your rough idea of what the enclosure is going to look like.

The enclosure design will be fairly standard with a dimension of 21"x9". The deck has both camber and concave and I would like the enclosure to follow that camber and concave. The battery is able to flex laterally and longitudinally so that it follows the concave and camber of the deck. I don’t think I will be able to get the concave and camber of the enclosure right if I use a foam mold so I’m considering using the battery+putty for the mold or shaping a piece of wood. Unfortunately I don’t have a vacuum bag and I don’t want to spend for one when I will only use it once. I’m thinking fiberglass because it follows the shape of the mold really well and will allow me to get a perfect seal. I just need to figure out what cloth and resin to use.

If i were you I would make a timber buck like you suggested and use 200gsm cloth, 2-3 layers of 450-600gsm woven roving, and another layer of 200gsm cloth.
You can see photos of how I shaped a timber buck in this thread Demonseed 44 Enclosure

And use epoxy resin. Polyester stinks

Thanks, this is super helpful, that’s a lot more layers than I was thinking.
@eBoosted uses a special flexible resin on his enclosures but when I asked what it is he said he knows a guy who makes it, so it’s a special blend I guess.
Nearly any epoxy resin should be fine.
And also, my recommendation may be way overkill 
thats just how i would do it.

do you mean figuratively? or the smell is really that bad? it seems polyester resin is cheaper here so I almost bought some once but thought that if noone recommends it, it must be really bad.

It really smells and is bad for you. If you use it, use extraction and a mask made for the job.

hey, as long as you are making the enclosure, is there a way to make it so that you avoid this battery design? I think that’s a huge advantage of making your own enclosure is it can be made to fit the battery better
@glyphiks I love your top mount enclosure mold, have you tried to pull a part out of it? Would be cool to see more of these out there in the world

The one on the 4wd is one of a kind 
the mold I made for it was only ever meant to be single use and it was well and truly destroyed while demolding
I have molds for these guys, but they aren’t as fancy. In the future I’d like to start making enclosures for others, but right now I’m not properly set up for that.
