Wanted to bounce a idea I had .
I’m building up a Custom bike and had a idea for for a rear disc brake .
I was gonna make a plate with matching threads for the free wheel . It screws on then I’ll mark and drill 3-4 holes and tap the hub. So you screw the plate on to the free wheel threads then the 3-4 bolts prevent it from loosening up etc. then you can bolt the disc brake to that.
Think it will be strong enough?
