Acrifix© has a very low viscosity cement for Plexiglas under the name Acrifix 1s 0117. The trick is to use a syringe with a needle to apply the glue.
Another way is to dissolve acrylic powder (saw dust) in chloroform or a less ‘suspect’ solvent to make your own glue and after fixing apply a little chloroform by a syringe along the seam. Anyhow, it is important to use a cement that offers the same refractive index as the material you use. eric Van: [email protected] [mailto:[email protected]] Namens gregebert Verzonden: vrijdag 13 januari 2017 0:00 Aan: neonixie-l Onderwerp: Re: [neonixie-l] Re: Small run fabrication If you use clear acrylic, it's tricky to get a perfect cemented joint with no visible air bubbles. The few times I tried this, I used excess cement and had to spend extra time buffing-out the areas where the cement evaporated. If the joint was in an area that wasn't visible, I just left the bubbles/smudges. I never attempted to polish a cut surface and cement it; I only bonded the 'native' surfaces that are perfectly smooth. Surprisingly, it's rather easy to gently heat acrylic and bend it to-shape. Years ago I made my own fish tank, and there was minimal distortion, no cracking, and no bubbling at the bend regions. It was clear acrylic, and I didn't even need to buff it. Also, if you need to sand-down edges, joints, etc, they will buff-out very nicely if you are patient. A buffed surface will never appear exactly like the native surface, but it will be very close. Even properly cemented seams will be invisible with enough sanding/buffing. Reflections from a distant light source are the best way to assess the surface smoothness. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
