...and which one do you trust more for your guests and kids?

All looking amazing, Yves. I'm curious about your alternative to the yellow ground cables. I presume you made these yourself with a crimper? Do you have any details on the ends you used and the crimper type? I like this method, though I have reason to believe my yellow ground wires might be in better shape.

Quoted from Arcane:

Jsa,
Yes, I made them with a crimping plier and some lugs that I got from Digi-Key. You can probably find the same thing at Auto stores. Just make sure that the hole is big enough for the bolts (#8). The trick is to stretch the braided mesh until it becomes like a multi-stranded wire and then insert it into the lug. Very easy and very quick to do.
Yes, I know your feeling about these horrible Bally ground connections. You may think they are in good condition until you pull them out of their sheath and discover what is really going on in there. Plus the increased resistance of these 40 plus years connections offers a significant risk, in case something goes bad.
I want my machines to be as reliable and safe as possible. In addition, it looks so much better than the original Bally pieces of metal and you can rewire the ground in a more correct way. Bally, in their original design, created a lot of ground loops throughout their machines. As you may know, a ground loop will induce some parasitic noise and may cause strange behaviors that will take forever to diagnose. The way I have it, is to distribute the grounds in a tree like fashion, with a trunk line connected to the Line Filter and multiple branches never touching themselves.
Yves

I'm with you, 100%. As I restore Future Spa, my intent is to re-work the ground line similar to later stage machines that used the "tree" like method you're suggesting.

What's your plan with the metal behind the PCBs in the backbox? Are you replacing that with new metal?

Also, any idea what gauge these things would need to fit the ground braid properly? I'm guessing 18 is fine but maybe it's thicker than I think.

Having just clear coated cabinet parts for two months, I will say that I'm all for the going pro route. That stuff is intense.

A funny picture: the ideal outfit to spray clear coat on Bally playfields
[quoted image]
Yves

That's a familiar outfit. One thing I found was that the sleeves tend to push up (of course it may be because I have freakishly long arms) and that cutting the tops off an old pair of socks make good sleeve extensions. Sometimes I forgot to push my hair into the hood, that was always an interesting discovery before bed.

Another tweak I would make for next time is a full-face mask. I kept having to clean clear coat triangles off my face under my eyes.

Finally, I highly recommend the P100 filters:

I found that I could still faintly smell the clear through the ones you're wearing so I switched up.
