Mod the design by installing an additional tapered roller bearings opposite each pillow block, allowing for axial loads and increased radial load bearing surface area(use JBWeld or cement/epoxy for vibration damping). https://www.youtube.com/watch?v=gjNuzIIXJeY lathe headstock design https://www.youtube.com/watch?v=Y0pBPqj5lR8 another spindle design https://www.youtube.com/watch?v=b8G55W060dc part 10, replaced self alignment pillow block bearings with vehicle angular roller bearings for axial load. Probably the easiest diy way to make a lathe, hence migrating dexter144 to the top.

https://www.youtube.com/watch?v=_Jf0F6CiQcQ Hey, you're doing a great job there! The only thing I don't personally like is the center-height to beds' width ratio. The more the height you set your spindle at without either widening the beds or reinforcing the overall structure, the lighter the duty the machine will be able to support during normal operation before it starts to flex/vibrate.https://www.youtube.com/watch?v=LY6wmHL48H0. quill lock, Shimming of any plane perpendicular to another in the x,y and z axis is done with a granite cube and describes method of using Moglice or JB Weld to create a headstock. Any number of orthogonal and parallel planes or axis are created with a granite cube. Lathe uses a 1:1 cement, epoxy mixture as cheaper alternative to Moglice. It forms a paste that takes 24 hours to cure allowing for the alignment of the headstock with lathe bed with lathe head tramming method. channel floweringelbow 25% slow cure epoxy, 69% iron powder, 5% aluminium oxide, 1% magic dust? for mating two pieces of metal.

Zaxis column are angle iron pieces with flatbar diagonally in center making a side to side square tube like structure drilled and tapped for linear rail each(6min33), it is more rigid than just a square tube for the same dimension. The back of the Zaxis column is reinforced with Uchannel that has a section removed at an angle. (7min21). Large rigid table for hoisting Yaxis from the ground for further wedling and drilling, is built out of Uchannels(9min). The Yaxis base is so heavy that the table is held rigid in the center with a hydraulic jack. In video nr.2 of the playlist the Yaxis is lifted on the rigid table built in vid nr.1. It's not clear how the ways were milled for the linear rails(see Moglice, Shimming, hand scraping). The video is in Polish, Google's algorithms don't list if for an English audience and the low view count betrays that is probably one of the best lathe and mill videos, showing clearly how to build a large heavy duty mill out of scrap Uchannels and Tchannels.

In comparison with machine beds made from iron-based materials, Granitan® machine beds have a more favorable thermal and better cushioning behavior. Temporary temperature fluctuations are largely compensated by the favorable thermal behavior of Granitan®. The excellent cushioning behavior of the machine bed ensures outstanding surface quality of the ground workpieces. Far fewer energy and raw material resources are consumed in the manufacture of Granitan®, in comparison with the manufacturing process for steel. https://www.studer.com/en/

https://www.youtube.com/watch?v=bKREUByofzE remade the entire frame out of 40x40x2 steel box and TIG welded it using a technique called winging it. As a known side effect of this technique the frame is not square, straight, coplanar, or any of the required properties for the frame of a machine like this. I solved it by shimming almost everything on it with washers of different thicknesses and a lot of brute force. In the build of the aluminium one almost everything went perfect first try, in this build I had to wrestle with it a lot, way more than I'm capable to show in a single video. The machine is obviously more rigid than the aluminium one and after a lot of fiddling with it, it is surprisingly straight where it counts and seems to even be properly trammed. As a bonus at the end of the video I decided to obliterate some aluminium and steel with the wrong dull bit and completely wrong feeds and speeds.

Here is a project I have been working on for a couple of months. The construction and mechanization of a lathe machine, I have only finished the first part of this lathe machine, i still have to place the engine, the headstock, the chuck, the tailstock and a few other things ... Each of the pieces was manufactured and hand ground. Unfortunately I could not film each and every one of the pieces made, they are many hours of work. I have had a few difficulties in this job. I have done everything self-taught, reading some books (there is not much about building lathes) and watching some tutorials on the web ... I hope I can move forward in this quarantine !! And finish as soon as possible so I can start working on iron sculptures (which I am doing this for), that is my medium and long term commissioning

accidental science
https://www.youtube.com/watch?v=w5DIehtaRM4 headstock alignment. That kind of alignment accuracy is obviously very good. Except as a general rule both the lathe head stock and tail stock are purposely misaligned by roughly .001" in 10"-12" over the length of the bed both up and towards the operator. That slight misalignment is done in an effort to build in a compensation factor for both work piece weight and cutting tool pressures. It's obviously not a perfect system since both the work piece weight and cutting tool deflection can have large changes depending on what's being done or even the cutting tool material used. So it's a best case average that helps the lathe deflect towards being more accurate instead of less in most cases. And that was very clever thinking to use a weight counter balance to remove the test bars sag due to gravity.

six part lathe build, welding and destressing. The dovetail milling for bed ways is preferred over this method. https://www.youtube.com/watch?v=0BuqkRqqxyk This time I show how I've made the cross slide of my DIY metal mini lathe. No welding: even this part has been made without welding but joining the elements together with epoxy and pins, avoiding the risk of deformations. In this part only the cross slideway is shown while in the next episode I'll show the cross slide's sled. https://www.youtube.com/watch?v=5rLqkpy2UQA part8b How I've made the sled of the cross slide for my home made metal lathe. Using the same technique applied for other parts of this lathe, I didn't welded the elements, rather I put them together through glue, pins and screws to avoid deformations and achieve higher quality and precision. This time I used cyanoacrylic glue (similar to superglue) in place of epoxy, because pins and screws are enough to keep the parts in place and the elements are attached together quicker.

Stepperhead
http://www.lathes.co.uk/stepperhead/ Designed and built by Alan Jackson, the Stepperhead is an attempt to combine, in one unit, the range of facilities found in a medium sized lathe and a small vertical/horizontal milling machine. In the 1950s David Urwick had designed and built the ingenious and versatile Metalmaster http://www.lathes.co.uk/metalmaster/, a device that combined a lathe and milling machine without unduly compromising the attributes of either. http://www.lirtex.com/robotics/diy-cnc-machine/ http://twilightrobotics.com/cnc/cncnot1 how not to make a cnc

I hope this will be the last part of the construction of my homemade lathe for metalworking. So, at first I thought to make a transverse feed on the basis of rail guides for CNC machines, but at the moment when I decided to buy them, the war in Ukraine began, and it was impossible to buy and deliver something. The same is true with buying from China. I started to do everything on my own - angles, plates, welding ... But I think in time it will be possible to redo. Then I took the cutter holder, made one cutter 25 mm high, the design turned out to be massive and strong, as for me. The last stage is painting and assembling the structure together. Well and the most interesting, it is the first shaving and test of my self-made lathe on metal. Watch the video, rate, comment on what you like or not. The lathe is a very useful thing for any craftsman, in the garage or workshop will be an indispensable helper. What you need to make a metal lathe in your home workshop - a piece of channel, a pair of angles, profile pipes, electric motor, lathe chuck, wide thrust bearing, drive pulleys. And from the tool, it is an angle grinder, drill or drilling machine, files and welding machine, and most importantly a great desire to do something with your own hands. Not 1K62, 16k20, TV-4, Izh250. The self-made lathe on metal is made of scrap metal. https://www.youtube.com/watch?v=dHRjYQW9j5w wasteland workshop mill build using commercial xy axis https://www.youtube.com/watch?v=SdhnnC3YtG4 linear guides(no music) https://www.youtube.com/watch?v=BZ3vIzjcZ2U workshop from scratch The machine is very helpful in making the widening of steel wheels, for the drive I used an electric motor with a gear, the engine speed was additionally reduced so that it was possible to weld not only with the mig method but also with the tig method. With such a widening of the wheels, work must be done very carefully, without haste, weld with high current to perform remelting. The wheel that I widened is much harder to widen than the regular wheel, but thanks to the rollers, I managed to make this wheel perfectly, the rollers help to center and align the wheel axis https://www.youtube.com/watch?v=6FBkKRp4HM4 workshop from scratch The frame made of 32mm tube diameter, the brakes and suspension parts are from Yamaha YFM700 ATV Quad, universal shock absorber for ATV Quad. I also changed the drive to make the quad slower and stronger. The front rack is one tooth smaller, the front rack is 4 teeth larger. After completing the project and the first test drive, I was pleasantly surprised by the ride, the quad does not reach high speeds anymore, but has a very good acceleration. Ride this ATV for great fun. https://www.youtube.com/watch?v=Xfm0t0SrAWo channel  seabash 40min cnc lathe vid https://www.youtube.com/watch?v=ZwOHX3pAYyg scrap to lathe chuck 40mins, by Isle Vlogs https://www.youtube.com/watch?v=94-RQ2gXa-4 channel my chu create shared by homemadetools.net https://www.youtube.com/watch?v=isVQMHmzHNo machine thinking channel https://www.youtube.com/watch?v=Y7OT4vFevxM channel wood to wonder https://www.youtube.com/watch?v=z67A3Myy6XM channel HOMEMADE MADNESS.
