sweet. they do have pretty good customer service. esspecially if they are going to take back the ones you cut up. did you check your recipt and order the correct parts but shipped you the wrong ones?
please let me know how the glass from mcmaster carr works out with the new TAs . i was going to order from them the same boro disks but wasnt real sure on the size. thi has been holding me up for moving on with my build. btw if you know some one with a lathe, have them face off where the glass is going to meet the copper. i did this to create a smoother surface between the copper and glass . also allows more contact area.
how do you plan on sealing the glass? im thinking about just wrapping the glass in PTFE tape.
Yup I ordered the correct ones and they shipped the wrong ones, and stupid me not realizing they were the cast ones until you pointed that out. THANKS! Wish that I had noticed before taking the time to machine them.
As far as the glass, 1-3/4" diameter, 3/16" thick was a perfect fit on the cast adapters, hopefully they will also fit the pure copper ones. And +1 on facing them. I've been playing around with the lathe at work and managed to turn some true and round disks for my condensers and plates
PTFE tape for sealing the glass, I've had great results with that on espresso machines, and trims up nice with a sharp knife.
