I found it, this is the mask I have:
3M Powerflow Face-Mounted Powered Air Purifying Respirator (PAPR), Respiratory Protection 6900PF, NiCd Rechargeable Battery, Large Size: Papr Safety Respirators: Amazon.com: Industrial & Scientific
that battery is one heavy sucker and the wire from the battery to the mask gets caught and pulled on everything when working in tight quarters...
I haven't really worn it because I didn't think I needed to, I really designed my polishing system to contain these vapors, ideally they shouldn't be escaping in the first place. it does work fairly well, but not to the point of 100% containment
It would seem every time you add a process to your
devices, its like reinventing the wheel all over again!! You do have a great looking
device though...
it's my own fault really. if I had just been happy with the machined ultem look that every other vape manufacturer out there settles for then I wouldn't have had to go through this whole heat treatment annealing and vapor polishing developing and learning curve, but when I research Ultem and see what the medical industry does with this stuff I just couldn't help myself, it really takes the ultem up to a whole other level
check out this DNA sequencing manifold:
or this 2 piece ultem semiconductor manifold:
and here are a few other manifolds:
compare that to the frosted look that ultem vape devices have, I don't know about you guys but these images from the medical industry just really turned me on and I said to myself I have GOT to do that to MY ultem
even the hobo ultem mod was highly polished on the outside, yeah, but the inside was still frosted and you can't really see through it, just cloudy inside
you can't even see the green DNA chip that's right there behind the faceplate:
compared to this:
in hand and in person it's a huge difference...
