Re: core plugs

So, I did google it. I think the difference is that a welch plug is the type used in the king pin cap. It is a dished shaped disc that drops into the bore, then you peen it with a hammer so that it flattens out and creates a tight interference fit. Whereas a frost/freeze/core plug has a flange with a radiused edge and a slight taper that starts into the hole freely and then needs to be driven in for a final seal. I think I just learned something, and at my age too!
My Dad was stationed overseas during WWII, while going through basic and awaiting deployment to Europe he made the most of the British lament "They are over paid, over sexed, and over here!"
