wow. The current videos, made three years after this, show a tremendous improvement. Karen as certainly learned to be a master of her craft over that time.
Watching these older videos I think "Why isn't he using the..." and then I remember that wasn't a thing yet and it amazes me even more, how far you have both come in only a few short years. Well done and many more years to come.
Viewing these older videos shows how much Karen's videography and editing has improved. The viewing angles, zooming, slow motion, time lapse, sound etc. have become much more sophisticated and professional IMO. There is nothing wrong with these but her current videos are far superior to the "standard" videos on TH-cam. Kurtis's skills are always impressive and not being a machinist, I can't find room for improvement. His work is always top quality and professional. Together, your skills produce a wonderful, educational and entertaining video product I enjoy watching over and over. Thanks!
Its great going back through the archives to take a look at the early videos. You guys are smashing it out the park glad our business is doing so well.
I mentioned this once before. Seems your older vids are the ones that have music.
These are so much more enjoyable with just your narration or the machine sounds.
And of course, Homeless grunting. Hahaha.
thanks for always giving context to the part, it turns it into an actual part we can know about rather than just another piece of metal. Great work! makes me excited to start my apprenticeship seeing the kind of chips you make :)
Hey mate thanks for watching glad you're enjoying the videos. When are you starting your apprenticeship? All the best with it! 😎👍
@@CuttingEdgeEngineering Just this monday actually, got the job offer and everything. It's millwrighting so your videos share a lot to do with it, machining is always fun and seeing the metal turn into a functional part is probably the coolest about it. Thanks for all the content, I learned a lot just from watching already!
@@CuttingEdgeEngineering Just a little update, I'm 4 days in so far, 46 hours on the clock, will be 60 tmrw, having lots of fun and learning a shit ton. this is definitely going to be a fulfilling career, the industry awakens something inside me and it's awesome. time to get er' done and make stuff happen, best of luck to you and your business :)
Been watching you since beginning. You and Karen do a great job on your downlosds. Keep up the great work. Hello from Texas Hill Country.
Great content I love to watch the chips fly. I am a 34 year tool maker and it is great to see how other country's do turning. I work with a lot of carbide and hardened steel as well as brass and soft steel. I make dies for cold heading. The company I work for started Torx Products in Rochester Indiana. Keep up the good work.
A little Antebellum playing in the background. Nice!
Nice work as per usual Kurtis. Love that 3 jaw chuck you use on the tails stock end. Cheers, Aaron.
Hey Aaron thanks buddy appreciate you watching. Yeah love the tailstock chuck definitely comes in handy with all our re-barrel work. Cheers, Kurtis 😎👊
It is pleasant and interesting to look at your work.Greetings from Russia, I am also a Turner.
Hey mate thanks for watching from over there! 😎👍
Super 5 stars , excellent
I use to work for a company and did machining on a daily basis with tolerances of +-.0002”. We used diamond grinding wheels. 600 grit and 320 grit. I find it calming to watch you machine as young as you are. You must of started young. Thank you for putting these videos on TH-cam. Thank you Jeff K
Hey Jeff awesome mate thanks for watching! 😎👍
PUY !! SOME !! COOLANT !! ON .! IT !!
Subscribed !!! I'm hooked looking forward to many more videos keep up the awesome work u guys do !!! Cheers mate from cali
Hey welcome to the channel thanks for the support! Cheers, Kurtis 😎👍
Nice job 😊👍
Jeasus mate. Three jaw on back bar.
Awesome
Nice!!
Hey Kurtis, thanks for the vids, great to see an Aussie machinist doing real work on TH-cam! I'm wondering what are your typical tolerances for these big parts your working on? Do you go to tenths or hundredths of a mm?
Happy 4th you guys SanAntonioTX
Nice job, videos are great. You'll have to take that tailstock chuck apart for 'maintenance' and show us how its mounted to the MT arbour.
Hey Ben cheers mate thanks for watching! Yeah got plans to do a "how to" video on making and using the tailstock chuck 😎👍 cheers, Kurtis
@@CuttingEdgeEngineering looking forward to it, I've been collecting chucks and some material to make my own. seeing how yours are made would be helpful

Hey Kurtis.
Nice work man.
Looking forward to watching Part 2.
Keep those Bananas Bent.
Haha cheers Peter! Thinking of you all down there mate
@@CuttingEdgeEngineering
Thinking of you ( well not you directly, lol ) about being up North.
Looking forward to stepping off the plane in Cairns for sure.
Hey mate when are you hoping to head up there? Hopefully sooner than later
@@CuttingEdgeEngineering
Hey Kurtis.
Hopefully as soon as we can escape Victoria, LOL.
Most lightly the way things are going ??
I am guessing 2021 ?
I will wave to you out the window as we fly over, maybe i can get the pilot to do a flyover, lol. ( Top Gun style )
Man I work with a lot of concentricity and lemme tell ya it’s stressful, its a piece a cake with open concentricity.
Great work! Can't help to wonder if it's possible to do the same process with a much heavier part black as forged🤔
Excellent videos and educational for a non turner. On CAT parts what tolerances do you work with?
I’m guessing that bore radius was cut freehand? Surprising how good you can get em with practice, though haven’t been on a center lathe in 14 years so mine would not be to good 😂 lol
So do you need to polish the external surface of the ram? Is the final cut smooth enough for the seals integrity? Seems that it should be ground to a final diameter.
You know I will say big is good but so is long with no taper eh. Nice one !
Cheers mate!
boss: Why can't you bore a bar in 15 minutes like this guy
me: I don't have magic youtube
nice video, lovely bit of workplace asmr
Hey Simon thanks for watching and commenting! Glad you enjoyed it. Yeah got to love the magic of video edits, otherwise watching hours of boring would get boring HAH! Cheers, Kurtis
So do you do on site instalation? I notice all your stuff gets strapped onto a pallet and shipped or you take it. I was just wondering what happens after that . Do you just deliver the parts and someone else assembles them or do you assemble and someone else installs
What's the trick to getting the jaws inserted in that 3 jaw chuck properly? I always had trouble with that....
I see a WNMG-16 right? what grade and chipbreaker?
how is the chuck fixed with the live center? I have to turn some big tubes/pipes externally and was lookig how to work with the live center
I made a video about it th-cam.com/video/-E1NkckJdbs/w-d-xo.html
in epidemic sound there is a referral link if you go to ME>Referral and there should be a link there
Hey thanks for that! 👍👍👍
Why are the scrapings blue? Is that from the heat?
Thats interesting a chuck in tail stock did u make that ? Any advantages more ridged ?
Hey mate, Yeah have made tailstock chucks for each of our lathes. Yes more rigid, quick setup on some jobs, also have an independent 4 jaw tailstock chuck for those odd shaped jobs.
@@CuttingEdgeEngineering bad ass thanks for getting back to me
@@CuttingEdgeEngineering No yeah good input, is it on a mt5 taper?
I noticed the cuts you were taking were finer than frog hairs. Was that because of the material or the final dimensions?
Kurtis, will this be site welded into the other component parts of the bail arm or is there a part 2 on the way? How do you get the critical dimensions of these parts?
Hey Mark, the customer sends us a drawing with the required specs and they fit it in their workshop in a pre-made jig for bail arms as they are a high turnover component on scraper fleets. Sorry no part 2 this time, maybe one day! 😎👍
Hey Jacob welcome to the channel mate thanks for watching. Work within OEM tolerances which is tenth of mm but generally get as spot on as possible. 😎👍
steel is now a crazy price in Au, Alu abt the same as in 1990 ,6000 tonne, where do you buy 4140 and bisalloy and Valoric hollow bar without being screwed over and where do you buy tooling, inserts etc, would appreciate guidence here from anybody
Hey mate yeah you're not wrong just got an email from a supplier that steel prices are increasing 5% soon. We get alot of our material from hydraulic steels Australia. Also use Vulcan Plate. We have high volume so do get looked after with pricing. Get in touch with Arthur at Livetools in NSW for all your machining tooling! 😎👍
@@CuttingEdgeEngineering
Instead guys smuggling drugs it will high quality steel
I wonder how much the CAT price would be for such a part.....give up your first born child etc
Yes or a liver, maybe a kidney
You mean DOM tubing?
Chamfer angle????
More music by the equipment, please.
You never show how you calculate your final measurements for the bevel for welding prep. It has to be exact since you have an end product measurement . I’m quite certain you don’t guesstimate it.
Also wondering why you haven’t built an easy rest for when you are using the the special portable line boring equipment? You said you put your hand on it to reduce the vibration. Am I missing something?
is your staffie a blue??

Hey mate yeah he is
@@CuttingEdgeEngineering Beautiful dog and i love watching your work you are one of the chosen few just get on with any problem fixed love your channel
FFS why do boring bars ALWAYS have to be made so you can barely get centre height on a manual machine? Seriously I've never used one that you didn't have to pack to the top of the tool post!
Hey mate hearing ya have the same problem. Have asked most of our tooling suppliers and get the same dumb shit response "they just don't". FFS
@@CuttingEdgeEngineering I think the designers aren't aware not everyone uses a CNC
