Hi all,
Just wondering who has had experience with coffee bean casting into pen blanks? and if there are any gotcha's to look out for. I read a post from dai sensei saying that some of the beans shrunk, anyone else had the problem?
I tried beans in PVC pipe with polyester resin and overnight in the pressure pot but it turned out crap, full of bubbles that couldn't escape around the beans and the resin was quite viscous.
Also how do you get all the air out from around the coffee beans? I've got a pressure pot and a vacuum chamber plus cactus juice and polyester resin but i reckon the polyester resin will set up before i can get the bubbles out.
my sister's partner has his 21st birthday coming up and he is a barista and loves his coffee so i figured a coffee bean pen would be a good fit.
Cheers,
James
