Default Bonding a steel pin to copper sleeve.

For the game of steel tip darts, I have some hammerhead moving points
that thread into the dart barrel.
http://www.edarts.net/st_darts/hhpoints.shtml The moving points are
supposed to prevent bounce outs if the point hits a wire on the
board. I don't want the points to move though.

Thoughts on these approaches? Other ideas?

Thanks,

While I am at a bit of a loss to see why you want to do this, in the
finest traditions of this newsgroup, allow me to show you a diferent way
of approaching the problem.

They make a screw in tip (non-moveable)to replace the hammerhead spring
and tip assembly.

While my springs are actual spring steel, and probably weldable, you can
cut a small diameter piece of steel to fit behind the tip and bottom out
inside of the dart, they are not drilled too deep, and its a reversiable
modification.

Dont worry too much about the weight difference, until you put them on a
sensitive scale, you will find they are not as close as you may think,
and it takes a lot of epoxy to make up for a small amount of tungsten. I
had to drill two tiny holes of various depths to equal out all three
darts.
