Hash Fellow robcat2075 Posted August 12, 2017 Hash Fellow Posted August 12, 2017 Over on the trombone forum someone was lamenting that you can't have a slide trombone with a conical bore from one end to the other. 1 Quote
*A:M User* Roger Posted August 13, 2017 *A:M User* Posted August 13, 2017 That seems like that would be impossible to do without some very expensive engineering, or materials that we don't currently have. Also....there are trombone forums? Quote
Hash Fellow robcat2075 Posted August 13, 2017 Author Hash Fellow Posted August 13, 2017 That seems like that would be impossible to do without some very expensive engineering, or materials that we don't currently have. Very impossible. A truly conical bore instrument that you can also change the length to change the pitch is pretty much a geometric impossibility. Like having a triangle that also has two parallel sides. Also....there are trombone forums? It's remarkable how much discussion there is over there when the trombone hasn't changed much in 400 years.

johnl3d Posted August 14, 2017 Posted August 14, 2017 Requires a whole new lesson on slide position .... I played a regular one in High School Quote
Admin Rodney Posted August 14, 2017 Admin Posted August 14, 2017 Robert, you are on to something there. I shall now go and up my investment in rare earth metals. Nice demo BTW. That's what is so great about 3D software. It's great for showing off things both real and imagined. Quote
Hash Fellow robcat2075 Posted August 14, 2017 Author Hash Fellow Posted August 14, 2017 So, over on the trombone forum I also say that having a conical trombone is possible like having a triangle with parallel sides is possible, and someone helpfully points out that in some non-plane geometry it is possible.Fine, I say, all you have to do is get to the universe where that works on a trombone.It's probably the universe where Spock has a mullet, I say, thinking there is no such thing. And then someone comes up with this... Quote
*A:M User* Roger Posted August 14, 2017 *A:M User* Posted August 14, 2017 Yep, that's something I will never un-see LOL. Quote
Admin Rodney Posted August 15, 2017 Admin Posted August 15, 2017 Looks like Walt Disney may have caught a glimpse of that other universe back in '29 as recorded in 'Mickey's Follies'. The Elastobone universe... not the Spockmullet universe that is. Wow. Sorry for the huge gif. Let me see if I can shrink it. Hmmm... got it from 12.5MB down to 6MB with a few tweaks... more testing required. Edit: Looks like 5.7MB is the best for the moment without losing too much quality. Quote

That's great! I guess some stagehand was ready to throw him that trombone when he needed it. Quote
