You need a vacuum!!
Without that, process will make you mad as hell, because corners will not stick. I recommend my style- I call it “GHETTO VACUUMING”! So items you need is:
-
Vacuum bag for cloth storage- they cost about 3-5$ it is strong bag with zip and hole for sucking out air (it has membrane inside, so air coming only out) . just choose right size of the bag.
-
Vacuum cleaner.
So that’s it, I invented this for myself, didn’t find this style anywhere And it works! First time when I heard word vacuum for carbon part making, the first thing that came in my mind was vacuum bags for cloth storage. My girlfriend is using them to save space in closet for winter clothes.
I made my enclosure and board as well with this style.
So process is:apply resin on your mold than apply cloth then again resin and so on. When you finish- just put your detail with mold in vacuum bag, press air out, close zip, connect to vacuum cleaner and suck out rest air, close hole with lid and wait 24h, and you done!!
One thing- outside of part what touches bag will have pressed out resin bumps in bag form, but you can sand it or probably you can use peel ply between part and bag. I heard that there is some kind of peel ply that sucks all not needed resin in, after you just peel that ply off and you end up with surface clean without deformation, but it will look like sanded, so not glossy. But I didn’t try that because didn’t know that peel ply exists!
This GHETTO VACUUMING works and it presses a hell out of that part in mold- So you end up with precise and stronger part due to compressing and less resin in your product!
One tip: Use resin as little as possible, just to soak the cloth!!! More resin you use- Uglier and Weaker part will be. When you mixing resin use same weight as cloth you are going to use.
So about 5$ you can get GHETTO VACUUMING system at home, isn’t it great! And you can use that bag over and over again!!!
