I have yet to use this idea for a repair but have spent some time playing around such that it seems one could take advantage of this idea.

Spread your super glue in a dint in something then sprinkle on some baking powder ... Sets fast and very strong.

I tried this fix once but the dog kept licking the telescope so I had to scrape it off.... :sadeyes:

I have never heard of that one. Now I will have to go and look it up.

Must be a big toolkit to fit both scope and dog in...:D and the scraping off of dogs...is that an act of cruelty or kindness?

Baking soda? Why?
Would any other powdered substance do the same trick? Or not?

I did a little searching. it seems that baking soda will act as an accelerator for the glue, making the chemical reaction to set it happen faster and also gives extra body/bulk to glue.

About halfway down this page.

Could be useful ... who needs a 3D printer when you can just raid the kitchen for baking soda ..

Can you use the old baking soda that's been sitting (deodorising) in the fridge for a year or so, or does it need to be fresh?

Experiment but I would think it should work...I do wonder if cold if reaction would be slower...

If you want the superglue to fill small gaps, like an imperfect crack (doesn't fit together perfectly), I would suggest the gel variety for any important repairs. Loctite is an excellent brand. They also make an accelerator/primer which makes for a very quick bond, esp. useful in manufacturing, not that it isn't fast enough already. Store at low temp / refrigerate to increase its shelf life.
