Adjustable pin metal frog
 

I think I remembered seeing one of these on line somewhere years ago. Used for plunging multiple holes in glass in a pre-arranged pattern. Can anyone help?

Florists use them to hold stems in flower arrangements.

I have seen them at Michaels stores in various sizes.

Remember that the base of them is typically lead and the pins themselves are going to be metals that you won't want to inhale the fumes from so work hot and quickly.

You could use the frogs for the pattern and then push deeper with one of those mig welding points that come with the green mark on one end.
I think they were titanium but I do remember that some of them came with thorium in them.
They had red marks on the end and you really don't want to mess with those. Entirely too poisonous.

The tool that has the removable pins for rearranging is called a Vin Pin

NOW I remember those.


Don't get old.
My memory sucks swamp water.

this guy used to make them, not quite the same as the vin pin but very good & functional.
