I've got a TIG man who can weld potmetal on 'most' bodies (some are so high in zinc, they explode.) Then carving ears back to shape is my job.
The Threadfix for bowlstems in an insert/excert that is installed after shaving the old threads with a piloted Manley valveguide cutter. It is is removeable for nozzle service, and won't turn to cheese like potmetal.
And I guess that means there are four different floatvalves,.... at least! The early 'glandnut'levers and valveneedles that will work in "shortbowls" are available from http://www.indianpartseurope.com/
, but longbowl levers are still a dream.
'Script' knobs, are in the works as well,.. more or less....
I'll have a customer post you about a potmetal shortbowl, thanks!
