    Sometimes you'll speak of being able to "intuit" something. As a newbie, my intuition is often wrong, even 180° wrong.
    Watching you work, hearing the explainations, absorbing your reasoning is developing my intuition. Am beginning to 'see' the next step, or visualize a process, even before ever doing it myself.
    I know that watching isn't doing, but watching is learning (and often laughing; you've a great sense of humor. Utterly lacking in other videos & much appreciated), and so I wanted to tell you that you are building in us new folk that sense of intuition which appears a valuable tool to have in this lathe quagmire.
    Thank you so very much.

    I use a plastic disk with 4 or 6 holes and bolt with nut in the middle of plastic disk + electric screwdriver for fast compound movements. It has much better centering and less vibration than T-shaped adapter. Also it can be used on cross slide. Also it does not damage lathe handles, because the disk was made of plastic.

    Good info, well presented as usual.
    Two more:
    1. A variation on the scaling setup is to deal with the imperial-to-metric thingy with appropriate compound slide angles, and
    2. Mounting your compound slide on your milling table in various orientations (think angle plates) and the part in the spindle can open possibilities.

    @terrybailey2769 2 роки тому

    I enjoyed the video and learnt something new as usual, thank you. Incidentally I use the trick of locking the carriage with the leadscrew nut as I don't have a lock on the carriage so the compound gets used for a lot of cuts. I also made a angle plate for 14.5 degrees so I could set the compound against the face of the chuck easily, squeezing up on the end of the compound that with the compound angle unlocked sets it up perfectly. It is just a case then of tightening the lock nuts.

    I will be sure to recommend this video to lathe newbies. I learned lathe operations at my technical HS but the 14º offset trick is new to me. Thanks! My tip: I use a Sharpie to mark the positions of my compound and cross slide at "0" so I don't have to count my handle turns when backing out. Also keep a small bottle of alcohol and a rag handy to erase the marks.

  • @prodoverjeff2876
    @prodoverjeff2876 2 роки тому +2

    While not as experieced on lathes as on other machines, I did learn the compound was my friend. Rigidity was an issue on a South Bend that was older than me, but I did figure out the gib adjustment, and sometimes made a cut while pushing a finger on the tool holder. (Certainly not the best precision, but when criticality was low enough, and time was short, it worked).

  • @brucematthews6417
    @brucematthews6417 2 роки тому +1

    That was a great and highly informative tour of the compound. Happily added to to my "likes". And particularly with the hints on the reach aspects. It's not just the small lathes that can run into such issues. And consider that even if one does make a solid riser it's not like the compound cannot be swapped in and out as the situation requires.
    I ran into the same issue with the degree scale not being the full 360. My 12x36 size lathe angle markings only goes around to plus/minus 45 and originally came with only a single "0" hack mark. I added additional hack marks at plus and minus 45 and 90 to the cross slide top. And later on to allow swinging right around as you demonstrated I added more marks at 135 and 180 on the tail stock side. An initial light scratch mark followed by a light tappy-tap-tap with a small purpose ground cheap cold chisel and light hammer finished the very helpful job. At times the work can also be in the way of the proper zero mark too. So having the additional hack marks comes in handy in additional ways.

    The compound on the lathe is a good layout tool too. The face relief angle on most right hand lathe tools is pretty shallow, so setting the compound on a 90 or 45 can give you a good sharp scribe line. Good for crappy castings too to see if the material will clean up.

    Joe Pie has disproved the myth that setting the compound at 29.5 degrees allows the single point tool to cut on the leading side only, his point is that it has to cut on both sides or you will not get a good finish on one side of the thread. Thoughts? He did a video on this subject which is quite convincing. This video of yours is VERY good........ thanks

    One important thing you may have missed - When you are indicating on that dead center that is chucked in the lathe, you need to make sure it is running true, and especially be careful that the indicator tip is on center vertically (ie. at the lathe's spindle axis vertically). Otherwise your angle will be off. You can find that point by leaving the quick change dovetail (the one that is holding the indicator) a bit loose and sliding it up and down to find the highest point, keeping pressure back on the toolholder so there's no slop in the reading. Then, lock it in place there.

    another great tip for using the compound for tapers. Use a Boring Bar and turn in reverse on the far side of the part. I use this technique all the time for great taper finishes, and I can keep the boring bar at the same 90Deg angle to the workpiece instead of matching the taper angle. I always finish the diameter in reverse feed also, its just easier to keep it steady

    If your lathe can run clockwise you can work on the backside of the part, if not you can still work from the back by turning the tool upside down.

    Very nice video as usual. The angle block demo is sweet, and using the cross slide zeroing with the compound for feed is a really neat idea.
    Not that this is recommended but you can also loosen the compound and swivel it during the cut to form shallow concave/convex hemispherical cuts, like a very limited ball turning tool. Stressful on the machine and somewhat risky for the user, much like a ball turning tool.

    You must be psychic...! I am in the process of building a sort of compound on my home made lathe, not really understanding the functional requirements... Now I know better and will rethink everything. Thanks for saving me (again)

    When I was younger I worked for John Martz Luger carbine maker from Lincoln, California and I would make sling ring reproduction parts. The one that went into the buttstock had wood threads cut into them. If one looks at wood threads they start on the end at a point then, quickly follow a radius to the tapered shank. I created a jig which worked with the compound of my lathe so the threads would begin cutting at the tip of the sling ring shank and would follow the curve to the main taper of the shank and lastly pull the threading tool out of the work at the finish end of the thread. The threading tool was a standard 60° tool with an angular flat ground into the end of the tool. When all was working properly and I had to sharpen the tool often; it produced a beautiful wood thread that was part of the sling ring mount. After creating the thread, I would take the part out of the lathe and put it into a 5C Square collet block and machine the rest of the part in my Lagun milling machine with a form tool I made. I also had my own tool sharpening / grinding capabilities on a pedestal tool grinder and would put a microscope on the post and grind tools under the microscope. I made alot of form tools both lathe and milling cutters in HSS, M2 and carbide.

    The 14 degree compound is ancient lore. Some of the old Cincinnati tray top lathes had a detent at 14, 29.5, and 84 degrees (at 84 degrees .001 compound =.0001 cross)

    This gave me flashbacks to SB's How To Run A Lathe, had to go dig it out and if you set your compound to 84 degrees, each .001 of compound travel translates to .0001 of cut. (Pg 42 in 55th ed.). Love your stuff!!!
