Not sure if this is fixable, but it'd be nice if you unlock it alongside the Double Steel Furnace since that's what you need to craft it. Currently, it unlocks with Steel Processing - meaning you just have a useless recipe until you get the mod's research, which is a bit annoying.

Taking a look the furnace recipes unlock when they should.

The Double Iron recipe they use is actually unlocked from the very start of the game.
When i have some free time I could probably get this to unlock with the Double Steel Furnace

I've just do a PR to update for 2.1 and have included the change for the double iron recipe at the same time.

pog, thanks. Hope it gets added to the 2.0 build (or 2.1 releases soon-ish).

It wasn't easy to do and seeing as changes where needed for 2.1 compatibility anyway I opted to just do the one set of new code and make it for 2.1
Unfortunately I don't have access to push the update myself, so we need to wait for Raid to pop up and release the new version.

alright.

when can the update to 2.1 be expected

I've been unable to get a response from Raid, I pushed the PR months back when 2.1 was experimental.

I've got a few other mods to fix, but in the next few days i'll look at relisting this mod for 2.1 until i can reach raid.
I just need to change the dependencies on my mods to reflect it at the same time

@mat1k Any joy with getting this one re-listed?

Probably be this weekend sometime.
Broke my arm, so taking a little longer to type and test.

You are a marvel of our time! Thank you.
