content: Down below you will see picture of where used to be handle and hande itself. Recently I have been usign my oven but broke switching handle. This handle is now almost cracked in half and don't know what glue to use to bond broken parts together. I have instant "Superglue" and "All purpose contact adhesive". Then by looking on first picture, I will probably need to use silicone before I cram switching handle back into frame?

content: Personally I would use Epoxy Resin, Superglue is not good at filing spaces and I am not sure contact adhesive would stand the heat. If you closed the thing in a soft jawed vice and filled the broken area with some it should last a good while.

content: New handles here are $2 each, in whatever size. Otherwise 2 part epoxy ( white or the grey metal type, not the clear) works very well to bond it back together. Clean thoroughly with a solvent like acetone or thinners before using the epoxy. Did you lose the little carbon steel spring as well? If so when the handle is cured epoxy it back on to the shaft, but only wipe the shaft down and leave a 2mm gap so it can turn.

content: You may be able to fix this with Superglue, unless the knob heats up during use.Clamp the knob closed.Wrap some sewing thread or other sort of thin string tightly around the collar. Maybe 6 or 12 loops then tie off the thread.Apply Superglue all around the thread.Allow glue to dry and maybe apply a 2nd coat of glue (or thread and glue)Epoxy would work at least as well as Superglue, starting with a thin epoxy coat before the 1st layer of thread would be ideal.The Thread by itself would never be tight enough and would stretch over time, Superglue alone would crack. Combined, the glue stops the thread from stretching and fills any small gaps while the tread helps stop the glue cracking and takes up the slack even if the glue does crack.

content: @ecat Interesting suggestion. Thanks.Quote from: Hypernova on April 21, 2013, 02:02:56 pmAre these knobs universal?

content: If the handle is made of abs you can fuse the broken parts together with acetone.

content: It will be Bakelite or another glass filled thermoplastic, and yes, they are pretty universal, being available in 2 sizes, 6mm and 8mm, with only a few cosmetic differences like a series of numbers from 0-10, 0-6 or 0-400C and a grill indication on them. They are cheap, common and always available in every size and scheme other than the exact one you want just now. I just get the nearest.
