1440 lathe tools suggestions

One of the things I like about the 5C chuck is the smooth nose. When working on very small things very close to the chuck & using a file or abrasives there are fewer risks.
Both of my collet chucks are of the "Set-True" variety. Very desirable when you are doing series work and need to reverse the work in the chuck.
A big advantage of collets over jaws is hot marring the work, even if it is threads.

I went out to the shop and looked at some of my collets. I have rubberflex collets that start at 1/16 dia go up too 1 3/8 dia.
I have full set of Hardinge hex and square 5c collets.
Metric set 3 to 25 mm.
about a hundred 5c collets with lever collet closer
about seventy 2j collets with closer.
and about 20 5c step collets to hold large or special shapes.
also have expanding 5c collets to hold on bores and the like.
I been machining for almost 70 years so I have a large collection.

All the collets in first pic show shapes that have been held in a 5c spindle.
Most of these shapes could not be held in a er40 collet. One of collets in bottom row is excentric. I used to run excentric cams held in 5c collets0in production runs like the cams used in KDK tool holders.

just my opinion, but for small parts and precision work, you might invest in some cobalt HSS tooling. If you are very shy about sharpening and have the money you can start with AR Warner inserts and tools. They are high speed T15 quality, and can take very precise shallow cuts with very little pressure (deflection). This is a great advantage when making *small* parts...

Lots to absorb here......

What size is your post ? I have some CXAs here that can go as soon as I get up to speed .

CXA sized.

I see Jim recommended 5C collet chuck. You should have a look at the attached first - I prefer ER40 but there are trade offs to consider.

This would be a good starter carbide set

Then I would get a 5C collet chuck for small parts. And buy a few more wedge tool holders.

5C or ER40, how will they attach to my lathe? Here are photos of my 4 jaw chuck and face plate for reference.

You appear to have a D1-3 or D1-4 headstock (they both have 3 pins). You can find out which by measuring the centre to centre distance between the pins. All of the dimensions are easily found in charts online.

You can then order a collet chick that will fit your headstock.

5C or ER40, how will they attach to my lathe?

You have a cam lock machine spindle. Do like Dabbler said to see which.
Like has been said both systems have advantages and disadvantages. I've got both and will always go to the 5C for small parts especially with short holding. But you need collets by 64ths! ER40 will hold over a wider range but I've found that even though they will close on the work they may not hold well at the extreme of their closing range. They also don't like very short engagement of the work. Whichever one you get, get the "Set-True" type so you can adjust precisely on center when reversing the work. Collets are nice when you want to hold a threaded end.

I would get one of these toolholders for your tool selection.
They are extremely versatile and can be used for:
O/D turning
Profiling
Grooving
Parting
Threading
Radius grooves

There are several brands to choose from not just Seco.

What a great site here, so many helpful people here.
