"Looks like about the radius for old school "continental" style fork blades. How are you going to hold down the tips?"

]Yes, from whay I've read/browsed the 9"(+-) will produce that style, and the smaller radius more of a "French tip" with the bend mostly near the tips.
I googled bicycle fork bender http://isearch.avg.com/search?q=+bic...=hdr&sap_acp=1
and found a lot of framebuilder sites(mostly flicker)with nice pics to look at. There are several ways to go regarding the cap, check out the link. Probably copy something like the Hammil cap, looks basic and doable for me.
Another question for the forumites, is dry lube or wax ever used when using this type of bender? If not why?
thanks, Brian
Of course there's no need to make a constant radius block, or bend a constant radius curve in the blade. I made my bender with a block with an involute profile. An involute curve is a decreasing radius curve used on gear teeth. It's technically the path traced by a point on the circumference of a circle as the circle is rolled along a plane (for gear teeth that's important since there's no sliding contact) and incidentally it's a very "pretty" curve.
As for wax or lube, not used by most I think since there's no sliding contact of bender and tubing being bent.
