aside from the foot itself, you will have to learn to use and control your glazes so you can get them close to the edge without them flowing past - test test test


In Topic: Stuck T.s. Wheel Head!

Yesterday, 06:45 PM

same exact problem in all the HS classrooms i've visited that use the TS-style wheels...also likely why they all get left so dirty after use.

 

i simply used a small piece of 2x4 (rubber mallet would be a wiser tool of choice!) and gave the wheel head a few solid (but not beating) whacks at an angle, close to the center where the pin's fused.  usually it's enough to break loose the corroded connection, which the grease/anti-sieze was long-gone from.  maintenance maintenance maintenance!  i did notice on some of the really stuck wheel heads, that the aluminum head itself was slightly worn in the "notch area" which increased the problem - maybe a bad casting or just too much abuse from day to day use w/o servicing?  definitely use anti-sieze and not regular grease on this connection.

 

i've never fully understood the pottery wheels with removable heads vs one with a removable splash pan.  i'd guess that 8/10 that i've ever used have some sort of slight wobble that i always associated with the removable wheel head design.

"stick-up slip" is your best bet when trying to attach clay that's gotten to leather-hard.  it's a more advanced version of the modified slips mentioned above.

i like PC brand -- PC-7 and PC-11 are my go-to paste epoxies.  very similar to JB Weld.

they also make syringe-style epoxies that have great specs on paper, but i have no personal experience with those since they don't stock them on the shelf where i buy my regular PC-7


In Topic: Underglazes Flaking Off

if you want to attempt it again with this piece, i'd try sanding down the area slightly with a dremel tool to remove the outer layer of clay that's causing the issue.  if that doesn't work, i'm out of ideas.

 

on a side note, fingernail polish looks pretty darn close to glaze when you need a touch up :)
