I replaced a locking latch on a '70s-era Fender bass case I got for $40.
Luckily the local music store had a used latch just like the broken one. I had to drill out the rivets holding the latch in place and re-rivet the replacement piece. I don't remember how I peened over the rivet (been maybe 20+ years) but I still have the case and the latch is still in place.
Of course, I'm quite gentle with my instruments...but the latch doesn't have any load bearing on the rivets directly, so they don't have to be super robust.
I recently acquired an Epiphone Sheraton II with a hard case that had a broken clasp. In addition, the strap that keeps the lid from flopping all the way open was broken.
I've already repaired the strap. First I found a nylon web piece:then I pulled away the plush lining from around the ends, yanked the old staples out, and stapled in the new piece using an industrial-style stapler designed to staple into wood, as opposed to an office type that has an anvil to form the staple.
I ordered a new clasp from
www.stewmac.com and I hope to get it today (along with some mini-pots for the guitar -- it's getting Seymour Duncan humbuckers). I couldn't find a clasp with the same rivet spacing as the existing part so I'll have to drill out the rivets and drill new holes for the replacements.
I'll have to find rivets -- I saw some at the local Hobby Lobby where I bought the nylon strap, but wanted to wait until I had the clasp in hand so I'd get the right size.
Anyhow, it's not difficult, but it's easier when you have actual matching parts.
Thanks for the link: I appreciate knowing a source for all those little gubbinses.
