Shortly after the initial posting I got inquiries about re-raking and aligning existing forks. I'm happy to provide that service but its more involved both in terms of the actual craft work and changes to overall front-end geometry. A low and tight re-rake of an existing fork will lower the front end more than a longer, more gradual rake. Low and tight generally won't be the way to go in those circumstances; that said the particulars are open for discussion. One might have a replacement fork thats a bit longer and a suitable candidate, so that sort of thing can offer possibilities. Generally I recommend a new fork because it allows one to hit all of the numbers you want to hit. Re-raking is nearly always a larger compromise than I'd want on the frames in my own stable. But drop me an email if you want to discuss your situation & needs wrt a re-rake or alignment.

Tom Matchak has a white paper about the effect of re-raking on frame attitude and hence head angle. He shows how the rake-added fork needs to be somewhat longer to maintain the original front ride height and head angle.
