Autosteve Posted August 1, 2017 Share Posted August 1, 2017 I have a couple of problems to overcome with this idea and I'm interested if anyone has any ideas. I need to put some post bolts through the glass, not in the direct path of the balls, on the sides of the glass to hold the balls from falling off so not balls will be hitting and stopping dead. What is a good way to insulate the metal post bolts from the glass?. There will be no bumpers, flippers or mechs of any type on the glass section of the playfield. I need to attach the glass section of the playfield to a wooden section as in to the end of the playfield to mount the flipper mechs too. Any ideas how to do this?. I'm thinking silicon myself. And lastly, if the glass is 6mm, what type of glass would be suitable for such an application?. The size of the glass will be roughly half the length of a playfield by 150mm. I'm not interested in using any type of plastic because plastic just doesn't remain clear for long with a ball rolling over it. Link to comment Share on other sites More sharing options...
Boof Head Posted August 1, 2017 Share Posted August 1, 2017 Rubber grommets work for the post and glass situation? Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Michi Posted August 1, 2017 Share Posted August 1, 2017 Clear silicon grommets should work. Not as visually intrusive as rubber, and they should last a while, too. I would strongly recommend tempered glass. As far as I know, it's impossible to cut or drill tempered glass, so you need to get your glass cut and drilled and have it tempered once you are happy with the dimensions and locations of any holes. If you are going half a playfield, the same thickness as a normal pinball cover glass (4 mm?) would work. Tempered glass is insanely strong, as long as you do not have impacts against the edges or corners. (Those are deadly, even quite minor ones.) Depending on the look you want, 6 mm might look better but, in terms of strength, 4 mm should be fine. Michi. Link to comment Share on other sites More sharing options...
razorsedge Posted August 1, 2017 Share Posted August 1, 2017 You could also use some form of gasket material if you would like a more rigid result ... ? Like a soft washer. If they are tight there should be no need for cussion going through the hole... ? Link to comment Share on other sites More sharing options...
Whitewater Posted December 8, 2017 Share Posted December 8, 2017 I also was thinking of using glass, have you got any pictures you are willing to share ?

BIG Trev Posted December 8, 2017 Share Posted December 8, 2017 I've asked my Mrs as she used to sell glass fittings and she recommends using silicone tubing over the screw where it passes through the glass, the metal screw should not be in contact with the glass at any point. She also said using toughened glass is a must. Cheers Trev Sent from my SM-G930F using Tapatalk Link to comment Share on other sites More sharing options...
metalthrashinmad Posted March 11, 2018 Share Posted March 11, 2018 Toughened glass is definately much stronger. However, the tempering process makes it loads more susceptible to scratching. Unlike plastic, you will never polish scratches out of toughened glass. Just something to keep in mind. Good luck with the idea.

blue95 Posted March 14, 2018 Share Posted March 14, 2018 The WPT mini playfields don't seem to scratch up heaps, they're some sort of plastic Link to comment Share on other sites More sharing options...
wingmaster Posted March 18, 2018 Share Posted March 18, 2018 Why not use plexi glass (acryllic) ? Used in multiple pinball machines as playfield. It is very easy to drill and cut. You can wax it to prevent any damages. Link to comment Share on other sites More sharing options...
