Topic tags/keywords: turning lathe question

I’ve seen a number of references to using cyano glue mostly by pen turners, here and elsewhere.
Why are you using cyano, when do you use it, and how do you apply it? These questions are assuming it’s more than just for gluing. Finishing?

In response to pen turning.

Why: Because it sets immediately and you can turn the pen right away.

When: Used to secure brass tube in wood. Also, it can be uses to stababilize soft items such as spalted wood, antler, etc. It can be used to fill defects or voids or boo boos by packing sawdust in the defect and flooding with CA

How: You use sandpaper to rough up the tubes, and inser the tubes in wooden blanks. Use accelerator to set glue.

It’s widely used in guitar-making. If you start bending
ebony and other brittle woods on a hot iron you’ll
figure out real quick why CA is so great – it saves a
lot of guitar parts from the scrap bin.

I use epoxy to glue the brass tubes. I use the CA for my finish. I put 5 drops onto a paper towel and apply that to the spinning blank. I then drop a little BLO onto the paper towel and apply that to accelerate CA to cure. a little sand paper takes out any highspots after appling six or so coats.

When I get cut carving, I use CA glue to seal the wound. What bothers me when I draw blood is that I cannot continue what I’m doing not that it hurts a little. The US army experimented with CA like glues in 1950-60 and the modern glue surgeons apply over wounds is a CA like glue. The regular CA glue might be mildly toxic so it is not for everyone.

CA was originally made, I’ve heard, as a wound treatment. It works very well. Liquid bandaid is a commercially avalable version for just that. I’ve used regular CA and take it camping with me ‘just in case’.
I use Ca sometimes for mounting tubes in pen blanks and sometimes in finishing pens. It gives a very durable finish. Some people don’t care for it as it can look ‘plastic-y’. something for everyone, right?

I recently dovetailed some drawers out of China 1/2” ply, I saturated the ends with thin CA, it keeps the cheap ply from chipping out.
I also use thin CA to harden threads when I tap wood.
