    I'm using the new 3" chuck right now to machine a slug for a
veterinary syringe . I bought several at a yard sale with the idea of
using them as oilers . The oil turned the barrel seals to goo so I'm
machining an aluminum slug with an o-ring to replace the goo . Actually
it'll have two , one to seal the plunger shaft and one for the barrel .

-----------------
The type with a narrow-edged plastic piston that slightly expands the bore where it contacts seems OK with petroleum products like grease.
Hydraulic seals are made of Buna-N or nitrile rubber. Viton should also work.
-----------------
   These are glass tube assemblies with gaskets . I have some HDPE I could make a piston from but I'd have to have 2 thin edges so it would be able to suck oil up into the syringe . I think I'll stick with the o-ring design . I have metric and SAE assortments - I'd have to go out to the shop to see what they're made of and that ain't happenin' tonight .
   This morning I pulled the bed off my truck so I could do some finish-up work on the exhaust (finish some welding and fab/install a crossover pipe) and so I can remove the axle to take to the shop . I have a guy that's done gear set replacements that's going to do mine . He got a bunch of Sioux valve/guide/seat tooling in exchange for the axle work . It's going in as a 2.73:1 regular differential . It's coming home with 3.42's and an Eaton style posi locker .
   And my back hurts . After 4 shots of 99 proof whiskey it still hurts but now I don't care .
