Unfortunately, it's looking like it might be worth mentioning that on a scale of making a proper competition ready yo-yo to practicing my machining by making something that is yo-yo shaped, I'm pretty happy with the fact that it works at all. No doubt my design is way off - this can be attributed to not having seen a yo-yo in person since the 90's, not having time in my non-UA-cam life to properly research modern yo-yo design, not being a "thrower", likely not having the tools or skills at this point to make a proper yo-yo, and really (mostly) not really being worried about it and just having fun and making these videos for entertainments sake with the possibility of learning what to do (or not do) when using the lathe and/or (in this case) building yo-yos.
As much as I love comments, it's always a bummer to get any that start out with "You're such a f*kin idiot.." or something similar. If you do take strong offense to my video, please feel free to comment - but please be polite and useful in your comment (aka, provide a tip, resource, etc) because not only does that help not make you look like a rude person, it helps everyone else reading the comments. Thanks for watching!
Who would have thought that there would be so many people who have a problem with a custom made yo-yo not being competition ready. No appreciation for the machine work. I thought the yo-yo fad died in the 90's but clearly not lol 😂
Never touched a lathe, but after watching almost all your videos, it's now on the top of random things I wish to learn. Thanks for being an inspiration and honest. Wish you and your channel all the best!
Thanks so much! These comments are always some of the best :)
Have you considered bolting your lathe down to the workbench or to a suitable board, to make it more stable, especially when using your hacksaw?
Yep! Every time I do something and it ends up super wobbly. Eventually I will figure out something better for it.
Small torsion box that sits on three points? Keith Rucker from Vintage Machinery you tube channel has some good videos on leveling lathes, granted his lathes are huge, but I'd image the principles would still apply.
That'd work too, but it would be pretty cumbersome still and one of the main reasons I got this lathe was it's small footprint.
Well, the torsion box would be about same foot print as the lathe and still be light weight yet very stiff. You would then have 3 leveling feed, one at each corner on the motor end, and one in the center at the other end, so no rocking.
That's a valid point - I might have another video to make...
I love a good yo-yo. I'm impressed. You are tenacious and patient. My grandfather had the same qualities.
This is exactly why I want a mini lathe! Although I would've made it a mini yo-yo as well lol.
Nice job , in elementary school we had a yo-yo demonstration in the mid 60’s and by the end of the week half the school had a yo-yo. I got pretty good too. Some candy clear coat would add a nice touch. Nice vid...
I'm glad I found your video. I was going to buy a small lathe as yours. the rebuild of the lathe, gears electrical and handle would be good experience but costly.
Nice project and well executed.
Noticed the broken drill bit at the end of the video :) WD40 is your best friend when plunging a small drill bit into aluminium.
Haha yeah, a little blooper - thanks for the suggestion! I will definitely keep that in mind.
Wow great project. Brings back many memories of my child hood. If my memory serves me right Duncan was the maker of the ones we had. And I believe they made one called the imperial , and one called the butterfly. Thinking back I would guess the center axel would be close to 3/16. Not sure of that just guessing. Look forward to part 2.
It looked like the drill bit jumped up a fair bit when cutting the center hole. Have you noticed any issues related to that?
You're right and for the most part I haven't.... there's a lot of slop but it almost always will self center.
Hey! Couldn't resist. As usual sir, always inspiring. Never know what you are going to come up with next. I like that
Welcome to the compliment section!
Also, instead of eyeballing the cutoff length (for the second piece), why not use the depth meter of your caliper? Just remeber to add a tiny bit for inaccuracies... I'm also wondering about how you're going to put the parts together... are you going to rivet/bolt-nut/glue/solder... hope to see the result soon, and good luck on that handle!
I could have - I guess if I was going to leave a little extra anyway it didn't matter how exact it was :)
As for how it goes together - you'll just have to stay tuned for Part 2!
I had a lot of trouble parting off when I first got my mini lathe too. It's all about rigidity and technique. A better toolpost will work wonders, along with a thinner parting blade. That bad boy is thick! Also, you aren't using any cutting fluid, and your speed is waaaaay too fast, especially for a piece of that diameter. Slow it down, like almost as slow as the lathe will go. Like 2-300 rpm with a steady drip of cutting fluid and your results will improve. Its a slow operation on these little lathes. You should be able to get a chip going and have it curl up like a long shiny ribbon. It takes me a couple of minutes to part a 1 1/4 piece of steel, so dont be in a hurry parting a piece that big. Looking forward to part 2!
I could try getting a thinner parting tool - I was afraid of going too thin initially. I definitely could use a better tool post though.
As for the speed - that was as slow as it can go (at least without opening it up and tinkering with the pots on the board) Check out this video for more details on that ua-cam.com/video/JZgvuZGRpZ8/v-deo.html
Thanks for the suggestions though! I guess it might be worth trying to get it to go slower.
For a lot of the little stuff like this you make do you ever find and work off of a set of plans, or do you just usually just make it up as you go along?
Another cool mini-lathe project! Thanks for showing the project. 👍
Thanks so much! So far I haven't worked off of any plans... it's generally I get inspired by something or have an idea and then just think about it for a while until I have it worked out in my head how to make it - and then I just go for it :)
I've made a couple plans for some of the projects after the fact for others who were interested though, feel free to check them out www.patreon.com/timnummy
Love the whoops moment at the end.😜
Wow, a new hacksaw blade, last of the big spenders.
Only kidding, I do the same thing
Looking forward to Part 2
With bated breath I awaited the shape to form.
Nice work dude! I definitely look forward to part 2. Just curious if you are thinking about getting a bigger lathe?
Thanks so much! Maybe at some point if/when I have the space and money for it haha.
Curious to see if you add bearings.
A great project idea!
Waiting for part 2, and part 1 of the Handle making
old hacksaw blades make really nice groove cutting tools for the lathe by the way :)
Interesting... I'll have to keep that in mind.
I also have that chinese lathe and found the thin parting blade works much better, the thick one your using is too much for that whimpy motor to handle and will stall and damage the belt if not strip it........
i made a yoyo once. i design one that is diameter 40 so it can be machined on the Sherline lathe. took me 14 hours to make them but its playable even tho i made a huge mistake
Good job
Where did you pick up your"high-speed" pre-round cutting tools? I have not been able to find it on ebay.
Now I can finally sleep, ah a new lathe work video ;) Nice work man.
Thanks so much!
look at your height adjustment screw at 6.54. You should put some locktight on that.
Have you tried to use the hacksaw while the lathe is spinning? Would it make it easier on you to cut it off?
I did give that a try and maybe I just wasn't patient enough but I didn't feel like I could cut as effectively because I couldn't put any downward force on the blade. Thanks for the comment though!
@ 8:30 why didnt you use your calipers to measure the parting distance? also you really should have chamfered all the edges quite heavily to make it comfortable/safe to use.. (well you did mention that at the end but would have been much easier to do on the lathe)
keep up the good work!
No reason - I guess the other half was just closer or I wanted to show that the distance I was measuring was from the other half - not sure what I was thinking. It just had to be thicker than the previous side by any amount though as I'll bring it to the final thickness later. As for the all the edges... stay tuned for part 2 :)
Just a thought mate, I always use hss on aluminium as i find it gets a better finish, otherwise cool project ps I watched with no volume so I may have missed something....
Thanks! a lot of people have recommended HSS - I just haven't yet made the switch.
I assume your lathe is variable speed and I just noticed when you were using the cutoff tool you were running it at a super high rpm and you'd probably have some better luck with it running it lower and just putting a little more torque on your handle as long as they don't break anymore haha. Both stainless and aluminium rods I cut at 179rpm (mechanical threading lathe so the speeds are preset) with some coolant no problem. If you can keep a consistent enough feed the parts almost look faced. My two cents take it or leave it
Thanks for the comment! That's actually the slowest it will go right now. I might be able to open it up and tweak some of the pots on the board to slow it down more though. I go into more detail on the min/max speeds here: ua-cam.com/video/JZgvuZGRpZ8/v-deo.html
TimNummy I thought the case was something along those lines but it's still a nifty little machine :) your videos are awesome keep up the great work
Thanks so much! I'm glad you're enjoying them.
I'm not a machinist but maybe using some sort of lubrication would solve the issue of popping your breaker we doing parting cuts? Also maybe consider investing in a micrometer? O.o
It would possibly help - The biggest problem I think is the amount of flex in the tool post, so once enough of the parting tool is in the part it starts twisting and binding.
ah ok , ive just watched allot of machining videos and am a student welder and when doing thick cuts on our test plates our band saw is lubricated so it made sense in my mind
Yeah for sure! I have no doubt it will help - I just don't know that in this situation it's the majority of the problem :) Thanks for the comment!
I've seen a few videos suggesting that parting off from the back side of the work, with the tool upside-down, can alleviate that issue since the tool deflects up and out of the part, rather than down and into the part. I haven't gotten the necessary attachment to try it on my lathe (Sherline), but it may be more easily within your reach to give it a go and see if it works.
Wanted to say hey!
you can make good knives with old hacksaw blades.
Why don't u let the lathe run and put the saw on it would be easier to cut
Have you thought about bolting your lathe down? The lack of rigidity would bother me personally
Yes! But I'm not in a position to bolt it down right now unfortunately. It's usually not too big of an issue though
Hi Tim(and Everyone!). I came across a cheap lathe mod you might be interested in. Do a quick search on UA-cam for "Digital Caliper DRO" :D
Digital read outs on the cheap. Basically just modding then mounting a digital caliper to the carriage, cross-slide, and even the tail stock(for specific depth drilling/reaming). Touch off, set zero and away you go.
With Black Friday just around the corner you'll be able to pick up calipers for dirt cheap, heh heh. Just an idea to check out, after the carriage handle build maybe. :P
Fun yo-yo project btw,
Take care.
Thanks!
I've seen that video before and have been tempted but I'd like to see if I can come up with something a little slicker - so far I haven't been able to figure that out yet. Good idea about black Friday though, it might be worth picking up a couple check calipers anyway.
Hey
your parting tool needs to be flat, yours is shaped like a V almost making 2 cutting ends higher then the center line.
Interesting - that's how it came when I ordered it...
Mrpete222 has an awesome video about parting tools ua-cam.com/video/82LtUTBmxwQ/v-deo.html
Drawing not give
make eletro graving
First
I dare u to make yoyo using beyblade
Why do u alway let ur nicely machined parts just fall?a rag will keep them from getting nicked up ya know
