I just bought a rolling cart for our songsal machine on Amazon, as well as last night when I used it it was particularly loud in the streets, so I need to find some kind of solution to quiet the wheels down a little bit. I am thinking that I can take a tube from a bike as well as split it in small strips as well as glue it with epoxy onto the surface of the wheels so that it is quieter. I believe the local corporation near me will have something that I can use to make it quieter. I am an HVAC machine engineer as well as I should be able to figure this out instead of returning the thing, which I don’t care about to do because it’s just a waste of time as well as money for everybody. I used to build heating as well as cooling equipment, as I was a process engineer as well as had to figure out solutions to all kinds of things, so this should be a really easy fix. I just don’t want to bother the whole city when I am carting back our songsal machine at night from our gigs that I am doing around town, however last night there was somebody running a small portable a/c, you think those window units that stick out of the windows, as well as when I was going by with our cart I could not even hear the a/c running because our car was so loud. I do a lot of gigs, so I am always going to be using this cart as well as I don’t want to bother the city every time I am going down the streets.
