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👍

Добрый день шплинт ставить обычный или пружинный mashine dowl spring a not spring?

Great stuff LukeR, really enjoyed that! 😊

Very nice and detailed video! I want a milling machine like yours! 🤤

Very nice and detailed video!

Fantastic video LukeR, some of best machining advice I've seen on RUclips in a long time. Many thanks for sharing this info, much appreciated 👏

Same principle to eliminate anvil ring by wrapping chain, setting on a bed of silicone, and/or sticking magnets to them. It changes the frequency.

Very nice work sir. Lekker man.

Despite being born in the digital age, I am obsessed with model engineering. I would even love to be a part of the craft, helping keep both the interest and a piece of history alive. I'm excited to see all of what you yave planned! ⚙️

I’d love to see a video about the home casting. I would like to be able to produce my own castings in cast iron for model engineering projects. I can’t find a good source of info for how to achieve the temperature to melt cast what to add once it’s melted etc.

Baie dankie, Gaaf van jou.

Great tutorial! I use my 123-blocks to square stock in the chuck. I will remember the wet rag hack. I would like it if you could discuss press fit tolerances as well (not everyone has machinery handbooks).

May I ask your opinions on a couple of points. When it comes to machining cylinders, I take a clean-up cut off the valve face. Use this to align the 90 degrees, then cut the front cylinder face, then the rear and bore so that the bore is true to the rear cylinder face, pretty much as you do. Then I take the casting and put it in a mill with a rod the same size as the bore and tap this down in the vice. Then I can measure from the top of the rod and machine an accurate distance from the centre line of the bore to the valve face, with a bit of maths. This would seem to be more accurate than your masking tape method? I'd love to hear your thoughts. Secondly, and probably more straightforward, would the be a problem with using JB Weld to fill an inclusion in a casting rather than sleeving? JB Weld is rating to 260C, but I don't know if there are other factors that I'm not aware of. Thanks for taking the time to read my lengthy comment.

I love your type of attitude towards model engineering, so glad I found your channel

Very nice work sir

Best video for my apprentice to watch

Fantastic channel I'm learning so much

This is a great channel. I always look forward to seeing your process.

Hi! Can you share how to make an inertia piston? Is it possible to use a 1-way spring valve, albeit modifying the spring to make the valve more prone to vibration?
