Hi, I have been on this forum for a while but never commented on any thing, anyway i signed up just so i could post this, you dont need any special tools to bend fret wire, you can use your fret pliers, watch this video and go to around the 9 min mark to see what i mean

Also you can make your own fret caul,

any way hope this gives you some ideas, love the build.
