Big Buddha Measurements
Both stock tanks are slightly elliptical. I've tried to determine both minimum and maximum diameters in my measurements.
Serial Number 6660:
Glass tank ID: 25.2mm - 25.4, OD: 29.3mm - 29.5, Thickness: 1.95mm - 2.25, Height: 34mm
Diameter of groove where O-rings sit in top and bottom cap: 22.95mm
Diameter with O-rings installed: 25.5mm
Serial Number 0371:
Glass tank ID: 26.51mm - 26.72, OD: 29.55 - 29.65, Thickness: 1.50mm - 1.60mm, Height: 34mm
Diameter of groove where O-rings sit in top and bottom cap: 24.36mm
Diameter with O-rings installed: 26.85mm
Just for the heck of it, I bought some of these glass jars and chopped one of them down to 34mm using a rotary diamond saw blade:
10pcs Test tube glass bottle Cork Vial Pyrex 25ml 30*60*27mm
They're just a tad too loose on the old-style Big Buddhas. Here are the dimensions of those:
Jar ID: 27.29mm - 27.31, OD: 29.89 - 29.91, Thickness: 1.32mm - 1.33mm
The uniformity on these is better, but the walls are just a little thinner. A slightly larger O-Ring would be perfect. I may try to source one.
