spot face Q / advice....

[hardtimes]

Any you guys do your own 'spot facing' of head bolt/nut surfaces ?
Any recommendation for someone who wants to do such work, i.e.- don't; yeah doable; here's what you need and how; precautions , etc

Usually, I take parts to machinist and spend enough in time/transport/$ , that I coulda bought tool stuff and tried to help myself. I like doing whatever is doable for my hobby
