I'm in the middle of fixing up a Gottlieb Roller Disco Pinball machine. I just recieved my new rubber bumpers and blubs.. During my cleaning I found the two broken plastic that I thought were long gone. I can't find any replacement plastic parts any where, so I want to try to glue them back together. Thats why I asking this question before trying to glue them up.. I was thinking of a model cement like Testers? I know that more times then not super glue won't work on plastics.. Has anyone has been able to glue any broken parts together and have them hold??

Thanks Gary

A little superglue I would guess. But just a suggestion. If you can't get a replacement, buy a piece of plexiglass and cut out the shape. Next make a photocopy of the existing plastic. Use photoshop to clean up the graphics and print it out. Next use a thin sheet of lexan under the printed graphic to sandwitch it between the plexiglass. I made all new plastics for my "custom" Space Invaders doing that.   

Here is a link on another way to do it.

glue will not work

super glue Will work   then put on clear fender washers we done it 100,s of times with glue you have nothing to lose

I did the photo shop thing and fixed the broken plastics on my computer. The problem I'm now running into is getting my computer and printer to print out the repair the correct size and color. The colors are perfect on my computers screen, but look washed out when printed. Also the size of the repair being printed out is about 3/16 smaller the the original I scanned in?? The project is on hold right now..

Super glue will make it go white and look UGLY! It may glue it but it will look horrible...

Hey Gary, Try resizing the image with your paintshop program until you get the size correct then run it thru your printer a couple of times. (wait for each coat to dry)
Use clear plastic sheet stock used to print for an opaic projector and print mirror image. Then cut out the image and invert it so the shiny side is out. I've done this several times with pretty good results using a epson printer. Epson's ink is water resistant. 

You should check also the settings at the print dialog. It matters what paper you used, what is the 'quality' settings at your printer and if there is something like 'scale to fit' at your printer's settings effecting the size of the print.

here is a down and dirty trick that you might try....buy some transparent mylar or maybe even clear shipping tape.  Tape the underside....it will hold the pieces together, and won't be visible....the post screws will hold it together.....

For clear plastic, I am not sure. But for a white or black piece (broken, or missing part) try plastex. get a kit with a modeling bar so you can duplicate an existing part, and then put it together. I have used it on multiple broken tabs on connectors
