DIY composite pulley for the home made lathe [part 11]

[@f.g.hammer6814]

The egg came first this is clear. Great job!

[@Igor-nx8uf]

big jump in video quality! music, editing, great content 💯👍

[@AccidentalScience]

Thank you. I really appreciate feedback.

[@rameezsheikh7576]

Title grabbed my attention 😄👍

[@kolbakolba]

It's pleasure to watch, every video shows different vision to make something, aluminium chips, epoxy, this channel show another perspective to made something.

[@AccidentalScience]

Glad you enjoy it!

[@alxvlx9020]

Отличный токарный станок получается!

[@TroubledTimes2024]

OK, that was impressive and just goes to show that ingenuity and need are often more important then the equipment.

[@peterfowler8044]

I think there's still a few of us that would like to see the finished lathe in use !

[@AccidentalScience]

@@peterfowler8044 I am one of them.

[@couldhaveseenit]

Wow so much patience. Just now wondering if you could have wrapped the belt around the chuck and driven it that way.

[@AccidentalScience]

What do you mean? May you explain better your question? Tnx. EDIT: Nevermind, I misread your question. Answer in the comment below.

[@AccidentalScience]

Oh nevermind, I misread your question. Yes that could have been a possibility, I actually didn't thought at it maybe because it would have been trickier to keep the belt in place, and there is no room for the motors behind the cross slide.

[@jackskalski3699]

Wow do I see correctly, that you use two motors to run that spindle? Isn't there an issue with RPM discrepancy between them?

[@AccidentalScience]

No, it exploits that 😉

[@lumotroph]

Incredible

[@flavienthuez8423]

Nice ! You always surprise me with your use of composite material 👍 For the Q&A : do you plan to do some other machine ? Like a mill, shaper... Do you wang to get involved into CNC ?

[@evugar]

I'm sure this man is single-handedly able to bootstrap civilization on Mars!

[@AccidentalScience]

Hahaha :D Thanks mate.

[@atiger4716]

Beatiful, thanks Sir for sharing your exoerience

[@athrunzala5337]

a small visit to the scrapyard you will find all the pulleys you want and for cheap

[@AccidentalScience]

You are lucky to live in a place where people can go to industrial scrapyards, but yeah it could have been a good idea. Thanks for commenting.

[@watergeting8586]

Easiest way - go to car mechanic- they change pulleys everyday, difrent shapes ,types, sizes.

[@tripledldiesel]

I wonder if instead of trying to turn a part with a pulley-less lathe with a scraping style turn tool, if you mounted something like a dremel to the tool holder and instead sort of psudo ground the part to size using the lathe ways to keep accuracy. Thus changing the torque baring portion to the fixed dremel instead of the belt of the lathe.

[@AccidentalScience]

That could have been a good idea.

[@rikujkoivisto]

Hi there, and greetings from Finland!! I did subsgribed your channel, because you kind of think same way like i do. Many different expearments, and way, you try to made almost everything by your self.. Your belt bulley, that you mase of resin, and chips of aluminium is brilliant, but those chips may eat the drive belt. What you think? I recomment to (paint?) the pulley or add resin layer with paint brush..?? I know you find a way to result any those small problems, so i want to thank you for VERY VERY GOOD videos, and may our God bless you and your life.. Thank you!

[@AccidentalScience]

Thanks mate! Definitely your advice to cover the pulley with a layer of resin is a good idea. Greetings from the Alps.

[@courierdog1941]

I like your concept. Firstly I realize using this method you can have what ever size of a Spindle bore you desire. creating either Spindle Pulley(s) or Spindle Gears. I have to watch the rest of this video before I miss what you have done Next. I am a huge proponent of "V" ways for accuracy as opposed to Flat Ways. But Your Spindle concept has me very interested. Back to the Video. Again I would be using Taper Bearings which have a means of tightening to reduce the Run Out.

[@AccidentalScience]

Good point about the V ways, I have to keep this in mind for the next Q&A video. Cheers.

[@peterfowler8044]

Isn't it time to finally show us the lathe in action ?

[@davegeorge7094]

I was thinking same thing, it's not critical how the torque is made. Screw sync. is however is unforgiving.

[@sacriptex5870]

try to use speed steel as a tool on your lathe... its much more forgiving on small lathes than soldered carbide

[@AccidentalScience]

Thanks for the tip.

[@ultimateworkshop2000]

Did you abandon the project? 5 month no videos, we are waiting 😄

[@robertsteinwandel6658]

Hope you’re doing well! A few months ago we talked about designs for the ways and cross slide, Im building a lathe as well (although a bit slower than you unfortunately hahaha). One thing I have thought about, have you noticed any creep in any of your welds from the heat stress? I remember you machined the body after welding to get such nice surfaces, but I can’t remember if there was any movement in the welds long term? Absolutely beautiful project and so amazing to see it getting so close to being complete!

[@AccidentalScience]

Thanks bud. I'll try to go deeper into this point in the next Q&A video.

[@craftzars]

Yeah best practice to relieve internal stress is to heat all part after welding. Perfect if you can put in furnace and keep part at 650c for hour. But i seen some russians just throw all lathe in campfire and burn it good, but thats little brutal.

[@rameezsheikh7576]

@@craftzars give any link to those Russian video!

[@BSpinoza210]

@@craftzars I think it's fine to roast in a campfire like that, but the trick is to ensure that the hot ash completely covers the part after the fire goes out. There's enough insulation from the ash that the cooling process is very slow which is good for stress relief. You can even mold glass bottles into ash trays this way, as my grandfather once showed me, but you really need to make sure the coals and ash cover the glass completely after melting it otherwise you just get a pile of broken glass!

[@PEGuyMadison]

Are you on vacation or have you stopped making videos, just curious... they are entertaining and I would like to see you finish the lathe at some point! Cheers, I hope all is well.

[@AccidentalScience]

I'm relatively fine thank you. I am on vacation and busy with work at the same time. I'll come back at some time. Cheers.

[@ronbianca1975]

Another good video! Do you use a design program for your projects? Take care my friend!

[@AccidentalScience]

Yes, but you'll be surprised. If possible I'll address this at the next Q&A.

[@mrcolobike]

great job ! When are you uploading a new video about the lathe At least some update about the state in which it is Thanks Happy 2023!!

[@AccidentalScience]

I'm not able to tell a date, every time I try to set a deadline it is messed up by something else, more urgent, more important. It's frustrating. Happy 2023!

[@PeckhamHall]

When are you coming back to doing lathe videos? I really liked them

[@AccidentalScience]

Thank you James. I'll do my best. I'm busy with some other commitments and I am exporting from the old website (that never worked as intended :/ ) to the new website, but going through a lot of articles is kinda pain in ...you know where.

[@ultimateworkshop2000]

Any updates on the lathe?

[@AccidentalScience]

Short answer: no. Long answer: while I am using it occasionally in a very crude way, to complete the lathe I need some electronic components that are still on the bench of the lab. So next parts will be more after electronics. Thanks for commenting and the interest in following this project. Greetings from the Alps.

[@hueinismo1]

Nice. How much you spend total comparing to buying a new lathe of the same turning diameter and length?

[@AccidentalScience]

The lathe is not yet completed so I am unable to give the costs at the moment. An estimation is that It will be certainly more expensive than a chinese lathe, and way more cheaper than a high quality lathe. But this lathe is designed to be a midway between a manual lathe and a cnc lathe. At the moment I am stuck with the linear encoders that I ordered many months ago and that have not yet been shipped. The pandemic has caused severe setbacks with this project. I'll make a Q&A video in the future, addressing many points, including the costs.

[@MagnusNemo-xc5nx]

Any updates on your lathe? Have you generated drawings and a CAD model? Also, why did you choose sliding ways over linear rails?

[@AccidentalScience]

Hi. Hopefully soon I'll have some. About the drawings some of them need corrections but in general I have all them ready, though no CAD model. I'm gonna keep them alongside a book I'm writing. Thanks for commenting.

[@AccidentalScience]

Oh about your question on the sliding ways, as I've said in reply to the other comment I think linear ways offer less rigidity unless they are heavily preloaded.

[@MagnusNemo-xc5nx]

@@AccidentalScience Excellent. I will get in line for my own copy of your book. Any idea when you will publish?

[@AccidentalScience]

@@MagnusNemo-xc5nx thanks for your interest but it's too early , I'm at the first chapter.

[@veselinlazovic3997]

Did you publish somewhere dimensions of your lathe?

[@AccidentalScience]

The idea was to publish on my website, but the website is under development since long time. Hopefully I'll have it ready one day.

Did you ever finish this lathe?
