This is the coolest thing. Fixing broken/missing plastic with baking soda and super glue.
I have used this professionally. Very durable. https://www.bonanza.com/listings/Rawn-35105-Plas-T-Pair-Plastic-Repair-Kit-M... On Mon, Sep 23, 2019 at 4:19 PM corey cohen via vcf-midatlantic < vcf-midatlantic@lists.vcfed.org> wrote:
The video referenced, is a bit long and repetitive. Here's the short version. Materials needed: Baking soda and presumably generic superglue (cyanoacrylate) and some aluminum foil taped to a surface. Of course, a broken plastic part. You'll need some very small files. The goal is to build up material on the broken part, to shape by filing with a file, into the desired shape for repair. The "desired shape" may be determined by comparison with an unbroken part. The aluminum foil, is a convenient non-absorbant and disposable surface. The baking soda provides some bulk for the glue and may help accelerate the glue to dry. Instructions: You have a part with a broken tip or point or area. Plan in some fashion, the shape and size of the new repair. Get some superglue and a teaspoon's worth of baking soda. use aluminum foil as a working surface tape the aluminum foil to your workspace table. dump some baking soda on the foil. dump ELSEWHERE on the foil, a glob of superglue repeat the following quickly (less than a second) dip the broken surface lightly into the superglue blob. dip the wetted surface lightly into the pile of baking soda. repeat that many times, to form a blob of hardened superglue/powder.

Why not just use some bondo? -andy

Bondo doesn't set as quickly, and if not mixed properly, won't set correctly. Besides, Bondo gets warm while it cures and may not be good for the plastic when it does. On Wed, Sep 25, 2019, 5:28 PM andy diller via vcf-midatlantic < vcf-midatlantic@lists.vcfed.org> wrote:

JB KWIK EPOXY sets very quickly But is very hard And can be molded with a Dremel using the correct bits! Sent from: My extremely complicated, hand held electronic device.
