So just for example if everything weights 200g Il have to mix 200g resin?


The 50/50 really means "equal/equal", so if the cloth weighs 150grms then it needs 150grms of resin to give the 50/50 ratio. Because the peel ply and flow mesh also have resin uptake then you need to allow for that. That's why Chris said weigh everything to take that into account. So whatever the total stack weight is match that with resin. You also need to allow for the resin feed line as this will retain some resin, obviously that depends on the length of hose. I usually add on about 10%, this should allow for the feed line and leave some in the pot, you don't want to cut it so fine that at the end of the infusion the end of the feed line isn't in the resin and pulls air in. With infusion if you see that the resin level is getting low, clamp of the feed line mix up some more resin in a fresh pot and carefully pour that in. You can then release the clamp and finish the infusion. Try and keep the feed line as short as possible to reduce wastage. With experience you will get a feel for how much extra to allow. You can usually tell within the first minute or so if you are likely to run out of resin, look at how much resin has left the pot and compare that to how far it has traveled through the part. You can then start mixing up some more resin without having to stop the infusion.
Hope that makes sense.
