Hi and welcome Hi

I split your post out of the Euphonium thread since it has nothing to do with the original topic.  Please don't be embarrassed to start a new topic for a new question.

We have discussed PVC trombones before.  Here are a couple of threads to read:

http://tromboneforum.org/index.php/topic,35189.0.html
http://tromboneforum.org/index.php/topic,34894.0.html
http://tromboneforum.org/index.php/topic,32267.0.html

I don't think we have discussed this much recently, but there are older threads here with nice pictures and everything.

Good luck.

I see someone already linked to the trombone i had once made as a gift. I see my pictures are offline... It still works, although the owner now has bought a proper brass trombone :)

But it's really not that hard to put together. Measure a real trombone to get the right size. You can buy two sizes of PVC tubing, which fit nicely for a slide. Be sure to buy the right PVC glue, or it will not be airtight. Be sure to make it airtight. Test by holding it in water at all the joints. It will not sound good if you have a leak.

Some sort of a bell - or a funnel - at the end looks nice and makes the trombone sounds much better and louder, but it will also make it horribly out of tune.

The part that took the longest was creating bracing. With some patience, it's very possible. When we built one, we completed it in a full day, including the shopping.

Oh, and we actually made it with a separable bell and slide section. Avoiding this is easier :)

Thanks BucTrom!

Yes, I have made a "contrabass PVC trombone" for a school physics project last year. It used a tuba mouthpiece and we traced its tuning to a loooww G-flat. I'll post pictures sometime in the next 24 hours. It cost me $40 to make, 3 hours to build, and a helluva lotta glue to hold it together.

I'm working on a similar project for my Adv Physics class.

Except me and my dad are working with copper tubing instead of PVC. =P PVC was going to be our second choice if the copper didn't work out.

Big problem with copper tubing (such as you'd buy from a Lumber Yard) will be getting it straight enough to work as a slide.

PVC has this problem too, but seems to be more compliant.

A much simpler musical instrument project is to build a natural trumpet or Waldhorn since they don't use slides or valves.

Good luck with your projects.

Just about all the PVC (polyvinyl chloride) trombones have been home-made.  It's a challenge, but can be done.  There was a guy who made outer slide tubes from carbon-graphite but I think he's passed on so they aren't available either.

A nice simple project to get you started in homemade instruments is the Hosaphone (TM).  Go to their Web site: http://hosaphone.com/  Make yours from 1/2" (12 mm) diameter hose and make it either 9 feet (about 2.7 meters) or 12 feet (about 3.6 meters) long -- pitched in Trombone Bb or F.

Just remember as you embark on these projects, you are working with materials with rather sloppy tolerances and you are not Steve Shires, so don't expect it to play very well.

Well, I do consider the extremely bad intonation a small problem also. :D
