Re: 13/16" Expansion Plugs

quote Buccaneer:

If the Spherical radius stated of 1-1/32″ was half of the diameter, .812,
it would make sense to me, sadly it’s not.

OK – try this – if you want to save money and make one, you’ll take a penny and form it over a trailer ball with a sledge hammer to make it dish shaped. What’s the radius of the trailer ball?

So the Spherical Radius is …… The arc of the expansion plug continued
in a complete circle, divided in "two"? If so, that makes complete sense.
Either way, Thanks!

Now the big question is, who’s going to hold the penny while
I proceed with the sledge hammer? 🙂

Prepare to be boarded!
