Got most of my 2060cfm glassblowing ventilation built today (going to set-up a boolit-casting station, too). Just need to put a side wall on the hood, some tile on the bench, and maybe get a little electric work done and I'm back to making calls.

Double action hood - great idea.

Most of that was greek to me but I do look forward to the end results. :eyebrow:
