A Simple Screw Cutting Setup And Some Good Old Machinists Threading Tips.

[@pyromedichd1]

As a self taught home shop machinist (and I use the term machinist lightly because I don't call myself a carpenter because I can drive a nail), I really appreciate the tips and tricks of someone who has been in the trade for years and really knows the ropes. Thanks for the great videos.

[@daveticehurst4191]

Thanks for your view and comment, glad you are finding them useful. Wracking the Brain at present to come up with more tips and tricks. Stay tuned. Regards.

Absolutely use spring passes. On lathes and when milling too. Most all parts and cutters deflect. Thanks for the video!

Hi Ray, Thanks for the view and your comment. Glad you agree about spring cuts. Most people do not bother on KZbin. Regards.

Hi Dave I watched the video a few times to understand just what you were doing. I get it now thanks for explaining it will give it a go next time I do some threading. Thanks Cheers

[@daveticehurst4191]

Hi Randy. Glad it helped, drop me an email if you would like any further help, send me a note too of how it comes out. I use carbide thread inserts and do a direct plunge with the cross slide. Can see no advantage with the compound method for small threads less than 1 inch diameter and fine pitch. Only do compound for say a chuck backplate 1.5 inch and say 6 tpi. Thanks for watching. Been asked by a new subscriber to show how threading works on a Hardinge. Quite different to a standard lathe. Stay tuned for it in a short while. Waiting on a new camera with a zoom lens. Regards.

[@MrFactotum]

as usual Dave another great tip, Only trouble is, many or most Myfords don't have re-settable dials, been meaning to modify mine for the past 30 years or more, but i'm either bone idle🤣🤣🤣 or there is always something else to do!!! but i will get around to it one day, instead of using a Sharpie. Good to hear your subs are going up. take care Kev

[@daveticehurst4191]

Hi Kev. Myford do re settable dials both Metric and Imperial. Literally 5 minutes to swap but cost 50 GBP each.😢😢😢 Thanks for watching. Regards

Hi, I use the other method for screwing and that is with the compound set parallel to the work as in normal turning. To keep the right side of the tool from chewing the flank up as you dig deeper.....you only want to cut on the left side of the tool........ I advance the compound a few thou to the left at each pass......been doing it that way for the last 60 years or so......the tool has a top rake slanting from left to right as it only cuts on one side so a top rake cuts very clean. I also have a set of brazed carbide tools I specially made for finishing the thread to form the final pass and they are flat top form tools in 55, 60 and left and right hand etc. What's the advantage?..........well you get the exact depth of cut on the crosslide dial, but with any method if you first cut a small step at the beginning of the job or undercut the end of the thread length to the depth of the thread you have a depth indication.......but mostly you cut threads until it gets a bit pointy and then touch the top with a fine file to round off the burrs......a lot depends on the radius you have on the tool point for final depth, so its cut and feel at the end of the threading etc. I notice a lot of people have removed the compound slide in preference to a solid block mainly due to the pathetic mounting of the said slide on some of the cheaper lathes and it's ability to move or tilt when parting etc......not my cup of tea.........however, screwcutting with carbide inserts means you go fast and deep with each cut and that is on both sides of the tool. The QCTP, although a gift from Heaven, does add a huge lot of overhang when parting and that's where a rear tool post on the end of the crosslide with the tool upside down comes into it's own..........that was a godsend for lathes with plain bronze bearings that had a tendency for the spindle to lift (oil clearance) when parting from the front, but with the back tool post, the tool being upside down and the spindle running normal direction, the work is pushed down in the bearing and so no drama or soiled underwear from parting tool crashes.

[@daveticehurst4191]

Hello Ian. Thanks for watching and this excellent comment. I do not use compound for screw cutting either. I am a plunge person but use carbide inserts. I also use at times the inserts that finish the final size, turn shaft 0.004" oversize. Keep advancing the insert until correct diameter is reached. No burrs, smooth as a baby's bottom. Unfortunately you need to buy one for each PITCH of thread you want. Can be used on any diameter, so if you want a special diameter but standard pitch you can use them. Great story behind your many Years of machining experience, thanks for posting it. Regards.

Great tips Dave, I was taught very similar way back when. Lol, "not another screw cutting video"........ along with the obligatory ball turner, a screw cutting video seems to be a right of passage for KZbin machinists! I used to also use a fast threading device back in the late 80's, it had spring passes pre-configured into the units mechanism. Cheers, Jon

Thanks Jon. People seem to be liking this type of video, getting lots of views and new subscribers, so I must be doing something right for once. Regards.

[@russelldold4827]

Thanks, Dave. Valid tips. If you set the compound slide over by about 1/2° less than half the thread angle you may find that the rear tool flank shaves the ridges on the rear face of the thread as you progress deeper. If your HLV has the automatic screwcutting feature, perhaps you might consider making a detailed video on setting it up and cutting a short thread. I have seen other videos of them in action, but none show how to set it up.

[@daveticehurst4191]

Hi Russell, thanks for the view and your comment / question. I do not do single point screw cutting on the HLV using the compound. I use carbide inserts, either the standard 55 or 60 degree, with the occasional dedicated insert which gives a perfect thread profile. For those I use the cross slide only and do full engagement threading. To be honest, theses days if you have a professional machine then plunge cutting is fine for most common threads say up to m10, m12 etc. Taking care not to make too big a cut each time. You really only need the compound job for coarse and deep threads like lathe chuck backplates. Yes I suppose I could do one in the near future. I am waiting on a new 4 K camera that has a 16 X zoom and a 3 inch screen. See you again soon. Regards.

[@russelldold4827]

@@daveticehurst4191 Carbide inserts make perfect sense and give perfect results if the budget allows. I'll be using high speed steel 😉

[@daveticehurst4191]

@@russelldold4827 OK, duly noted. When I make the video I will show HSS threading as well as using inserts. Watch this space. Regards.

compound is set at 60 degrees

[@daveticehurst4191]

I know, it was only set aproxomately as an illustration on setting the correct thread depth easily without calculus or using a DTI. Thanks for watching. Regards.

[@deedeeindustrialsuperprecision]

Good video, sometimes the material will not respond to spring cuts well. I have some pre-hard alloy steel that will work harden with anything less than what would be a roughing cut but can still be threaded nicely if the machine is heavy.

[@daveticehurst4191]

Thanks for the info and your view. I mainly use non ferrous and occasional leaded mild steel so have no experience of your material threading conditions. Regards.

[@paradiseroad6405]

...compound needs to be 30 degrees from perpendicular with the spindle axis... ...yours looks to be 30 degrees from parallel with the spindle axis... ...only the former will work correctly... ...some compounds will read 60 degrees when set correctly...

[@daveticehurst4191]

Hello there, thanks for you view and your comment. In actual fact the compound was not set to anything in particular, it was just shown at an angle as an illustration. I mentioned that it needed to be set to 30 degrees. The purpose was just to show the dials setting trick. I do not use compound threading, most of my threads are small and fine pitch, I plunge cut using carbide threading inserts. Regards.

[@kevinbarrett3]

His compound is the wrong angle. It’s not for threading , that’s for sure.

[@daveticehurst4191]

Hi Kevin, YES I know, it was just set at any angle , I was NOT intending to cut a thread. The purpose of the demonstration was just to show the method of how to set the dials. I did say SET to 29.5 or 30 degrees. Thanks for the view and comment. Regards
