In this video, I make a chuck back plate for a plain back 5" 4 jaw chuck. This is an interesting bit of turning, because I needed to use the face plate for the initial turning steps.

Thanks for the video, I planned to mount a 5" independent 4 jaw chuck for my Harbor Freight 3-IN-1 Multipurpose Machine 44142. You gave me some interesting Ideas. Fortunately I don't have to make a adapter plat as the recessed area on the back of the 5" matches the raised boss on the HF exactly. I just need to cut four holes into the chuck to mount the bolts, hopefully without cutting into the jaw channels etc. Thanks again for the video I found it very helpful. Best Wishes n Blessings.

Set-right chucks use radially mounted setscrews and a bit of radial clearance to fix the last couple thousandths and tenths of out of round. You can also just loosen the back plate a bit and tap the chuck body into round.

using oil when machining cast iron will make it hard to protect the ways on you lathe. you can machine cast iron dry and catch the dust and chips with a cloth covering the ways, then vacume the machine clean.

@miguelnavarro3830 7 жыл бұрын

You are very right on that...!! No lubrication with cast iron. You may want to use a good mask while working cast iron, other ways you will have black nostrils for long time.

@mikemarler8224 7 жыл бұрын

Right-o. Cast iron is self-lubricating, due to the graphite content. When you machine cast iron, the fine powder gets everywhere, and adding machine lube or oil makes it much, much harder to get out of all the nooks and crannies.

Great video! Thanks. You deserve some better machines though. A boley, weiler, schaublin lathe and a deckel or aciera milling machine would be more fun. But I must say that its more impressive with guys using what they have and make it work super good. I like seeing people taking a cheap ass chinese lathe or mill and scraping it to be almost as good as the premium machines. Just a thought. I’m about to make a plate just like that for a short taper flange to my 380mm 4jaw. Is it necessary to use cast iron for an adapter plate? Or will steele be good enough? On my other lathe I got the long taper fit. It seems more precise than those short taper that arent actual taper fitment at all. Its just a tapered guide for the chuck to slide on more easily, but the chuck could move within the tolerance of the center hole, unlike the long taper that always centers the chuck due to the taper fitment.

@Dans-hobbies 3 жыл бұрын

Sorry, I didn't respond sooner, I've under the weather for over a week. You can use just about any material you like, I've seen people use aluminum before. The main benefit of cast iron is that it's a good middle ground. It's easy to machine, it has good vibration damping qualities, and it is usually softer than what your spindle is made out of so you don't have to worry as much about damaging your spindle.

If i understand you correctly, yes. My spindle is designed for plain back chucks. The basically means the spindle has a boss used to locate the chuck, and then bolts are used to secure it to the spindle. This method is very common on small import machines, as it is cheaper to produce than a cam, thread, or taper lock.

4 jaw chucks don't have a scroll, so you can actually just machine a ring that fits inside the chuck recess with an ID that matches the spindle boss and then drill and tap for 3 studs and your 4 jaw will bolt up just like the 3 jaw- done in 20 minutes and no adapter necessary.

Question: how did you know that the sawn side initially clamped to the faceplate was truly flat? 'Cos if it wasn't, then the side that you machined flat wouldn't be when you released it from the faceplate.

@Dans-hobbies 2 жыл бұрын

It doesn't need to be truly flat. It just needs to be flat enough that it can be securely held to the face plate for the first operation. If you want to check if a part is flat enough, the best way to do that imo is with some sandpaper adhered to an old or cheap surface plate. Just give the part a few lapping strokes and look at the scratch pattern left on lapped surface,

@Dans-hobbies 5 жыл бұрын

I'm not a professional or an expert by any means, but what i was told from other people I trust made sense to me. You want to use something softer than what the spindle is made out of, that way if something goes wrong you are less likely to damage the spindle. I Have seen people use aluminum , but cast iron has better vibration dampening qualites.

The big one is that it is much better at dampening vibrations, and thus can help minimize chatter. The other main benefit, is that it is softer then the spindle, so if it gets dinged up in use, it's less likely to damage the spindle.

I just want to build some experimental metal lathe, most difficult part is to make that connection between chuck and motor. Car wheel bearings should withstand the forces? If i think how much movement and stress the tire makes for the wheel bearing, when turning, on the bumps etc...

It would depend on your lathe and how it mounts chucks, as you need to have enough thickness to clear the mounting hardware. The best thing you can do is sit down and sketch something up on paper or in cad.
