Or is it? I got a batch of coil sleeves, and they seem like maybe they aren't exact?
First I want to ask if I'm the only one who just trims down a coil sleeve if is too long for the application? Is there any problem with doing this?
Last night I fought with some Coils in a target unit on my Flash, and as usual, I had the problem with the sleeve coming out, but then the new sleeve won't go in. I've ready other posts talking about how sleeves go in very hard on some williams flipper coils. This wasn't a flipper coil, or even one of those HUGE reset coils like they use on Bally games. To the eye all my coil sleeves appear to be the same, but I haven't taken a caliper or micrometer to them or anything. But after fighting with it all night, This morning I tried a new coil sleeve and it slipped together with no problems.
ALSO- Has anyone else found that hollowing out the inside of a coil just slightly, with a drill slightly smaller than the coil hole, and just make sure the walls a smooth? I've tried going the other direction and sanding down the Coil sleeve to it's smaller to fit in the hole but I can't seem to find anything to hold the coil sleeve, and then make it spin fast enough to use sandpaper to take off a little bit. When I was finally able to get something to work (not very well) it ended up roughing up the coil sleeve, sort of negatiting any benefit from change in size.
FInally, If you get a sleeve stuck inside of a coil, has anyone else taken to using a sabre saw to cut a slot, allowing the sleeve to come out, Or another way I found was to use the same drill that I used to hone out the inside of the coil. It seemed to get inside the coil sleeve and sort of rip it out of there.
Anyone have any better way of dealing with the sleeve-too-big / Coil ID too small problem? If so I'd love to hear them! Or ways you've found to make the process easier.
