Hello
Newbie here
I did two infusions with this mould made with the starter kit, totally failed
The boxed shape corners were not completely pressed in by vacuum, I should have known that. Had too much epoxy in the corners and dry points..
I did try infu-tac, but gave up on it because I mainly messed up and and tore the fabric, messy stuff.. Should I glue the center first and move towards the corners with the glue, or glue in corners only?
Then should I get gelcoat along with infu-tac, as it would leave a cloudy finish? Should I use it post-production or spray in the mold, and does it then work like glue?
Or making my own epoxy tack spray. But am I likely to mess it up? 100:5 epoxy/hardener maybe
So many questions, more to come.
This a good setup for infusion? I used compoflex. Would normal infusion mesh and peel ply be better?
And I had troubles not getting a perfect vacuum. I could not find any leaks but air was getting in from somewhere. There is some damage on the mould caused by removing the pattern, and sanding too much. Think I need to check that the mould is not leaking too.
How should I proceed next time with the infusion. Carefully cutting the fabric in the corners and using glue with other layers also?
Thanks in advance
Ville

Thanks. I wonder why I was planning on using only a single piece, cutting separate pieces each side sounds a lot easier. And it will do a better job with my skills.
I have a roller and ec-cutter available. I'll try spray-tack before cutting. Top tip.
And I'll test if the mould holds vacuum with just bagging film, and no pleats. I'm looking to make a few pieces. It will be a batterybox for an ebike, eventually.
I got one part nicely out of the mould. But it was so bad I didn't take pictures of it yet, hehe.
