You did very well in the end, its not easy to screw cut & video at the same time. I like to make a gauge same size as spindle thread saves taking chuck off & some day it will come in useful for something else to screw on there, just watch those fingers 🤌!

Hi, Mark. I also use that method of letting the carriage stop slide freely until I establish the depth I'm boring to and then lock it up tight. I also use a digital depth reading scale made from a 6" digital caliper that clamps onto the front vee way and the sliding part attaches to the apron side face with a 10mm neodymium magnet. Once zeroed from the start point of the cut it provides a really reliable indicator of depth the boring tool is into the job. As for difficulties you had here with the external thread and tip breakage I often find problems with carbide threading inserts when cutting deep thread forms on low carbon steels such as mild steel. I find better cutting reliability and less galling and digging in with a good quality piece of HSS Cobalt tool steel ground to the required profile angle. Carbide inserts are very fragile and prone to fracture when confronted with low spindle speeds and gummy material such as mild steel.

I totally agree about the inserts however in this case it was from the lathe stalling. There is also a drastic difference in inserts especially when you buy very cheap Chinese inserts. I use a common DCMT diamond insert a lot. I was doing okay with ebay inserts and then one order I got was total junk. I ordered from a different supplier and had the same problem. So I ordered some OSCARBIDE on amazon at about double the cost and they work great. As for the indicator, I'm sure that helps a lot. I think I may just get a DRO for the carriage. it would be very handy. I don't mind dials on a lathe but on the carriage the dro would be great

NEVER put your finger inside a a part turning in the lathe to do anything!! People have lost fingers like that! All the best, Matthew

How many HP do you have on your lathe? My 14x40 has 2 HP and if I crash I break tools, I have never stalled it. Insert breaking if you stop in the thread is almost 100% guaranteed. Some days just go like that!

@WinkysWorkshop

16 күн бұрын

Yeah, you are right about the inserts. My lathe has a huge motor but it's only 1/2 hp. However, I have never stalled the motor, it's always the belt slipping. New belt is now installed and I modified to add tension.. ,, so it should go better in the future.

Winky, you are 100% correct. Taking too big a bite for the size of equipment. With a 12-13" hobby lathe, D.O.C. should be no more that .005-.007.

@WinkysWorkshop

I was trying to take .005 and .003 when the inserts were breaking. I replaced the belt after this video. I also modified the tension setup. It will not slip as easy now. I suspect I got some oil on the flat belt also.

Some days are just harder than others. Thanks for the video keep on keeping on.

Every project seems to have its challenges. My issue is that you are taking an incorrect approach - not in making an adapter, but in your concept of using a chuck from a metal lathe to hold wood. You should either buy a wood turning chuck or make top jaws for your chuck from your metal lathe that are better suited for wood. Look at a catalog. Lots of ideas for an even better project. Thanks for your regular videos. Great entertainment and inspiration.

The chuck I had was intended for wood. Most the woodworking chucks simply have more surface area and will grip a curve. The curve is something I don't need to do. Before I sold my Logan I used the metal lathe chucks and they never failed me. It would be nice to have different set of jaws with more surface area.

Hello Winky, that was very challenging, thanks for sharing, cheers from me. 😃👍👍👍👍👍

When you took it out of back gear you didn't loose your timing on the threads. The spindle to lead screw timing doesn't change. The only time you loose timing is if you disengage the reverse tumbler.

You are right! I hate it when I have a double brain fart... but thanks for pointing this out.

Check the backlash your cross slide and compound. It may be just enough to cause your tool to dive into the workpiece. I have that same issue with my Atlas. I now use hand ground HSS threading tools to reduce tool pressure and tight gibs (not ideal , i know) on both the cross slide and the compound. That seems to help overcome the inherent flexibility of the lathe. Your South Bend is much stiffer but maybe some zero backlash nuts will help. You’ll have to make those. All this is if new belts and good belt dressing don’t work.

@WinkysWorkshop

14 күн бұрын

I'm not sure I agree about the backlash. Pretty much all lathes have a few thousands even with an anti backlash nut. I totally agree on the gibs. I'd say they are tight, the compound has some resistance to it but the cross slide might have some clearance. I now have a new belt on it and modified the motor bracket for higher tension. This has been on my to do list for a long time. I think the level of oil and debris on the belt reached a critical level. I suspect it will be MUCH better. When I restored the lathe I had to build the drive. I made it so that the weight of the motor provided tension for the v-belt and the flat belt but I also made 5 mounting points for the motor. By moving the motor down closer to the floor the tension arm is longer and the motor weight has more mechanical advantage. Not having a longer v-belt on hand was a deterrent for making the adjustment. I now have way more tension on the flat belt. I suspect it will be a new lathe

The chuck you have may have been sold to you as being suitable for use with wood, but it isn't. A better and safer project would be to make jaws that have a larger area of contact with the wood because wood is very inconsistent in its compression rate depending if the force is a Ross the grain, parallel to it . Most chucks made for woodturning can be fitted with a range of top jaws to accommodate a range of sizes. That is what I was saying could be a better project. On another topic, I need to visit with you about a new flat belt for my Southbend lathe. John

Honestly I understand there are better chucks for wood but this metal lathe chuck is much better than the one I had on the wood lathe. It was terrible. Also before I sold my Logan I used my 3 and 4 jaw all the time on my CNC with very good success. I turn brass, aluminum and wood on the lathe and the wood is mostly square so a self centering 4-jaw is ideal. Also the forces on a CNC wood lathe (at least my CNC) are much less extreme than a standard wood lathe. The cutter is most often 1/8". If i was turning bowls I'd be concerned. As for the belt, send me an email at Winkysworkshop@GMX.com

I have the same problem with my lathe , slowing down or stopping can't seem to get the belts tight enough ( to many belts to begin with) thinking about going direct drive with a VFD what do you think. THANKS WINKY ENJOY YOUR VIDEOS.

@WinkysWorkshop

15 күн бұрын

VFDs are great but they have there own issues. Mostly a loss of torque at low speeds. Truly direct drive would be difficult (too slow for most motors). With that being said, a lower RPM motor is a plus. That way you are closer to the rated RPM when you run slow. Something i learned about motors and VFDs is that you can also run the motors much faster than rated. Apparently you loose torque at higher speeds as will but usually you don't need the torque at higher speeds. I have a 1120 RPM motor on my mill and it allowed me to gear so that I never have to move belts. I'm running the motor up to 2200 rpm. I still lose a little with very low speeds but not much.

The lathe sounds better
