looks good! i always cut it exactly as shown in the photo (minus the extra cut in the bladder)
Thanks mate. Wiped with alcohol, stuck the new valve on and then glued around the edge. Left for 24 hr and now waiting for an opportunity to pump the kite. It’s a little thing but I’m chuffed to bits with a little bit of diy.
Greets, my first post and thanks for the lot of tips found here.
Here is one of mine. Check the pic. This kite has seen a couple years of action when I bought it as my first and learned to ride on it. Attached it as high resolution so If you close up U will see along dacron on the trailing edge all the repairs. Fabric started falling apart from just touching it. That's when I treated the sail and its now as good if not better than when it was new. Here is how.
Pump up and open the kite. Get a small can of water based clear acrylic varnish or sometimes called acrylic emulsion. Usually this is intended for waterproofing exterior concrete walls. Mix half and half with water and apply one coat on each side of the sail. A brush or a roller is ok, just try not to be to liberal to prevent beads but still apply sufficient for it to soak into the sail fabric. It dries quickly and withing 15-20 minutes the sail is like a new plastic sheet. Try not to get any on the leading edge to prevent soak through and sticking the bladder to it. Welcome to your brand new kite!
You should do some strength tests , to see if it actually is as strong as original.
Yes coat entire canopy if you want. Not really necessary on the dacron reinforced areas but its easy to do and makes it wind and water proof so why not.
It ads maybe about 100-200 grams which might be noticeable to a pro rider on a light wind kite but riding I cant tell the difference on any 12m or smaller kite.
You are welcome to do strength tests if you feel necessary. For me stretching it by hand was enough to know its more than good enough to ride. It becomes a reinforced plastic sheet. Windproof, waterproof and as close to original as you can get with a kite that was starting to fall apart almost by itself and was ready to be thrown into rubbish.
Keep in mind it works best after the original impregnation is gone as then the varnish soaks in completely into the canopy and no chance for peeling. That's why U should mix half / half with water. To help it soak in.
