I found a very informative webpage which discusses in detail about building a bottle tumbler and shows some outstanding pictures of step by step use. http://www.privydigger.com/cleaning.htm
well folks, thanx to your input and guidance, i've got my homemade tumbler doing it's thing. i ran a couple " junkers " through and have had mixed results. asked a few more questions and now seem to have the process dialed in much better. a few days and i should have some before/after pix. ( got my fingers crossed anyway ). thanx again for everyones help.
after about 4 days or so. glass was very sick on this one so probably could use at least that much time again to clean it up nice. very pleased though......... i'm learning.
i ran this one for a couple days to buff it up a bit. what a difference!! cleaned up all the haze from the inside and removed the old paint that was on the embossing. gotta say the bottle seemed to turn from a regular ho hum amber into a sort of reddish amber after polishing. i'm getting the hang of it.......sorta..............
