Anyone have a file to 3d print a cork barrel tool?

ryebrye · by **ryebrye** » 2024-01-24 9:32 a.m.

Maybe it'd be easier to just get some pipe and cut it out, but it seems like the tools you'd need to remove and replace cork barrel stuff would work if they were 3d printed.

Anyone try this yet or should I come up with something on my own?

The bumper removers like these ones:

The spacers would be easy to print something that'd work well too, I think:

Hey now... the 3d printer might just require me spend a couple of hours on a computer creating the file and then sending it to the printer and then printing it a couple of times until I got it just right - but getting actual pipe might require leaving my house, driving to a store, and then spending 5 minutes cutting it :lol:

(or... I could just pay $60 for a pair of them and still not need to leave my house... hmm....)

Actually, there are people who will bring pipe to you. Try McMaster-Carr, or Grindr.

The Ferree's is way too pretty. Find a small piece of typical 1/2" copper pipe and cut a burr into the end and curl it up. Mine works great. Then find a girl's "pony" and use that as bumper material. Then you'll never need your tool again.

When's the last time you paid for delivery of a little piece of anything from McMaster-Carr? :lol: :lol:

This may be seeming like a real "first-world" problem. But given the current price of copper, maybe the printing approach is actually economical. When are places like Staples going to have 3-D printers beside all their other stuff so you can just walk in with a file and walk out with with a printed product?

elmsandr · by **elmsandr** » 2024-01-24 12:47 p.m.

Probably when 3D printing works like that. Lots of “Spaghetti “ and tweaks seem to be the norm with printers now.

Heck, a tool like this will take a couple of hours on most printers.

Cheers,

Andy

Um... 2014?

Many of my local libraries also have 3d printers for public use.

But of course Andy is right...it still takes hours.

To actually help... if you want to make your own, just get some hobby shop K&S brass tube. 21/32" OD is perfect for bass/large tenor, and works on the majority of smaller stuff too; 19/32" if you want a dedicated small bore tool.

harrisonreed · by **harrisonreed** » 2024-01-24 1:17 p.m.

What are you gonna 3D print that thin tool with - ABS? I'm no master of 3D printing but for the tool to work and not break, it has to be pretty darn thin, and sturdy, especially on the business end.

I think the thinnest you can go is something around .4mm -- you're telling me that a .4mm thick little bent hook of plastic isn't going to break off in the cork barrel? That is, if that is thin enough to begin with.

Oh that's helpful - thanks. The ace hardware by me can ship-to-store a foot-long section of those for around $5 each.

If I'm going to cut replacement cork from a sheet like this video (which seems easier than trying to keep a stock of different sized cork rings for different diameter slides)

<YOUTUBE id="iG28EcNjgJM">https://www.youtube.com/watch?v=iG28EcNjgJM</YOUTUBE>

What thickness of cork should I get?

ithinknot · by **ithinknot** » 2024-01-24 2:45 p.m.

1/8" or 3mm usually does it. If necessary, you have quite a bit of leeway for compressing it in the rolling stage

This.

You definitely don't need (or want) pipe.

I think that reference is just to their selling of 3-D printers, so far as I can see. Their current list of "3D printing services" includes only two stores in NC -- both near Charlotte.

The local libraries here are lucky to have books -- which probably no one reads any longer.

Last time I looked, cork rings for trombone slides seemed easy enough to get on the web from, say J. L. Smith? But why not just use an O-ring, or cut your own felt ring bumper?

Also, you don't need the official cork tool. You can go to Harbor Freight and plunk down $5 for a set of 6 different "hook & pick" tools (basically dental picks, so you can also do your own tooth cleaning and dentistry). Very versatile for work on brass instruments as well.

Hmm, I didn't think about that. I actually already have a good plastic and brass pick and hook set that I use to work on scuba gear (remove o rings etc)

I'll try to make one of those tools anyway though because I already ordered the brass tubing to do it.

ghmerrill · by **ghmerrill** » 2024-01-24 6:07 p.m.

You can never have enough brass tubing.

Why not get trumpet felts? Very commonly used. If you don't want to bother with Allied or Ferree's, you can get them all over eBay, etc. Cork tends to break pretty quickly and you end up with a mess of cork pieces inside the cork barrel. The felts will stretch to fit over larger slide tubes. You don't need multiple sizes.<ATTACHMENT filename="felt.jpg" index="0">~~[attachment=0]~~felt.jpg</ATTACHMENT>

Why not get trombone slide bumper felts?

https://www.hickeys.com/search/products/sku077497.php

Sometimes in maintaining/repairing brass instruments we focus on getting "the correct replacement part". But with experience you learn that there are often perfectly acceptable alternatives -- and sometimes the alternative are actually better than the originals. Anyhow ... alternatives are available.

LOL, those are just Ferrees valve washers re-branded as "slide bumper felts". <LINK_TEXT text="https://www.ferreestoolsinc.com/product ... 6041&_ss=r">https://www.ferreestoolsinc.com/products/a99-felt-valve-washers?_pos=2&_sid=b121a6041&_ss=r</LINK_TEXT>

But yes those would be fine for the purpose, and would save you having to figure out what size to order.
