Is there a launcher that can release 1 Main rocket with 3 boosters simultaniously, But made with widely produced parts that are NOT custom made on a lathe?

im not sure you can buy a launcher like this, but these launchers are quite simple. only the centre bottle needs to be held down because the centre bottle holds the the boosters down, which also ensures that all boosters fire at the same time. lathed item are a luxury and not needed to make this. just use the same matrials that you would with a normal launcher.
