Items? Not that I know of. Tinker's Construct lumber axes fail because the tree is too large.
Oh, while we're on the topic of Thaumcraft 4:
I'm looking for a way to procure a large amount of research points for aer, aqua, ordo and terra. In roughly even proportions. Maybe less ordo and more aqua. What can I use? I've been chewing through stacks of sugar cane and nether wart in deconstruction tables and it's not really giving as much as I'd like to have. Most stacks only yield 4-5 research points for the four combined, and I can easily use hundreds.
haven't tested my iron tinker axe on natura red wood (there's no XL ones active on server I play) but large jungle trees only take 1/6 of its dura ...I think manu TC axe will easy bring down largest of all trees no prob especially if its upgraded for durability as it should be done.
Are there any items other than that axe from TC that can cut down extremely large trees easily? (thinking the sacred oak from... I think natura?)
Thaumacraft adds one special axe that brings down all of tree at once...and It can be enchanted to be unbreakable
