18W Nether Trencher

Design by @K1NG Based Off 12W Trencher by @DividedByZero @Shinji @Sg > Features : • Built in and-gate (18w) • Dupers clear terrain higher than core • Cart-less coral-less dupers • B-36 block breaking > How to use : • Fence gate is the on/off • Don't turn off while core is moving forward • It requires a 2x18 tunnel at the bottom that has to be manually dug before running it • Meant for nether world eaters with 15 wide or bigger trenches
