[sdiy] Synth Panel Window Adhesive

[Mike Bryant]

Just remembered the glueless approach we used at HP decades ago.

Make the lip much bigger on two sides and have four countersunk holes and threaded inserts on the PCB behind, so the perspex is part of the whole PCB assembly offered up to the front panel.  For high volumes best to use a jig so that the perspex is aligned correctly before you offer it up.

I get the perspex made with a lip on all four sides, then apply a thin film of epoxy all around and push into the whole.  But even with a protective film, if you get the epoxy leaking onto the visible area the window is scrap.

Hi Synth-DIYers!

I have a question that might be a little bit OT, but I was wondering, for those of you that have built synth panels with perspex / acrylic windows, what did you use to hold the window in place, and how well did it work?

I've built a few things now that used 7-segment style LED displays, and I've put rectangular holes in their powder coated metal panels, laser cut some tinted perspex to size and tried things like pressure fitting (too easily dislodged, or broken while being pushed in) and glues, which are a bit messy and hard to avoid having some of the glue showing up on the front panel...

I'd love to hear your experience and any solutions you may have found!
