I think it is pretty impressive for a first attempt. Allen

My First Attempt at Casting

Looks good to me, ambitious for a first attempt.
Keep at it Vic I am not the one to give any advice as you know I have only just started myself. Luckily I have been fortunate that the blanks I made with out a pot have come out with no apparent bubbles, I am using Polyester resin.
I won't be using the Pressure Pot with the Alumilite Reson any more Derek. Just mixing and poring steady left very few bubbles and over a very short period of time I popped these with a tooth pick

Great effort Vic and a very good first attempt at a watch parts pen. The reason for using pressure for the Alumilite is the setting time is quite fast, the bubbles don't get a chance to float to the top of the mold. Pressure doesn't get rid of the bubbles, it just makes them smaller so you can't see them. pressure pots are better for tubless blanks.
Some people who use "Epoxy resin" tend to use vacuum to get rid of the bubbles as it has a slower setting time. I use Easycast water clear epoxy and put the two bottles of resin and activator in a bowl of hot water first. This increases the viscosity of the resin and gives the bubbles a much better chance of floating to the top of the mold. With this method I don't need a vacuum pot. Also when painting the tubes I use emulsion or black board paint as CA glue does not react with water based paints when dry. Hope this helps.

Interesting looking pen blank.
I use Resin Saver molds in a pressure tank at 45 PSI with no issues.
I plug the brass tube with Play-Doh which eliminates any air trapped in the tube and will not allow any resin to get into the tube while under pressure.
Works great for me.

I like that first attempt Vic I cast 2 pens with business card type labels and they were ok ish.
I hope to do feathers and watch parts soon, and Paulm has sent some mini pine cones so I expect to be quite busy.
I hope my watch parts try matches yours, I would be very happy with that.

Typecasting, I think, Vic
Sorry I haven't posted on here it's been a mad few days. It's a cracking effort Vic and I hope this lot haven't knocked the wind out of your sails too much. I love the imagination you've shown not to mention the techniques of which I know nothing about. See you've got loads of useful info on here now, top work!
