What type of tape do your use? Where do you put the tape on the bottle (on the pontil directly, just on the bottom of bottle, not touching the iron, etc?Been tumbling bottles for a long time. I usually tape the pontil and thats it. DONT overthink it. Pontils are very tough. I did one and forgot to cover it and nothing happened it looked fine.
I used to tumble my bottles, my friends, and even other collectors whom I didn't even know. Had a really bad seizure and lost most of memory about 10 years ago. I do remember tumbling a pontiled Fields, just was running a cutting grit on the inside, taped the lip so no grit would get out to the outside of the bottle. I lost half of the iron on the bottle, no cutting grit came out of the inside. I have quite a few bottles that need tumbling from before I had my seizure.
Thanks for your post and would appreciate any tips on tumbling.
