Group: Forum Members Posts: 8, Visits: 63	Fellow Composite Companions I have the hull of a 7.2m long canoe and was undecided of the locations of the resin feed in lines and the vaccum out lines. My questions are; for this length would a couple of lines in & out work better? draw the resin from one side to the other rather than nose to tail which is longer? Resin feed from the bottom centre of the hull and draw to each end. Yours, Undecided

Run spiral completely around the outside flange with a brake zone. Number of feeds depends a bit on the laminate stack and your resin. Longer pot life you can use less feeds, shorter ones and a thicker stack use more feeds. A general rule of thumb that I go by is 30 minute pot life = 1sqm maximum; 60 minute pot life = 2sqm maximum; 90 minute pot life = 3sqm maximum. Divide your laminate into sections that big and then you can work out how many feeds you need. Edited 9 Years Ago by Hanaldo
