OK, I had another idea. What I did was cover the glass touch screen in foil as per the thread by turbocad and think that everything fits well expect the one side that is curved. At this point, I should be able to just build up that side with some more filler and sand it down, right? Attaching a pic to illustrate...
Also, since the Dynatron 660 is no longer available and I have already used it on this, what would be a good alternative that would be hard for a good base?
Another oversight, 'Cad taped the inside edge of the monitor bezel to keep it clean and straight, and he built on top of it. The glass attaches to the flat (made for the glass) bezel it cam with.
Now you don't have a bezel that came with the glass, so this is why you have to create a FLAT "picture frame" aka bezel that the glass will later be secured to the back of.
That picture frame gets attached to the back of the factory plastic bezel you're trying to add material to.
once the two pieces are joined, via CA glue, epoxy, whatever,.. you then use the Dynatron or filler of your choosing to create a smooth transition between the inside edge of the "picture frame" and the factory plastic opening.
Being that you are adding material to the factory plastic itself, you don't need to put foil on anything. If anything you might tape of the inside edge of the "picture frame" you make in order to keep the edge nice on sharp.
Maybe these images will further clarify.
factory bez backside
monitor frame / "pic frame" - make this out of plexi, acrylic, wood, aluminum, whatever
attach frame to backside of factory bezel
attach frame to backside of factory bezel - front view
fill the difference with "filler" in order to create a smooth transition between the factory material and the "pic frame" edge.
Not sure how else to describe the process.
Ok, I started with the right idea, but looks like I used a flimsy bezel, #1, and then molded it to the dash peice instead of the hard frame. Do you think I can fix what I have by just making the wooden frame for the glass and attaching that to what I have now, or am I going to have to completely start over?
If you can get a spare bezel or two, definitely start over. I did a similar thing with my bezel and after ruining it (it became too flimsy after too much trimming down & it warped severely from the solvents I was using). Lilliput doesn't make spare bezels, so I was SOL. I've now found a way to create one from scratch (ABS sheets) and that's the stage of my fabrication I am currently stuck on.
