In the vanilla game you would receive 6 Firewood from the action 2 per Chop.

So I have created a couple of scripts to suit the user that still uses the default 3 Chop Animation for Speed but adjusts the value of Firewood Received Per Chop. Now there are mods that make mining and chopping unlimited ( Unlimited Woodwork and Mining ) where by the animation repeats until the user interrupts but the amount of material you receive stays at the vanilla default value, which doesn't help if you want to obtain the materials faster. So I decided to look into it and found that the rules for the mods that change ore mining ( Faster Mining Plus SE ) can also be used to adjust the amount of Firewood you receive by altering the script in the same way and modifying the resource received value.

I use the Camping and Frostfall Mod in my Playthroughs and it can be frustrating how much time you have to spend at the chopping blocks in game to obtain the firewood you need to be prepared for your journey through Skyrim. So I was looking around on the Nexus here at mods that effect harvesting, there are many for plants and animals and quite a few for ores and mining, however nothing that speeds up or reduces the amount of time you have to chop wood.
