Well, my studio is all set up (and leaking around the window frames, argh) AND I got my second concentrator today! Then I immediately threw my back out trying to get it out of the box, LOL! Now I can sport a flame that will melt boro, ad I can hardly wait to work on it! I've spent part of the week learning how to plumb gas... got pretty far, and now I feel confident about plumbing a line to my studio for the torch.
For those considering a second concentrator for boro, there is a little plastic "T" that you can get at Home Depot for about $2, that connects that clear plastic tubing. That's all I used to hook up my two.
I made a bunch of beads two days ago, a few today, and I *might* get a chance to make some tomorrow... wooo!
Good thing I still had some Vicodin left... maybe my back will heal by the time it wears off.
