Review on ⚙️ Compact Precision Center Punch Spacers Required by Tony Wylie

I'm a retired locksmith. Military and civilian business. I've already hit five coins. Three of these resulted in shifts from the center by as much as 0.025. The top and bottom of the set don't quite find dead center - even without the coin in place. When using a 2lb brass hammer (as intended) the top of the tool tends to "jump" causing the coin to be slightly off center. I will try to use C-clamps to "fix" the top and bottom together. The problem is that the C-clamps now make it difficult to hold the stamp set on a hard surface.
