I have been thinking about doing this conversion for several years. I bought the set in '71 and the number of times I've been on a stage big enough to use this floor tom have been few. I'd guess I've actually used the drum 1/2 a dozen times. A couple of weeks about I saw a post in the Ebay thread with some pictures of a converted 18" floor tom. I liked what I saw, followed through and completed the conversion in one weekend. Last night I played the set at a blues rehearsal and was super pleased with how the drum sounded as a bass. Many thanks to bizrad for the ideas he showed me.
