Recessed parts won’t come off.
Bolts break.
Nuts strip.
Cracks appear. <\/p>\n\n\n\n

Honestly, without machine tools, it’s basically difficult to safely and confidently remove or repair things.
When removing a broken bolt, you might be able to drill one by feel and get it out, but with ten bolts the odds drop.
You want to finish safely and reliably. <\/p>\n\n\n\n\n\n\n\n

A bolt breaks clean off, then strips and won’t come out.
Just one bolt, but that one bolt eats hours… Ever been there? <\/p>\n\n\n\n

When a bolt breaks, it doesn’t come out easily.
The bolt broke because it was fused that solidly…
There are sketchy bolt removal tools and chemicals everywhere, but unless you mess up and destroy the head, it’s tough. <\/p>\n\n\n\n

A drilling jig for removing the anti-theft shear bolt from a key cylinder.

With something this simple, you can drill reliably close to center.
Making something like this definitely requires a lathe.
Without one, you have to go by feel, which is extremely risky. <\/p>\n\n\n\n

Similarly, when the top bridge surface isn’t flush, removing that broken bolt is tough.
If you turn a round rod on a lathe to make a mandrel like this, the work goes much smoother.
It’s not so much a removal skill as it is having the right idea and the right machine…
It’s all about equipment. <\/p>\n\n\n\n

Sometimes a bolt just won’t come out no matter what.
A seized bolt stays put whether you cool it or heat it\u2014it’s genuinely stubborn.

In cases like this, you weld a nut on and work it back and forth gradually, having a conversation with the threads as you remove it.
This scenario also needs a welder or you’re stuck. <\/p>\n\n\n\n

As bikes age, troubles pop up in places you’d never expect.
Without the ability to handle irregular situations, work stalls and problems don’t get solved.
First comes equipment, then creativity… basically it’s all about tools.
Tools rule!
