Sierra upright pinch bolt snapped :(
Arrrrghhh!  After ages trying to get the hub pinch bolt off I've managed to snap its head off (don't ask me how).
Are there any other options than drilling it out? The bolt must be reeeaallllyyy seized up.

I had one do that all you can do is drill it out start from one side with a small bit and go all the way through and go up in size each time I only
takes about 20 mins.
Then when you pinch it up use a longer bolt and block nut.
You can do the same on the other side.

If any of the bolt is proud of the hub weld a nut on to it, the heat from welding often helps to release a siezed bolt. If that fails get the drill
out
