We have recently acquired a Case 8830, same as Hesston 8200, that some of the glass has fallen out of. We have all but one window which I think we can find still. I have heard that the glass falling out of these is a pretty common issue on these. I want to re-glue these back in place, but am afraid they will fall out again. What would be the best thing to do for these once I have them glued in? I want to try to not do anything ugly. Maybe thinking about making some irons that will line up with the inside window frame that I can drill. If I do this does anyone have a good method to drilling the glass that won’t shatter it? Any other ideas that would be better?
