If you want to cut the vibrations down, pour a concrete base to bolt the lathe to. Filling the voids in the headstock with concrete will help a lot too. And definitely add oilers to the bearings.

The lathe looks awesome! This is the first video I've seen of it(new subsciber). I hate to reiterate what everyone else said but I agree, those bearings need grease. They may not get as much wear as they would inside an axle but they will get worn out pretty fast. I'm not sure how an oiler system works but maybe drilling the bearing housing so you could use a Zirc fitting or something.

Keep up the great work. Im a new fan of your channel & seen the entire lathe build. Love it. To take some scrap steel & turn it into a useable tool worth a lot of money to buy even a used 1 is awesome. I generally build stuff i need for tools, just nothing as complicated as a lathe. I never imagined of building one either but you gave me motivation to maybe build 1 myself. Especially after seeing how much better you made it every time you did an important to it. And seeing how exactly you made some of the parts. I used 1 as a kid in school and loved making things with it. Maybe when I get my new shop setup i will try to build 1 myself. You get a pat on the back from me. Keep up the good work & awesome builds. Cheers for your future as a true machinist

Awesome lathe.You hit the nail on the head when you took the head apart.People use air to clear the teeth and it blows the chips Into the back of the chuck.Eventually it won't clamp down right.(I used to operate CNC lathes and grinders with pneumatic chucks.They'd get filled with chips and Not clamp tight,or true)Higher speed with slower feed equals less squeal.

good job!, but as others have already stated the bearings you have installed are often installed along with a oil/ grease seal on both ends to keep in lubricant and keep out contaminants so that you can get longer life, reduce heat buildup and friction. Grease will be the best bet for most of the RPM you'll be using, anything over 1500 rpms and a good gear oil is the way to. As for gearing, go with a large motorcycle transmission, some other DIY lathe guy used one, and you being a gear head, I figured that would be right up your ally.

Great job... The 2nd lathe I'm building will use concrete for the frame, I have a 3hp treadmill motor, I figured out the speed controller and it is quite simple, it seems to have quite a bit of torque at lower speeds, might add a 2nd pulley to gear it down, I am going to also put a treadmill motor on my small craftsman lathe to test out the tread mill motor, I get these treadmills free off of Craigslist, got about 5. I like your bearing setup, I never thought of it, I was worried about preload on my setup I thought about using a crush sleeve, for my oiling system, I am going to install a controllable drip system. The feed system I thought about using a stepper motor and control it with an aduino, don't know if it will be strong enough or fast enough. I'm playing around with adding an encoder to a lawn mower starter motor, of course I have to cast a housing. Looking at my craftsman lathe all the feed and speed for thread cutting is done thru gears even the reverse. I did print a 3d gear for my small lathe it's going on 3 years, don't know how it would hold up on a big lathe, may I can print the gear then cast it. All work in process, good luck and can't wait for the next video.

Leaving those bearings open so chips get into them is a bad idea. You need some oil seals on them. Chips, dust, dirt etc can get in there in NO Time. I have a question. Why did you use a solid shaft instead of a hollow shaft you could pass through for longer items? You can probably reduce your run out on that chuck by turning the mounting surface behind it again. You turned it then took it apart to make your adapter, put it back together without checking that surface again. Also you can take the chuck off, rotate it to the next set of mounting holes and try it again. That tiny amount can make it better or worse but you won't know until you try it. I highly recommend some sort of oil seal to keep debris out of the bearings and to keep the grease in them. I would have liked to see you test the run out of that metal piece you turned. It looked very good. Also you can grab that piece once turned and wiggle it up and down and side to side to see what kind of wobble you have in the bearings with the dial indicate on it. I really like this home made lathe. I wish I had one :-) Keep up the great work. Cheers !

Looking at the construction through the series i would now guess that some of the chatter is coming from the slides on the carriage not being tight enough. If it is possible, simple filling and shimming on the edge of the main carriage plate to move the sides in as close as possible to base would help with chatter and accuracy a lot. For a speed control an idea would be to use something like a quad or dirt bike gearbox from a blown engine for a gear drive speed control, after removing the cylinder head and piston, replace the flywheel with a pulley for a motor and then a simple sprocket and chain drive to the lathe spindle would easily handle the power. Being a machinist myself has made it relay interesting to watch the construction of this with limited tools.

If you drilled small detents in the shaft where the hub screws contact it, then you wouldn't have to tighten down the screws on the hub so much since they would now have divots to catch on in the shaft/spindle/Arbor (whatever we're referring to it as). That way you could tighten down the rest of the hub screws for clamping down the bearing assembly and not have to worry about the hub sliding out of place or being cranked down too tightly... hopefully that explanation makes sense... awesome video and great job on the lathe in general btw!

Use a power window motor & gear box from a car, forward n reverse all ready set up. That will get direction changes, maybe adding a DC potentiometer might get your speed for driving the "carriage " . Build or buy a four step pulley system, like a inch steps for both the motor n head stock. Multiple speeds there. Example 1725 motor speed 3-8 646 spindle 3-6 862.5 4-5 1380 5-4 2156. Changing the belt fast n easy. Build your steps as you desire , maybe a 2-12 for 287.5 rpm . As a boy we made a wood lathe with a 2" to a three step on a separate shaft to three step on the lath it self. Yes was a bit of work , the center block that held the second shaft was movable quick easy adjustments. Gave us many speeds.

The chatter marks is cause by slide not tight enough. Drill a square hole to secure a radius cutter on slide to cut/ hand plane, a radius race on each side of lathe way. Drill holes and tap on slide to put as many ball bearings as possible. Tighten balls bearing with set screws to act as gibs. Do the same as cross slides. If all slides are tight enough, chatter marks will be greatly reduced.

Cheap and easy way to adjust speeds.. Get a 2 speed motor from an evaporative cooler. Fit a variable speed pulley to it and have a spring loaded tensioner to take up the belt slack. That should give you a fair range of adjustment with minimal effort for about $100 - $150 all new parts.

your headed the right direction, but you need to do more. need to cover those bearings and give them an oil bath, id weld a tank between the two bearing plates(this will also make it stronger) to gather oil and make two cups to hold felt seals on the outside of the shaft. the cups will need a drain to a lower point or they will leak like a window screen so you will need a little low pressure pump to lift the oil to the bearings. also it doesn't matter what the outside of the chuck runs, only what the jaws run. normally on a tapered bearing there is a bevel washer that acts like a heavy spring, this will help keep your bearings adjusted correctly. if you want to get really fancy you might want to put a harmonic dampener in the middle of the spindle.

normally , when you want to reverse the lead screw there are 2 methods.. One is the machine is put in reverse electronically with a switch.. that's simple.. The other way is a reverse toggle which engages an intermediate gear next to the lead screws drive gear, this in essense reverses the lead screw while the lathe is running forward. This would be used for operations like left hand threads, and my lathe doesn't have that option.. A Third option Ive almost never seen for longitudinal traverse of the work is a power compound. this would have a motor on the top slide , and feed back and forth with no movement of the carriage .. Would be great for cutting tapers with speed.hope that helps

Part of the reason you're getting a lot of squealing is because you have a lot of stick out on your tools and were approaching from the side of the tool post, as opposed to directly pushing in with the post behind the tool.

You could get a better finish if you use high speed steel tool bits with 5% cobalt. Carbide is better with super rigid and heavy lathes. Also the tool should drag across the work and not be pushed across the work. Also the tool should have a small radius at the tip. And use some cutting oil. Also it's not too important if the chuck body has a little runout. you are more interested in how much play there is in the bearings. But if you get the play - side to side down below .001" tha should give you a nice surface finish. Also if the work material is not too hard it will improve the surface finish. Also you can use a variable speed motor from a tread mill. These are thrown away quite often on Craigslist or very cheap. You need the old style speed control with the rotary knob if possible. I'm running one on my Southbend 10K and it;s really nice. you also want to mount the tool in the tool holder deep. not much of the tool sticking out of the tool holder is the way to go. This gives the tool rigidity and fights tool chatter. Tool chatter is what ruins work finishes. Usually a very slow feed towards the chuck or away from the chuck is going to give you a better finish and a light cut with a very sharp tool. Good luck! Great job!

Last lighter cuts. You can accomplish this with a larger wheel / crank for both depth and lateral travel. Try a 12 inch wheel. Not just from four to six inch. But your handy, make and try them both. You said you are limited by space for your motor. Maybe vertical and horizontal slides are called for. Move your motor inboard, Possibly under to protect it from drebri. Run it 1:1 to a jack shaft, outboard. The shaft can then run out as long as you want. Where pulley stacks can be added to both drive and driven side. Of course coming from farm country. Go look at the variable speed drive on an older combine. To big for your shop but I bet you can machine your own. 1. Bearings = grease, nuf said. 2. Shield that motor and fan or it will look like the inside of the chuck. 3. Cutting tools mounted close as possible to tool rest. I came to your videos because I wanted to build a wood lathe. I stayed through all 13 episodes in admiration of your talent and skill. Hopefully it makes me better in my endeavours. Will be interested in seeing your changes / future improvements to your lathe and future projects. Best of luck. Ken, from Nebraska

End caps to set the bearing preload and to hold grease seals are required. Don't worry about grease in the bearings the bearings will let you know when its needed, probably very soon.

I noticed that You have not changed Your Support for the lathe bed. I have been machining for 30 Years and one of the first things I learned was to make sure that the lathe has be bolted to a rigid support structure ( solid metal ). This will give you better machining outcomes and save the bearings from premature wear / failure. It lessens vibration etc .....

A FEW SMALL SUGGESTIONS FOR YOU....... 1). NEVER USE YOUR HANDS TO REMOVE THE SHAVINGS- period. 2). USE OIL WHEN CUTTING ANYTHING. 3). GET A SOLVENT TANK TO CLEAN PARTS WITH..................... THEN GOOD TO GO !

adding variable speed gears isn't all that difficult, and a really good way to see how it's done is to watch all the videos on here on making the Gingery lathe (a home made lathe from parts you cast as you go). The lathe itself is a little flimsy, but the gearing principle has been the same for lathes of all sizes since the industrial revolution - well tried and true, just about as simple and reliable as you can get. If you can't make it out from the videos, the book by David Gingery has a really good explanation and calculations for pulley sizes and speed ratios. I'm sure you will find when you can spin your job much faster the finish will be mirror-like. And yeah, I can't help myself either - as others have already said: put oils seals on both sides of your bearings ASAP or they will be crap in no time, and for god's sake - pack them with appropriate grease.

very cool....but i wonder if isnt better to screw that bearing thight with a ring screw.. but its awesome! greetings from brazil!
