Not enough weapon recipes in the game IMO.

EDIT: 1.1 released.

Explosive types:

Homemade Frag Grenade
Ingredients: 50 rifle powder, 12 Legion Denarius, Turpentine, Tin Can
Requirements: 40 explosives, Workbench
The explosive mixture of rifle powder and turpentine has enough power send its payload of metal coins into anyone unlucky to be caught in the blast at lethal velocity.

Homemade Incendiary Grenade
Ingredients: 30 flamer fuel, Wonderglue, Abraxo cleaner, Tin can
Requirements: 50 explosives, Demolitions Expert, Workbench
Slow burning flamer fuel added to the mixture of Abraxo cleaner and Wonderglue creates an explosive cloud of flame that clings to those within and continues burning. An unpleasant way to go, to be sure.

Unstable Microfusion Cell
Ingredients: 24 Overcharged Microfusion cells, Nuka-Cola
Requirements: 60 explosives, Demolitions Expert, Workbench
Being an expert of all things explosive, you have discovered the exact right amount of sugary Nuka-Cola to add to an overcharged Microfusion battery in order to cause it to violently explode on contact (and not in your face!). Explodes on impact.

Homemade Pipe Bomb
Ingredients: Lead Pipe, 2 Dynamites, 100 BB's, 200 Pistol powder (makes 2 Pipe bombs)
Requirements: 70 explosives, Demolitions Expert, Workbench
Deceptively simple looking, this explosive is a marvel of improvised explosives. A stick of high power dynamite, infused with extra powder and steel BB's, is placed inside a lead pipe, giving extra killing power. While extremely deadly, these explosives are heavier than most.

Homemade Multiblast Grenade
Ingredients: 1 Absinthe, 1 Nuka Cola Quartz, 1 Turpentine, 10 Flamer Fuel
Requirements: 75 explosives, Demolitions Expert, Workbench
The pinacle of thrown explosives, this mix of standard explosives with exotic and unknown chemichals creates a blast of flame so intense most organic enemies are killed instantly. The extremely high temperature of the blast can even severely damage robots and powered armored foes.

Improvised Pulse Grenade
Ingredients: Fission Battery, Scrap electronics, 20 Electron Charge packs
Requirements: 45 Science, Workbench
An overcharged fission batter rigged to explode on contact. The high voltage (but low amp) electrical blast is merely painful to humans, but can turn electronics into worthless scrap.

Homemade Concussion Grenade
Ingredients: Box of Detergent, Duct Tape, 2 Scrap Metal, 150 Pistol Powder (makes 2 Concussion grenades)
Requirements: 35 Explosives, Workbench
A lightweight grenade made from a highly explosive mixture of gunpowder and detergent, wrapped tightly in duct tape and housed in a cheap metal grenade. This grenade doesn't have much lethal power, but it's sure to knock anyone nearby on their ass.

Pepper Powder Bag
Ingredients: 5 Jalapeno Peppers, 2 Radscorpion Poison Gland, 2 Ant Nectar, Cazador Poison Gland, Flour (makes 2 Powder bags)
Requirements: 55 Survival, Campfire
A potent mix of spicy peppers and natural poisons, mixed with a finely ground flour to allow easy dispersal. This powder bag can disorient or even temporarily cripple an enemy.

Fire Bottle
Ingredients: Whiskey, Scotch, Vodka, Turpentine, 2 Fire Gecko Hides, 2 12 gauge shotgun shells (makes 2 fire bottles)
Requirements: 65 Survival, Campfire
A volitile mixture of alcohols and turpentine is mixed with fat rendered from the hide of Fire geckos, which is just flame resistant enough to stick to an enemy for a while before being consumed in the raging inferno. The mixture is ignited with a simple shotgun shell.

If you've got any ideas for new grenades or if my current files have any issues let me know. :foodndrink:

Also, if you've got any tips on creating new explosion types I could definitely use them.

Cool. I love crafting recipies. Particularly for weapon skills that aren't so common as guns. I'll try this out.

Sounds nice.

Requirements are a little high, but great! I hate how rare good explosives are in this game, this fills the void nicely.

Homemade mines and timebombs would be nice. Something with a really big explosion! Like, requiring a mini-nuke, and then... some other stuff.

I'm planning on a homemade version of C4 that you can trigger with a detonator, but homemade mines already exist (powder charge) so I don't know if I'll make those.

1.1 released with 6 new grenade types. Check them out on the images section, I think I'm improving. I censored the language on the pulse grenade lol, didn't know the rules for profanity on NVNexus.

Except for the multiblast, that one svcks and is basically just a placeholder for now.

I would really like to see some Gas grenades, or Flashbangs.

-Exo

Version 2.0 released. Includes a stun grenade, a poison grenade, paralysis grenade, toaster mine, and briefcase nuke.


Also included is a partially functional teddy bear bomb. I couldn't get the physics working but the model was really cool so I left it in there. It's functional as an explosive but doesn't show up in 1st person view and looks wierd when you place it (the model stops in air when you replace it, but the invisible collision object drops like a normal mine).

This is awesome. Will surely download when I make my Explosives character (now started an Unarmed one).

Freaking win. Too bad about the physics issues though.

I'm not an explosives guy but this does sound neat. I'll be sure to DL it.

Just one thing, change "Fire Bottle" to "Molotov Cocktail" since, they are one and the same.

There are already Gas Grenades and Stun Grenades but -> the Stun Grenade has a broken fatigue damage effect(it can be fixed with scripting) and the Gas Grenade has no effect at all.

Both are useless against NPC's in their current state, the Stun Grenade does have a fairly large concussive IMod effect that effectively disorients the players camera view.

I would expect them to get ironed out for one of the DLC's.

As for the OP only the Pipe Bomb seems interesting to me as its the only item that would seem like anything other then just more of whats already there.
