The handwheel on the Mini Lathes carriage annoyed me quite some time. It wasn't properly supported by bearings and got sticky over time. Besides it was very wobbly, a bit too small and the handle unscrewed it self when turning the handwheel.
The plan came up to replace the handwheel, install some proper bearings and additionally add a dial to the handwheel. I missed a way of indicating the travel of the bedslide quite often in the past that I necessarily wanted to include a big dial to the modification. Off course you can install a digital readout which will be much more accurate but I wanted to go the old scool way here.
A problem was to figure out the travel of the bedslide per turn of the handwheel. This is important for making the dial. In it's factory configuration the bedslide travelled about 19,2mm per revolution of the carriage handwheel. That is quite an odd number and useless for an easy to read dial. With a little bit of math I found out that by changing one gear in the Mini Lathes bedslide apron from 24 to 25 teeth I'll get a travel of almost exactly 20mm. That's just perfect for a 200 dividion scale I then machined. The scale indicates the travel with a resolution between the lines of 0,1mm.
The result is quite satisfying. Not just that it looks great in my eyes and much more "real precision lathe like", it also feels so much better than the old plastic handwheel. Due to the two installed bearings it feels now extremely solid and turns smooth. The slightly larger aluminium handwheel and handle feel very comfortable.
As you see in the end the handle of the cross slide now collides with the new bedslide handwheel. That is to fix next :)

Amazing how much you can do with a small lathe. It just shows technique and knowledge is more important than having a big fancy expensive machine. I learned a lot from this video.
Same here. Nearly everything he showed was a lesson for me.
Even on a monster lathe most jobs are smaller. I have a 10x22” lathe for the garage at home and the big lathe is at work. If I get a bigger job on occasion, I just take it in to work and use the big lathe but my little lathe is my “go to” for most jobs.😀👍Keep making chips!🤣
And all without a mill! The lathe is the machine that can make itself,,,,with a little help from the drill press. ,,, but what impressed the most was your toolmaker grade workmanship and mostly the engineering. Second to none!
I know I am a little late to the party, but that dial is one of the most beautiful things I have seen someone make. I did a tiny little wheel for my compound. I had never thought to make one for the carriage. That was really wonderful. Now, I have to make one. I will inscribe WCDTB on the back in your honor. Thanks for that... a lot.
An extremely good result! Well thought out and some very creative set ups, and beautifully executed. Well done sir!
Thank you very much for your kind comment! I really do appreciate that! Happy to hear, you liked it.
Well...... THAT IS GENIUS lol! The piece of wood to lock the spindle. DUH! Thanks for this
I love how this beautifully executed modification concluded with a new problem to solve. I look forward to the next video!
Thanks for your commen! I would prefer, the problems will come to an end some day :D But there is still a lot to do on this little lathe :) And yes, the crossslide handle and scale is the next project
Lp
Now I understand why all of a sudden the launch date is delayed. 😀

@@Dodi-nz3fd dude, stop it! Every video where emco unimat 3 is you always ask same or similar question.
This channel definitely has the right name. You have a new suscriber!
Thank you so much for the kind words! I really do appreciate your support!
Now this is one of the best and best looking mini lathe upgrades I have seen done. Great idea and execution Beautiful finished product. Even the cross slide clearance issue I would normally call a mistake I said Ok … Good another project.
Truly amazing job. I especially like the smart locking mechanism with the two pins.
That’s next level workmanship wow just beautiful. You must have a great sense of pride every time you finish a project.
That was Awesome mate ,That was good thinking in the way you did the work , I'm a 70 year old Fitter & Turner
Thank you so much for your kind comment! I'm hubled! Thanks a lot.
Paper plate and dial indicator with and a wood shim as a diving plate. 🤯I have been humbled.
I saw your comment about the paper plate before I got to that part in the video and was puzzled by what you meant. Now that I've seen it, I'm humbled too. Impressive!
Well, I am impressed. The locking feature is very clean. I also like the indexing arrangement. Very cool enhancement.
Both the idea and the execution are absolutely stunning. Bravo! 👍 🇬🇧
Thank you so much for your kind comment!
@@WeCanDoThatBetter , Where can I buy this lathe, in *Indonesia???* .
Impressive. That was watching a work of love. Really I could feel how much you loved what you did.
great design, love it. I have added a thin backplate to the apron of my mini lathe to keep swarf out and to hold a bearing for the handwheel. I am using a handwheel on the lead screw and am planning to add a digital scale with the read head under the apron.
Amazing patience engraving the wheel. Excellent planning and execution was a pleasure to watch.
Thank you for your feedback!
Such a fine job! Great craftmanship through the whole video!
Alors là ! Bravo !!!! Félicitations pour cette modification !!! Then ! Well done !!!! Congratulations on this change !!!
Awesome work. Again. Thanks for sharing and taking the time to publish your work.
Wow what an amazing job 👍🏼 Some pretty clever techniques in there to accomplish this as well.
You do optimal work with less than optimal tools. The quality of your finished product is inspiring. Nice camera work too! Please keep the videos coming.
Thank you very much! I really do appreciate that. It may take a lot more time and needs some patience but even with little tooling you can achieve quite a bit :)

Subbed and binge-watched the whole mini lathe playlist. Keep up the great work and would love to see more mini lathe stuff!
Thank you very much for your kind comment! I really do appreciate that. There is more to come on that subject.
I love the “drills eye view” too cool. Fantastic Work
Wonderfully thought out ( apart from the colliding handles !! ) Very well made and fitted all in all a very entertaining and instructive video Thank you for sharing looking forward to the handle problem being solved.
Thank you very much for your kind comment!
@@WeCanDoThatBetter , Where can I buy this lathe, in *Indonesia ???*
Nice work. Great idea. I like the lock mechanism. Great and useful content. Thank you, EM.
Really nice design work and execution on this project. I have never considered using a graduated dial on a carriage handwheel before, but it's an excellent idea.
Have you never seen a lathe or any type of machinery before? Every single machine ever made has graduated dials on it. lol wtf
@@mapsi03 Yes, I've seen many lathes before (have you?) The crossfeed and compound handles are normally graduated, but I've never seen a graduated dial on a carriage handwheel - you'll note that the original plastic wheel did NOT have graduations. This is typical on all lathes that I'm aware of.
Thank you very much! That's right, not every lathe has a dial on the carriage handwheel. But that's a useful modification. Without a digital readout you have no idea how far you go with the carriage without a dial. I missed that extremely in the past. I oriented my design a bit on the schaublin lathes. They have beatiful dials on the carriage handwheel :)
@@WeCanDoThatBetter , Where can I buy this lathe, in *Indonesia ???* .
Nicely done, it's been quite an achivement was promising from the very beginning, congratulations.
Mate. Maaaaate. Well done. IMHO the dial clamp is the best bit of the assembly, exceptional function with simple design.
:) Thanks a lot! The clamping is really cool yes. Much more convenient as clamping with a screw from the side. I saw this idea in a video of Stefan Gotteswinter here on youtube.
@@WeCanDoThatBetter - very well done - care to share the video link from Stefan ?
Loving the angled pins, a very clever idea
Super rozwiązanie , dobry pomysł. Gratuluję. 👍👍👍
Your a very resourceful maker. Keep up the great videos 👍
Fantastic execution of the works. Thanks for share.
Thank you very much!
We probably won't do better than this😁 I really enjoy your videos for the great level of problem solving using a great deal of ingenuity with only limited equipment. The camera work is tremendous too. That is a sweet dial locking mechanism.👌
Thank you so much for your kind comment!
... now, this is much, much better ... well done ...
Great video as always! Looking forward to next one.
Stunning execution. 👍👍😎👍👍 thanks for the tips and inspiration.
Nice workmanship and end result is beautiful. Thanks for sharing.

Awesome design and manufacturing. I love how the lock works.
Thank you very much! The lock is really cool, yes. It is not my idea, I just adapted it for my project. It works exceptionally well :)
Loving this video a lot. Amazing stuff that you are doing on this little lathe. Cheers.
Thanks my friend :)

Very nice job! Professional and we'll thinked. Very pleasant to see. Be proud 🇲🇫
Brains, patience and skill. Wins hands down every time. Calculating to fifteen decimal places might be overdoing it a bit but I like your style.
That's some really nice work! Looking forward to seeing how you resolve the interference with the cross slide handle. :-)
Agree. Nice job. The unforeseen often shows up.
A lot of skill involved here. And some great inspiration and food for thought. It might be more of a personal preference, but for me, fixed handles (to the wheels) would drive me crazy. 😄 Looking forward to the next video. 👍
Haha :) Thank you very much for your kind words! The handle is actually a result of lazyness at the end of the project :) I first wanted to install a turning handle but then went for the fixed one to get the project done. Perhaps I'll change it later but to be honest the fixed handle feels quite ok for me.
@@WeCanDoThatBetter At least you finish your projects when laziness hits. That’s a lot more than you can say about my pile of 90% completed stuff. 🙄🙈 Happy it works for you. 👍
@@andli461 Haha :D That's really hard sometimes to finish projects I know that! :) And as said, perhaps I'll change that in the future :)

Good job as always. We shared this video in our homemade tools forum this week :)
Thanks, happy to hear! :)
Extremely impressive workmanship and it looks beautiful too! Now I want to see your cure for that cross slide handle.....
Thanks for your nice words! Yes, that's the next project. But have to make a plan what's needed to do first :)
I used to have a small 200kg lathe, very quickly I outgrew it and made room for a 650kg lathe. Ultimately I am very happy I didn't spend too much time modifying my small lathe before moving on. But this is done very nicely, definitely took some time and patience. Especially the handwheel engraving, nicely done! Personally I would save the effort and upgrade to a large machine before doing such work, but I understand this is a hobby.
Beautiful. 👍
Großartige Arbeit!! Macht enorm Spaß zuzugucken und Anregungen mitzunehmen!!
Vielen Dank für dein freundliches Feedback! Das freut mich sehr! :)
This is what I call Art. Really nice job!
I'm humbled! Thanks :)
Wow, that's an awesome upgrade!
Thank you very much! Yes, it is such a pleasure now to operate the bedslide. No wobbly handwheel anymore :)
Ingenioso, excelente, te quedo precioso, te felicito.
Brilliant idea for the locking screw on the dial. Ingenious!
Thank you very much! I have seen this on other machines. It is extremely handy.
Oh, the beauty of hobby shopping! You do all perfect, measure it twice, test assemble them all together, then… it interferes with the cross slide!!! 😂😂😂😂😂😂 Excellent job on the dial and great ideas! I’m working in a micro lathe and wondering if I can do the same due to the even smaller dimensions. Thank you for sharing!
Nice work. I very much like the locking mechanism.
What a beautiful bit of work!
Thank you! I really do appreciate that.
A great idea executed brilliantly 👍🏿
Thank you very much. I haven't used it a lot yet but it is really a pleasure to use with the big dial :)
Very nice design! I especially like your wedge lock. A similar method is used for timing chain adjusters on some motorcycles. I'm in your same predicament regarding lack of spacing between carriage and cross feed handwheels and my solution might work for you: shift the apron forward of the saddle. I'm doing it with a pair of steel blocks. One will go behind the apron and under the saddle and the other will be in front of the saddle and on top of the apron. In regards to your fixed handle, that's going to grow old fast. I've made replacement handles for all my Chinese machinery because it one of the things that we are in direct contact with, and it effects our perception/feel of the machine. I used ground steel shoulder bolts with a pair of needle bearings and turned aluminum handles. The handles are hard anodized (type III) to resist both internal and external wear. Combined with stainless handwheels, it dramatically improves the feel of inexpensive machinery.

Thank you very much!
So impressed! New subscriber looking forward to more. Thank you!
Thank you very much for your comment and for subscribing! I really do appreciate that.
I am definitely 'late to the party'. However, the bit that intrigued me was how you accommodated the adjustment required to the distance between centres for the one tooth increase in the smaller gear. How difficult was it to ensure the gears would mesh together properly after machining the bearing seats and re-assembly? Brilliant video and the whole execution of the project by the way. Great to watch.
Cool project! Turned out very nice ! 👍
Thank you very much! I use it a lot. It's extremely helpful when having no digital readout.
Majitelia malých sústruhov robia len tuning. Na iné nemajú čas. Inak pekná práca 👍
the engraving indicator and also the jig for the numberstampig are quite neat
Nice work. Using your lathe as a shaper/broach/engraver. Liked that.
Thank you very much! Yes, a lathe is extremely versatile :)
Forgot to say: a lovely piece of work!
Thank you!
That looks totally pro. Well done.
Pretty slick. Well done.
Amazing work !
I like how you tackled indexing the dial without using an elaborate tool (like a Dividing head).
Thank you very much. Yes, this method worked quite well.
Serious skill. Nice job.
Outstanding job!
What a fantastic execution of this project. Very clean and neat work. It's sad that we all buy these Chinese Mini-lathes and then have to spend so many hours to fine tune/modify them to work correctly. If you calculated the hours it takes times your labor costs, we spend more money fixing them than they cost! lol!
Putting in the effort, overcoming difficulties, sometimes having to improvise and (not always) being happy with the result are all integral parts of this wonderful hobby :)
Dem Ingenieur ist nix zu schwör👍 Exzellente Arbeit 💪
hehe, genau :D Vielen Dank, freut mich!
Superb handle markings
awesome build, thanks for sharing
Thanks for your comment!
Yo! Im loving i found this channel! One suggestion tho. If you talked us through the build or just your thoughts throughout the build i bet this channel would kill! Anyways, keep up the awesome work!
Thank you very much for your kind comment and feedback! I really do appreciate that! In my latest video I started talking for better explanation. I think I will do more narrated videos in the future as some suggested this too :) Thanks again!
Great improvement, looks great..
You do amazing work!
Thank you very much!
After reading your detailed description, I totally agree that the carriage feed handle and the cross slide handles are to close to each other to begin with. Your new bigger and batter carriage feed handle makes this issue more pronounced than before, but I know you can make it better than new.
Há profissionais que estão em outro nível, realmente incrível esse trabalho...🤩👏👏👏
Muito obrigado :)
