    Hey Winky! A good way to avoid issues while drilling brass and bronze, is to use a oil stone and stone a little negative rake on the face of the cutting edge of the drill bit. It won't take much and sure makes life easier. Use a little cutting fluid while drilling and you can control the drill bit easily. I used to keep a full set of negative rake drills, taps, and counter- bores for bronze, along with a full set of bottoming drill bits and taps. Thanks for the video as always!

    Great job Winky. I replaced the nut,s on my mini mill with sintered bronze, and lengthened the nut 1/4". I sacrificed a little travel, but gained stability. For now there is less than a thou backlash which I discovered is in the thrust bearings.

    I made a new cross slide leadscrew nut out of bearing bronze for my lathe. I ended up buying a 30cm bar and just chopped a section off it with a bandsaw. Then machined it on my 4 jaw.
    I then just used an M10 x1mm tap.
    It feels so much smoother than the stock brass one, and I know bearing bronze will wear a lot slower.
    Its worth spending a little time improving your lathes cheaper components, especially when they are easy to make.

    • @WinkysWorkshop
      @WinkysWorkshop  Місяць тому

      Bronze is better, how much is hard to say. The bronze use in bearings is usually not ideal (sintered) but some are solid. I haven't noticed any wear yet and my screw was near perfect.

    You keep at this you will have a better than new lathe. I am surprised you chose brass. I thought TQ100 hot plate would have been a beter choice. It is highly machinable with great wear resistance. Brass is slippery enough but I suppose the wear has to happen somewhere eh. Either wear the screw or wear the fitting. You made a better choice my friend. You sure solved the backlash and now time will tell all on your material choice. I am thinking your on the money my friend. Hmm, I was always taught to work cast iron dry with min rake on the tools. Same speeds and feeds as stainless. Great results my friend.

    • @WinkysWorkshop

      Brass is easier to machine and better than steel for wear plus it's fairly strong. I'm sure some sort of bonze would be better but I'm not sure what type.

      @@WinkysWorkshop When I was making silver chopsticks(.925 Sterling)(I have a couple video's on them) It was necessary to toughen up pure silver so the sticks wouldn't bend out of shape when being used. I was originally using copper as the alloy but was having some difficulty with getting the metals mixed so no copper would show. A good friend suggested I use zinc (another soft metal) so I went primarily with zinc and a touch of copper and brass. I had to pour the mix a total of 5 times to get it properly mixed. I am still amazed at how tough the mix was/is. Effort is needed to cut the 1/4 x 3/16 in sticks with a 18 in pair of bolt cutters that if the mix was pure silver a 12 in bolt cutter would easily snip through them. Perhaps a copper/zinc alloy would work for you in this case. It would be easy enough to pour a block of it. Possibly a new project for you when you have nothing else to do, LOL. In the spring I can put a pour of it together for you for fun. It would be great to do a small project together. I would just need an approx. weight and rough casting sizes. I would think an 1/8" on all sides would give you a nice clean piece when finished. I still can't get over how 2 or 3 soft metals will make a really hard one. A while back a pourer called "Backyard Bullion" from England and I did a trade. He did a really nice video on the sticks.

    Nice job. I recommend that you drill a hole in a screw that you made and a small hole through the nut that you made so that you can oil that nut and you will get a lot more life out of it. That's the way it's done on a standard cross slide from south Bend.

    Great upgrade to the South Bend lathe! I did the same operation of my English Smart and Brown SABEL lathe that is clearly a development from the South Bend lathe. Couple of things spring to mind. When machining cast iron it is usually best to cut it dry, the graphite in the cast iron acting as a lubricant. Listening to the milling cutter it sounds as if it was stop/starting in the cut which the lubricant could have made worse.
    You can avoid brass grabbing on a drill and pulling it into the cut by grinding a negative rake to the two cutting edges.
    I made my cross slide nut from phosphor bronze and with no tap to hand, internally screw cut the left hand square section thread. With only the one lathe I had to make a dummy section of male thread to use as a plug gauge when screw cutting the nut. On the SABEL the lead screw nut has a close fitting boss locating in the slide and to clamp uses a slotted head set screw with 45 degree tip that drives out a side pin. The side pin sits in side hole of nut and is radiused one end to match cross slide bore and other end at 45 degrees to bear against conical end of set screw. My set screw slot was worn/damaged so I made a new one. Slot I cut with slitting saw, plunge not traverse cut which is what machined screws usually were before they went to cold headed slots.

    Hi Winky, I've done my share of tapping and also had my share of the dreaded broken tap when tapping small holes. I always use the accepted technique of backing out the tap a half to full turn often to help clear the swarf. I noticed that you also used this technique when you were tapping the Acme Cross Slide Nut. I mention this because I keep coming across UA-cam posts that say never back an Acme Tap up or out. Since I'm going to be Acme tapping too I don't want to make any mistakes. I can say that looking how the Acme tap is tapered I can understand why it should be fed completely through the stock.

    Lots of people making them. I did so as well a few years ago but made mine out of MDS infused nylon instead of brass. It is easy to machine and works great! This material has a lubrication factor built right in. It will outwear teflon in extreme conditions 100 to 1. Also you can drill a pilot hole all the way through a brass one, then drill a hole all the way through the bolt and use this to directly oil the screw.

I simply can't believe that SB - or any other manufacturer of industrial machinery during that period - would produce a product with such a glaringly obvious (and easily avoided) design flaw.
    ...I have an 11" Logan (model 955) lathe that came to me with a couple of similarly bone-headed "repairs" that I've had to re-repair in ways that made more sense.

    At 11:00, for brass and other soft metals it’s about the cutting edge, not the speed. Grind a wee bit of a land on that edge, at 90 degrees to the work, so that it takes a scraping cut. Of course, that dedicates your bit.

    I drilled the screw hole through until it was just breaking into the acme thread and tapped it.
    Then I stuffed half of a cigarette filter into the hole. I saw this on one of the machining forums.
    When I mounted the nut, before I put the grub screw in the top, I filled the hole up with oil.

    Play/ backlash is inherent in any normal thread. With a conventional lathe, the play is always moved to one side so it's never a problem. CNC is a whole different ball game although the same principles apply. A really useful feature is a locking mechanism on any slide not in use for the operation at hand. If you don't have it invest time there. We have a Colchester Triumph 2000 lathe at work which I found has a very nicely executed locking mechanism for the compound, also the saddle can be locked. I have yet to locate the cross slide lock.

    Think of this. Use a tap Drill to drill 2 holes across above the acme thread on either side of the 3/8-16. Counter bore the holes for button head Allen's. Use tiny belville springs or high compression rate springs only 1/4" or 5/16" tall. Cut an angled slot from the top beside the stub sticking up into the upper acme hole. Now by varying the button head tension you can vary the grip on the cross slide screw automatically. You may end up boring a little out of the acme hole to allow it to contract on the acme thread angle instead of bottoming out in the root on the screw.
    It's just a thought depending on how worn your lead screw is. You could also slip some wick felt into the slot to oil the lead screw. Drill and shallow tap a hole in you cross slide for an removable set screw to oil the felt once In a while. Again. Only a thought.

    • @WinkysWorkshop
      @WinkysWorkshop  4 роки тому

      Thanks for the input. I'm not sure there is enough room to do this although I might try if the nut starts to wear. Currently the amount of backlash is very slight and even slightly tight on one end of the travel. Also, when I ran the tap through the nut again it opened a small hole between the mounting bolt threads and the acme. I think I might drill a small oil port in the mounting bolt.

      Several others have said the same about bronze and I'm sure it would be better. I'm guessing brass will wear better than the original cast iron and it lasted 90 years. Brass is used in car water pumps and boat propeller shafts because it resists corrosion better than bronze so I'm sure it will be adequate.

    @daveticehurst4191 4 роки тому

    Winky, you really did not need to make a new shoulder bolt, as the nut was now located inside the original 1/2 " hole in the cross slide. All that was needed was to retain the nut from dropping out when you removed the cross slide in the future. You could have just countersunk the cross slide 1/2 " hole and fitted a standard countersunk Allen screw or even just a slotted soft screw. The Manufactures only used a shoulder bolt to take the load on the nut, you now have no load on the new nut as it is now located in the 1/2" hole. Tip for drilling brass / Perspex ect. to stop the drill grabbing, is to "back off" the cutting edge with a few rubs with an oilstone. This is to make the drill a NEGATIVE rake tool. As an accomplished woodturner, you should know this with your negative rake scraper, and found out that a standard tool will grab. Another great project and video under your belt, well done. Thought, should you want to reduce the backlash you have, make a thin nut say 1/4 inch thick and fit a compression spring in between it and the original nut. That will keep a tension between the leadscrew and the nut at all times. You may need to add a tiny anti rotation pin between the original nut and the "washer nut" otherwise it could rotate slightly and jam in the saddle. If you have a 3 d printer, you can see the idea on the Z axis . Stay Safe and Well.

    • @WinkysWorkshop
      @WinkysWorkshop  4 роки тому +1

      I thought about that too. I should have made a longer extension on the nut. Still I feel a little better with the steel thread going into the brass and nut. There is a lot of force on the brass, if nothing else I think it would get loose over time. Also the way I did this is just like the later model South Bend lathes. I wonder if lower RPM would have helped the drill and the mill grabbing. I'd hate to blut the edge of my drill for one hole.

    Great project, nicely done! Taking out the backlash is a great result. I don’t see why you had to hide the top of the bolt, though. Is it because the compound would not swing even 120 degrees? How did Southbend never realize that folks would be threading things internally?

      @mradtke66 4 роки тому

      Not being able to swing a compound 360 degrees is odd, but you don't need to swing it so far to thread internally. For normal, right hand threads cut by moving the tool toward the check, swing the compound 30 degrees to the right. Advance the tool with right hand turns of the crank, pushing it into the work (I know you know how to do this, just setting the stage for step 2.)
      For internal, right hand threads, swing the compound 30 degrees to the left. Advance the tool with left hand turns of the crank, "pulling" it into the work.
      As an added bonus, it keeps all of the controls on the front of the apron. Reaching over the ways to dial in a cut for threading seems silly to me.

      Take a look at the handle/dial. Not knowing exactly what you have I can't look at a parts diagram, but the Logan lathes depend on adjusting the inner nut as tight as possible while retaining free rotation then tightening the handle to the inner nut. I use a very thin bicycle hub cone nut wrench to hold the inner nut.

      much, much better now. .007” vs .018” of backlash. I wish I can
      completely eliminate it.
      What do you think about making an anti-backlash nut by using maybe one
      third of the old cross slide nut (I call it the tension nut) and
      bolting it to the new one with a spring in between them? In my case I
      would use a 1/2" dia X 3/4" spring outside the lead screw and two #10
      bolts (in the area above it) to bolt the tension nut to the cross
      slide feed nut

I think a anti-backlash nut of some type would help but I'm guessing you will always have .004" or more. I'm not sure it is worth the effort. I've seen people modify the nut by cutting part way through (as if you were separating the nut it into two nuts) and adding a small set screw that separates them at the cut. The uncut section flexes a little and removes the backlash when you tighten the set screw.

    Nice fix for something that should have come that way, you can make the brass nut adjustable by drilling and tapping 1 or 2 holes either side of the leadscrew longways for small capscrews then cut a slot crossways about 1/8" in from the end almost right through when you screw the cap heads in it opens the slot slightly making that part of the thread slightly wider and hence it takes out backlash. Almost all the chinese mills/lathes use this method.

    Where on earth did you get a left hand Acme tap (in 1/2"?). Not many machine shops would have one of those!

    Curious why not use a flathead countersunk in the casting ?

    • @WinkysWorkshop
      @WinkysWorkshop  4 роки тому

      A flat head screw would have worked although the shoulder bolt probably increased the strength a little. I basically copied the newer SB design.

    I'm just a hobby machinist so maybe finding center with your six-inch steel rule is commonplace for others. But not for me! I know you didn't explain the process you were using to get center as it wasn't really any of the point of the video, but thanks for leaving it in.

    Could you please tell us what the ACME TPI and also where you sourced the Acme Tap

    • @WinkysWorkshop
      @WinkysWorkshop  4 роки тому +1

      I got the tap on eBay. It's a LH 10 TPI x 1/2" Standard Acme. So far my all my lathes have used this size in the tail stock and cross slide.... the compound might be 3/8" but I'm not sure.

      @@WinkysWorkshop Thanks for the quick response. I need to do the same on both of my clausing lathes. I found a guy that sells the Southbend nuts but i will need them for my Clausings. If the tap is priced reasonable i may just buy the tap and make them myself. Again thanks for the reply and the video.

    I've seen other machinists bring up the knee/table to prevent grabbing. If quill is locked bit can"t be pulled in.

      You are right, I absolutely should have locked the quill. Excellent comment, thanks

    Hi, i noticed you've used a parting blade for normal turning, is that recommended? Or is that some special tool that i'm not aware of? Thanks for the video.

    • @WinkysWorkshop
      @WinkysWorkshop  3 роки тому +2

      It's called a grooving tool. You can part with it but it also cuts side to side. They are great for cutting a square shoulder.

    Nice job. I need to do this also. How did that brass nut hold up?

    • @WinkysWorkshop
      @WinkysWorkshop  2 роки тому

      It's holding up very well. Most the backlash is at the dial. Ideally a set of thrust bearings would be helpful but space is an issue
