A spring loaded center punch is used to make an indentation in metal prior to drilling a hole. The indentation helps hold the drill bit in position when startin the hole.
The center of the hole is marked, then the puch tip is set on the mark. Press down on the body of the punch until the spring mechanism releases.
The force of the punch can be adjusted by turning the top of the body. Softer metals such as aluminum need less force to make a satisfactory mark. Hard metal may need more that one stroke to make a deep enough mark.
This type of punch is also known as an automatic center punch.
This is a handy tool to have around. It can also be used to break automobile side window safety glass in an emergency. The sharp point will cause tempered safety glass to shatter.

Valve stem height is typically measured using a micrometer or a caliper. The measurement is taken from the valve spring seat to the tip of the valve stem. This measurement helps ensure proper valve function and clearance within the engine.
A Tubular Spring scale.
You can make a simple forcemeter using a spring scale, rubber bands, a wooden stick, and a hook. Attach the hook to the spring scale, then use rubber bands to connect the hook to the wooden stick. Apply force to the stick, and the spring scale will measure the force exerted.
To make your own gaskets, you can use gasket material and a gasket punch kit. Trace the shape of the gasket onto the material, then use the punch kit to cut out the gasket. Be sure to use a sharp blade and follow the manufacturer's guidelines for cutting the gasket material.
