- Part 6 of Quick Change Gearbox Build: The Finale!
In this video we assemble everything, (then reassemble it multiple times) and do some testing
Note that the gearbox is very noisy due to the input gears. These are my first ever gears and a re a crude involute profile making them load at speed. There are also some shafts that I will fix up as they are slightly undersized and the gears rattle a bit in the multiplier assembly at speed.
My biggest regret is the paint colour not matching!
I've gone for a slightly different style in the video, trying to maintain the flow, but turning the pace down a bit to get some more concepts across. Let me know if it does or doesn't work!

By popular request, at some point in the next year I will try to put together a 'proper' narrated version of this build
500 to 8.5 thousand in a year! That's crazy. Also great job on the gearbox.
@@greasysteve5671 you know that's crazy now you mention it. It feels like this was over 2 years ago, but it's not!
Thanks for watching!
i just stumbled across this series I can't imagine having to wait 8 months for the conclusion watching them in suggestion made me want to slap somebody for the hell of it
No words! Hats off to you, dude!
Cheers! It's been a long build
It takes lots of patience to achieve this. Lots of patience. You are an artist.
You never gave up. I can't imagine how difficult it was to build this. Good work
Yeah, I'm keen to work on some smaller builds in the near future!
Yes so great really glad we are not going to miss this final of the build, watching well to enjoy your efforts to make this gearbox. That must be a really nice feeling being able to thread so easily now, your work is nice to see and see you here as well, nice to meet you. Congratulations on the shed addition as well. Lance & Patrick.
Thanks for doing this, you are seriously one of my favorite workshop/building channels. Keep up the great work!
very awesome. cant wait to see it covered in!
Yeah there are still some things I want to sort out, then I'll cover it in
I feel a bit lost now that it's 'done'! Onwards!
PATIENCE & PERSEVERANCE!!!!!!!!!!!
Well done!!
Ha that's pretty much how it was completed with screaming forceful determination :)
I need to tweak minor things soon but it's working well
Thanks for watching
That's awesome. Well done mate, I love the functionality, threading to fine feed with the flick of a knob would be a dream
Oh yeah it's going to be great! Threading is no longer a painful experience
Awesome. Project completed. Thanks for sharing.
Cheers! Putting it through it's paces and it's holding up!
I plan on a quick follow up soon
It's alive! Really complex thing. You cool!
Human ingenuity at its finest. Nice!
Cheers! Got there in the end
ide yg sangat brilian,moga makin banyak ide2 kreatip nya kawan,sukses slalu👍👍👍
Very cool build! You should be extremely proud of yourself for accomplishing such a build. I am sure it required a lot of patience as you had to assemble and disassemble multiple times. Great job. Can’t wait to see more videos
It was very frustrating! That's why when I was far enough through I decided: "All looks good and fits, it's getting welded now!"
Great job Tommy! I had the ideal just this week that maybe I should design and build a quick change gearbox for my little lathe (Seig C6 Hafco Al60). I did a You Tube search and your video series came up first. Well I think your work on and off the camera easily earned a sub. All the best.
Cheers! It was a lot of work, but I'm glad I did it!
Man! I loved this series ❤️
Thanks for watching 😁
I love it!!!!!
congratulations friend you and Master's magnificent work 👏👏
Wow, that's quite the project!
Yes I'm a bit crazy for undertaking this. I plan on revisiting this soon
@Tommy - that was an awesome build! Really enjoyed, learnt a lot,
Thanks, glad you got something out of it!
Bro, very impressive. Respect!
Thank you! Cheers!
New subscriber. Love it!
If Chris and Tony had a baby....
Ha ha thanks for watching!
Absolutely brilliant
Cheers!
excellent work
Thank you!
Well done! I’m a big fan of unreasonably complex shop projects…and gear making.
😁😁😁 I like to challenge myself
The new OldTony 2.0 improved version extension pack.
Nice job btw. Love your style of being fun, having fun e job's done.
Unreal!!! Great Job! I can't believe someone would give you a thumbs down. They clearly don't know how difficult it was to make.
Yeah 8 months of my life I'll never get back, but it's very useful!
Great project, well done. You’ve impressed an old jaded man. Hats off mate
Ha ha. Cheers
Bravo!
Hard work, good result.
Cheers@ I nearly went insane!!
I'm actually building a gearbox for another project soon lol
I had to comment before I watched the video saying I have been very impatiently waiting for this video!!
Ahh quality takes time! As does rework lol
Wow, watched the whole series 😁. Might have to rigidify the housing at some point but amazing work man! 👍😁👍
I have more issues with the longer gear shafts flexing at higher loads. I will need intermediate supports for the problem areas at some point in the future
Bloody beautifully
Cheers! It's been very useful so far
Amazing build! I have a logan lathe I bought without the apron/lead screew/change gears :-( I have also been wrestling with ideas to get it to a point I can thread...probably gonna keep moving forward with a crude chain drive system...only took a few days to setup its most basic elements
Bravo bel lavoro!
Grazie!
Congratulation.... a realy piece of art..
Thank you! Cheers!
Very good!!!!
Thank you! Cheers!
Brilliant!
Cheers!
Complimenti vivissimi. È un po' che sto pensando di costruirne uno per il mio tornio, ma ora dopo aver visto il tuo lavoro, mi metto subito all'opera. Grazie per i tuoi video, purtroppo non capisco la tua lingua...
Provare Google Translate! Grazie per il commento. Potrei provare ad aggiungere didascalie in futuro. Proverò a ottenere alcuni piani base per questo cambio nei prossimi mesi
20:30 "mexican sand off" - killed my XD
I couldn't resist :)
Great job Tommy, love the 'on the fly' mods to get things to fit-up. Strip and fit, strip and fit to get the alignments and meshings right would have done my head in, showed great patience. Looking forward to seeing the new shop being populated with machining gear. Great reveal, now what are you going to do for the 1000 subs.
Cam
Yeah once I welded the side frames it became much simpler to handle and fit. (should have done that much earlier in hindsight)
New machining gear? Now that you mention it, there have been some nice looking surface grinders on gumtree recently...
goodness gracious. I'd noticed your change gears and wondered who made that lathe. NEver seen the like before. And now I know why. Good job o work you got there.
Thanks 👍 Yes I will be doing a proper narrated version before the end of the year
It's very satisfying to see the completed project. I could feel your pain each time you discovered a new little hickup that required a slight design change during final assembly. I've run into that sort of thing more times than I can count!! (Maybe one of these days I'll finally take the old machinists' advice and build a fast/easy prototype in wood or other soft material before committing my work to steel?)
Would you be open to a couple of suggestions?
If so, the first would be to build some guards to encase all of the moving parts. Open gear trains are ridiculously dangerous to work around. Covers also keep swarf from chewing up your gears and bushings.
The second would be to coat the inside of all the guards in rubber and/or some dense foam to deaden the gear noise you mentioned. Simple aluminium sheet stock attached with small countersunk screws tapped into the side plates would work well. Making a one piece guard for the front and top, and hinged at the back would allow quick access for occasional oiling - and for showing off your creation to envious onlookers!
I'm looking forward to watching the rest of your videos. Happy machining!
I agree, it needs a guard. I have a few things that I'll adress, then I'll cover it in. That will happen within the next couple of months
Thanks for watching and commenting
WOW! That was a great job. Thx a lot for taking the time in sharing your design and build. Glad to see you used CAD. I love being able plan with a CAD tool. Even though it ain't perfect it sure does cut down a lot of mistakes.
If you are interested, Wade'o Design did a conversion which I think is a great way to do it. He ended up with the best of CNC and manual. He can use his lathe in CNC mode when he wants and he can use manual mode when he wants. I thought having both modes is the best way to go. I believe this will be the future of Lathes as well as other machine tools. Right now the mfrs are milking the CNC modes for as much as they can for as long as they can, but it won't be long before that business model will be gone. The mfrs will have to have to some outside pressure to drop their prices and CNC/manual machine tools will come to be.
Again, thx for sharing your great build.
Hmm ... love your gearbox! I have a LYLAK (a what?) - it does OK; I've had it for 30(!) + years - still goes well: new drive change belt (link belt saves disassembling the lathe to put a new on eon...). I've loaned it out a couple of times (learning curve there, that one). Since I've been watching YT vids on machining, I've gotten a new zest for the machining trade!, though I am not a machinist - retired, still learning. I've discovered transfer punches and screws ... and other goodies, and discovc ered what some of my older (I was young then) tools are for!
Let me welcome you to machining then!
Warning: it's highly addictive
@@TomMakeHere Yes it is!
Good 👍job.
Thank you! Cheers!
Incredible persistence! Why not use a 3D drafting app first? Design, interference test, etc all in the model. There are plenty free open source apps out there. Saves you most of the rework and your plans will be done first and updated as you mod the design.
this was modelled in solidworks before hand, but there were a few things I missed, and there were also improvements that were apparent with a physical model in front of me as the build progressed
Also, the way I was meshing the shafts by feel, they didn't necessarily end up where I inteded
Its so nice to see a talented mechanic sharing their work so nicely! I'm not one, unfortunately. I have no skill at all, but I have great ambitions. Let me explain my case so you can maybe help me: I have a farm and work on it like a mad man. One of the requirements is transportation of goods(fruits and vegetables mainly, but occasionally stones and wood for repairs and building). I do have a tractor, but using it is often overkill(I could, but it serves me better for plowing and harvesting). So my idea was to develop a cableway, but I'm struggling with the design for the "thing where I'll load the things into"(don't know the name for it). The cable itself might be very long and will need plenty of support along its way. The question is: How to make it roll on the cable and also be able to pass through/over the supporting pillars? If you could help me on this one I'll be very thankful! Just to try and make it simpler: Its like a ski lift, but for cargo.
I believe ski lifts have rollers top and bottom that clamp around the cable, but the top rollers are spring loaded to move out of the way. The carrying container would need to be crimped onto the cable and poke out the side of the cable, go down, but then the centre of the basket be under the cable so it pulls straight down.
But I would think a conveyor belt would be an easier option. I have another idea somewhat combining the 2 ideas, but it's a bit difficult to explain. Do you have an email? I could send a sketch
@@TomMakeHere Sure thing! kerplunkboy@gmail.com
This is where you have a buddy with a plastic printer to do most of the prototype work for fitting. In the end there's nothing going to replace making the real deal.
Or get more than 85% through the design before starting!
I was sick of designing and wanted to start the build with the intention of adjusting as I went
I was looking forward for this. It's fantastic! I thought the gearbox needed to be wet. Won't it suffer premature wear?
It's not running at crazy high speed, and I squirt oil on everything before use. Thanks for comment
So, the fully oil tight enclosure and oil pump is a future project, then? 😀
An electronic leadscrew would have been so much easier see TH-cam (Clough42). Cost about 150.00, with that said this is a mesmerizing toothed puzzle, I wouldn't even know how to start! Awesome work.
I agree. I was finishing this when Clough42 started his ELS. I considered electronic early on, but my PLC knowledge is currently limited to arduino and its processor is nowhere near fast enough for this. I believe Clough42 actually mentioned this.
It certainly would have saved me a lot of work!
the master of half fast
Thanks for watching
Great job. How much extra power are you drawing from the gearbox attachment?
It's a bit hard to measure, under normal feed (not threading) I can turn the chuck quite easily and drive the carriage. Fully disconnected there is very little resistance through the gear train unless in a threading selection
When you were doing this project, did it cross your mind that this is the steps the old-school dudes took to build one of these? I'm building a milling machine and wonder that a good bit. Being its the 1st of its kind. The trial and error. Grinding and fitting. I know you know what I mean.
I sort of did, thinking it's a stupid project to attempt, but on the other hand someone did the same once with the first one. I learnt a hell of a lot doing this and would change a lot of things now
Good luck with your mill, that would be a great project
If you put a complete cover over your fantastic gear box .
1) keep hands safe from gear eating flesh.
2) keep shop dust, metal bits, food from gears.
3) some kind of oiler spray pump
4) another place to put stickers / identification tags.
OR
Just let the chips fall where they may.
😬
I do plan to sort it
For now I just stay well clear of it during operation
Thanks for watching and comment
Haha Haha love you very nice
Hey tommy, GREAT stuff! I'm thinking of doing the same to my little atlas 10", and i've got most of the 'know how' but im struggling with the gear ratios that i wanna put in, could you tell me how you figured out what feeds you wanted to put in the gearbox, and the calculations?
Cheers, you earned a sub btw!
Geargenerator.com is a great way to check the rotational speed. You need to consider the pitch of your leadscrew, and consider how far the carriage moves per revolution of the spindle
👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻
😀😀😀
Can you share the gear schematic?
5 x Packs (of ten - is that where often comes from??) - oops, all right - been there, done that ... it's called tricks for young (and not so young) players!
Well it went from an ok-ish deal a crazy good one! I just need to find projects to use them up now
'often' ha ha I like it
Tom,
Now that you've got enough bushings for 9 more QCGBs, what 9 projects do you have planned for them? ;)
Is your gearing spreadsheet available for download?
I _remembered_ to click "Subscribe" with this video!
I've certainly got enough for all forseeable projects
Send me an email tommygmachining@gmail.com and I'll send you a copy of the spreadsheet
Thanks for watch and sub!
Are plans available?
Send me an email tommygmachining@gmail.com and I can send you a 3d model so you can adapt the concept
Do you have a autocad drawing with dimention
I've got a solidworks file, but I can convert it to pretty much any format. Do you have full autoCad (not just AutoCad LT)? If so, you will be able to work with a 3d file
Flick me an email tommygmachining@gmail.com
SQUARE THREAD😆😆😆😆
I might have to make a 'hex bolt' next :)
Can you make a 8 speed sequential high speed gear box for a diesel engine?
Technically anything is possible, but too much liability and beyond my current capabilities!
@@TomMakeHere dear please make e project on 7 speed sequential gearbox 😅😅
Thanks for watching
jesuschrist!
Maybe we can get your cyborg cat to play with my cyborg dog.
Lol dogs are better anyway
R u there on Instagram ? Would like to follow u
Ah no, just here for now. I post the occasional update in the community page
Great build and pretty well thought out product, it’s was very interesting to watch the progress of this project, it was very difficult to sit threw all of the bad jokes. So summing up good machining skill’s, better than average fabrication skill’s but far below average comedy skills. Congratulations on the build but leave the jokes to old tony
I'm working on a proper narrated version without the jokes.
At the time I didn't think the project would be interesting (it's just holes in plates with shafts and gears after all) so I had fun with it, I got positive reviews at the time and over did it lol 😅
