We do seem to have endless debates and opinions expressed about CA and other finishes. Nothing wrong with that, but opinion is opinion and nothing more.
Here are some facts about CA which are intended to be helpful. Please feel free to correct me if any of them are wrong (but not just because they do not align with your opinion).
CA, if applied correctly puts a thin coat of acrylic material over the wooden substrate, it achieves a high gloss in a similar way to that by which French polish achieves a high gloss on grand pianos; by covering the wood with a thin coat of finish which can then be burnished.
CA is a very robust finish which will stand up to wear better than many other finishes.
CA is not the only way of achieving a high gloss finish.
CA is not the only way of achieving a hard wearing finish.
How you apply CA is of little consequence so long as you achieve an even coat.
How many coats you need to apply depends on the thickness of each application, how much of it you sand off again between applications and how thick a finish you want to achieve. Three coats can achieve a high gloss, so can ten.
Some people like to use CA with BLO. I don't. If it works for you then use it.
The fumes from CA are toxic and contain cyanide gas. This will only harm you if you breathe it in.
Woodworking respirators will not protect you from CA fumes they will draw the fumes in.
You can buy face masks that are rated for chemical fumes.
An extractor will draw the fumes away but make sure the exhaust from it is directed well away from you.
And now a suggestion:
One way of avoiding getting CA on the bushings is to take the blank off the mandrel and finish it between centres:
