"to do the Slingerland grommets properly you have to buy the $65.00 tool."
I sure wish somebody had explained that to me as I tried to install one from Chicago Drum today and it turned to crap. I used the flared screw method that so many have said works (yes, I searched and found a lot of "mis"information before proceeding). But...I guess the Chicago Drum grommets are thicker than most. The tool I made is exactly like the Jammin' Sams tool and was sized perfectly. It cannot turn the raw end of the ferule inward, making it rounded as in factory assembly. Mine split and just flared out as one might expect. Perhaps the ferule was too long, but this is what was highly recommended to me as correct 3 ply size.
Who is selling a tool that works for these at best price. MyOldKentuckyDrums doesn't seem to exist, Precision Drum links are not working. I can upload pics of how it turned out tomorrow if necessary. Pic is from Jammin' Sams sight.
