@farmerman,
At Williams SOnoma, they also carry a 299 dollar orange juice squeezer. It does exactly the same thing as one of those clam shell kinds that yer gramma had (and Ive inherited cause we like fersh squoze OJ).
If the orange was too big (like a giant valencia) you could add a length of copper pipe to the squish arm and walla, you could smash clam shells.
