Does anyone still use lantern toolposts
I was just wondering if anyone who has a lathe capable of using a
quick change toolpost like Aloris, would still have any reason to ever need a lantern toolpost. My feeling on this matter, without knowing too much, is that lantern toolposts are obsolete and quick change is the way to go, and there is never a reason to use these old style tools. Would there be anyone who disagrees with this. i |

Most everyone should agree I think. The last issue of Home Shop Machinist had an article about tool
posts. Bob Swinney "Ignoramus14738" wrote in message ...

They are almost as rigid as a one-piece tool block, and they are quicker and of course easy to index. But there are times where you have to work in a tight area for which they are simply too large. That's where the lantern toolpost becomes necessary. Use your lathe for a while. Eventually, you'll be glad you have the lantern toolpost. John Martin |

My feeling on this matter, without knowing too much, is that lantern toolposts are obsolete and quick change is the way to go, and there is never a reason to use these old style tools. Would there be anyone who disagrees with this. i I've encountered a very few setups where the small size of the lantern post helped. I use a Multifix toolpost http://picasaweb.google.com/KB1DAL/H...33382447691698 that allows the tool to rotate in 9 degree steps, almost as freely as a lantern post. It lets me position a hand-ground HSS bit to both turn a diameter and face a shoulder, using either a straight or an angled Armstrong holder or directly in the QC block. On my lathe there is a range of workpiece lengths where the carriage doesn't have much travel between the head and tailstocks when the work is held by both a collet and the tailstock center. The tailstock spindle is a replacement and wobbles if extended out very far. Typically on these small parts I need to lean in close with a magnifier and don't want spinning chuck jaws nearby. I have 3" and 4" Enco/HF/Sherline chucks but they aren't as precise or rigid as collets and often don't let me move the work back and forth between the lathe and an indexer in the mill. In these cases a lantern post would be useful if I didn't have the Multifix. I didn't show turning tool examples when Bob Lalonde asked because the way I grind them doesn't work so well in a non-rotating Aloris type tool post. They look like threading bits but blunter, 70 - 80 degrees included angle. This shape doesn't requires much grinding from the original square end, and is easy to resharpen. It's about the right shape for a bent toolholder if you watch the angles. Original Swiss Multifix tool posts are very expensive and Enco seems to have discontinued them. I bought some extra Chinese (?) tool holders from Tools4cheap http://www.tools4cheap.net/proddetail.php?prod=40posa1 that fit fine and are well made. If they were priced more competitively I think they would be popular. I've wished I had the versatility of my home setup a few times when running a CNC lathe with a Dorian toolpost and indexable carbide, but always could do the job. jsw |

I sure would NOT want to go back to the lanturn post for most work. However, I sometimes find myself having to work into odd corners or recesses that cannot be easily reached with standard quick change tooling. I've made special quick-change tool-holders for some of these situations, but even then, the problem arises. It's often quicker to switch to the lantern toolpost than make a new toolholder, or custom grind a special tool bit for some oddball one-off application. Note that I already have a HUGE collection of odd custom toolbits and "Armstrong" style tool holders with various angles to choose from. Thus some one of these is probably very close to what I need for any application. And, sure, you can set a quick-change post at odd angles, but then you've lost one of the advantages of even having a quick-chage post ... repeatability after changing tools. After such a change you have to reset the post, which wastes time. You create the same problem when switching to the lantern post. So, it becomes a question of whether it takes more time to realign the toolpost, or custom grind some really odd toolbit. I realize that there are some other more elaborate quick-change posts that allow intermediate settings, and might solve some of this problem, but that's not what I have.

Does anyone still use lantern toolposts
Dan and others, thanks.
Basically I have a set of size 0 toolpost and toolholders and I thought that I did not need them. I even listed them on ebay. Thanks to your feedback, I changed my mind, I will be canceling that auction and I will keep them. I can how see how a big bxa toolpost can get in the way. i |

I rarely use hand-ground HSS tools, but once in a while I have need for one in a special case. While I had an Atlas lathe around, I kept a lantern post, but only used it once every 5 years or so. It DID give you the ability to adjust tool height independently from tool angle, which is nice with the hand ground cutters. My feeling on this matter, without knowing too much, is that lantern toolposts are obsolete and quick change is the way to go, and there is never a reason to use these old style tools. I don't have a lantern post on my 15" Sheldon, and have not missed it. I can get what I want on the HSS bits, but you do have to grind the top rake into the tool, which does take a couple minutes. If you are going to use primarily carbide indexable tooling (your surplus connections should make finding some suitable inserts pretty easy) then the QC is the way to go. If you will be hand grinding HSS (Mo Max or similar Tungsten-Cobalt tooling is really fine and very available at flea markets, etc.) then you at least want a setup that allows you to control the tool angle so you don't have to grind the tops of all those cutters for top rake. When I got the Sheldon, I looked on eBay for a month or two and bought a lifetime supply of coated triangular carbide inserts for about a buck apiece, and then bought a 5-piece holder set for that style.

I really don't see why unless you had some holders and a post. If I did, I'd use them when appropriate. I have a genuine Aloris AXA on a spacer on my lathe. It came with it You want a BXA for yours.

Quick change is nice. Drop in a tool, do the job, drop in another. I don't have a dro but from what I have gathered, you can set up multiple coordinates so you can have each tool holder have it's own offsets. If I had a dro, I'd set the compound at 29.5 and square up the post. If I needed to use straight bit (C type) to cut a chamfer, I'd rotate the compound to what put the bit at 45 to the edge of my part. Then I'd put it back for all the other tools. As you can gather, I'd love a dro for my lathe. Wes -- "Additionally as a security officer, I carry a gun to protect government officials but my life isn't worth protecting at home in their eyes."

Use your lathe for a while. Eventually, you'll be glad you have the lantern toolpost. John Martin I agree with John. There are times where the lantern post is used. TMT Oh my gawd. I actually agree with TMT on something. Worse yet, Gunner may agree too. I once mounted a lantern on a large steel bar bolted to the carriage and had the tool six inches past the end of the lathe. The part was held in in a steady rest right at the end of the lathe (plus chuck on other end of course. So I turned a part longer than the lathe. Rare use, of course, but try that any other way.

I was just wondering if anyone who has a lathe capable of using a quick change toolpost like Aloris, would still have any reason to ever need a lantern toolpost. My Clausing came without a toolpost, and I put a turret toolpost which I had on it for a short while, while I ordered a Phase-II Series 200 (pretty much the same as an Aloris BXA), and have never used the turret toolpost since. I've seen used lantern toolposts, and never bought them (either on eBay or in surplus tool piles), even though I could have gotten them quite inexpensively. (Of course, if I did, I would also have to get several Armstrong style tool holders which would be (these days) almost as expensive as the Phase-II.) I *do* have the lantern style toolpost for my old Atlas/Craftsman 6x18" lathe -- because when I was using it, I could not find a properly sized quick-change toolpost. And the 7" Rockwell/Delta shaper has a lantern style toolpost too, but that kind does not have tilt built into it, and the tools which I have for the shaper are appropriate for the holder. It has the advantage of not adding as much weight to the "clapper box" as any quick-change toolpost would, and also I don't need to change tools frequently on the shaper. My feeling on this matter, without knowing too much, is that lantern toolposts are obsolete and quick change is the way to go, and there is never a reason to use these old style tools. Not on a lathe for which a good quick-change toolpost is available, at least. On the shaper, it is what works, and the quick-change is not needed. Would there be anyone who disagrees with this. I do not -- with the (non-lathe) caveats above.

Also -- some more elaborate tool holders for the simple Aloris style quick-change toolpost -- as shown above. Enjoy, DoN. I'll agree with most of what Don states above, with the following observations ... My toolpost is a Phase-II "BXA" sized dovetail post. It is completely satisfactory on the Rockwell 14" lathe I have at the university. I have a similar "AXA" size post on my Logan 10" at home. Yes, I have lantern toolposts and extensive sets of Armstrong-style tool holders and bits for both lathes at both locations. This *IS* important for my original argument. For most of my odd jobs I will already have some tool/holder combination that is close to what I need. Perhaps only some minor regrind is necessary, if that. Without the above collection of tooling, in most cases the work could be done by setting the quick-change toolpost to some odd angle and custom-grinding some weird toolbit (this can take considerable time, and may require a non-common toolbit (extra long, etc.). Switching to the lantern post and existing tooling is often much quicker. Basically, there's not much if anything that CAN'T be done with either style post. The advantages of the quick change a 1) rapid changing of tools without having to set angles and heights. 2) Repeatability of settings when changing tools. HOWEVER, when the work won't allow these things (easily), then the more versatile (if troublesome) lantern post may be the answer. Some of the specialized Aloris toolholders Don mentions would certainly assist in solving some problems. Sadly, the Aloris items are fairly expensive, and our department budget usually requires a cheap, of time consuming, solution. We're often "long on time and short on money". Phase-II doesn't offer nearly the variety in low-cost toolholders. I've made a few special holders for the Phase-II post (that hold tool bits at odd angles) that are useful. Some of the work I need to do involves machining (often INSIDE) complex shaped existing vacuum fittings and chambers and such. Cutting additional O-ring grooves or adding/altering ports are such applications. These structures are fabrications, customized for various research applications, and often have odd protrusions either inside or outside. Often these things are not well planned, but just 'grow' as the project develops. New ports are added, or fittings silver-soldered on. Old ports get plugged (not always neatly). THEN somebody wants further modifications. Just getting into the thing, or around the obstructions, is usualy the problem. Tooling to do this often requires a long reach and strange angles. Sometimes a boring bar, sometimes used as an EXTERNAL toolholder, is the answer. Sometimes a lantern post is the solution. In either case, a long reach is often needed, with corresponding lack of rigidity. Light cuts with sharp tools are a necessity. As is often the case, one spends 95% of the time on the setup, and 5% making the cut. Such problems rarely arise when making new items.

Been living in the UK since 1982 and the lantern types always seemed a PITA and have never needed one for anything I've done in the last 28 years. Apart from indexing 4 way toolposts that needed shimming I've almost always used Dickson type toolposts in the UK or IIRC the Swiss type fitted to some UK Hardinges which have a similar height adjustment. Both my current lathes have Dickson or Bison knock off toolposts. The main odd ball toolpost attachment I've run across was a local machinist that had a Bridgeport M head fitted to the cross-slide of his lathe. He had the head and had a requirement for a helical passage on a hydraulic heat exchanger. The heat exchanger comprised a heavy wall tube with one fluid flowing down the centre and another in the helical outer passage, it had a shaeth. He used a lathe about 20" - 24" IIRC and mounted the Bridgeport M head on the carriage and then did thread cutting as normal, with a very coarse pitch, but with a milling head doing the cutting. Impressive and worked a treat. |

Sometimes you want to use HSS cutters and not carbide.
Nothing like using Armstrong (who makes lanterns and holder to this day) tool holder to cut plastic and stuff that needs a sharp edge. Lanterns can be purchased from MSCdirect and other tool suppliers. IIRC, Armstrong sells direct themselves.

So far, several years and no damage to anything but an insert or two, which are expendables anyway. Too rich for me, Granted -- the $181.00 is not cheap -- and it cost less when I bought mine from MSC. Hmm ... their (MSC's) price is currently $200.00 -- significantly more than I paid for mine. And I haunted eBay for a while looking for one, but dropped out whenever a used one came within about 15% of the MSC *new* price (and they usually closed *above* the new price), so I decided that the new price was what I was going to have to pay. Consider that it takes the place of *two* normal holders. I have not regretted the purchase, as it is used more than any other tool (being good for both facing and turning with one holder). The extended holder (BXA-13) usually holds the insert threading tool. And that one is only $101.00. What size of lathe are you running? AXA are somewhat less expensive, and if smaller than an AXA will fit, you can't find the special tools anyway. Oh yes -- can you *find* the Armstrong type tool holders new these days? If so -- what do *they* cost?

[ ... ] I realize that there are some other more elaborate quick-change posts that allow intermediate settings, and might solve some of this problem, but that's not what I have. Also -- some more elaborate tool holders for the simple Aloris style quick-change toolpost -- as shown above. [ ... ] I'll agree with most of what Don states above, with the following observations ... My toolpost is a Phase-II "BXA" sized dovetail post. As is mine -- the wedge style, FWIW. The reason that I explicitly mention the Aloris toolpost is to call attention to the one with three dovetails, to increase the flexability. This I would like to have, but probably can't afford as a hobby machinist. But all of the exiting tool holders which I pointed out will work nicely on my Phase-II Series 200 (their designation for BXA). It is completely satisfactory on the Rockwell 14" lathe I have at the university. I have a similar "AXA" size post on my Logan 10" at home. O.K. Yes, I have lantern toolposts and extensive sets of Armstrong-style tool holders and bits for both lathes at both locations. This *IS* important for my original argument. For most of my odd jobs I will already have some tool/holder combination that is close to what I need. Perhaps only some minor regrind is necessary, if that. Without the above collection of tooling, in most cases the work could be done by setting the quick-change toolpost to some odd angle and custom-grinding some weird toolbit (this can take considerable time, and may require a non-common toolbit (extra long, etc.). Switching to the lantern post and existing tooling is often much quicker. O.K. [ ... ] Some of the specialized Aloris toolholders Don mentions would certainly assist in solving some problems. Sadly, the Aloris items are fairly expensive, and our department budget usually requires a cheap, of time consuming, solution. We're often "long on time and short on money". Phase-II doesn't offer nearly the variety in low-cost toolholders. I've made a few special holders for the Phase-II post (that hold tool bits at odd angles) that are useful. O.K. I've seen holders for other systems which hold the tools at strange angles. Some of the work I need to do involves machining (often INSIDE) complex shaped existing vacuum fittings and chambers and such. So -- not only are the workpieces strange in shape, but also usually stainless steel to survive the bakeout prior to high vacuum work. Cutting additional O-ring grooves or adding/altering ports are such applications. These structures are fabrications, customized for various research applications, and often have odd protrusions either inside or outside. Often these things are not well planned, but just 'grow' as the project develops. New ports are added, or fittings silver-soldered on. Old ports get plugged (not always neatly). THEN somebody wants further modifications. Just getting into the thing, or around the obstructions, is usualy the problem. O.K. This is something which calls for using whatever will work, and not a problem which I normally encounter. Tooling to do this often requires a long reach and strange angles. Sometimes a boring bar, sometimes used as an EXTERNAL toolholder, is the answer. O.K. The Aloris style boring bar holders can be a good start on this, with the lantern style toolholder at the end of the bar. Sometimes a lantern post is the solution. In either case, a long reach is often needed, with corresponding lack of rigidity. Light cuts with sharp tools are a necessity. As is often the case, one spends 95% of the time on the setup, and 5% making the cut. Understood. Such problems rarely arise when making new items. Which is what I normally do -- so your case is extreme, but may apply for others here too. Since I don't have the collection of Armstrong type holders, going to the toolpost would represent a significant expense for me, just to get the holders. And that is money which I would rather put into getting one of the adjustable angle Aloris insert holders.

DoN, I am very curious.
On the one hand, you can have this turning and facing holder, or its knockoff ($70 on ebay). On the other hand, you can have a regulr toolholder and insert indexable lathe bits in it. Would you say, as it seems, that the former is somehow better? Why? Just because it is more rigid? i |

tool holder to cut plastic and stuff that needs a sharp edge. IIRC, Armstrong sells direct themselves. http://www.armstrongtools.com/ECommerce/Category.aspx and scroll down the left navigation to "workholding" (yes, I know it's toolholding, but that seems to be where they've lumped it in). I seem to recall paging through an Allen Tool catalog that listed a bunch of this style toolholder as well, but in searching for them, I found they were part of the Danaher group along with Armstrong, so I guess that comes as no surprise. --Glenn Lyford |

I've seen some which sort of look like it, but present the inserts corner first instead of one edge first in the direction of cutting.

On the other hand, you can have a regulr toolholder and insert indexable lathe bits in it. Two regular toolholders, and two insert holders and inserts. *Good* insert holders (those with negative rake and support ships) are expensive too. I've worked that way, and I far prefer the BXA-16N double insert holder. Would you say, as it seems, that the former is somehow better? Why? Just because it is more rigid? It is noticeably more rigid than an insert holder in a standard holder. It takes the place of two holders with tools. I only have to have that one holder and a parting holder for most turning that I do. Another holder for threading inserts. (And of course other things like the dovetailed scissors style knurling tool, and other things -- but mostly it is just the BXA-16N and the parting tool swapping places in the tray on top of the headstock.

AFAIK this is the complete set of tool holders for the Swiss system: http://www.top-maschinen.de/spannwer...ifix/index.htm O.K. But this does not need holders with strange angles, because the holder itself can be indexed in 9 degree increments. What I was talking about was a holder for another system similar to the Dickensen (I'm sure that I don't have that spelled right) system, but not quite it. The holder, instead of holding the tool shank parallel to a line tangent to the ways on the post holds the shank at about a 30 degree angle to the tangent line. I forget the brand, but I wound up with a holder for that system when I thought that I was bidding on a holder for the Emco-Maier smaller Dickensen. Hmm ... it was probably "Enco" that I confused. Anyway -- I exchanged it for one of the right type that someone else had which did not fit *his* toolpost. :-) I've never seen dedicated carbide insert holders, nor any of the other variations the Aloris system provides, like drill chucks. The drill chucks, and the Morse taper holders can be useful when you are doing a lot of on-axis peck drilling when you need to do a lot of pulling the bit back out to clear chips. Use the power feed, disengage the feed, crank back with the carriage handwheel, tap to drop chips, crank back in until the tip contacts, and re-engage the power feed. A *lot* quicker than cranking on the handwheel for the tailstock, but if you have a lever-feed tailstock, or a bed turret, it is not as useful. Come to think of it -- I also have a three-jaw cut knurling tool on a Morse Taper shank which goes nicely in the Morse taper tool holder.

They are almost as rigid as a one-piece tool block, and they are quicker and of course easy to index. But there are times where you have to work in a tight area for which they are simply too large. That's where the lantern toolpost becomes necessary. Use your lathe for a while. Eventually, you'll be glad you have the lantern toolpost. John Martin And I agree. In fact...while a KDK lives MOST of the time on the Hardinge HLV-H..I keep both a lantern and a small Hardinge turret tool holder in the side cabinet. There are just enough times I need to work either up next to the collet..or actually behind it, to use both of them.
