I'm not having much luck with google today. Lee Valley's hardware catalog seems a dead end.
I could rig something up, surely, but it would be easiest to replace the original latches with similar parts. I have two old trumpets here with bad cases. One of the cases (from '48) is fugly, and I'm not worried about fixing it because I plan to build a new one. The other one (from '69) is in good enough shape to send the boy off to school with it (as long as no one in his class notices the gorgeous orange shag carpet lining it... ugh!), but the latches that keep it closed are broken. Well, one of them was broken. Now they've both been removed.
I mention the fact that there are two cases because by the look of it, the parts are of an identical form factor (slightly different locking mechanisms), even though the two trumpets are from different decades, and different manufacturers. It looks like the rounded brass-plated steel edge guards are identical too. These look like off-the-shelf parts from the age before high-impact plastic (though curiously, the '69 case has a styrofoam insert... did they have styrofoam in '69? I guess so... I ain't that old. Sorry all you geezers.)
Anyway, anybody got a clue here? The more stout half of this is 1/2 plywood with about a 2" long oval hole routed in it (with a 7/8" bit it looks like) to accept the locking part. The other end just has a little spring loaded flippy thing that engages with the locking bit, and the part where it attaches is only about 3/8" thick. Hard to describe, innit?
If I can't come up with something for this, I'll have to come up with a whole different plan. It's covered with mottled faux leather brown vinyl stuff. The wood is too thin to do anything creative with, but I'm thinking walnut might look OK against the vinyl. Maybe attach some kind of extra mounting pad and use some other kind of hardware on it.
In the latter case, any good ideas (with URLs, preferably) for some kind of non-OEM rig-something-up replacement hardware that would make for a good, very secure, spill-free closure of an instrument case? Preferably with some kind of locking mechanism. (My flute case was always flying open in middle school. I don't know how many times I dropped that thing on the stairs. It's no wonder I was 13th chair. I don't want the boy doing the same to his trumpet.)
And finally on this subject...
That one case is seriously, seriously fugly. I have a dent bag... Um... A gig bag I can use for the time being, but I want to build a new case for that horn. I started off with some plywood I have on hand, and by the time I cut out the parts, I had a 40 pound monstrosity. 3/4" oak ply with birch faces. (Why birch on the outside, oak on the inside? I'll never know.)
It's too heavy, and it's too light too. Oak wouldn't be much better. What Daddy really wants for his precious baby trumpet is something done up in walnut and brass. Oooooh, ahhhhh.
I could use some joinery ideas. I'll never find boards wide enough, so I figure start by gluing up 3" wide strips or such. Then I have six pieces to make a box, more or less, but beyond that I'm not quite sure what to do.
I could actually use a plan, I think. I don't want to get too fancy (no dovetails or anything) but I want it strong and well-built.
I have a long time to think this one over, since I have a walnut budget of $0 at the moment. Any nifty ideas?
What about hardwaring it up? One thought I have is to do simple double rabbet or whatever joinery (two interlocked L shapes) and hide the end grain under brass angles running between brass corner plates. Dremel up the brass and make it spiff, then cover the whole thing in... well, probably poly I guess. (Yes Monsieur Jacques, I'm thinking about polying walnut, because poly is indestructible, and this thing might see some nasty substances spilled on it.)
That could look seriously cool if I pulled it off right. I want people to go "holy crap dude, that's an instrument case? why? why on earth do you have such a gorgeous, ridiculously ornate and spiffy looking thing as an instrument case?"
Blah blah blah. Thanks for listening.
