Quoted from cottonm4:
pictures, please. Was it hard to make? How long of tube rivet do you have to use? So many of my bad sockets are just from the material at that brass washer getting loose and not making good contact. And I think the looseness is from the fiber insulation washer drying out and shrinking.
Actually, the brass eyelet, clinched end, on the inside of the base breaks.
When this happens it causes a slack to the assembly.
A small brass ring will pop out if you cut the contact rivet head off.
If there is still a good compression to the assembly, then re-striking the eyelet is sufficient
to re-clinch the assembly together.
As for eyelet size, GS5-7B Brass. This size seems to work best... I have to pre-flare the end...
and then the clinching gives a better results.
I had to buy many sizes to find the right size... So -7B is the smallest that works.
Other sizes were not long enough. -5B, -6B ect,etc,etc.
-8B might work but I have not bought any to tryout.
I have had to buy brass tubing at the hobby shop and use it to make
the eyelets to clinch switch stacks to European pinballs.
A tough game to fix, that was time consuming, was Top Speed.
It was just one thing after another... But, I was able to fix the lamp sockets.
( The drum lights to the back box were a pain )
As far as the tools you need two parts... A base with the inverted cup and hole,
and the clincher that has a nose that fits into the hole of the base.
the clincher should have a small curved rounded base that flares the eyelet end.
I need to get a better base made that has one side of it cutoff to fit "lay-down" style
lamps. "rollover button" style lamp sockets.
eg Bally E-120-155, E-120-99 etc,etc,etc.
As for semi-tube rivets, steel rivet size -18 seems to fit along with size -19.
TSC0818,TSC0819. It depends on the lamp socket.
Bally had an inverted cup stem rivet to some of their lamp sockets.
In all, when the lamp sockets are all knowingly good the game looks better
and is fun to watch if you have a feature that has strobing lamp fx...
I just finished the lamps to a Bally Freedom... it is so nice to hit the
spinners and watch the wheel lamps wiz around and around.
