Hi all Sorry I have been out of town for a few days and the connection was a bit intermittent. I am back home now so usual service will be resumed...
Daddy gloves gets the 'point' tonight for getting 25 first - that is 23 full teeth and two halves making 25 points...

Uh, Ralph. What am I missing?
Two halves make a one. Twenty three plus one is twenty four.

Dennis,
Half a tooth at each end of the 2 inches measured makes two half teeth at each end (2 points) plus 23 full teeth (23 points)...
...tpi is calculated from the centre of the tooth.
