I have posted this info before, but I am putting together an orphan black and gold duco slingerland radio king drum kit, and I have two tom shells, a 9 x 13 and a 12 x 14. They both take the streamline lugs and have tack on bottom heads. The 9 x 13 has its bottom head in tact, but it is pretty slack, and the 12 x 14 is missing its head. I have a larger calf skin head that I could cut down to make a bottom for the 14, but how do I install and tension it? Or should I buy one to install? Where can I get a replacement tack on head? How do I add tension to the head already on the 13? Any help would be appreciated!
