Anyone saying that there is a better fork jig than this is totally full of crap. Don Ferris makes Anvil jigs and if I weren't so financially challenged I would have everything in his catalogue. This fork jig replaces a really crude one I have been using for over 15 years. I can't say enough about the amazing facility and workmanship of this product. Any doubt that this is a 50 mm fork rake can be eliminated by reading this scale. The jig has scales for every relavant dimension of a fork .
