hi all, The lathe i have came with a home made tool post that holds 4 toolbits at once. however to change between the 4 bits you have to turn the tool post round and some how get it back square i presume (im a complete newbie).? there are 4 allen head bolts holding the tool bit in so i assume i would have to undo those and reset everything up if i wanted a different bit. ?
?
All this to say what quick change toolpost with the dovetail holders would work and is it worth spending a couple of hundred pounds?? ?
?
many thanks

here are some pics of the home made tool post as requested

I put an AXA clone on my TH42 some years ago. Works well.
Got mine from Amazon for $130, but they've gone up in price since then. By quite a bit.?

I second this.? I got a Phase-II brand clone of the Aloris-style
toolpost, and it was a HUGE improvement in both rigidity and
repeatability.? You could take the tool (with the holder) off,
swap to another tool, and then put it back exactly.
These come in wedge and piston styles.? I had the piston style
one on my Atlas, and it was fine.? I now have a wedge style on my
15" Sheldon lathe, and it is fine, too.? Usually the wedge types
are more expensive.

Mine is the wedge style, as that was what my school was using on their larger lathes, though BXA & CXA sizes. I'm told the piston style doesn't grip as well, but you couldn't prove it by me.?
It is a good idea to also have the lantern or American style tool post and an assortment of toolholders for that, as well. They will do things the AXA style won't do as well, and the AXA style does some things the lantern style doesn't? do as well. I can't see where having a 4-way block tool holder would hurt anything, either. :)?
Of course, I'm? a toolohaulic, so might not be the best model...

I started out with a "rocker" style tool post.? It work but would often catch the bit and move it off center.? When I managed to get one of the 4 sided posts, I thot it was a wonder.? But after a while, it got very tiresome to put a bit in and shim it to the right height, and for each bit having to do this. Putting "4" bits in at once usually did not work.
When I managed to get hold of the Aloris style tool post I was simply amazed at how well it work, how easy it was to change a tool--and it was pre-set to the right height.? The only problem was having a separate holder for each tool.??
Well . . . .? There is a solution--you can make one.? Or you could buy a cheapo Chinese one.? That's what I would do.? Look into Shars in the USA, but you were talking Lbs not USD so most likely your are in Britain.? I'm sure there must be a cheapo sales company in Britain.? If it were me, and I had access to milling capability, I would make one--lots of fun to make your own tools.? After all, that's what machining is:? Making a tool to make a tool to make a final piece.? Done it many times.
I bought a bundle of the slide on tool holders but as every machinist knows, you never have enough tools, so I will get around to making more.? I have a good supply of the right type of steel for making the holders.

thanks for the replies

@ Bill unfortunately the original lantern style post got lost years ago i assume and being in the uk trying to source one on ebay etc is expensive by the time postage is factored in.

@ Ion thanks i will see if i can source one of those over here

How about buying a milling attachment for your lathe, then you can make your own holders.? As you stated, that is what a machinist would DO.

I think the Myford style post would work well the 10" Atlas.

A machinist would not be able to buy the steel for the AXA tool holders, for the price of buying them ready made. You would also need to buy the set screws, the long screw, and the two height stop knobs. And the commercial ones are also heat treated (well,
some of them, anyway).?
Go to eBay and buy your tool bit holders for 10-12 bucks a pop and rejoyce.?

??? All of the 4 ways like in yer pic? that I have seen &
used have? ball detentes in the bottom so the tool post moves in
increments & is it's square on one side if ya use the
detentes?? , ya may flip yers over & see if it's missing the
ball & spring or if it even had one . It should be square for
the other 3 sides . If ya have a 123 block , squaring up the tool
post is a breeze . I just put it between the tool post & chuck
& run the carriage up with the tool pose slightly loose , it
will square itself & then ya tighten the tool post . My QCTP
is a wedge type & I got it at either CDCO tools or CME tools ,
good quality & the price was good . With ya being over the
pond I'm guessing that freight will be a matter . I have bought
from Chronos in the past , I know they have them .

Even so, it's still very fun to make the parts.? Also, you don't REALLY need the best steel for this project.

True that, but you can make one of them, yourself, too. Probably easier to make a Van Norman style QCTP. Check out one (or all) of the Mini-lathe groups. The QTCPs for the 7x?? Mini-lathes are a bit small for the Atlas 10" lathes, but can be scaled up fairly easily. Or just blocked up to center height.?

How about making a milling attachment for your own lathe? Or making/buying a milling machine...
OK. Yes, my addiction is showing!

Ah, I had never heard of?Van Norman style QCTP so I chekt it out online.? Yes, definitely would be easier to make than an Aloris style QCTP--however,? the ability to change quickly tools, is hindered by that tightening bolt.? Also, the tool holder itself (many of them) would eat up a lot of metal and a lot of time.? In making an Aloris style tool holder (not the post), you can make several in one go then cut them up .? There is more initial work on an Aloris style but the benefits IMNSHO (in my not so humble opinion) FAR outweigh that extra work.? Besides, most of the work is simple drilling and tapping.? Cutting the bevels is the part that is hardest because of the precision needed and the possibility of breaking a couple bevel cutters.

The major advantage to the Van Norman style QCTP? is that it can be made on the lathe. No milling machine? or even milling attachment required. Useful, yes, but not required. ;)
The Aloris style is quite complicated, and requires a well-equipped shop & a skilled metalworker. I'm closer to that now than I was in 2015...

YA can also buy the tool post without the tool holders from some
places & they make the tool holders . What ever ya do its
gonna cost $ or material or both .

Can someone tell this newbie what a "Van Norman style" vs an ALoris style and an AXA is?? I am just starting to look into this subject and wondering where I can find a short, concise, and factual comparison to what to look for.? Thanks!

Google is your friend here, just highlight? [Norman style vs an ALoris style] from your message and add the word toolpost and then search for images. Pictures def worth a thousand words in this case. There is some confusion in that the Norman patent toolpost and the Van Norman milling machine company sound the same, but are different things. Aloris toolposts?come in different sizes for different sized lathes, denoted OXA, AXA, BXA, CXA. All the knockoffs stick with that nomenclature.
