I restored a 68 Rogers BOP kit with orphan shells. a 18' x 16" TF converted to 14"x18" bass drum, a 12x8 and 15x13 FT
Everything went great till the final step 18" Maple Hoops.
Purchased a set Maple, 1.5 tall 12 ply from a reputed place. Hoops were unfinished so I cut the 1/2 slot for the inlays and painted black. When I mounted on the BD to my horror they were too big to the point that some of the claws would not slide in the hoop becasue pushed back too much.
Contacted supplier and they asked me if the Drum head was for a FT or for a BD.
To me it makes no sense. for an 18" BD the inside Diam of the hoop should be 18 1/4" or be flush with the outer edge of a drum head. ( using REMO as a standard Head) If the hoop diam is bigger than the drum head the hoop is too big. I wished i had try them on before all that work, at least I could have returned them, now instead i have to eat them unless i can figure a way to make them smaller. Any input? what the I.D. of an 18" hoop should be. I will post some picture when i get home.
