Hello!
I have workbenches made of other minecraft wood like spruce. This is possible with Crumbs mod. But they are still slow :D
I guess they don't work with your mod, so if you can, please make it compatible :)))

As of 4.6.0 FWB edits the vanilla code to increase crafting speed. If this still does not work for that mod's crafting tables, it is a bug in that mod.

However, you may be able to use FastSuite to receive some benefit in those tables.
