The trip wasn't entirely wasted.  One of his flippers is sticky (which I noted the last time I was there, but it was particularly troublesome) and it needs to be rebuilt.  I do have to ask - I have read that rebuilding the flipper assembly with modern components is a good idea.  Can the assembly be replaced with this: http://www.pinballlife.com/index.php?p=product&id=172&parent=107

That assembly is almost correct, but not quite.  It has parallel wired coils, and BK needs to keep the original series wound (or is it the other way around, I'm really tired, but either way it's the wrong style coil).   The EOS switch is also the wrong type, you need a normally closed and that one has a normally opened switch.

I built up a parts list when I did mine with WPC hardware,  and here's the info for it....

So....  Why are rebuilding flippers a waste of money?

This answer better be good.

Even when the coil stop and associated parts have mushroomed?

smartbomb2084:
It is obvious you need more experience and less mouth.

When the flipper coil plunger and the coil stop have each lost 3/32 of length from wear and the coil plunger link is slamming the end of the coil sleeve and hanging up when the flipper is activated no amount of cleaning will fix it... period.

Sure you can file the mushroomed ends down but then you get uneven flippers with a stroke that is way too long and the plunger link slams the coil even more. By this time the roll pin that connects the plunger link to the plunger is swimming in an egg shaped hole twice its normal size.

Keep the BS coming... It is truly hilarious!

On most games I'd agree with jim.  Often a total rebuild just isn't all that necessary.  A good cleaning will get you most of the way there as often as not.  True rebuild kits aren't even out there for many games.  If they were truly necessary they would exist.

On a Black Knight the flippers tend to be WORN OUT and you need every ounce of snap to get up those ramps.  Rebuild on a Black Knight.
