I think this is the one you are looking for.

Eddie Bernard had one of those things at GAS back in Corning I think. I had exactly the same reaction Eben. I don't know if there ever was demand. Try to imagine if you slipped on the pneumatic foot switch and the door closed on a fairly hot piece.

I like that they made sure that the first pic says ass beads in the background.

Ed Branson came up with the coolest gloryhokendoor I have seen in a long time as far as being able to close it down easily. He has a pneumatic lollipop door against his retaining ring that has a 2 inch opening. Then outside of that he has a set of barn doors. Genius.

That does sound like a clever GH door setup. Do you know if he tends to run it so that the lollipop door re-closes when he's not actively taking a heat? Or just leaving that door open once the piece has gotten bigger than 2 inches and only using the barn doors.

I'd worry about losing too much heat from having the barn doors a few inches from the retaining ring with that setup, but if the pneumatic door re-closes when you're at the bench, it addresses that problem nicely.

They seem to love the aperture/iris doors in Europe. Great idea, but lots of potential issues if something goes wrong.

Do European glass students manage to not dribble hot glass on every surface in the shop? That thing would probably last a week in the public/school shops I've worked in.

He closes the pneumatic door every time and leaves the barn doors open.

Outsmarting yourself is a constant issue in design.

Here's a video.
I didn't see how the doors were controlled.

I notice that he has to flip the piece 180 degrees every trip between bench and glory. And the bench looks like it folds up. Made of electrical conduit or something.
