Custom Size Graphite Tree Jigs

[gomilobster]

I think mountain glass even has a warning on their page about the aluminum HA holders... kinda still trying to figure out why they used that metal compared to all the other metals they could have chosen, but I guess scientific workers are precise little goblins if anything, A brass holder would be pretty sweet, do you have GL-18 or 14 as well?. Griffin Glass has a graphite holders in 18 and 25, but its a bit of loot for something I can only imagine would quickly wear out given then nature of a thread and graphite.

Sometimes the caps for the GL threads look annoyingly large (depending on the vessel/vial/bottle you want to make I guess) as I seem to have seen some on smaller vial/bottles and the cap diameter look huge and kinda ugly, I can only think this is in large part due to the size of the thread. Some smaller caps/holders would rock for those smaller tincture vials.
