Milling on the lathe Vertical tslot table or vertical milling vise?
1. Before anyone even starts a REAL milling machine is in the works but
the 2 demons of all workshops are working against it Money and Especially space so until the new workshop is built i have a lathe and room for it but NOT a mill or even a Mill/Drill asian thingy I know this is aimed mainly at the hobby people because most sane people would used a vertical mill for vertical milling and a lathe for turning. As i said though the time and Space demons are on me so to me it makes more sense to be able to do some limited milling in a lathe than to do nothing waiting for the mill Has anyone used the Palmgren vertical vise miling attachment or a myford vertical table? which would be the most versatile to serve until i could get a proper milling machine? Any help is appreciated |

I have done lathe work on the vertical mill Just put the work in the collet, and the lathe bit in the vice. -- Accidental creation should not be taught as a fact. Intelligent creation should not be banned from teachings as unconstitutional. |

Milling on the lathe Vertical tslot table or vertical milling vise?
My first metalworking investment was a PRAZI lathe with the milling
attachment. Used it for several years before advanced to an EMCO lathe with milling head, then a mill/drill. The lathe/mill adapter is very limited in how big a part it can mill. Also, not very rigid. But it does get you going. Since both of the attachments you ask about attach to the cross slide on your lathe, you can determine the maximum length of a pass you can make. How do you intend to hold the end-mill? Do you have a collet setup for the lathe? If you are going to use small end-mills, the maximum speed of the lathe may be a little slow. Good luck! Paul |

Milling on the lathe Vertical tslot table or vertical millingvise?
I've only done a couple of milling projects in my Atlas 10F lathe, but
it sure can be done. My lathe has the Atlas milling vise, which, I think, is similar to the palmgren. Don't plan on any heavy cuts. IMHO you HAVE to have a collet setup for the milling cutters, though. HSM has had several articles over the years where the author has done milling in the lathe. I was always jealous of Myford owners with that t-slot compound, too. Pete Stanaitis ------------------------- Brent Philion wrote: 1.

Milling on the lathe Vertical tslot table or vertical millingvise?
I dont have a collet setup yet its in the "to get" list along with the 4 jaw
the lathe needs a tooling update since most of it is 50 years old and i will gradually deal with it and i want to swap out the old lanterns style toolpost for a quick change and so on I think caution and milling SLOWLY and carefully will counteract some of the lack of rigidity but by the same token i know its a tradeoff i'm making until i can afford a real milling machine but the question is am i better off with a vertical slide table and a T-slot clamping kit a la myford or a vertical slide milling vise http://www.palmgren.com/palmgren/p-m...ttachment.html I know there are guys in this forum just WINCING seeing me look at these piddly things compared to a real mill wrote: My first metalworking investment was a PRAZI lathe with the milling attachment.

Atlas actually had one that they made too?
I actually have a 10F that i'm using for this as far as i can see i CAN buy a Myford slide and make it work on the 10F compound with minimal adapting but you think it would be superior to a vise arrangement? spaco wrote: I've only done a couple of milling projects in my Atlas 10F lathe, but it sure can be done.

snip
Hmm ... consider the possibility of using a Morse Taper end mill holder which matches the spindle nose, and making a drawbar to hold it firmly in place. (For that matter, A Morse Taper collet could be used as well. snip A morse taper collet is certainly usable but because you most likely will be changing mill cutters several times in any project, it will be much easier to use a end mill holder as this will require only the use of a allen [hex] key from the front of the spindle. A morse taper collet must be have the draw bar slackened, tapped forward in the spindle, the end mill changed, and retightened. This gets old very quickly and there can be a tendency of the endmill to shift in/out of the collet. For typical home shop machining you will only need one or possibly two holders 3/8 and 1/2 inch.

spaco wrote: Thank you for this information. It will go on my gift list. ("It" being the MLA cross-slide casting.) Pete Stanaitis So now that I take another look at this, why could you not just use a chunk of steel and machine it to the dimensions on the drawing, to fit your crossslide? Is it really that advantageous to use an iron casting? Yes. The reasons which come to mind a 1) Since the casting is close to final size and shape, there is less metal to machine away, and thus less waste. You'll need to borrow time on somebody's milling machine if you don't already have one -- and given the reason for the T-slotted cross-slide, it would seem apparent that you don't have one. I don't think that you have enough travel on the existing cross-slide to get away with milling it in the lathe. 2) Cast iron tends to absorb vibration a lot better than steel does, so you have less contribution to chatter. 3) Cast iron on cast iron dovetails will wear better that steel on steel will. 4) I think that it will be easier to mill the T-slots in cast iron than in steel. (That said, I've milled a circular T-slot in a 6" diameter chunk of 12L14 -- probably the nicest machining steel readily available.)

It looks like there is one there meant for the atlas but they make you
buy the atlas table then the base and the milling slide instead of the southbend where the base is optional Though i'd love to have a second set of eyes confirm that Mike Henry wrote: Maybe things have changed, but as of a couple of years ago MLA didn't have any of the Atlas T--slotted cross-slides for sale.

Milling on the lathe Vertical tslot table or vertical millingvise?
It looks like they have all the appropriate parts now but i dont trust
my eyes to confirm If the T-Slot cross slide and purpose milling slide are ready then it seems liek ti would be a much better thrid option option 1 was to shoehorn a myford mlling attachment onto the top of my compound (Not rigid at all really) Option 2 was to attach a palmgren horizontal vice to the toolpost on the same compound this creates option 3 and seems to be the most solid and rigid solution to my problem as it seems to be purpose built for the Atlas rather than a shoehorning as such i'm calling MLA in the morning as well Brent Mike Henry wrote: I didn't explain that very well.

Uncle George I don't understand the page with the boring head. http://www.mcduffee-associates.us/ma...oring_head.htm The pictures are probably supposed to be self-explanatory, but it's not working for me.

http://www.mcduffee-associates.us/ma...oring_head.htm Since you don't have calibrations like a real boring head, you need some way to measure how far out you have set the tool bit. The extra block allows you to do that. Gingery uses a similar method in his books as well. --Glenn Lyford |

Any help is appreciated Since nobody has replied about the vertical table vs. vise, I'll comment. I've got a Palmgren milling slide with a slotted table instead of a vise, I've always regretted that. By the time you get a vise on the thing, you've got a whale of a lot of leverage on the compound. I replaced the lantern TP mounting forks on the milling attachment with a disk that fits the compound hole on the 9" S.B., it helped, but not a whole lot. Still a lot of leverage there, things moved while cutting. I made my own milling cutter holder for the headstock, cut off a large MT3-shanked drill, drilled and tapped the small end for a drawbar and bored a hole in the other for the cutter shank, secured with a setscrew. Still couldn't do keyways very well. Solved it by going with a Aamco shaper. I now have a small vertical mill for that stuff. The slotted vertical table was good in theory, being more flexible than a vise, I just couldn't get a solid setup that way. Stan |

UPDATE AND THANKS Milling on the lathe Vertical tslot table or vertical milling vise?
Just wanted to Toss an update
Two weeks ago i bought the MT3 to Weldon endmill holder and a few days later built its drawbar On thursday the Palmgen 400B milling adaptor came in and this weekend i'm going to make a holddown for it (My current rocker toolpost is a bit too small so i'm going to turn one this weekend hopefully to fit what the milling attachment is expecting) thanks for the advice to all who posted. this should keep me doing some limited milling until such time as i can afford a real mill or mill/drill |
