both look to be the same on my BOP. I measured one and it came in at right at about 2 and 4/10 of an inch from hole to hole.

When I had to make gates from piano wire (pbresource!) for BOP and F-14 (they were all but one actually available but I had the wire and didn't want to wait) I was able to find a pic of them on Marco's site. I put that pick into photoshop, sized correctly from measuring the opening, straightened, printed a pick and used that as a guide, went from what looked by a wire gate made in Mordor to what the pic on Marcos site looked like.

It's 4 tenths. I used my caliper which breaks inches out into 10ths.

So then it would be written as 4.040 or 4.400? To a machinist a "tenth" would normally mean 0.0001", a thousand is 0.001 and everything else is is thousands, be it .400 (four hundred thousands) or 0.404 (four hundred and four thousands).

OP - I would think you should be fine. If it's just a tad to big then you could simply drill out the holes a bit to open them up a little bit. That should get you the room you need.

That seems odd that machinist would use a completely different understanding of the decimal system then the rest of the world. Seems like that would cause confusion.... But the example of 0.404 (four hundred and four thousands) could also be read as 4 tens if rounded, right?

Normal decimal math would be like the attached.

The machinist here at work uses the same conventions. I always have to think twice they they say something is half a thousandth. .0005, rahter than 5 ten thousandths.

You wouldn't say four tenths, you would say four hundred thousands. Its strange I know, But as a machinist .0-.000 is all thousands. .0000 would be tenths. We ignore the whole number, and the first 3 places after the decimal point is all thousands and the 4th place is "tenths". Imagine an imaginary decimal point after the 3rd digit. 0.000.0" so 1.123.5 properly would be 1.1235 but would be said aloud as one and one hundred twenty three and five tenths or one and one hundred twenty three and a half thousands.

Its strange I know, But it was how I taught it. I wish we could just abandon the stupid imperial system all together and go metric. No stupid 12" to a foot no fractions and all that other stupid stuff. In metric you just move the point around to change units.

Hey I know you...

Rudy is safe, by the way. I'll measure both gates and post some pics later when I get home.

By the way I've tried paperclips and coathangers before in adhoc pinball repair sessions. Never really worked out for me, they always get a little too bent out of shape.

Yeah, 2.25 inches for each gate. Here's my really high tech measuring tool.

Well here I am at the beginning of 2024. Just woke up a Game Show that has been in hibernation since at least 2016, and likely much longer. Godzilla and the Electric Bat Arcade has brought me back from an early retirement. Last time I posted on a pinball forum it was rec.games.pinball (RGP) Looks like many of you are still around.

I've been able to find most of the parts that were missing. This game is a lot of fun!

I'm down to the Rebound Gate Assembly A-13305. Does anyone have any leads on this part? Or any experience installing the above mentioned parts on a Game Show? (A-14363, or A-12511 plus 12-6657-L)

Looks like Marco has something close #A-17797-1. It's probably my best bet.

Cheers!
