How many times are you going to replace rivets? I would ask Steve if he could do it. Of course, T&M would prevail.

that would seem to be a "ball in play" disk, those are readily available... i would just swap it out

I'll check my parts bin, I may have one of these. I know #Boilerman could source one as well

I just completed this exercise on a BCU stepper from Flipper Clown. I could not find a tool that was the correct size to roll the edges of these small rivets in order to properly secure them. I have done similar rivets that were slightly larger with a hand tool that has a center tip and rolled interior edges to set the rivet (looks a little like a center punch). They are available on line from several vendors. But I could not find one for these smaller rivets. I ended up making my own setting tool and anvil. Results came out just fine. See before and after photos.

I also sanded out the deep groves in the disc with 400 grit wet-dry sand paper.

here's a disk i have in my parts bin, better than yours but still a slight grooving in the ball over contacts

You can carefully fill the grooves with solder and sand smooth.

The back of the BCU has a wire running across all the rivets. Solder attaches the wire to the back of each rivet so the "rolled edge" of the rivet wont be seen in my repair. But the replaced rivets came out looking very similar to the original rivets before adding the solder, like the ones in your picture.

This is a picture of the BCU with the first row of rivets drilled out. The second row is original but the rivets were also drilled out and replaced after removing the solder with a solder sucker.

Don't have a picture of the tools I made. You may find a tool on line if you search under "semi-tubular rivet setting tool". As an FYI, Steve Young at PBR can probably do this repair for you. Don't know what he would charge.

The most accessible parts you will find are probably here. The $28 punch is what you are looking for but it is out of stock.

The die kit could be used also.

I have an EZ squeeze rivet tool from Marco but found its function problematic.

I have found using a punch from a rivet set available on ebay cheaply works quite well utilising the punch, die & a hammer. This is the set:

https://www.ebay.com.au/itm/9-11Pcs-Craft-Tool-Kit-Set-Die-Punch-Buttom-Fastener-Rivet-Setter-Leather-Base/311876849223?epid=896993143&hash=item489d4f0e47:m:mIkGF3JkzURAoioWvAdMzwQ

& this is the specific punch within the set:

It is important that the dimple at the end of the punch be able to sit in the hollow end of the rivet so that when it is punched it splays the rivet end. That one you have shown just looks to have a less pronounced dimple than that needed although as you are no doubt aware pics can be deceiving.

At $US10.99 from Harbor Freight these would do the trick:

I just use an arbor press drilled out to accept a tubular roll die. The arbor press gives a nice consistent squeeze and the two surfaces won't shift. Since the press applies even pressure to both sides of the rivet, it's safer to use in plastic or thin metal applications.

Rivet Press

While a manual set tool is cheaper, it doesn't offer quite as much control. I'm not saying there aren't people who can't do beautiful work with them, but for the casual user a press is easier. Of course, there are also times when you have to hand roll, because you can't reach a rivet with the press

This press will accept dies for most common sizes and you can purchase them from Hansons's rivets. https://www.instructables.com/id/Cheap-Tubular-Rivet-Press-From-an-Arbor-Press/

I have the die kit from PinRestore and had a Harbor Freight arbor press modified to take the dies. Works great. Basically had the arbor press modified just like the link in zimjoe's post outlines. The right tool for the job.

More options.

This is a pretty standard mod on these presses. PinRestore had been out of stock for months or I probably would have just bought one his kits. I saved a little money by buying my own dies, but the PinRestore kit looked like it had a few other modifications.

I had looked at those on ebay before I built mine. I was concerned that the dies would be wrong or that the modern roll dies might not fit. I didn't want to bump that old thread, but has anyone else had luck with one of those old ones?

People that have these really like them. Much easier to store in a tool box than an arbor press

I need one of those, Ive got 30 targets to do on a target pool

I would love to see a video explaining how to use this properly.

get the hand tools, unless you are doing VOLUME of these in many restorations, its really simple to do without removing/unsoldering the target from the game... You can do other things like contact 'rollover' work and so forth with some modification or the tools in the kit. Worth the 10 bucks or so at your local Chinese-Freight.
