Any sources for 32 and 52 oz bases and decorative toppers?

[Al Chemysto]

I'm ready to stat making some custom lamps and have lava lite glass and will also be buying a bottle capper.

However, what I don't have is a surplus of bases and toppers to make the the lamps complete. Anyone have any suggestions or even substitutes?

Ebay often has bases/toppers of various kinds.  An add in craig's list worked great for me here-I posted it under the "wanted" section.  Upside-down shotglass or something similar works w/some styles. I use a hose clamp to re-seal my globes-jus position your cap, fit the clamp on, tighten the screw, maybe loosen screw/reposition/retighten a few times to get even pressure everywhere, and then remove the clamp.  I tighten till I really can't turn the screw anymore...works great!  Good luck-
