As a fairly new bottlestopper turner after turning pens for 4-5 years I have a question about stainless steel stoppers. I have been using the short cone-shaped stoppers I heard about on here. I think they are very good and like the fact they are made of FDA approved stainless steel. I just heard from a fellow turner that someone told him/her that they "didn't fit any wine bottles he had". I'm wondering if this has been an issue with any of forum members. I figured with the 3 different sized o-rings that they are more or less universal. Please respond if you have experience with this. I'm no wine bottle or stopper expert and am just looking for more information on this matter. I'm sure there are people here who make lots of stoppers and can give some relative input on this. Thank you for any input.
