If I were to make a bomb using nails, a small wooden barrel of gunpowder, a wick, and wax to seal the whole thing, about how much damage would it do? No buffs, no mods, just a bomb. any ideas?

Would the damage go up if it were a metal barrel? Adding oil or tar?

The way we've been doing it so far, is I take a roll to see how good my PC crafts the bomb. than based upon that roll is the damage. for a poorly made bomb, it usually just lights on fire. no real explosion, for a mid-grade one its usually a 2d6 to everything within a 15 foot range, and for a well made one its 3d10 to everything in range, plus possible force damage, with the possibility of a acrobatics check to dodge and take half damage. Is there anywhere with real standards for this type of weapon?

The Dungeon Master's Guide has some rules for explosives in the Dungeon Master's Workshop chapter.

Some of it, i.e. a bomb is even part of the basic rules.

As an action, a character can light this bomb and throw it at a point up to 60 feet away. Each creature within 5 feet of that point must succeed on a DC 12 Dexterity saving throw or take 3d6 fire damage.

Based on your description, maybe a fragmentation grenade fits better as mechanics/damage type orientation:

As an action, a character can throw a grenade at a point up to 60 feet away. With a grenade launcher, the character can propel the grenade up to 120 feet away.

Each creature within 20 feet of an exploding fragmentation grenade must make a DC 15 Dexterity saving throw, taking 5d6 piercing damage on a failed save, or half as much damage on a successful one.

If you think the damage is too high, feel free to adjust it based on the check or increase the costs. This is a typical DM fiat question so: "The DM decides the mechanics and how much damage it deals, the references I posted are just for inspiration."

    \$\begingroup\$ You could probably relate the 150 gp cost suggested for the bomb back to the crafting rules . . . although by RAW, each bomb is going to take a while to make. \$\endgroup\$ – Neil Slater Oct 17 '17 at 13:29

    \$\begingroup\$ Sounds more like a make-shift claymore than a grenade. Our DI taught how to make them with tape, nails, C4 and an ammo box (which would be smaller than a firkin. en.wikipedia.org/wiki/English_brewery_cask_units \$\endgroup\$ – Slagmoth Oct 17 '17 at 17:14
