Turning a Morse taper 4 from a scrapped lathe part using my vintage lathe

[@RepLicanT00100]

And that is it. Could buy , or just build…to learn new things ! 👌🏼

[@petertyrrell6690]

When fitting a taper, I use a small smooth flat file as it gives me the control needed to only remove high spots. Emery by itself isn't stiff enough and you end up removing low spots as well as high. If Emery is to be used, try supporting it with a flat file so that the Emery lies flat on the work. Thanks for sharing.

[@RepLicanT00100]

Hahaha , goddam I appreciate your brutal monotone honesty. 👌🏼🤣

[@michaelhorn9267]

just one little tip - it's best practise and old school to first machine plane faces and then centre drill. With this you'll have your centre drill not moving anywhere and avoid the step of grinding the plane face.

[@Rolingmetal]

Usually I do that. But this piece was sticking out to much to face off an interrupted saw cut.

[@cannonroberts5129]

Thank you for all the great videos.

[@lv_woodturner3899]

I have only made one Morse taper so far, an MT2. I appreciate the challenge of turning tapers. Every detail is important and can impact the fit. From the last test with commercial taper, it looks like the spindle taper is part of the problem. Bummer. The metal you used was likely hot rolled steel. You managed to get a decent finish, well done. Not easy with hot rolled. I look forward to the next video. Dave.

[@Rolingmetal]

I now suspect the rear of the internal taper might be the problem. It might have taken a hit when punching out a tapered tool. I guess we'll find out in the next video :)

[@zephyrold2478]

Your internal lathe taper cant be damaged by punching out the tapered tool, if so sell the lathe to someone you realy dont like quickly, have you tried to messure the factory drill chuck arbor to se if has the same runout and maby the highspot the same place according to your "mark" on chuck back plate as the one that you made, if that is the case then you have found the cause of your runout.

[@albertmagician8613]

@rolingmetal or it was poor quality to begin with. I would use an abrasive paste and hold the taper in the lathe at low speed. If the overall shape is reasonable this results in an excellent fit, but maybe also in less runout. You have nothing to loose.

[@christopherbarnes6976]

Thank you for showing checking the runout. Abomb79 makes it look so easy, but it isn't for us mere mortals. You did a great job. Thanks for the video.

[@johnstrange6799]

Good to see a new one from you. Always enjoyable.

[@Rolingmetal]

Next one won't take so long :)

START 8 bit NES game 7:17, cool. By the way, i love nes. jaja. Beyond that, keep doing videos my friend. You re funny and show what you have to do and what not. And not everybody show their mistakes, it needs courage. Greetings from Argentina.

[@vijaypanchal7593]

Hahaha Blue contact most perfect method i was manfacture of bearing adapter sleeve i was matching 100 percent blue contact It was my passion

[@Rolingmetal]

Sure, if you like blue fingers :)

[@11Aldebaran11]

My friend I believe that your problem is on your lathe compound gibs. Try to take them out clean and polish them. Check also the compound dovetails. I see this kind of imperfections in many of your projects. Anyhow “Don’t Worry and Keep Turning”.

[@satxsatxsatx]

good work, learning much, looking forward to next video

[@GreatOldOne]

17:36. Acceptable to hear this in the workshop. God help you if you hear it in the bedroom... 😜

[@Rolingmetal]

lol. I case of complaints I can always turn a satisfactory dildo from some scrap metal. Might make an interesting video :)

[@GreatOldOne]

Rolingmetal only if it’s three phase powered. Then you can blame the squealing on the VFD when the neighbors complain. 🤣

[@DavoShed]

How did you set the angle? Did you offset the the tail stock or do you have some kind of taper turning attachment? If you off set the tail stock then your work piece would need to be the same length as your commercial arbour or you would get a different angle. I curious how you got this to work.

[@Rolingmetal]

see 11:06 I lined up the topslide with a store bought arbor. Can't offset the tail-stock as it's one piece.

[@DavoShed]

Ahh you used the compound slide. :) I doubt the tailstock would move that far even if it is adjustable. It's hard to get a good finish when you are winding the slide by hand. To get a nice finish we used to slow the RPM right down use an oil stone on the cutting edge and flood the tool with coolant. If the boss caught us doing it we could get in trouble as it takes too long when you are paying by the hour. You need machine feed though, you would go crazy winding it by hand. If you have the time and can use power feed it comes out very nice. Thanks for sharing your video. I have often wondered how successful it would be to make a morse taper on a standard lathe.

[@MrMa1981]

Oh dont worry the dial is shock proof

[@multiHappyHacker]

been meaning to mail the package, the paperwork on the customs form set me back a day or two then I got busy :/

[@Rolingmetal]

No rush, I've got more then enough junk to play with :)

[@pgs8597]

Great video, what’s a couple of thou, just needs a bit more polishing and use the reference points you mentioned once you find the sweet spot. Cheers Peter

[@Rolingmetal]

I got an idea. I might fix the problem. I might not. We'll see in the next video.

[@ChirpysTinkerings]

I wonder if you have a chip in the spindle still or a burr from the reamer?

[@Rolingmetal]

it's not the scratch I made that feels a smooth as a baby bum. But the rear of the spindle taper might have taken a hit from punching out a tapered tool.

[@ChirpysTinkerings]

yea, maybe, but kinda hard to see that happening tho, expecially on the multiple tapers. Another thing that could have happened is that the metal had actually moved due to internal stresses relieving, since that was kinda some unknown cast steel.

[@cecil6711]

Great video. :-)

[@rickox12]

Waar voor gebruik je eigenlijk die meenemer?

[@albertmagician8613]

@Rick Een meenemer is nodig als het werkstuk tussen centers draait.

[@jacka.4774]

LOL, funny guy, comedian too ha.

[@someotherdude]

omg that intro was harsh! Apologize or I'll send this video to the guys over at the Practical Machinist forum. I enjoy your videos. Except when you commit Lathecide.

[@denniswilliams8747]

"Arkansaw!" is the way it is pronounced :

[@Rolingmetal]

Not as silly as the French. They more or less drop every second s.

[@rowandunn2403]

An intage lathe on rolingmetal could this day get any better way to go buddy

[@Rolingmetal]

Thanks for pointing out my spelling mistake :)

[@rowandunn2403]

No worries here to help

[@coldformer1]

good video ,no videos for a while i thought you joined a monestary

[@Rolingmetal]

No, had to reinstall my stupid computer. So I enjoyed the summer instead :)

[@jusb1066]

.04mm runout is only 1.5 thou, pretty much near the 1 thou accuracy your ever going to get

[@Rolingmetal]

I guess, but I hoped I would do better :(

[@vijaypanchal7593]

Rolingmetal blue contact should be 99 percent actually there should be .01mm max runout And after taking from spindle u should again fit it and check runout it should come same I like u use puppet dial to check runout its a right dial to check runout

[@vijaypanchal7593]

Jusb1066 still u use word thou in India they forget thou My father was telling in his time micrometer were in thou 1 thou is 0.021 microns

[@vijaypanchal7593]

Rolingmetal check your spindle runout

[@jusb1066]

@@vijaypanchal7593 yes we too in a country with metric have forgotten, but many older toolings and also what sticks in the mind is sometimes the older system, one still has to work with both systems sometimes

[@pummppkinn]

I hate it when you try to save a little money and make something yourself, but it ends up costing 10x more than buying the item because of how long it takes...

[@pgs8597]

Tyler Lipsky Time is not counted in home / hobby shop otherwise you’d just buy everything new and go play golf.

[@jusb1066]

yep rather spend all day making an abor than playing golf and bombing other countries

[@Rolingmetal]

If I just bought an arbor than there would be noting to hate, and you would have to watch real live television instead.

[@pgs8597]

Rolingmetal , but this is reality TV

[@larryrose7367]

I thought most Chinese lathes were mt3 taper head stock

[@Rolingmetal]

I think you can buy them in all sizes. But this one is a bit odd because it has a MT4 headstock and a MT2 tailstock. I would have preferred a MT3 tailstock.

[@danielvandertorre7505]

I think the problem maybe the old lathe time to get the gun out

[@garthodonnell3661]

I feel you on the frustration but seriously, I see u cutting corners all the time, u even mention it as your doing the wrong thing.... You have run out on a part u machined directly in the spindle, first thing you'd do is check the spindle runout? The indicator was right there but you didn't bother...? Also if the high spot is only in one spot on the arbor after rotating in the spindle, then it has to be on the arbor, otherwise the spindle would have transferred the mark around the arbors circumference.. And then you find yourself disappointed about the lack of precision in ur parts when your working on a crackerjack chineseium lathe with little respect for the rules.... Yet I cannot stop watching? I do love the "realness" of your 10 degree barn with those AB htz screamers and I'd be lying if I said I've learnt nothing from your videos.. Keep em coming and maybe be a bit more patient. Haha ;7o

[@rotattor]

Just be careful what you polish you might go blind

[@Rolingmetal]

Yes, that what I heard. Nasty business, polishing!
