I've been making fork bending dies as custom tools for years, and I'm now offering them as standard items. Once I gauge interest I'll likely stock several radii as standard offerings, but for now I'll make them in any radius you might need.
They're machined from solid blocks of aluminum with a 3/4" wide 90 degree vee groove in the face. They're supplied with clamp blocks, clamp bolts and an adjustable threaded bending stop. The clamp blocks are slotted, so you don't need to completely remove the clamp bolts if you're working on a fork blade with the dropout already attached. The bottom face has three M10x1.5 threaded holes for mounting.
The attached photos show a 12" radius die about 12" long, and a 6" radius die about 8" long.
Price is $195. Expect a lead time of 2-3 weeks since they're all made to order.
Thanks
Alex
