  • Chuck for turning laege parts.

    While enjoying Evan`s lathe build I got to thinking I could use a way of turning some large parts.
    So I set in to day to build an adapter to mount a extra 8 inch chuck I had to my Van Norman mill For turning short but large dia parts . It is possible to do 36 inches but I think 24 inches will be enough. I set in to make and adapter to fit the 5v spindle and 1 1/2 8 thread chuck .A piece of 3x5 ETD 150 was rounded op and turned in lathe to fit . Being the 5v spindle is so small and not wanting such a heavy part hanging on it ,I counter bored it so 1/2 inch of the adapter would just slip over the nose of the spindle for added strength. Here are some pictures
    Next I will make a column to mount the compound of my South Bend lathe and tool post on. Any thing I will do can only be about 8are 9 inches long ,but should not have any problem with diameter and I can slow the V.N. way down well less than 50 RPM We will see what will happen . Again thinking out side the box.

    We have a Horz. mill with a 12 inch chuck on a 50 taper. It will swing 50"

    its a bit spooky but we just slow it down and run it unattended with stops set.

    Its not a great lathe but it will take a fine cut to true up a warped part.

        Lane, Could you post more pictures of your Van Norman with the 4 jaw on it. I have an old Van Norman #12 setting in the corner of my shop that I have been wondering what to do with it. You have come up with a good idea and may have saved its life!

            You could save yourself all that trouble and just give it to me...

            I would also like to see more pics of the mill, purely for aesthetic reasons!

                Have the same adapter and compound post that mounts on the table on my little Tom Senior mill. Use it to machine two in one sled cylinder heads. Also have ground a couple of flywheels with it. Peter

                  Are you sure your mill has the RIGHT bearings in the spindle?????
                  I just need one more tool,just one!

                    Consider this thread hi-jacked

                    I did something similar about a month ago for use on my mill. I don't remember the maximum swing, but I think it is in the neighborhood of 30". You did some nice work on your's Lane, but I used more BILLET, and if you look closely at the pics, you will see a liberal sprinkling of transparent aluminum throughout.



                    This seemed like a practical project, but I really didn't know how soon I would use it. About a week after it was finished, I cleaned up some brake drums for a buddy that wouldn't have fit on my lathe's 11" swing.

                      -Actually, I was going to suggest something similar to Evan in the original build thread; not as an alternative, but an option. I'd seen a similar mod on another board, and Evan already has a decent, albeit somewhat small, horizontal mill.

                      But after seeing his responses to other suggestions- as in, ideas that weren't his- I figured he'd just tell me he'd already thought of it on his own, and dismissed it as unworkable for some obscure reason (usually boiling down to some variant of "if I didn't think it up, it's therefore not worth doing".)

                      Snark aside, I've been thinking about a very similar idea ever since seeing that mod. My Nichols has four 5/16" tapped holes on the face of the spindle, as it simply used capscrews as drive lugs. It'd be dirt-simple to make a small plate that bolts on, then face it off. After that, just drill and tap for whatever large diameter job you have.

                      Or make a 40-taper adapter; Only about a month ago, I saw one listed on eBay, probably a homemade. NMTB 40 with a lathe spindle thread- I think 1-1/2"-8. I could make one threaded 2-1/4"-8 to take the chucks or faceplate off my Logan, and theoretically turn... probably at least 30", if not 36".

                        Lane, Thanks for the pictures. They answer a lot of my questions. I got the VN #12 years ago as payment for some work but have used it very little.

                        Thanks again, Norm

                          Right wrong are otherwise it has plain old wheel bearings. How I know is I put them In their.
                          Every one makes too much of a fuss about bearings . and from plenty of experience with them It does not make that much difference. Class 7 in a grinder any thing else will work in Lathes and mills. How I know Is I have DONE IT. I did not come in on a turnip truck.
