It's very smart to make prototypes. I was an engineering manager for a lot of years and one of my slogans was, "Prototype EARLY and OFTEN." Another close cousin was "One test is worth a thousand opinions." Many engineers do a lot of living in their head, which is fine, because that's where the ideas come from. But it helps to get tangible quickly. It is also the best way to show a design to somebody else for comment.

Thank you! Yeah it’s a remarkably capable setup once everything gets tightened down. Just need to be patient with it and go slow and you can get some really good results!

A key issue with any type of milling attachment such as this is that there’s a lot of overhang to the left of the cross slide, and it puts an undo load on the gib. You gotta figure out a way to brace the load as it hangs out during machining, especially milling. What I did with mine, which is on a jet lathe is I built it as far back as I could so that the main load is actually over the cross slide. I also built in some extra strong locks for the cross slide gib, whenever I’m not moving that axis, which I call the X axis.

Also if you do decide to go with collets don't buy Morse taper collets they are relatively expensive, hard to find and limited in their capacity. I would get an ER collet chuck. They allow for the work to pass through the spindle and their clamping force is much higher.

I bought a lathe made in a Soviet factory that came with Morse 2 collets as an addition to decent self-centering three jaw chuck. The collets are unusable. I am not sure whether it is because of it is inferior construction, or because they were made in Russia (or a combination of both ;-) )

Many moons ago when I was a poor student I built such a vertical slide for my 6" Atlas lathe. It worked very well and eventually used it to mill the flutes in the coupling rods of the steam locomotive I was building. This device must be used carefully because it imposes a lifting load on the cross slide left hand dove tail, for which this dove tail is not meant to be used. Light cuts is the guiding principle here.

Been thinking about this , made prototype, found the forces are opposite to a mill. The forces are not handled well by the crosslide, wheras the spindle takes all forces unmoved. Going to get a small mill, knowing problems arise there too. There are lots of info about them.

Neat - I bought what looks like the same slide. Your design pretty much mirrors mine - I was going to suggest rotating the screws that pick up on the top slide mounts to a slight angle so that they cleared the base of the vertical slide, and in the next minute you'd done it (as you know, it means that the adaptor plate can be taken off without having to unbolt the vertical slide first). I put a dowel into the cross slide where you tapped a hole, and I tapped holes either side of it (where the bolts can go into the thickest part of the cross slide. The combination of dowel and the 'nub' where the top slide mounts means that the slideway can be removed and replaced with out needing to indicate it in to parallel. I did manage to knock the dowels out of the base of mine, making it easier to mount - I've had to make a few more tapped holes for different mounting options to suit specific jobs (such as having the slide parallel to the bed so that long things can be held sideways in the vice - my first project was also some clamps to hold a vice to the slide. A graduated collar for the leadscrew is handy for dialling in cuts, and as others have said, it's handy to be able to use the tailstock to support the slide. I use morse taper MT3 'finger' collets directly in the spindle taper to hold milling cutters - they're cheap, and you only need a few sizes to suit the mill shanks. (You need to make a draw-bar, but that's just a long bolt and a collar.) I ultimately ended up ditching the supplied mounting bracket and modifying the slideway so that it bolts onto a small, cast iron, right angle bracket bolted to the adaptor plate - I never used the rotation features (there's not enough slideway travel) and this makes for a more compact setup with less overhang. For those people talking about flycutters - the X slide travel is extremely limited - you would want to clear the work at each end of the travel, so the size of workpiece you can flycut is tiny - something like a 10mm / 3/8" dia end mill is just as quick. Good luck!

You don't really need a collet chuck. Although they are extremely useful. You could use a Morse taper 3(I'm guessing that is what the lathe uses) endmill holder. But with those you would have to get endmills that have Weldon flats on them. Also not sure if you can get one that is metric. The one I have is SAE and takes 3/8" shank mills.

Of course there are metric weldon holder, they are more common than bald eagle per school shooting ones, because almost the entire world uses metric tools. And you can just grind a flat on a endmill. I wouldnt use weldon on such a small lathe, because of the runout error of the weldon.

Nice project. I have a similar rotational issue to solve for my cheap import milling attachment. I'll be using some of your ideas to get to the solution that I need. One of the less-important details that I noticed is that we both made the same fan cover for the control board of our respective printers :)

You should make the mounting plate or The 3D printed version file. I'm new to this and want something that's just plug and play. Considering the same lathe as you. Nice video!

I fully expected the mill slide to cant back away from the endmill. I do milling on my lathe and this is always an issue due to any movement in the cross slide dovetails. You handled it as well as can be expected. One trick you can do when drilling into work is to use the tailstock as a centre line brace for the mill slide. It will stop any canting. Overall the little millslides work quite well considering their short comings and limited x/y range. Enjoy. Cheers Rob

@@Someone_Should_Make_That I forgot to mention that you use the tailstock quill to push the carriage and work into the drill bit. Another thing that will give a better finish with less chatter is to "ramp cut" when milling. Feed the job into the cutter (away from the operator) front to back and this will cause the mill bit to push down on the job with it's cutting action. If you go back to front (towards operator) it will try to lift the table/job and cause chatter. I hope this helps. Cheers Rob

Good job !!!

Steve Jordan has several videos on milling on a mini lathe and a mayford lathe that are very good. I have made several of his set ups to mill on the lathe that have worked very good for me.

Hey, great video and review! honestly, it looks like a decent cheap milling table, just some rigidity and tolerance slop easy-ish fix. Something of note: Does your drill press have the pulley speed change? if it does, using that will help a lot with metal. Also, grab a cheap bench grinder and sharpen your own drills. Just learn on the burnt out ones 😮. My opinion on chucks is to get a four jaw chuck. It will open the way for larger work holding and off center boring ... incase of a repair, so to speak. Again, this is a great video, and I hope you're enjoying the hobby.

Thanks for the video. I will have to look into getting one of these. If you continue to just use this with vices and such, the dip in the top (Z axis) face that you showed should not be a problem. But still I do agree with Sean Signer, lap that surface with the glass and sandpaper method. I assume that you are aware of Quinn's Blondihacks channel. The reason that I mention her is that in looking at your carriage lock, it could use a handle of it's own, even more so when it is hard to get to such as when you have the milling attachment on the carriage. She had one for a time on her lathe that was ugly, but worked.

A lot of people are commenting about getting some collets but I feel the scope of this project is to get the most for the least the same way a giant shop with unlimited resources often do. Running an endmill in a conventional chuck works but you'll have to compensate a lot due to the end mill runout. The closer the chuck jaws are parallel to one another is a key point, if not you'll get a not so flat and square part. There are plenty of videos on grinding 3 jaws chuck to run true, a cheap dremel grinder could be adapted. I'd say enjoy what you have to work with but save up some money for a real machine, like a Bridgeport and a complimentary quality lathe.

Hey. Very nice and interesting to do the same. Some question.. what's your lathe Swing distance is it a 7x14.. if so. Do you have experience a need for more length yet ..? I gonna buy one but maybe bot bigger if i could. Thanks man.

Hey! Glad you enjoyed the video! My lathe is a 7x12 and I have not run into the need for additional length yet. My main deciding factor when I was buying mine boiled down to the fact the 7x12 was much cheaper than the 7x14 so I went with it, and I have no regrets with that decision at all. Your mileage may vary depending on the kind of parts you make of course, the best advice I can give is get the biggest one that makes sense for your budget and space available (keeping in mind that $200 dollars in savings on the lathe can let you pick up a set of cutters and some tooling if you're stretching the workshop budget like me!). Hope this helps and good luck with your projects!

This was cool to see! I'd been wondering about the value proposition of some of these milling attachments. That play in the cross-slide looks really frustrating! Had you already noticed it before this project or nah?

@Someone_Should_Make_That

Glad you enjoyed! I haven't found the cross slide play to be an issue when operating the lathe normally. The large distance between the dovetail and the actual cutting location exaggerates the effects quite significantly (it's a very slight movement, if the oil wasn't being pushed out slightly I wouldn't be able to see it). I could probably reduce it by fine tuning the gibs screws, but locking and unlocking that axis for each vertical slide cut isn't too bad of a trade off.

What this tells me is that: If you want a lathe that can double up as a horizontal mill, buy a lathe with a bulky cross slide

@Someone_Should_Make_That

Good tip! Yes it handled everything I threw at it quite well. If your lathe has a larger cross slide it will likely perform even better.

That design of vertical slide is a copy of the Myford one. In some ways the Myford one is not as good, others it was better. I think the original one is less beefy, but it looks like the original has better quality screws than the copy. I don't think those quality differences will affect the quality of the output that much. My main observation is that the Myford version was designed specifically for use with a Myford 7 lathe. I think your mini lathe is a bit smaller. It has smaller gibs. That will make a difference to the quality of the work you can produce on the vertical slide. If you could get a slightly bigger lathe it would help improve the output quality of the vertical slide by quite a lot. I have a milling machine now but I used a vertical slide for years on my Myford. Actually I still use the vertical slide instead of the mill from time to time. The one advantage that the vertical slide has over a small vertical milling machine is the long effective z travel (the length of the bed). When you want to mill features into the end of something quite long the vertical slide pays dividends.

I used to use my vertical CNC milling machine as a lathe when I didn't have a dedicated machine for turning by my side. But the major problem with such shortcuts is that our life should be way longer than it can be in order to afford that kind of approach. But if choosing between either having a manual lathe with a vertical attachment or having a vertical manual mill I'd go with lathe + attachment for sure because a lathe is more versatile machine than a mill.

I learnt a valuable lesson from simply being on the same ship. That was the importance of accuracy and tolerances. It was a very valuable lesson and the mistake made was in recutting a thread that didn't need recutting and the entire problem of a tiny drip would have been easily solved with the proper use of thread tape and or some adhesive that was fuel safe. Instead the officer chose to redrill the hole and tap a new thread. It cracked the cast iron drain assembly on the number 1 aviation fuel tank. This meant the ship could not refuel helicopters whilst underway. Refit...sorry fleet our vessel isnt sea worthy...not a phone call I would wanna make aye .

I was surprised how chunky that gib in the vertical axis dovetail was. Plus, it looks like brass. For 140CAD I would have expected flimsier construction. Perhaps you could also buy a version without the compound angle feature, just to make it more rigid in the vast majority of scenarios where you only need to mill right angles. Look at the prices of collet chucks, they are not that expensive. Plus, they can be used for lathe work as well.

My recommendation is to hold the milling cutter is a square ER collet block, held in the 4 jaws chuck. Why, because these are items that you will want and use all the time. If one really want an ER collet chuck then make sure that you get the biggest that is available for your lathe, because you may need to hold work of some size in it, not just cutters.
