G'day JeZeBeL,

If it were mine, I would make up a fitted case from aluminium sheet: I knock up the main ring first, overlapping the ends and rivetting the seam with hammered aluminium rivets. I'd make the ring over height by some 25mm ... and turn under truncated "V"-shaped tabs to rivet on a circular base. This would all be made large enough to line with closed cell plastic foam - and that would be covered in some appropriate tough cloth and glued in.

The lid is just a repeat with less depth and a slightly larger diameter ... plus a suitable hinge and lock. I'd probably put two small wooden bars on the side to act as "feet" when it stood up sideways and I place a decent handle opposite. Since your drum doesn't have the usual Bodhran crossbar, I would not need to (or be able to) put in a frame to support the drum ... but it sounds big enough and ugly enough to look after itself in a simply padded box.

Regards,

Bob Bolton
