It is possible that I have over-reacted. The weather equipment on my car is held on with press-studs and they keep falling off. I've got a little punch to peen them over, but it always goes crooked.
I bought this inferior Chinese arbor press for pocket money. It's trash.. My favourite thing about it is that the bolts proudly say "4.8" on them - this means they're about as stretchy as inferior steel and about as strong as good quality chocolate.
No, I don't own an optical centre-punch, why do you ask?
Spotting.
Boring - like this blog.
Here's the punch in the press.
And here's the hood refurbishment.
