I use taper pins whenever I can. My projects are all small-medium, so I use mainly #3 pins. I like to make a punch mark on the work piece that takes the small end, so I can remember which end to drive it out.
Good info. Have run into these a bit recently on some old lathes at the plant I work at. Some of the guys don’t know they’re tapered pins and put roll pins in their place. It can be a mess.
The shear pin on the leads crew was often replaced at the training schools. With students crashing into the chuck Something that all users or owners must find ways to aviod. Could be difference between employment & unemployment. Locking shafts together as you say mistro, many applications.
Love taper pins, anyone who doesn't just hasnt learned how to work with them and understand them. Im a gunsmith and use them frequently. But I also get someone almost once a week that doesnt understand the taper pin and doesnt bother to look at both sides to see if one is smaller than the other and cant figure out how to get them out. Or if they get lucky and get them out they cant figure out how to get them back in 🤣 Cant fix some people
Isn’t there two sizes? Morse and Brown & Sharpe? Think I ran into this when I was drilling door handles on a CRJ200 for taper pins. Had the wrong taper angle.
Morse & Brown and Sharp are tooling taper used for mill cutter drill bits & 'c, Brown & sharp is pretty much obsolete. The standard American taper tins are all standard, the British standard uses the same 1/4" per foot taper, but come in slightly different sizes, the same sizes are available in either system but they use different numbers for description. A metric standard also exists, that is .0016" size variation at 50mm, or .010" variation per foot, these would interchange in most cases without harm. I have also seen several proprietary tapers on special, or sensitive equipment, planes, expensive brands, medical stuff...
Dry Air. I have not found a good solution for keeping rust away when the air is damp, warm dry building, and a lite coat of oil is best. The tools that I do store in dry non-heated space get some rust on them. Actually painting the tool is best I have found, some gear oils work fair, the hot dip coating don't work.

This is better than TV

7 degrees. I think that’s the taper on them

What ever did you do to fix the Big asphalt grinder…?!!
We're still working on it. More videos soon!
Look like McMaster Carr bags
What can you coat the giant reamers and other lesser used tooling in to keep them rust free over long periods of time?

You won't believe me, but I know a guy who can drive these out both ways. The same guy who can create endless left-hand threads with a right-hand tap.
Clown 🤡
Life as a machine tech would have been a lot easier if people hadn't tried to drive them the wrong way. Seem to remember ⅛" per foot is the taper
