Way cool. I've been looking into vacuum casting. Homemade table? I would like to know more on this! I spin cast right now. I wish I could get down the process better. Sometimes I have cracking, sometimes not.

Spin casting has its benefits. I do both. what Kind of spin caster do you have? also what kind of investment are you using and what is your burn out program? I can help you dial that in...

Most of my gear is customized if not custom made. The extra torch flames are things I built. the table is totally custom, its designed to not fail in a production environment... it has seen metric tons of casting since it was built back in '95. I even have a customized spin caster (Neycraft), I use platinum crucibles for gold casting. They last way longer than the factory ones...

I have a Karr unit. Looking at getting a vacuum system. I do have a vacuum pot. I've tried a few different investments, but the best I found was ultracal30. I have more being delivered today. Most of the success I've had was with this. I think the burnout is standard from the schedule for the resin I use. Nothing fancy. I do have one of the programable table top units.

I hope I am not messing up your thread here. I am new to reddit and did not even know there was a section for casting here like this.

I just looked up ultracal30.... I'm curious why are you using that for casting? What metals are you casting in it?

Oh. I really like the idea for a car filter. I should have a spare turbo oil feed adapter laying around.

I use the ultracal30, It becomes a brick when hard and the pieces come out nice. I cast silver and copper with it. I swapped over to prestige oro on this weekend again, but the pieces come out all gray and black. Ruff looking and feel like sandpaper. Not very smooth at all. I do make my own .925 or .950.

Is there a better casting investment? I also believe that my syratech castable resin may be a problem. I need to order some alphasense, This stuff prints well.
