The engineering that went into those machines is mindblowing, especially when you consider it was likely done with paper, pencil, a slide ruler, and a protractor. What I find really amazing is how quiet the movement of all those big, heavy metal parts are.
You do know that this video (first watched back in late 2017), drove & hounded me to one day move up from my SB 9c to a larger lathe with a tapper attachment,,,,That day came on February 6th 2021 when I found a 1941 LeBlond 17 here in TX,. Not only with a tapper attachment, but a load of tooling (@@)! Now setting in our mom & pop Hot Rod Shop, with a Big Smile on my Face
I asked a question about taper turning. You recommended looking back over your older videos, so I did, I found it, and you've explained it perfectly. Thanks again Adam.
Please do not apologize for any thing!! Some folks need to try and validate themselves by nit picken. You make a living with what you do. We appreciate your time and knowledge. You are a superb machinist and teacher.
Yeah, especially compared to the twig and a two by four you built for your Clausing! Hee hee, jk man...though there is a difference in design, you made yours work wonderfully. Game show, game show, game show...ding, ding, ding, ding! :D
Hee hee, I was in such a punky mood, and now I'm feeling a mixture of embarrassment and fear. Hopefully Old Tony won't take me out "fishing" and have me whacked, like his name would lead one to believe :D
Ha! Something about that made me think of Dirty Ol ... er, Grumpy Old Men II, the old gal brandishing a ladel or cast iron pan, saying "Now can I whack him???" I wouldn't worry too much about it, unless a little ninja suddenly appears with hand on shord hilt...
Thanks for the explanation. I have a Monarch CK12. I finally found the clamp for the taper attachment to the bed. Only took 14 years. Seems like people take those off and loose them pretty regularly. I can not for the life of me figure that out. Anyway, look forward to doing some tapered parts now. So, perfect timing on these three videos. Thanks so much.
Excellent explanation on the taper attachment. I was keeping an eye out for one to put on my DSG but now realise the whole cross feed arrangements would need to be changed as well. Possibly saved me some money 👍 not that I’ve ever seen one for sale. Thanks Adam.
My Springfield 280 came with a taper attachment but I've never tried to use it. I wasn't even sure if I had all the parts. After watching this video and understanding how it is supposed to work, I went and set it up and found out I do have it all and it works. Thanks Adam.
Hi Adam, I cut my teeth in 1956 on a big 1936 Monarch with a taper attachment just like yours. I used the attachment many times but never understood how it could move so freely while the lead screw remained stationary. Now I know the screw has to slide in a coupling somehow to allow both to be used. Thanks a ton, my 60 year old puzzle has been solved.
I greatly appreciate this video. I have a 1905 lathe with a taper attachment that is missing a couple pieces. I'm fully restoring it and this video was just what I needed.
thanks man! you saved me. i wasn't familiar with the taper guide and wasn't sure why it wouldn't cut the angle i set. after seeing how it's supposed to move from your video; i realized it just really needed to be taken apart and lubed up. and a couple screws on the compound needed backed off slightly.
Having a background more in mechanics that machining, I fully understand and appreciate the Monarch more than ever. The genius of the designers of those machines was incredible.
They really did put alot into that machine, the design and engineering involved. They wanted there lathes to be the best in the world and last a lifetime.
Thanks for the inside look Adam, it was quite clear how that was possible. It's just 16 times more complicated than I could have imagined - simple, right? Obviously the guys that designed that system knew what they wanted out of a lathe long before this one was a new model, so that goes back a ways and then some. The heritage runs deep and strong in that one.
Thanks for the video Adam! I've got a Clausing Colchester very similar to John Saunders and have never messed with the taper attachment because I thought I had to disconnect the cross slide like you mentioned. Watched your video, went out to the shop, and was set up to cut threads in no time.
Very good video and example of machine design. I did not look forward to single point threading on the lathe until I got to work on an HLV-H which had a bit different mechanism for pulling back, but like the Monarch and other higher quality lathes made the threading process much easier. I appreciate that you get to the point where critical comments are too much. You are very careful about going over the possible consequences of techniques that you use. There are thousands of choices that must be made by a machinist and just as many factors that go along with deciding how to accomplish a task safely and efficiently. I think your judgement is excellent and while I respect the concern and opinions of others at some point there needs to be an acceptance that we are not all going to see or do things the same way.. Thanks Adam.
Adam, it doesn't matter what people say about your tools. If the tool works for you then, it's perfect. The important thing is to get the job done safely and quickly. I have many tools I have made and they work for me. That's why I always say on my channel "Work smarter, not harder."
Great video. Keith Rucker has a series of videos where he restored a LeBlond lathe. He shows how the taper attachment is assembled, so it makes it really easy to understand. It isn't exactly the same because they are different machines, but the basics are similar.
Those were some Smart People that Designed Machines back then. A Pencil, Some Paper, A Drafting Table, A Slide Rule, and Their Brain. No Calculator. No Computer. No CAD. No CNC. Wow, Just Amazing!
I work in a manual machine shop with alot of old worn machines missing parts to the taper attachment, and always wondered how they worked. My dads a master and explained them, but to actually see them set up and moving makes all the difference. Shame we dont have them working, im on a job this would do wonders on speed and accuracy. Thats for the informative video!
This video is very cool and useful work Thank you Professor Adam The most beautiful thing in this video is two movements at once Yes, a lot of this video may take advantage despite the surprising at first until completed explanation. Great work really
Hi Adam I have seen you use that polisher a number of times. Every time I saw it in use I thought" wow, that makes loads of sense and does a great job ". regards vic
I've seen some of those comments in the past about you sanding and polishing. When the safety Nazi's come out, they get vicious. I have no idea how I survived as a kid with no covers on the electrical plugs and riding standing up next to my dad in the car. I see you have all your fingers so you must know what you're doing. May God be with your brother and I pray everything works out ok. My 15 year old grandson has Crones and it makes life challenging with the IV's and such. Thanks again for what you do for our entertainment.
Thanks Adam! Made sense once i saw that leadscrew move ;) so much quality in those machine so well thought out and designed. Again thanks for taking your time to explain - its why your a pro Cheers Troy
So THAT's how that works on the taper attachment, and how you can still use the crossfeed while tapering! That's an awesome piece of ingenuity and genius mechanical engineering! Cross-feed screw is anchored to the moveable bar that the taper-attachment is in control of, with as you stated, a male-female sliding shaft connection, either keyed, or more likely splined, between cross-feed screw and cross-feed handle and dial. As well built as the rest of the machine is, I'd be surprised if the sliding-shaft setup between cross-feed handle/dial and cross-feed screw isn't splined. Besides of course how this arrangement permits you to still adjust cross-slide position no matter where you are in the taper-attachment's travel, I can also see a major safety benefit as well: when turning a taper using the tapering-attachment, the cross-feed handle isn't turning. If it were turning on its own while using the tapering attachment, I'm guessing that can lead to operator confusion at times possibly and a machine crash if you accidentally engage the power cross-feed when you meant to disengage it. With the cross-feed handle not turning when using the tapering attachment, you know at a glance that the power cross-feed is off. As somebody else has said previously however on this, it would make sense if in the process of setting up the taper attachment for use, one of the setup steps by design also serves as a 'safety feature' to lock-out the power cross-feed, so the power feed for the cross-slide is disabled and cannot be engaged while the taper attachment is setup and ready to use.
thanks for the explanation of the belt sander/polisher. I also like the taper attachment on that monarch. we've got one on our southbend. it functions fairly well but nothing to brag about.
Nice writeup......I haven't run a taper attachment in over 30 years..........so it seems to have helped......that polishing tool is boss.......never seen one like it
Guess I wasn't the only one wondering how the lead screw interacted with the taper attachment, now it makes perfect sense. As always, thanks for the great explanation Adam :)
Good video. The lead screw has a keyway in the handle end which fits into a collar attached to the handle. that allows the entire screw to move under taper turning, while still allowing you to adjust the depth of cut . That big worn out nut on the end locks the slide into place when doing normal turning so the screw cannot accidentally move. Keith Rucker just did a video on assembling the cross slide and taper attachment on his Monarch for those who want to see how it all goes together.
Thank you for taking the time to explain that taper attachment Adam, it has always puzzled me how it works, my little lathe does not have that ability. BTW we all do polishing of some sort on the lathe. A quick clean up before moving on is all it takes. The type that bitch about it probably never done any machining EVER!
The monarch taper attachment works similar to the one I have on my old Pratt and Whitney model B. on mine there is a dog screw to lock the separate taper slide in the carriage. the thing I like about my taper setup over other brands is that the taper attachment hangs on its own independent machined surface on the back of the bed versus being attached to the rear top ways of the bed and doesn't ride along with the carriage when not in use.
Taper attachment part begins at 9:21 And thanks for the explanation. Eliminates my thought of adding a taper attachment to a lathe that wasn't built for it.
Great share. At the beginning I thought that was an arc'ed path the taper attachment was set up for, because of the lens distortion - I thought "How neat, you can probably cut any path/shape, then." I guess that would be pretty complex to create anything but a straight taper.
Once again, and as usual a splendid tutorial.....but if I may suggest, when you have nothing better to do, a tear down and repair/update of your Monarch lathe would make for fascinating videos and I am certain that you would get many thumbs up.
Basically it is specifically designed and made for this lathe. This is not something anyone can just put together and put onto a lathe! Thanks for taking the time to show this! Edit: Looks like the 25 thou slop is in where the screw connects to the taper attachment
Good little Video on the Taper attachment. I had to make a couple things for my Le Blond and then haven't had to use it. If I hadn't of made the parts I would have needed them.
Nice. That Monarch is a beauty. Anyone that criticizes you using the crankshaft polisher can go take a dive into molten steel. Every serious race engine shop, let alone OEM remanufacturer has one and uses them in production as well as custom engine machining. I've used them hundreds of times. A must have tool in any serious machine shop. End of rant...
Your molten steel comment took me back to Terminator 2 and the ending with the T-1000 shrieking like a stuck pig, LOL! "Come with me if you want to live"....dang, I can't believe that was 25 years ago already!
Doug Hanchard oh hi California. I hate ANY negative comments toward Adam, especially about such a unique and marvelous machine. Thanks, Adam, now maybe I can figure out my south bend taper attachment! Cschwad.
I really don't get why they get so anal about it. I mean, all it takes to protect the lathe is some wrapping paper, and you're done. I have a similar belt grinder, tho mine (through a mod) attaches to the tool post so i can power feed the grinder. Man that thing makes some sick polishing marks. :)
I'm just jealous I don't have a legit crank polisher. If you haven't polished parts then you have never needed a perfect air tight slip fit that snaps when you pull it apart. I don't own a cylindrical grinder so it has to get done some how. That aside maybe the millenials don't know how to clean up after their grinding dust. I mean they expect everything else handed to em.
Best turner I've ever seen and taught me a lot of interesting things. I would recommend the szczegulną carefully watch his movies :-) Pozdrawiam z Polski
thanks for all the great videos. I'm 24 from tulsa ok and i machine my ass off everyday the good old way. I realy don't know many people my age that use manual machines. everyone my age wants it to be computer drivin and pre written, but when faced with a one off problem they can't over come it. I started uploading some of my machine vids as well and hope to add many later thanks to your encouragement.
If it's like the Colchester chipmaster, the cross slide screw is splined at the Handel end, and the other end is bolted into the taper attachment slide. This means that the screw moves as it slides down the taper attachment, taking the cross slide with it.
Thanks for the detailed look, Adam. I was wondering how Monarch managed the other degree of freedom on that cross slide. My little Logan lathe (which my wife blames you for) had a taper attachment most of which went missing before it came to me. It was a MUCH more limited arrangement that these machines that you grew up with.
MattsMotorz Iḿ feeling same away about polishing on the lathe.. Throw couple old t-shirt to cover the ways and thatś that... If the camshaf from engine hav to machine out to next over size bearings. First off itś grinded and after that itś polished to size hand held emrypaper or by machine like yours adam.... It has also WAYS in it! Lathes are made to working NOT TO BABY OUT THEM!!!!!!! Ofcourse you hav to take care of them best way you can :-)
If my memory is correct, MONARCH patented their taper-turning attachment. It's generally referred to as a telescopic taper-turning attachment in order to distinguish it from the plain type.
Shop project alert! - make a new doohickey for your taper attachment to replace the worn out one. :) You could also put a small, rectangular magnet to replace the missing clasp (?) on the guard so it doesn't slide around like you demonstrated - just attach the magnet to the ways where the clasp was, rest the guard piece on top, and adjust the location of the magnet so the guard piece rests on it. Now affix one side with 2-part epoxy and let it set up! Keep up the good work!
Thanks a bunch Abom, I was trying to figure out how to use the one on my monarch and for the life of me couldn't see how it was supposed to work. It's because I'm missing that locking bar. The bar was broken off but I have it, the locking piece is completely gone though so I guess I'll have to fabricate something.
thank you, adam, for the explanation! it would be nice to see any repair on that screw and nuts if you ever decide to show it to us. thanks for the video, -toly
Hi Adam Another very nice video. I wondered if you had just installed the taper attachment for the last video, but there were just the covers in place. Anyway it was a very informative video, the way this taper attachment works is quite impressive and very well engineered. I personally find it really impressive how well those "older" machines were designed, just with pencil and paper and no computer and CAD program. BTW, is the belt sander self made or an off the shelf tool?
The engineering that went into those machines is mindblowing, especially when you consider it was likely done with paper, pencil, a slide ruler, and a protractor. What I find really amazing is how quiet the movement of all those big, heavy metal parts are.

It’s the kind you’d need to fix this old Tony’s tapers

That last video on turning a taper was awesome! A highly challenging and difficult machining task executed with the precision of a Ninja!
I'm not sure how I missed this video when it came out but thanks for making and sharing, good information.
Thanks Adam. That's very cool taper attachment. I like the belt sander too, I see you always carefully cover you ways. Thanks for sharing

Great video Adam. Thanks for clearing up those points. A Happy New Year to you and yours. Thanks for sharing. regards from the UK
I had always heard that Monarch was the Cadillac of lathes. This just reinforces it. Great ingenious designs on the mechanisms!
Now it makes sense. What a clever design! Thank you for taking the time to explain the mechanism.
Thanks for all the time you put into these videos. You are a scholar and a gentleman!!
Thanks for the inside look Adam, it was quite clear how that was possible. It's just 16 times more complicated than I could have imagined - simple, right?

The most beautiful thing in this video is two movements at once
Yes, a lot of this video may take advantage despite the surprising at first until completed explanation.

Super awesome journal polisher! I use them a lot when cleaning up a crank. Super easy and simple
Thank you. Picked up a lathe with a taper attachment and haven't had time to mess with it and haven't had time to mess with it.
Thanks...Reminded me of my Dad when he worked as a toolmaker in South London.
Just take a look at Keith Rucker´s current LeBlond restauration, there´s a nice video of assembling a similar taper attachment

I just got a southbend 9a with a taper attachment and this really helps me alot. Thanks.
Aha! Thanks for turning on my light and you have a very "teachable" way of explaining everything you do. Congrats on almost 110k subscriptions.
I'm studying for 1st year apprenticeship and I believe the taper attachment is called a Plain Taper Attachment.
Thanks for demo.
Thank you man, that was a great video! Now I'm totally understand how taper attachment works. Greetings from Hungary!
Thank you for taking the time to explain that taper attachment Adam, it has always puzzled me how it works, my little lathe does not have that ability. BTW we all do polishing of some sort on the lathe. A quick clean up before moving on is all it takes. The type that bitch about it probably never done any machining EVER!

Great explanation there Adam. I had wondered about how that worked and it was buggin me a bit. I can sleep easy now!!
Great stuff, Adam. Very enlightening. One mystery explained!
Cleared up a lot of questions for me. Thanks a ton!
Good explanation, and I like the thumbnail, Adam!
Thanks! I thought it made for a funny thumbnail!
Thank you Sir. I sure needed that. Please don’t think any detail is too small to mention.
Amazing. Beautiful work. First time I seen how a taper was machined.
Always interesting to watch your videos. Keep it up!
I enjoy watching your videos I am starting to get into lathe and mill work
Careful, you'll be hooked on Iron for life... ;)

You have a way of teaching with out over thinking it thanks for sharing.
the keyway was visible in the close up shot where the female collar attaces, that's one hell of a slick setup.
Nice. That Monarch is a beauty.
Anyone that criticizes you using the crankshaft polisher can go take a dive into molten steel.
Every serious race engine shop, let alone OEM remanufacturer has one and uses them in production as well as custom engine machining.
I've used them hundreds of times. A must have tool in any serious machine shop.

Your molten steel comment took me back to Terminator 2 and the ending with the T-1000 shrieking like a stuck pig, LOL! "Come with me if you want to live"....dang, I can't believe that was 25 years ago already!

Good video Adam, looking forward to the next one.
Thanks for the video, it helped explain a lot about what is going on.
Have a day
That belt sander is definitely a crankshaft linisher, the place I used to work at had those exact ones for their large crankshaft grinding machines.
oh man..that's clever!
Great explanation Adam ☺
Always an education. Thanks for the video Adam.
Great work again, Adam. Thanks!!
Best turner I've ever seen and taught me a lot of interesting things.
I would recommend the szczegulną carefully watch his movies :-)

thanks for all the great videos. I'm 24 from tulsa ok and i machine my ass off everyday the good old way. I realy don't know many people my age that use manual machines. everyone my age wants it to be computer drivin and pre written, but when faced with a one off problem they can't over come it. I started uploading some of my machine vids as well and hope to add many later thanks to your encouragement.
If it's like the Colchester chipmaster, the cross slide screw is splined at the Handel end, and the other end is bolted into the taper attachment slide. This means that the screw moves as it slides down the taper attachment, taking the cross slide with it.
Great video explaining how all that works. Cool stuff
Thanks for the detailed look, Adam. I was wondering how Monarch managed the other degree of freedom on that cross slide. My little Logan lathe (which my wife blames you for) had a taper attachment most of which went missing before it came to me. It was a MUCH more limited arrangement that these machines that you grew up with.
Just had an idea for the use of your new aluminum handle you showed us in the last video. Use it to lock/unlock the taper attachment.
Always enjoy your videos Adam....
Thanks for the video Adam! I was burning my brain trying to figure it out hahahahah. Thanks bud!!
I get it now! Thanks Adam! And screw those guys complaining about polishing on the lathe!
MattsMotorz Iḿ feeling same away about polishing on the lathe.. Throw couple old t-shirt to cover the ways and thatś that...
If the camshaf from engine hav to machine out to next over size bearings. First off itś grinded and after that itś polished to size hand held emrypaper or by machine like yours adam....
It has also WAYS in it!
Lathes are made to working NOT TO BABY OUT THEM!!!!!!! Ofcourse you hav to take care of them best way you can :-)
Yep, cover the ways, or once done with the polishing wipe them all down which is what I do everytime.
I worked at a machine shop that specialized in large crankshafts for pumps and we used a sander just like that for polishing
Well done Adam
If my memory is correct, MONARCH patented their taper-turning attachment. It's generally referred to as a telescopic taper-turning attachment in order to distinguish it from the plain type.
Cool video thanks for taking the time to make it
Shop project alert! - make a new doohickey for your taper attachment to replace the worn out one. :) You could also put a small, rectangular magnet to replace the missing clasp (?) on the guard so it doesn't slide around like you demonstrated - just attach the magnet to the ways where the clasp was, rest the guard piece on top, and adjust the location of the magnet so the guard piece rests on it. Now affix one side with 2-part epoxy and let it set up! Keep up the good work!
Ojai, CA... pronounced O-HI. Thanks for sharing the inner workings
Thanks a bunch Abom, I was trying to figure out how to use the one on my monarch and for the life of me couldn't see how it was supposed to work. It's because I'm missing that locking bar. The bar was broken off but I have it, the locking piece is completely gone though so I guess I'll have to fabricate something.
thank you, adam, for the explanation!
it would be nice to see any repair on that screw and nuts if you ever decide to show it to us.
thanks for the video,
-toly
Ditto
If I ever get into the machine I will do that. I'd like to maybe one day, scrape the cross slide and gib back flat.
exactly what I needed!
Ahhhh! Now I understand. Great Vid Abom, thanks!
Hi Adam
Another very nice video. I wondered if you had just installed the taper attachment for the last video, but there were just the covers in place. Anyway it was a very informative video, the way this taper attachment works is quite impressive and very well engineered. I personally find it really impressive how well those "older" machines were designed, just with pencil and paper and no computer and CAD program.
BTW, is the belt sander self made or an off the shelf tool?
Very good explanation, Thanks
Ahhh, that makes sense! Good explanation Mate!
Very clear now, thank you
