I'm not anywhere close to a pen master so I'm really not sure. All I do is turn and finish regular wood blanks. I don't even have alot of experience with acrylics.

Try casting one and turning it.If there's one thing I've learned tonight is I've got no computer skills.![]()
EKG paper is generally thermal (At least it was the last time I had one) so if the resin process or the turning generates a lot of heat it'll possibly turn black. I played a little myself with the laser and I could laser it onto a lighter blank or even a blank dyed pink....... But I don't know how I'd get the grid.
do inkjet on labels over painted tubes with the barry gross casting kit. i think 27/64 tubes or bigger the bigger sierras probably will look the best.
