$200 Dividing Head - Almost Scammed Buying It

  Bought the same one about a year ago. Undid the chuck bolts with pliers (not very tight). Didn't realise the back plate was screw on until I had the chuck off. Undid it with a little bit of force as it was a bit snug. I did actually put it back on a bit tighter as I was worried it may loosen up during use. Worth getting apart and redoing the lube. Works fine enough for the money.

  to try to get the chuck off, you can put a piece of hex bar or large nut in the chuck, then use an socket and impact gun on the nut while using a strap wrench on the manual index plate to hold it. This works a treat to get my lathe chuck off after I had it jammed it on for years that tight that I broke my back gear try to undo it.

  Those &quot;t-nuts of some sort&quot; are intended to be keys to register the head against the t-slot in your mill table, so you can r&amp;r it without spending a lot of time on getting it square to the table. I&apos;ve got the same head, and it&apos;s pretty convenient- the spindle threads are the same as on my Atlas lathe, so I can take chucks and workpieces back and forth between the mill and lathe with no problem. (Especially convenient as I have 4-5 different types of chucks that I use on the Atlas.)<br><br>Edit to add: I&apos;ve never had any trouble removing the chuck from the spindle. Not sure what&apos;s going on there for you.

  Looks like a good deal.<br>As for getting those odd divisions I&apos;ve relied on compound indexing. It&apos;s described in the Machinery&apos;s Handbook, and includes a chart for all divisions up to 250. I don&apos;t know if the latest copies include it with all the modern ways of doing things, but the 16th and 21st do. Essentially, it involves having a second indexing pin attached to the body. With this setup the handle can be indexing in one hole circle, and the plate indexing in another. The mounting bolts in the plate will need to be out, and the center hole should be a reasonable fit on it&apos;s mounting. <br>This isn&apos;t a new idea. My first dividing head patented in the late 1800&apos;s is set up for this. (I&apos;m old, but I didn&apos;t buy it new.)<br><br>A footnote below the MH chart reads:<br>&quot;The indexing movements are exact for the divisions marked with an asterisk (*); the errors of the other divisions are so slight as to be negligible for ordinary classes of work, such as gearcutting, etc.&quot;<br>Years ago I calculated the accumulated error for 51 divisions. At the crank it amounted to about 1/50th of the center distance between two adjacent holes on the 47 hole circle. &nbsp;I&apos;d say that is less than the accuracy one can expect from even a quality DH.

  Do not press it out. You need to unthread the chuck backing plate. If you press it you will break the retaining screws holding that cover plate. The brass gear inside is held on with a threaded nut, it isn&apos;t going to be pressed off. Bolt it down, use the index pin and the spindle clamp to hold the spindle shaft from rotating, wedge a long piece of wood &nbsp;in the chuck jaws and unscrew it. It is just on tight, it isn&apos;t welded or pinned.

  I see how you’re able to get it for about $200. I’m in the USA and that puts the price tag over $330. Guess I’ll just wait till it’s more convenient. Good video sir 👍🏻<br><br>Edit: Well, I waited and recently ordered one from AliExpress for…are you ready for this- $180! I’m super stoked 😆

  You get what you pay for, but with careful setup you can do great work on it. Not heavy duty boss crashed ours and cracked frame but we were able to weld it up . But he tried to index a 8 inch dia backing pusher and got in a hurry and hogged the part and bang. I would buy one they are well made for the price. For home machinist they are fine. You could save money and build a Gingry index head yourself. His series of books are very interesting.

  Really well done. &nbsp;I got the Vevor lathe and had a good experience with them as well.

  The original B&amp;S dividing heads have Timken type zero taper roller bearings, and the spindle nose and taper are ground true in place in those bearings. Disturbing the bearings for any reason is risky. The spindle will lose factory accuracy because of stacked errors reassembling. I found the imports a great buy, but the items need refitting of the parts. Good video showing the problems.

  The thing at <a href="https://www.youtube.com/watch?v=rtgESIVpUPo&amp;t=95">1:35</a> that you’re not sure what is, it attaches to the dead center and is an attachment for a lathe dog when turning between centers.

  It looks really good for 200 bucks

  I just bought from Vevor. The order says 1-6 business days shipping. My guess is it will be a bit longer. I do live in the states. Not sure where it ships from. I purchased to assist with building a simple cam. Once I get it I&apos;m certain I will find other uses. Thanks for the review. Was happy to see someone else had good experience with Vevor. I bought the 8&quot; rotary table as well. I&apos;d definitely like to know how to get the chuck off as well.
