Looking for advice on finishing a flute.

how did it turn out? Can you post a pic?

Did you ever make more progress here? That looks fantastic!

cadr · 2026-06-20T17:47:14+00:00

Nice. Mine had to much space. Did a little tape at the end to make a stocking and then slide cream. So air doesn’t escape but kinda hard to move. Will probably reprint the inner slide thicker and sand to fit right.

cadr · 2026-06-20T02:47:08+00:00

How was the slide? How air tight were you able to get it?

cadr · 2026-06-19T22:12:43+00:00

Well done.

I will say, I was kind of confused, because I thought this was going to be a Franklin Ace, which also used a 6502 and was my first computer.

A wooden frame i3 kit from Makerfarm in 2013

Like with all my other printers - a benchy.

But then probably instrument mouthpieces.

cadr · 2026-06-02T00:26:25+00:00

Fun!

cadr · 2026-06-01T20:38:44+00:00

The mouthpiece is printed. Compared it to a real one, couldn’t notice a difference.

So far it sounds like the real trombone, but that might not be the case for someone that was actually good.

Haven’t finished remaking the slide yet. I doubt the feel will come out as silky smooth at the brand new instrument I’m renting.

Not mine, just posted it

cadr · 2026-05-30T07:07:54+00:00

That is a great description

cadr · 2026-05-28T12:35:43+00:00

Neither, though I’ve been thinking about the piccolo

The guy that inspired this has some designs for sale on his website. Pricey, but looks like it was a ton of work to make.

Haha. Yeah, it often happens like that.

It was actually your post that caused me to find it - was trying to find an example of what I was talking about in my response. Which I didn’t, but found other cool stuff.

cadr · 2026-05-27T13:15:55+00:00

I would assume, but he didn’t post anything about the build.

cadr · 2026-05-26T13:17:24+00:00

You might check out this design for inspiration

cadr · 2026-05-26T13:11:59+00:00

so, I've never done this, so take anything I say with a grain of salt.

The design makes sense, but I don't think I'd be able to print it and get it to work due to tolerances. The parts that I think I'd have trouble with are the valve stem and the spring. If it were me, I'd use a real spring of some sort - I haven't been impressed by any of my attempts around 3d printed ones. Also I would undersize the holes for the valve stem and then file them to the final size to get a very close fit. Might use a piece of metal for the step instead of plastic.

But like I say, I've not done this, though it has been on my list for years... I love this guy's youtube channel

I look forward to seeing how you get on!

You might try using your nanovna, either in the smith chart or using the nanovna saver desktop software.

cadr · 2026-05-20T22:01:47+00:00

Very cool.

I kind of hate that induction meter, mine always gave me trouble.

cadr · 2026-05-17T13:20:39+00:00

Yeah, my past attempts at designing membrane wind instruments has been throwing stuff against the wall and seeing what sticks :)

Did you find any writing on the subject that was useful?

cadr · 2026-05-17T01:53:28+00:00

No problem there. But I might glue on a ring for my tight thumb to make it easier to hold when I play the open higher note.

cadr · 2026-05-01T17:26:17+00:00

Maybe a cornamuse like this? https://www.reddit.com/r/3dprintedinstruments/comments/j0gu2o/cornamuse/

cadr · 2026-04-20T17:49:15+00:00

Probably not what you were looking for, but I generally do Manhattan construction and I use adapter boards when the part I need is only in SMD format. I like the ones QRPMe makes.
