The release agent is what you need

Hi Mark, Very interested in your laser cutting aluminium. Can you share some specs on that machine? Cheers

I have to use shims to set my height for my tooling in my lathe, altho this video was not helpful to my situation it looks like a fun project and I will be making one soon, thank you.

Mark, well done! 😎 I was hoping to see a long term follow up video on most of your projects like the new mill or the sand muller... Jim

Beautifully machined, assembled, fitted, and finished Mark… 👏👏👏👏👏 Your patience ( and determination) is inspiring. Regards Robert 😊

You are the master of metal finishing on top of your machining skills. The etched plate is the finishing touch. Thanks for this episodes lesson.

Outstanding!! Mark, what a beautiful outcome.. museum quality 👍 Thanks also for showing the full etching process for brass plate, that’s something I’ve been interested in.. Great series! Cheers….

She runs as sweet as a nut! Now we've got a boiler build and a loco build to look forward to. I think all my birthdays have come at once!!

You have done a really good job on the steam engine Mark. 12:18 "It's the middle of winter here so the daytime temperature is only about 22". It is around 14 degrees here in the daytime at the moment. Our last trip to Brisbane was in June just before covid hit. It was like we were in a NZ summer.

looks great. I didn't see what bothered you on the fly wheel. So it's quite close not to show up on video. Great build. Thank you.

If the analog function is required simply slide the scale down until the numbers read correct

I am very impressed with the result. I especially like the plaque you made!

A nice conclusion to a great project.

Great achievement as usual! Question: would a peelable masking compound be an option to tape? Similar to the stuff used to mask pcb’s when soldering, or same as used for spray welding?

Love watching your work. Magnificent as always.

Bravo!

Lovely, but to run on compressed air is not the same as running on steam.

Well done Mark. I always enjoy the birth of a steam engine. I’ve really enjoyed the build videos, great content, nice to see your adaptations to the model. Looking forward to watching your next project whatever it will be. Always different and always interesting. Thanks. ✔️

Nice job Mark

A lot of work, but it's really worth it. It's a piece of artwork.

Beautiful work as always, Mark.

Hi Mark Many thanks for a great project. I learnt so much! Mid summer here in the UK and it's not much warmer than where you are!

Absolutely wonderful! Beautifully finished and perfectly engineered. I have looked forward to every episode of this build. Thank you.

Great series of videos with you work on the pump. Looks fantastic, your attention to detail is amazing. Thanks for sharing.

Absolutely beyond beautiful, mate! Love the color! Is there ANYTHING you can't do?!?!?! Cheers!

Beautiful finished product, a truly great demonstration of persistence and patience. Well done Preso, cheers!

👍❤👍

Fantastic. I like the colour. Well done. I'm planning a 3inch OD coal fired boiler as a scratch made portable engine so I look forward to seeing your boiler when you get to it.

It isn't difficult to think of many applications that would benefit from the "precision" filing capability possible with this set up.

Let's run this "on air" boom boom😊. Nice job Preso!

Great job. I assume you put that drive wheel in the lathe because it looks like it runs quite true. Have you ever done a video on converting that stove for powder coating?

Hi Mark, I wanted to take a moment to commend you on the outstanding engine build. Your craftsmanship and attention to detail are truly exceptional. The performance of the engine is impressive, and the finish you achieved is fantastic. It’s clear that you put a lot of skill and dedication into this project, and the results speak for themselves. Great job!

Hi Mark, lovely engine....interesting colour scheme 😉🏴󠁧󠁢󠁳󠁣󠁴󠁿

Beautifully done !

The flywheel balance is "Good enough for Australia" 😅

The finished article looks really great, your attention to detail is fantastic.

Absolutely delightful. The finished engine is a beauty. I never considered powder coating at home before - the finish is excellent. The photolith process took me back to my days working as a process engineer in a semiconductor fab - your attention to detail really paid off there. The name and nameplate are excellent finishing touches. Aaaaaaaaaaaand…….THANK YOU! Really appreciate the channel mention. Greatly appreciated!

Nice work.... curious to know where you obtained the gasket material.

Beautiful work Mark.

Enjoyed…great build/finish/video production

As always such exemplary work Mark. A most enjoyable and educational build from finish to glorious end. Well done. 👏👏👍😀

Thanks Mark. Nice tip on SM Components. Never heard of them. I had a quick look and they have some interesting stuff. Bookmarked! Regarding your power coating masking, I wonder if you could use latex to mask some of the more intricate parts like on the flywheel. Not sure if that would work. Maybe it would depend on whether it's conductive? 🤔 The engine looks great!

What a testament to your skill set Mark - not only the machining but the exemplary finishing nicely shows off the range of skills you have developed. Always a pleasure to watch and such a source of learning, hints & tips and inspiration. Looking forward to your next project. Thanks as always, Nick

Lovely looking engine

Have enjoyed all of your builds, unlike you, I came from a woodworking hobby of building wooden models as can be seen in my u tube, to now building a Farm Boy stationary engine and also the Rob Roy loco. So will look forward to seeing that build when you get back on it.

Gday Preso, I’m always amazed be the finishing processes you use, the name plate etching is something I’ve never seen done before and the finish plate is absolutely amazing, the choice of colours in my eyes is spot on and really suits the engine nicely and I didn’t know that cast iron could be powder coated, love your work mate, cheers

Worked as a screen printer (and in a dark room every day) for many years using very similar systems. Your double layer of the negative is causing your issues I'd say. Light is refracting and reflecting because the black in each image is only on one side, leaving a clear thickness of plastic allowing light to bleed. You could try printing one in pos and one flipped to get the carbon on the same side when sandwiched together or just use one.

well Mark nice process from the etching through to the powder coat and final running but i have lost faith in you now and am not enjoying your video's anymore since you did the draw on the DIE HOLDER i am sorry but have to leave now Cheers all best for your future projects 😥😢

Love what you can do! The Stuart Turner turned up a treat! (Please excuse the pun.) I used to build large telescopes, now I build tiny model ones and can share in your frustration with the smaller "fittings". I go down to 14BA with some of the ones do.

Excellent!
