Hi All, I recently purchased a secondhand set of Tama starclassic birch/bubinga drums. I bought new heads for all the drums as the old ones were not in good nick. In the process of fitting the new heads I checked all the bearing edges and hoops. All OK except one of the diecast hoops on the 12" tom was very slightly warped. I measured the gap with a feeler gauge ( I used to be a mechanical fitter) and it was . 03" , or .76mm at its widest point. ( I used a marble slab)The drum tunes up OK with no different effort required with any of the lugs. My sense is it does not seem to have any adverse effect on the tuning etc so not to worry about it, but its been nagging at me a little bit. Should I get a new hoop? What would you folk do?
