Building Bombs

Bombs are built by hand on a workbench in the world. The camera comes down over the bench, parts come out of the kit bag and are put down on it as real props, and every job needs its tool. A bomb built this way is handed over as an sd_bomb item that carries its build - planted, that bomb is the one that gets defused.

Workbenches

A workbench can come from four places:

Source	How
Admin panel	The Benches tab: place a bench with the placement tool, kitted out with the tools you pick
Command	/bomb_bench stands one in front of you; /bomb_bench remove takes the nearest away
Config	Fixed benches for your map in Items.Builder.Bench.Locations
Item	Players use the sd_workbench item to set up their own - see The Workbench Item

What is put down on a bench stays on it - for everyone, across restarts. A half-built bomb waits for whoever comes back to it; tools hung on the pegboard stay there for the next builder. The bench's lamp and shelf radio stay as they were left too.

With Required = true (the default), a casing kit can only be opened at a bench.

At the Bench

Walk up to a bench with a casing kit and use it (ox_target, or [E]). The camera comes down over the bench top.

Key	What it does
Q	Open and close the kit bag - drag parts, tools, and supplies out of it onto the bench
T	The tools on the pegboard - click one to take it down
G	Look under the bench - the storage shelf
H	Up to the shelf radio
B	The handbook on its lectern (A / D turn the pages)
V	Inspect the case up close
R / F / U	Turn the case round / flip it / stand it up
L	The lamp on and off - the mouse wheel over its shade dims it
X	Guides on and off
Enter	The work order's main button
Esc	Back out
Right-click	Hang the tool in your hand back up

The work order on its clipboard tracks the build - which step it is on, the firing plan, and the sign-off.

Bomb Sizes

Size	Kit item	Front bays	Explosive	Edge fittings
Small - Wren	sd_bomb_kit_small	2 (one is the timer)	1 block	3
Medium - Kestrel	sd_bomb_kit_medium	4	2 blocks	4
Large - Osprey	sd_bomb_kit_large	6	4 blocks	5
Extra Large - HIC-4410	sd_bomb_kit	12, front and back (one is the timer)	up to 6 blocks	5

The blocks of explosive packed into a bomb are its yield - how hard it hits and which hole it blows in a wall. See Bombs and Walls.

The Build

Every kit arrives taped shut in its carton. A full Extra Large build:

1. Open the carton - slit its three tape seams with the utility knife, fold the flaps back
2. Unpack - take the charge brackets and edge fittings out of the packing insert, lift the insert out, then lift the case out
3. Open the case - undo the front's four corner bolts with the hex key and set the front in its stand
4. Pack the charges - drop a charge bracket into each cell and screw it down, lay a block of plastic explosive in it, then put a retaining strap over it and pump it tight with the band tensioner
5. Wire the charges - crimp a detonator cap into each block with the pliers, then run its lead to the terminal of its colour on the firing unit and clamp it. Leads are cut to length with the side cutters and stripped with the wire strippers from the wire spool kit on the rack
6. Close the case - put the front back and do its bolts up
7. Fit the modules - screw each module into a bay with the cordless driver or screwdriver (screws come from the box of screws, tipped out onto the bench), then wire it in with the wire strippers and run its lead along the gutters to the timer's hub
8. Test the circuit with the multimeter
9. Fit the edgework - clip the serial plate, batteries, indicators, and port plates into the case's edges. The edgework is what the Defuser's rules read
10. Sign the work order off - the bomb is assembled and handed over as an sd_bomb item

The compact cases (Wren, Kestrel, Osprey) skip the heavy wiring but add inspection steps - indexing the cartridge collar with the cam key, centring the cradle with the trim gauge, and tracing contacts with the signal probe - each a short timing check.

Every step can be switched off in Items.Builder.Steps - see Configuration.

Tools

Tools hang on the bench's pegboard. A bench has no tools of its own: drag one out of the kit bag and hang it up - it stays on that bench.

Tool	Item	Used for
Utility knife	sd_tool_knife	Slitting the carton's tape
T-handle hex key	sd_tool_hexkey	The case front's four corner bolts
Cordless driver	sd_tool_driver	Driving screws - stands on its own shelf
Screwdriver	sd_tool_screwdriver	Driving screws by hand, and terminal clamps
Combination pliers	sd_tool_pliers	Crimping detonator caps into blocks
Side cutters	sd_tool_cutters	Cutting wire to length
Wire strippers	sd_tool_strippers	Stripping leads and wiring modules in
Band tensioner	sd_tool_tensioner	Pumping retaining straps tight
Multimeter	sd_tool_multimeter	Proving the circuit
Cam key	sd_tool_camkey	Compact cases: indexing the cartridge collar
Trim gauge	sd_tool_trimgauge	Compact cases: centring the cradle, trimming the carrier stops
Signal probe	sd_tool_signalprobe	Compact cases: tracing contacts, capturing diagnostic pulses

Supplies

What a build uses up. Each goes onto the bench from the kit bag and is the bench's from then on - whoever works there next finds what is left.

Supply	Item
Plastic explosive	sd_explosive	One block per charge
Charge bracket	sd_charge_bracket	One per packed cell - six come in every Extra Large kit
Retaining strap	sd_retaining_strap	One per packed block
Instrument screws	sd_screw_box	48 to the box - tip it out onto the bench
Wire spool kit	sd_wire_box	Six reels, one per channel colour, four lengths each
Field assembly handbook	sd_assembly_book	The builder's reference, on its lectern

The Workbench Item

The sd_workbench item lets players set up their own bench. Using it opens the placement tool; the item is taken once the bench stands, and the bench stays across restarts.

• Whoever set it up can pack it up again - ox_target, or G at the prompt - and gets the item back, as long as nothing lies on it and nobody is working at it
• Staff can move it, change its owner, or remove it from the Benches tab

-- configs/shared/items.lua > Builder.Bench
Item = { Name = 'sd_workbench', Limit = 2, Reach = 8.0, PackUp = true },

Option	Default	Description
Name	'sd_workbench'	The item. Item = false turns the item off
Limit	2	Benches one character may have standing at once (0 = no limit)
Reach	8.0	Metres from the player the bench may be set up
PackUp	true	false = a bench stays where it was set up - only staff take it away

Staff Commands

Command	What it does
/bomb_toolkit [tools|parts|all] [player]	Hand out what a build takes: one of every tool (default), the parts for a build, or both
/bomb_bench [remove] [force]	Stand a bench in front of you, or remove the nearest one (force: even if parts lie on it)
/bomb_plant [modules] [seconds] [strikes] [needy] [seed]	Plant a random bomb in front of you
/bomb_detonate [id]	Set an armed bomb off now - that one, or the nearest
/bomb_clear	Remove every planted bomb
/bomb_give_set [player]	One bomb of every size, each packed as full as it holds

All staff commands are restricted to group.admin by default.
