It's 4 Amusement Only, the EM and Bingo Pinball Podcast. Welcome back to 4 Amusement Only. This is Nicholas Baldridge. Continuing our discussion of how to clean your machine, I want to talk about how to remove the lamp rebound springs from a bingo playfield. These springs are very fragile. They're made of a tiny strip of metal that is stretched between two steel posts and it is very easy for that thin metal to shear off or actually be pulled from the tiny kind of flange that holds it in place. So you don't want to exert vertical force I'm John Papadiuk, Black Water, Kaneda's Pinball Podcast, Twippies Awards, translite and look around the lamp sockets what you'll see are two post holes where the spring attaches and as you can see they're driven all the way through the playfield so what you have to do is knock it out from below what I did I'm really cheap so I buy cheap stuff. I got a punch set. I think it was five dollars and they have coupons all the time so you can get it for less than that. But with this punch set you simply place the punch underneath and you can put it in the The first thing you do is to take a piece of one of the posts, then take your hammer and smack the punch and it will knock the pin out. What I do is alternate back and forth. Again, I'm just pretty cautious with these because they're not replaceable. So I try not to damage them. What I'm concerned about is if you take a I John Papadiuk and I see you next week It actually shear off that fragile thin piece which actually acts as the buffer between the lamp shield and the ball So taking out one of these is also something where you have to be concerned about the effect that it has on the playfield surface. If you are way too happy with the punch, then it's going to exert a whole lot of pressure on the playfield surface and actually either bow it outwards or damage it. You know, chunks will fly out. So you want to be careful. Don't come at this with your whole strength. You want to use tempered blows in order to get this out. If I have a particularly stubborn one, then I will actually use my old friend the rubber mallet. And this allows, again, some of the force to dissipate. I'm using my force to it makes me feel better and I'm using more force to do something like that oh the other thing I should mention is if you take the playfield out at the game it makes this job million times easier I and if you have it resting on some kinda surface or on some horses for the light It will make this a lot easier. Now, you've taken out these springs and there's eight of them. What do you do? Cleaning them is not incredibly easy again due to their fragility. So, one thing you can do is just be very careful and very slowly work your polish in 99% of the lamp springs that I've seen are absolutely filthy and they require a bit more consideration. So this is something that I will use a tumbler for. You have to make sure that you have fine media, very fine, and then spray a couple bits of metal polish in there, liquid kind, and see what happens some of the time the uh... lamp springs are rusted and when a metal becomes rusted it actually eats away part of the material so even if the tumbler is able to remove the rust spots you be left with a pitted surface So the first thing you should do is just be ready for it not to be absolutely perfect. But after it's done the difference that you see is incredible. I mean He's shiny metal piece that's right in front of the playfield lamps uh... it's very visible to the player and it's very eye-catching when it's shiny it's also eye-catching when it's disgustingly filthy but for a different reason I have three bingos at the moment two of them I have punched out the I'm lamp springs and polish them and then the third one is ticker tape my recent acquisition an operator had previously applied some kind glue or something on every single post in the game I assume that they had some problems with the posts weakening overtime in some other games and so they did this is a preventative measure I don't see anywhere where it was really necessary to do this kind of repair especially on every single thing in the game the operator who did this got a little sloppy and they managed to get the glue on the outside and inside of these lamp springs which are otherwise in pretty darn good shape um you know they'd be candidates just for polishing in the game if it weren't for this and so uh... because of the unknown quantity of the glue that they used how strong it is and what the bond is on the surrounding areas of the playfield I haven't punched those out and I don't know that I ever will uh... I'm just a little too frightened of what's going to happen when I do it So yet another piece of advice is examine the area around your lamp springs and make sure that it's not going to have a detrimental effect when you knock that thing out. Another tip is to brace the opposite side of the playfield surface to absorb some of the impact. One thing that you can do is to I'll take a wine cork and then cut out a slit and slide it over the post that you're about to knock out. And this will help absorb some of the impact and recoil that will happen naturally after each blow and will hopefully help dampen the forces on the playfield which might damage it This is another thing that I only do pretty much once and then I just maintain and I do it to try to get a consistent beautiful product out of it. But not everyone agrees with that and that's certainly a valid opinion to have. If you don't want to do that, I completely understand. There's so much risk of damaging your game that some people don't find it worth it. So you got the thing out, you polished it, now you need to reassemble it. This is where your friend the cut cork is going to come into play again. Now you want to cut it down a little more so that the top part of the post is visible to your hammer and you're going to want to tap it in. Again you're going to want to be gentle so this is another spot where I use my friend the rubber mallet and it works very well. You can go very slowly and tap, tap, tap away until you get to the appropriate depth. It's pretty easy to see from the bottom of the playfield if you've reached the appropriate depth as well. It's another nice thing about bingos. If you see metal nearing flush with the bottom of the playfield, then you're pretty much in the right spot. A word of warning when you're doing the reassembly. It's easy to have the springs unwound an extra turn and this will give your spring a very loose feel when the ball hits it. I'm certainly guilty of doing that. It's really easy to do. So pay attention and go slowly and you will have some great results on your game. Well thank you very much for joining me. My name again is Nick Baldrige.
