Old Lathe question

[Voodoochikin04]

if they are close enough to have to use exacting measurements to show the difference, then the picture does nothing!!!!  what are the differences according to you?

What happened to this?

dont worry, ill ignore your threads from now on jerk

I'll throw ya a bone anyway.  A common setup would be something like an mt3 to a Jt3.  The MT is about 3X longer than the JT.  Just like in the picture.

Since I'm showing my ignorance
The Morse looks familliar from my drill press, But where are the rest commonly found?
Inquireing minds want to know

[Boostinjdm]

Morse and Jacobs are prolly the ones most people will see.  Jacobs is as far as I know is only found in drill chucks.  Morse is also most common for drilling.  Chuck adapters (like the pic)  and drillbits, so you you don't need a chuck.  Most tapers that I have found info on were developed by the machine company that needed them.  There is not one "standard" that everyone goes by.

Now were getting somewhere...
I know that most drills use a Jacobs chuck...
But for most of us that is as far as we know

Google my friends, I use it every day...

Google don't work?
Here ya go.

Actually, that top picture is not Bridgeport, It is R8 to Jt...

Additionally the bridgeport IMO is and should not be used as the term for that shank. It is technically an R8.

The first Bridgeport I owned actually used quick locks.

Ill take some pics at work on Moday of all the diferent tooling shanks and holders we use. Pictures always are a great refrence! thats why I like to post up so much of them.
