Bob's Big Bore Tunneler

Do you need to punch a 50-meter square hole vertically and/or horizontally so you have a place to park your ride in the shade? Your very big ride? Now you have it with Bob's Big Bore Tunneler, the latest development from those good 'ole boys at Spiff's Practical Engineered Solutions.

Bob's Big Bore Tunneler utilizes two separate cockpits to control vertical and horizontal tunneling coupled with Archon's AutoLevel script for stability:

Using numerous large atmospheric thrusters powered by four large reactors, tunneling is performed by 144 drills in a 12-by-12 array. A large number of gyroscopes controlled by the AutoLevel script minimizes lateral motion of the ship during the tunneling process.

NO MODS, NO DLC, NO ROTORS/PISTONS; SURVIVAL READY AND PROJECTOR BUILDABLE!

STATISTICS
 - Blocks: 3,127
 - PCUs: 37,696
 - Mass: 365 tons

CONTROLS
{1} Drills (ALWAYS RIGHT-CLICK TO CLEAR; NEVER LEFT-CLICK TO MINE OR THE DRILLS WILL FILL WITH STONE AND CAUSE A CRASH!!)
{2} Camera Center Down
{3} Camera Left Down
{4} Camera Right Down
{5} Camera Top Down
{6} Camera Bottom Down
{7} Run/Stop AutoLevel
{8} Programmable Block On/Off

BUILDING IN SURVIVAL WITH A PROJECTOR
Ensure sufficient vertical blocks are placed either below or above the projector to provide sufficent clearance for building the drills. The required parts are:
 - 10,556 Steel Plates
 - 284 Metal Grids
 - 54 Interior Plates
 - 5,979 Construction Components
 - 3,132 Motors
 - 875 Large Steel Tubes
 - 556 Computers
 - 12 Displays
 - 160 Bulletproof Glass
 - 380 Reactor Components

OPERATION
For both cases, either vertically-tunneling a shaft or horizontally-tunneling a drift, tap the direction key slowly (about once per second) to creep down/forward. Tapping the direction key too quickly can overcome the tunneler's inherent stability and cause it to tunnel in a skewed direction. To produce a larger shaft or drift, simply move the tunneler laterally or forward/back (or up/down if tunneling horizontally) by as much as 20 blocks.

A. VERTICALLY BORING A SHAFT
   1. Build a 21x21 block guide frame embedded into the planet's surface to be a tunneling guide; the tunneler will clear material almost to the outside edge of the guide (approximately 52-meter square opening). This guide frame will also serve as the structure for building an aligned structure on the walls of the shaft and deck at the bottom of the shaft.
   2. Align the tunneler over and within the 21x21 block frame's outline. Move the tunneler laterally, while using the top down {5} or bottom down {6} camera, to check that the tunneler is parallel with the guide frame. Once parallel, activate the programmable block (if it is off) with {8} and use {7} to engage the AutoLevel script; the color of the gyroscopes will turn from green to blue when AutoLevel is active (which is why I added a single gyroscope to be visible from the horizontal tunneling cockpit).
   3. Use all four down cameras, {3}, {4}, {5}, and {6}, to center the tunneler within the guide frame's periphery.
   4. Select the drills {1}, right-click to begin clearing, and use the down key to start descending into the ground.
   5. When the desired depth is achieved and no more tunneling is planned, disengage AutoLevel with {7} and deactivate the programmable block with {8}.

B. HORIZONTALLY BORING A DRIFT
   1. Build a line of guide blocks embedded into the planet's surface to be a tunneling alignment guide. This guide rail will also serve as the structure for building an aligned structure on the walls and ceiling of the drift and deck at the bottom of the drift.
   2. Align the tunneler over guide rail. Move the tunneler forward and back while using the center down {2} camera to check that the tunneler is parallel with the guide rail. Once parallel, activate the programmable block (if it is off) with {8} and use {7} to engage the AutoLevel script; the color of the gyroscopes will turn from green to blue when AutoLevel is active.
   3. Use the center down camera, {2}, to center the tunneler over the guide rail.
   4. Select the drills {1}, right-click to begin clearing, and use the forward key to start tunneling.
   5. When the desired tunnel depth is achieved and no more tunneling is planned, disengage AutoLevel with {7} and deactivate the programmable block with {8}.

An example for tunneling a very large, 150-meter wide by 100-meter high hangar into the side of a mountain is presented in the above pictures. The ship inside the hangar is one of my earliest "whisky" ships, Talisker by the Sea:
