Homebrew PCBs

Note:  This goes way back in history:

Regular eyelets are completely circular like a tube with a flared top and
not suitable for PCB use.

The correct type for PCB eyeletting are split lengthwise and not completely
circular.

 

The reason is that the circular one, like a funnel, solders to the bottom
layer in a wave soldering machine and fills up with solder but there is not
a capillary force to go over the edge and back under the eyelet top to
properly solder the eyelet to the top side copper layer.

 

With the split design solder wicks out and properly solders both sides.

I was never very good at soldering when I was young. Now that I am in my
late 50's and arthritis has started to affect my hands, my soldering skills
have become worse. In particular I spend more time repairing solder bridges
than the actual soldering. All this heat on the PCB results in a few pads
lifting off. 

This is where the eyelets could come in. I would like to use eyelets as
rivets, forcing pads back into place that have peeled up. I've seen some
on-line but the prices seem rather high. Does anyone know of a source of
reasonably priced eyelets?
