Very interesting video. Thanks. I’m sure this is going to help me when I eventually buy my milling machine.

Hi lLukeR, just wondering if you have a recommendation for the grade of oil you use in the gearbox - I 'm sure it is a contentious subject - I know everyone has an opinion on oils, but just interested in your thoughts. I use an ISO68 hydraulic oil in mine - same mill, just branded differently. Thanks.

Thanks for the idea of solder on a boring bar - I'm gonna use that one.

In engineering terms, he is changing the resonant frequency of the system. Most of the attempts to stop chatter I have seen focus on increasing stiffness of the system( the stiffness of the tool post), or of increasing mass of the work, in an attempt to move away from the resonant frequencies. I have done both in the past, sometimes successfuly, sometimes not. As an amateur machinist and retired Engineer, I had simply never considered that adding mass to the TOOL ITSELF might be a possibility. TH-cam once again comes through with sharing practical knowledge about practical things. I will give this a try very soon.

Unfortunately my Dad is not anywhere near as meticulous as you when it comes to cleaning & maintaining and my ongoing project to get his lathe in decent order is coming along slowly. It is great to be able to watch as you confidently move methodically along. The gearbox oil is black and needs draining, your very neat trick with the paper is going to come in handy although on the smaller lathe the drain point is more convenient. After draining & cleaning with paraffin is any residual going to cause problems?

Great advice, good maintenance is key to long life. Good design is another important factor. My 70 year old Colchester student still going strong.

Thank you for this series, incredibly informative. I've not built a boiler before but was intrigued as to why stainless was not more commonplace compared to that of copper, this series has answered my questions perfectly.

Please stop the speeded up dialogue! Content is generally great but would be good to actually get through one project rather than jumping around so much!

What brand of lathe is that? I have a Craftex 709 (13×24) and it is identical to yours.

Hey Luke, just seen this. I thought the pretty patterns were referred to as ornamental turning ? The idea of solder round a boring bar is really neat. Your a braver man than me - inducing chatter like that, I was waiting for the bar to jump on top of the tool. N

Hi you can try traveling steady and grind a lip on your tool

totally agree...and clean them ALOT

Nice work. Good old fashioned no-nonsense South African work ;)

Anti vibration wire? Solid core solder maybe? That alone is a good tip. Using some lubrication and altering lathe speed helps, as some inherent vibration is caused by the lathe motor. Making sure your centers are in tight at each end and/or using a live center instead of a dead center will also help. Headstock bearings OK? Last resort is, as you say, reading Machinist's Handbook, as we like to solve problems on our own!

Looking forward to the casting series. Enjoying your series as I am building up my skill set to construct a live steam loco. I'm in no rush and its great that you are a fellow South African as all the other great channels are typically from North America or UK.

Hi Luke, my dad has a Mac-Afric lathe that I wanted to start learning on, however I could not get a good smooth cut. Long story short, after a short investigation I realised he had run the carriage into the chuck & the alignment is now out, so much for learning to use the lathe, now I am learning how to strip it! I am assuming the bearings will need replacing & alignment on the chuck shaft done, but I cannot figure out how to remove them, any suggestions? Adendorff here in George were no help sadly.

Conventional wisdom would never indicate the lathe as the problem when you are turning a part that long and thin for goodness sakes. Use a follower for what they're made for and wala. Oh and actually clamping one end in the chuck instead of between centers cuts down on chatter.

Have just bought same lathe, thank you for the well explained video.

Your anti-chatter wire seems extremely effective. I'll have to give this a try. Great work.

Great channel. I have learnt something from you, and I was a fitter/machinist for over 20 years. You seem to be somewhat different from most other engineers. I will definitely continue watching your channel. Thanks so much

Is your lathe levelled and bolted down? Mine is neither of those things :( I managed to build a working loco with it, but everything has a taper, including the cylinder bores.

You make it look easy! The casting process is very interesting and that loco is superb!!!

The finish straight from the mold looked amazing!

Wow. Great work. This is work on the next level.

I have never heard of chromite sand. What do you use for cores?

man, no

Thanks for taking the time to video this and post it. The casting process fascinates me.

Great video. So looking forward to your casting series for the new build we are following

Nice work!

Great tutorials!

Great videos. It’s going to help me a lot with the steam engine I’m working on. Thanks. I forgot about this, been reminded by a fellow tuber and countryman “Improvisediy”.

Excellent channel Luke have a look at my fixture for steam chests.

This is a great video! One of the most thorough and informative videos on stator replacement I have seen. The gasket making portion was excellent! Machining new parts, improving the design and lubrication, that is so you Lukers! Many other great tips and procedures! Love it! What material did you use to make the gasket? Great job! Ride Safe!

As a new owner of a combo lathe in good condition, I as well as my neighbor who is a retired machinist tried everything we could think of to stop chatter in some projects with minimal luck. You just opened my eyes to a new approach. I never thought of copper or lead wrap. Thank you for the info and the detailed explanation.

Driving on a prayer! You were lucky.

Excellence.

Just putting this out there but if you had a Gold wing I'm sure this problem would not have arisen or lets say a BMW RT100R. Just saying my mates are forever fixing their Harley money pits while I just keep on rolling. Quality over quantity if you expect to get home.

Too much overhang of cutting tool give rise to vibration

Hi sir, Can you please make a video to guide you in performing finite element analysis simulation on boring tool when machining, I really want to learn from you, thank you for making this video.

Some bloody good tips ‘n tricks there mate 👏👏👏 I’ve got my ( gunmetal) cylinders bored and externally machined. Just about to start the porting…. so your insights are timely. Looking forward to the ‘valve’ video. I think you mentioned that some discrepancies on the ports can be ameliorated during the machining of the valve. Great stuff on the piston/bore fitting too. I’ll twig my order of operations to follow your logic ( re. ‘burrs’). Once again, Thanks. Robert 🇦🇺

rubber bands!

They make lead tape for altering the swing weight of golf clubs I wonder how well that would work especially on a long stickout boring bar.

some great tips there Luke👍

Great stuff LukeR, really enjoyed that! 😊
