Hovercraft Project

I had thought about sheet metal, but one of the things I've heard is that diverting the muffler from in front of the prop will decrease the noise. (Apparently, the prop magnifies the exhaust noise.) I had thought a pipe would do that better, I just hadn't figure out what to use and how to get the tight bend.

Never thought about amplifying the noise, I guess it would bounce off the prop every time it passes and would get scattered or concentrated in various ways.

A pipe would look more professional too, it is just the frugal bastard inside of me trying to save you a buck.

I wonder if somebody who does motorcycle mufflers could do something for you.

I took Zoama's advice and ordered a mandrel. I had talked to a local muffler shop, but I'd rather do it myself. It probably won't look as good - but it's another learning experience.

I'm just waiting for the mandrel to arrive. When I do it, I'll post do a project post thread for it.

I really need to get back to the craft to do repairs and adjustments, I've just been focusing on my CNC table build. But, the table is progressing well - so I will probably make time to work on it soon.
