    mine is not really home made so to speak, but designed it at home and got Shapeways to make the 2 parts and then finished it off with some bulb sockets and switch.

    It is a 6vdc portable bulb tester (555 wedge, 44/47 socket and comet matrix lighting), led lit mod tester and great for comparing 2 x leds or bulbs next to each other for the 44/47's and lastly a torch and is portable because of the internal battery pack.

    I built this years ago to help level games or change legs. It proved very useful. The top wooden part is a bit bulky and could be done better but you get the idea...

    Not really a tool, but a tray/table/bench which not only stands horizontal on a normal table - but also remains horizontal when placed on a pinball machine.

    Stopping the need to balance screws, nuts etc on the lock down rail and also meaning I know exactly where I put the last screwdriver I used.

    Screwed down the soldering iron holder as well.

    Best of all, it took me less than hour to knock up.

    I suggest some felt on the inside of your table so as to not scratch your games. Simple add-on to make it even better (if you have not done so already)

    Quoted from Whysnow:

    It's got rubber on the inside, which not only stops any chance of scratching, also means it doesn't slide down the rails.

    The jack cup was held by a bolt that I removed and replaced with a longer one. This jack has the same setup I think.

    Like most have said, I have re-purposed tools... both are from Iphone repair kits... the plastic tools I find are great for removing ICs and the suction cup to aid in removal of backglass.

    It seems like you would be likely to bend the legs using that as a lever to pop chips out of sockets. I'd recommend a proper chip puller--they're only a couple bucks on amazon.

    As for the backglass, are you missing the lift channel? Gatecrasher sells the metal ones for classic Bally games:

    [edit]: Oh, that's hardbody--that probably uses a plastic lift trim. One of these might work:

    I use two of them to essentially pull the chip out but had to use one had to take a photo.

    This is not a homemade tool but it comes in very handy at times so I thought I would let you all know about it. It is called a hand vise, or machinist hand vise. If you search Ebay for "hand vise" you can usually find one for $10 to $15 dollars. There are some for sale there now.

    THere are different sizes. Mine measures 3.5 inches from the pivot pin to the tip of the jaws.

    I found mine at a local auction and had never seen one before---but I knew I wanted it immediately.

    If you have ever had to struggle with clamping a piece of metal in a pair of vise grips so you could file on it, you will appreciate having one of these units in your tool box. If you need to clamp a piece of metal and hold it tight with no slipping, a hand vise is what you need.

    I needed to open up a hole in this pivot bracket and a hand vise is a perfect compliment to a Dremel tool.

    I wasn't sure how much use I'd make of a tumbler so rather than buy a commercial unit I put one together using a car wiper motor and a piece of pvc pipe. Works really well. Also in the picture is my version of an ATX bench power supply.

    It just showed up in the mail all on its own. I'm not sure how they determined who they sent one to because I don't order that much from Digikey.

    Nice one. This looks just like something my dad would have made. Every old appliance we ever had ended up dismantled, with motors, springs, screws put away for later use.

    Got sick of dropping screws into the inaccessible areas below my WH2O ramps and didn't like any of the pickup tools i could find, so i made my own. It's just a very small neodymium magnet jb-welded to a section of coated wire coat hanger, but i find it indispensable. Tiny, just the right amount of flexibility, and strong enough to pick up anything needed without getting annoying stuck to everything around it.

    Also not exactly diy, but I repurposed an auto repair cart as my pinball work station. Works great. You can adjust the surface height and it will slide right over the pinball cabinet while the playfield is up, and works great ad a soldering platform. I roll it away into another room to tidy up when I have guests over

    Pinball silverballs only cost about a dollar. But if you have several pins and some of those are multi-ball pins, silverball costs can add up. I have had success polishing and buffing scratched balls with my buffing wheel but I wanted something else. I finally got that "something else" prototyped yesterday. It is modeled after a sphere making machine the rock hounds use to make spheres from rock.

    To try and keep costs down I got three old drill motors for cheap at an auction. I polished my first ball yesterday and I did the polish without a proper polishing medium. Once I get the right polishing grit sorted out, I think I will be able to get a crappy looking ball to shine up in about 15 minutes.

    Here is a youtube vid of someone's marble machine in action.

    At $1/ball, how long until that contraption pays for itself?

    Is enough material removed to change the diameter?

    Kudos on the interesting contraption, but...

    Quoted from jwilson:

    I have about $25.00 tied up. Not counting my time, of course. I currently have 4 pins working with 9 balls installed. If it proves to work like it is supposed to and I rotate the balls every three months, it will pay for itself in less than one year.

    I have only polished one ball to try it out. I mixed up some Brasso metal polish, some Comet sink cleaner and some antifreeze as a polishing medium. It took about an hour to polish most of the cut marks off the ball surface. I need to find a different grit media for polishing a little faster.

    I'll have to try it out for awhile to see how many times I can polish a ball before the ball can't be used anymore. One thing I am confident of is that it will never put a ball in an out-of-round condition. So far, I am happy with the way it performed yesterday.

    #281 2 years ago

    I like the creativity a lot. Can you post some close ups of the balls before and after? I'd be interested in seeing if you can get the balls to new. Have you tried some more heavily pitted balls? This will tall you how much is actually removed.

    #282 2 years ago

    I'd like to see a dial calliper measurement of the ball after this polishing!

    Yes. I think this iPhone will let me take good before/after closeups. I don't let my balls get heavily pitted. At most, they just get the light scratches and cuts. But what I might try for an extreme demo would be to drop a ball on my patio bricks a few times. I had a ball fly out of my buffing fixture and hit the bricks; I had to throw that one away.

    I have been hand buffing and polishing them a few times now and I can work them to get them to "like new" appearance. But I question in my mind if getting them back to "like new" is necessary. I wonder if just polishing a ball enough to remove the high points of a scratch is all that is needed.

    Quoted from jwilson:

    I'd like to see a dial calliper measurement of the ball after this polishing!

    Good idea. I have a pair of calipers and a supply of new balls to make some baseline measurements and do the before/after comparison.

    I think I have found a rock polish shop where I can buy 1000 grit polishing powder for cheap. But I need to get them on the phone and ask some questions as to what will work best. The shop also has some very fine polishing powder but the price per pound is a bit more.

    I'm leaving town tomorrow. It will a couple of weeks before I can get back to this.

    I don't think necessarily what this thread had in mnd, but here is a router template I made to route the groove in shooter lane for my homebrew playfield. I used a 1" diameter round nose router bit for this, and the taper is set with the blocks on the bottom to match my 70s Gottlieb machines. simply clamped to the playfield and the bit set so it doesn't quite touch the playfield at the top end.

    I'm back with some before/after pics of a couple of silver balls I ran through my polishing contraption I found a lapidary supply house and bought one pound of 1000 grit polishing media.

    I ran two balls through the polisher for 25 minutes. They cleaned up nice and came out smooth but the 1000 grit does not make them shine so I had to finish up with about a minute's time on the polishing wheel.

    A new ball measured 1 1/16" which is 1.0625 with digital calipers. After smoothing them up and polishing they measured 1.059 for a loss in diameter of .0035, or three and one half thousandths. At that loss rate I could polish a ball five times and the loss would amount to 1/64". I don't think losing 1/64" inch in diameter would hurt game play but I have no way of knowing for sure except for trying this for awhile.

    I may be rationalizing but, so far, I am happy with the results. If I can make a ball live for five times that gets the ball cost down to an equivalent of 20 cents.

    Here is a pic of the machine, again.

    1fdc67c9aa8328bc33c43ef254f249eac778e71c (resized).jpg

    In this picture, both balls had about the same amount of surfaces scratches when starting out. This pic shows the right hand ball after it went through polishing procedure. The ball on the left has not been worked, yet. I wish I could get you better pics but this is as good as an iPhone 4S will do.

    IMG_3910 (resized).JPG

    In these two pics, the left hand ball has now been through the polishing routine. It is nice and shiny and will not tear my play fields up.

    I can live with this. I load a ball into the machine, go some other things, come back 20-30 minutes later and repeat the process. For not too much effort I can keep an inventory of silver balls for cheap.

    I would prefer to have some different motors to replace the drill motors I am using but motors are not cheap. I think the ideal motors for this would be windshield wiper motors as they are durable, quiet, and continuous duty motors, but the salvage yards around here all want $20.00 per motor, plus you would also need a transducer.
