Vertical Mill slide
While I agree with a lot that has been said regarding a vertical slide ,but to say that it is crap, is to my way of thinking not right, as it has been said that much good work has been done with a vertical mill attachment ,long before mills became as cheap as they are today and if you can still afford to buy one,very nice, I would like to have a good vertical mill that would replace my milling attachment ,but I have managed to make a few things with it over the years and I don't think,I would be with out it,when all said and done its really only a hobby tool,would be hard to be in the trade and use only that mill,.
I now have a H&F vertical slide or mill,and it is not in my humble opinion a fragile thing in any way,and I have owned it for many year's, a couple of pics to show ,and I drill and fix many bits and pieces to it to get a job done, Will swivel every way ,a couple of photos of the type of models you can make with this type of mill,and they are all out of the scrap box,no castings,pluss I have made many tools with this Vertical Mill Slide,just my opinion .

Sorry Redgum missed your post. I'm heading off to Renmark tomorrow, if your around next week I can detour via the Barossa.

In regards to these types of slides,I have a few questions for people who either have them or people that may want them,if the purchase of a suitable sized milling machine was out of the question.
How would you prefer the slide to be attached to your lathe.( compound or cross slide .)
What type of work envelope would you consider to be standard for the vice,but also retaining a reasonable amount of rigidity.( jaw opening for vice and depth .)
Would you require it to be able to rotate.
Would you require it to be able to move left to right,and if so by how much.
Would the material it was made from be a concern.
And any other things that may be needed.

> How would you prefer the slide to be attached to your lathe.( compound or cross slide .)
If your lathe weighs less than 500kg, you do NOT want to mount a vertical slide to its compound. It would not be rigid enough for anything larger than two sugar cubes.
> What type of work envelope would you consider to be standard for the vice,but also retaining a reasonable amount of rigidity.( jaw opening for vice and depth .)
your work envelope is not limited by the vise. It is mostly limited by tho other things:
- your overall cross slide stroke
- how much your vertical slide stroke can extend downwards (before hitting the lathe bedways)
Assume your cross slide stroke is 140mm (that is your X axis). In order to mill a flat on a workpiece, your milling cutter needs to sweep the whole length of the workpiece. Assume you are using a 12mm endmill. Then your x envelope is 140mm -12mm -12mm = 116mm for a nice finish. About the length of a cigarette pack. Or 12mm more, if you are happy with the finish left behind by a cutter that starts and stops halfway into the workpiece.
Assume you are using a small flycutter, say set to a 50mm diameter. For a nice finish, you expect the flycutter to fully clear the workpiece. Then your envelope is 140mm -50 -50 = 40mm, about the length of a match box.
Of course, a larger lathe has a larger cross slide stroke, and a smaller lathe a smaller stroke. This is just an example.
Regarding the Y-axis (the vertical slide axis), this is almost invariably less than the cross slide stroke, because of the lathe bed being in the way.
> Would you require it to be able to rotate.
Not really, or only rarely. It depends what you do. If you need to do compound cuts, then it would be an advantage. However, keep in mind that vertical slides that can swivel are almost always less rigid than vertical slides that do not swivel. This is certainly true of all lathes with T-slotted cross slides. Maybe not so much with lathes that mount the vertical slide in the compound hole, like Hercus/Southbend/Myford, as these are swiveling by virtue of the design.
> Would you require it to be able to move left to right,and if so by how much.
Left right like in Z-axis? Well, that is the movement of the lathe saddle, and it is usually the whole lathe bed length. Not sure if that is what you meant....
> Would the material it was made from be a concern.
Yes of course. Cast iron is ideal. Aluminium would only be acceptable for a watchmaker size lathe (a lathe of less than 10 kg with motor and chuck included)
> And any other things that may be needed
YES: you absolutely need a handwheel with graduated dial to fit onto the right end of the leadscrew. This is a MUST HAVE and it should be part of any vertical slide package. Whitout this, you cannot accurately feed the depth of cut. It would be like using a simple drill press for milling, using the quill downfeed to set the depth of cut. And you need something like a collet chuck to clamp the milling tool. Using a drill chuck is a NONO. Using the 3-jaw chuck may work in a pinch, but on the long run you want a collet chuck. Chris

Slides
I personally wouldn’t mount a slide on the compound, even though the compound is quite substantial on my lathe (as compared to my previous lathe), I don’t think it would be rigid enough, the top slide would be my ideal. In terms of movement the lathe top slide and the vertical slide should mimic the longitudinal and cross movement of a mill table, the lathes apron movement should mimic the mill’s vertical travel and a swivelling slide should mimic a tilting head mill, sort of.
Neither the Hafco nor the Sieg look to have a wide enough foot for my lathe, my lathe has quite a substantial and wide top slide, probably because the bed has mounting points for an optional mill. Not sure about vertical movement but the Hafco slide I had, had ample for my requirements. Vice size probably in the vicinity of 2-3 inches, not that important as long as the slide has a table (Hafco type) rather than a built in vice (Seig type. Not that fussy on material as long as it’s rigid..

Vertical Slide
Sorry about the pics being removed, not my doing, I tried to post the pics from my WWF Album could not get it to work ,not educated enough for a computer,it works some times and then the memory fades, but the mill was bought from H&F many years ago not to certain how long in th late eighties or early ninety's, cost $240-00 then ,it is heavy to ,I just remove the compound slide and attach it to the cross slide ,I can post the pics again unless they have been removed by the big boss,I can not understand what has happened.
I have just had a brain flash after J posted them pics I moved a few pics into the correct part of Photo Buckets Album.would that have removed the pics
from WWF .sorry about this.
