Help required identifying taper
(OP)
Could someone please help me identifying a taper:
Small diameter: 0.430"
Large diameter: 0.465"
Length: 0.55"
I have googled and searched this site but all to no avail.
The taper is on an air-powered tapper and I'm trying to get a replacement chuck. (Possibly Ingersol-Rand, but it's so old there are no markings on it. The old chuck was Swedish : Maskin AB, but I cannot find any information about it on the internet either.
Any help would be appreciated.

RE: Help required identifying taper
In this case it is .063636... inches/inch=(.063636...mm/mm). Unfortunately this does not compare closely with any standard taper listed in Machinery's Handbook. It might be a special taper in which case you might have to make it or have it made special. Another possibility is that your measurement is inaccurate.
RE: Help required identifying taper
The measurements are probably not too accurate, but close enough that the taper seems like no standard one, at least that I can find.
Oh well, guess it's time to crank up the lathe!
Thanks again, metman.

I also took a look and didn't find anything to come near the dimensions you gave.
Think you will have to make it yourself.
Mention that the Swedish word "MASKIN" means machine in English.

The parts are still on my desk waiting for me to sort this out. (Hangs head in shame and mutters something about being really busy...)
Actually, I've decided to keep the old taped and adapt the old holder to take a new chuck.
It'll look odd, but be easier to machine. When I get around to it...
