Highest Craft Possible

[Sheogoroth]

I've been fiddling around with a PF setting 3rd party book called "Chaositech" which essentially adds a line of crazy technology fueled by chaos. These items are not not magical, but you can craft them with a trained skill and no spells needed. The problem is, the craft DCs are all way high to offset this.
I know feats enough to keep the costs down, so now I'm looking for ways(items, classes, Prcs, feats, etc) to boost my craft enough.
So how high can you possibly get a crafting skill?
And if this thread already exists, please link me.

This is Pathfinder then? Well, the easiest bump is to take lore oracle's focused trance ability for a +20 to any int based skill roll several times a day.

How high are these DCs?

If 3.5 material is allowed, Cleric spell Divine Insight will boost any check by a maximum of +15. Craft checks key off INT, so enhancement bonuses can pull another +6 or so.

If 3.5 is available, we have access to Pun-Pun, awaken loop, and hivemind shenanigans (or some Frankenstein-esque combination of the three). Keeping this PF would probably be for the best, since it's slightly harder to break wide open.

The DCs are usually around 40.
Are there any dip prestige classes that add?
