I think it was on this Forum but I can't find it....a Forum member was refitting a Gretsch snare (maybe a bass drum) badge and wanted to know the perfect grommet length to make the badge fit snug.
I'm going to be fitting a few Round Badges onto some three ply shells and I may have to use some grommets I bought new online. They seem to be a little long. I bought the tools - two - one to fit the snare grommet and the other the bass badge grommet.
What measurement do I use to make sure the tool will give the proper 'Roll-Over" inside the shell.....= allowing a snug fit?
