Part of #959 Recipe changes.

Void Chassis

Current	Suggested

Reasoning: Reduces the number of crafts by eliminating iron bars. Iron cost change is just 1 ingot.
Grains of Infinity is basically free or cost 1 deepslate. Not exactly a cost increase in my opinion.
Lore Aspect: Grains of infinity is what binds the iron into a frame.

Infinity Bimetal Gear

Current	Suggested
	Suggested: Just remove the iron nuggets. 4 nuggets feel like an unnecessary craft

Alloy Smelter

Primitive alloy smelter is removed.

Current	Suggested

Reasoning: Gears and Chassis are much easier to craft, and directly affect this recipe. Since we no longer have access to alloys, the ingredients of dark steel (obsidian and iron) are added to the recipe. Cauldron felt out of place in an alloysmelter. Its cheaper in terms of iron required and thus should make it more appropriate for early game.

Enchanter

Current	Suggested

Reasoning: The recipe is closer to enchanting table and also incorporates a lectern as the "chassis" like other machine blocks. It also makes sense to use it because of the shape.

Stirling Generator

Current	Suggested

Reasoning:
Removes alloys and substituted it with its components. Piston felt out of place, replaced it with deepslate as it fits the theme (furnace floor).

Nothing to add apart from these all seem like reasonable changes. Thanks for taking the time to document the proposals!

Going to close this issue for now. For new changes, I will create PRs directly and link them back.

Void chassis, alloy smelter, enchanter and stirling generator changed in commit 473702f
