GROUND GLASS JOINT HOLDER - 19mm FEMALE for LATHE WORK by FLUG

19 mm Female GonG holder for lathe work.
Graphite is fine grain which is sturdy and will stand up to lathe work.

True-Running portion of the shank is 5/8" x 3" 303. The tail is 3/8" x 2.5" heavy walled 304 tubing and probably won't run "super" nasa true. The shank is bored out of bar stock and turned and faced as it's extremely hard to find true running, actually turned, round steel tubing.

Shank is threaded 1/2"-20, graphite is threaded same and cemented to the shank with a sodium silicate+refractory cement. This will take a great deal of heat (~2200F) but, like anything in high heat, isn't totally invincible.

Graphite is turned on the shank so it runs true with the shank. If the graphite is removed and not indexed when it's replaced, it might not run true, so taking the head of is a NO-NO!

These have a thick lathe shank but they're not meant to be beaten on. Please use your knowledge of thermal expansion etc. to make sure your not clamping glass on/in the tapers.
