Choose the Right Material! 

Not over done by any means, I could sit and watch someone with Richard's depth of knowledge and experience all day. This really was a an excellent presentation.

Fantastic! Such an honour to be able to learn from someone with such a distinguished career. Thanks Richard for taking part, and thanks to Crispin for putting this together.

Richard is a real treasure. As a Yankee tool maker, I was familiar with all the British names of materials, save for white metal. Great video, Mr. Crispin!

Good stuff, and a great idea to get Mr. Gibbon in front of the camera. I think the most important note was when Richard, with all his experience and education, said he'd soon be taking a course on steel boiler maintenance. Keep soaking up that knowledge, folks, because we know what happens when we stop moving forward...

Thank you Mr. Gibbon, for taking time to speak with Chrispin and us as well. Quite enjoyable!

This was just lovely, _MrCrispin._ It amuses me when someone makes a CAD drawing and sends it to a 3-D printer, and think they've really made something.

Great discourse on common engineering materials, turned parts with a steel with added Lead or Sulphur, modified machining steels, would make many hobbyists and machinists smile. This steel is predominantly supplied in rounds. Excellent both, thanks so sharing.

I was electronic engineering in the ’70s. I’ve started making things recently. This was really good information. Thanks

The more and more I watch great videos such as this really makes me regret not taking up an apprentice ship in machining\engineering. Now at almost I feel a lot of my working life has been a waste. In saying all that I truly hope the remaining years will be so much better in my little work shop just from the pure enjoyment of working with metal.

An impressive man, bearing the full majesty of Fellow of the Institute of Mechanical Engineers. As a mere Member (I've been called this many times), it was very instructive to hear him speak. Materials are an important part of my work in aviation so thank you very much for making this video. Best wishes, Dean in Oxfordshire.

Thanks for introducing us to Richard with his wide experience in materials. In America black mild steel is known as “hot rolled”. I suppose to differentiate it from “cold rolled”.

Thank you, Mr. Crispin, for having Mr. Gibbon and his wisdom in your video. As we say here in the States, every project needs at least one "hairy-eared" engineer on it. The only downside is that now I just have spend the money to get that T-shirt he wore (being hairy-eared myself)!

An excellent video. The comment, “making things is the most wonderful way of spending time” is so true!

Another very informative video for those that are less informed. Here in Australia we have a Boiler Code that we in the Hobby must follow. The Australian Miniature Boiler Safety Commitee or as we know it the A.M.B.S.C. There are 4 codes being Copper, Steel, Duplex and Sub Miniature Boilers. I grew up in the hobby as my Grandfather was heavily involved with it to the extent of being the Technical Representative back in the early 1980's as he was a C Eng, MIE (Aust) for John Lysaght & Australian Iron & Steel. Our code was started in the 1960's to set a standard for the hobby to follow to keep things safe.

Superb, what a great video. Happy to sit and listen to Richard and yourself in conversation anytime you want!!

I love the thought that Richard is going on a boiler maintenance course.

Just visited the Museum last Tuesday, not only are its things a treasure but also the people who curate, restore and maintain those things. Cheers!

Fantastic. Please thank Richard for sharing his knowledge. This was a great interview.

Very good Mr Crispin, everyday is a schoolday, I learned a lot and enjoyed the video :)

Hello Mr. Crispin, It was an interesting video, thank you... Very pleased to hear that you have made a tour of Richard's workshop video. Take care. Paul,,

Hi Mr Crispin Thankyou so much for publishing this and of course all your other videos. They have be invaluable, entertaining and informative. As a fitter machinist (more production maintenance and general machining than full machining) for 30+ years in Western Australia it all started with a mentor name Bob Brown (RIP) who introduced me to model engineering at the age of 12 that started my journey and interest. He started me on a journey to build a "Tich" which I still have the whistle, unfortunately life got in the way and I never completed this. I am however building a Rob Roy and your videos are part of the driving force for this. I live and work in a mining town and the closest model railway is 1200km from me so this is currently a solo project with noone else close by to share advice. That is why your channel is so invaluable. As you discussed in one of your videos things some time get in the way of projects, this I am guilty of this too (Rob Roy was started in 2000) but I always get back to this. Thankyou and keep videos like this being published. It certainly helps. Kind regards Rusty

Great episode. Really interesting. Some fantastic information, what a knowable chap to talk to. Look forward to hopefully more episodes with Richard in.

Great video! I enjoyed sitting with you both and just soaking in the knowledge! Thank you!

Thank you for bringing us Richard's wisdom.

Morning Mr Crispin 🤠 What a fantastic interview & explanation of different metals 🤩

What a delightful gentleman Richard is full of enthusiasm and knowledge and still getting a kick out of making things thanks for putting this together Crispin would like to learn more from you both

Thank you both for taking the time to make such a comprehensive video on materials!

What a fascinating engineer to listen to. Thankyou

Every video is a masterclass. Thanks to you and Richard Gibbon. Cheers !

Mr Crispin's skills know no bounds - what a great interview, keeping the interviewee on track, explaining stuff a knowledgeable subject like Richard may take for granted. Loved the cutaways back to your workshop. The only failing was it was too short! Oh, and chuckled at "drill raad" - at least you resisted "sadder"

What a legend he is. So much experience and skill. I bet some amazing stuff has come out that relatively small workshop. Thanks for sharing!

Great stuff! Love to hear more about this type of subject. Thanks for sharing. Can't wait to get my shop up and running again.

Beautiful job of switching between the interview and a focus video supporting the point. Master class in a technical video production.

loved all the information about what the types of metal is good for, Also Richard is a legend , going on a course at his age to learn more about boilers. Who say's you cant teach an old dog new tricks. Bravo to you Richard.

Very enjoyable Love to see a shop tour of his machines and tools

Thank you Richard and Crispin for this insight into metals. The topic of dezincification was particularly interesting. Also Richard your comment at the end, couldn’t agree with you more, nothing more satisfying than designing, building and using something you have created!

Moustache 4tw. Materials 4tw. Love the interview. The shirt and the correctness. You sir are an excellent example of British politeness. In the best sort of way.

Yes, the properties of metals vary extensively so careful thought is paramount when designing any machine, thank you for clarifying those differences, you have a wealth of knowledge that I very much appreciate,,Rick in Alabama (USA) ,SAYS THIS,,Good on ya.

A true service to humanity, capturing the wisfom of the old(e) masters. Thank you Mr Crispin.

This was just lovely, MrCrispin.

Thanks for this conversation!

Lovely job Gentleman thanks for sharing your knowledge with us.

Thank you for bringing us along to hear from a person with such expertise! I never knew about de-zincification, it has ruined many a day for me. It is so lovely to hear from someone like Richard. Please give him my regards.

Thanks for the video. Lots of important information provided there. Excellent tip about using cast iron for the wheels. Cheers, Aaron.

What a splendid, informative & entertaining interview. You are very lucky Crispin to have such a wonderful mentor & the obvious respect and friendship you both share was a real pleasure to watch!

Thank you for a excellent discussion. I have many years of education and experience with materials and I picked up a few tid bits and remembered a lot of information that I have forgotten over the years.

Thanks for the video, Both you and Richard did a great job with all the information.

Well what a wonderful guy the knowledge that Richard has built up is fascinating, thank you Crispin for introducing him. 👴🏻👍

I enjoy materials science. That was an excellent video. Richard is a highly knowledgeable and accomplished man. You are lucky to count him as a friend and we are blessed to have been afforded a glimpse of his knowledge.

Very interesting conversation for someone without a formal engineering background, I learnt a lot. Thanks to you both.

That was a really great interview. Thank you both for bringing it together

American here - awesome pronunciation of 'drill rod'. You're halfway to a row house in south Boston!.

Wonderfully informative chat. It's great to have the wealth of knowledge from people like Richard recorded in the public domain. For me such content is priceless and is what the internet is all about. Each of us has snippets of knowledge that others may not have come across as we stumble through our lives. So share the gems locked in your head people. Thus ends my rant and I'll put my hobby horse back in the barn. Cheers Eric

Thank you- great information!!! Respect from Texas

I like the lights above your wrenches! 😊

A great video containing exceptional information.

Crispin, this video is excellent. Thanks to both of you for the effort. Being new to the model engineering world, I find I have to guard against believing “facts” from my memory that were placed so long ago I can’t recall the sources. Metallurgy is in particular need of reinforcement, so thanks for that!

What a wealth of information. Thank you from us all

A riveting video. I learned a lot. I'll be sharing it with my technically inclined buddy.

Lovely video and very informative. Your going to treasure this for years to come.

A great insight into what to use and where. A lifetime of knowledge. What an excellent video. Hopefully more interviews with Richard in the future Mr Crispin. Regards Kevin

That was an education! Thank you for passing this on.

Great video and nice to see Richard, looking forward to the next video

My favorite over the pond machinist!

im not a model engineer but found this very interesting thank you both

This was a great video and you have done yet again a great job. I take my hat off to Richard Gibbon for getting in front of the camera and sharing his big pool of Knowledge in steam engine building. This has save me as a potential newbie in doing this hobby from costly material mistakes. Its a real treat to watch you get into the detail on Loco building. It would be great to see Richard again. I looking at building a super simplex 5 inch gauge and what a channel.

Excellent information. Thank you!

Oooh, this is really well edited! I like the little asides on topic!

Great video, makes me realise what a very good apprenticeship I had with the CEGB as we were taught about material properties and were to use them

Great video! I learned a TON! Thanks guys.

Great content! Thank you for pointing out the American jargon for the different materials.

Excellent once again👍

Wow…..fantastic conversation 😎

Very insightful. Thanks Crispin.👌

That was fantastic. Good information. 👍

Love the knowledge you put out it's glad to see you back

Thanks for explaining the names of the metal for us Yanks. Very thorough discussion? It held my interest. Thanks, Mr Crispin.

Thanks Crispin you've inspired me to go down to the work shop and get stuck into the traction engine I've been building for far to long!!

Very useful information on metal on metal working surfaces. Thanks a lot.

Great video, very informative for us novices. Thank you for sharing.

Great masters class Mr. C!

Excellent as usual, this weeks Crispin report is in the can.

Fascinating! thanks for sharing your expertise :)

Thanks Mr C. If I got nothing else out of that discussion the lubrosity of cast iron being used for loco wheels made me chuckle especially when the "experts" at the hobby shops sell them. How insane is that. Thank you and Mr Gibbons for taking the time to put this chat together. Most appreciated. One request. Please get some better microphones for each of you. The level difference between the chat and your personal inserts were very marked. Regards from Canada's banana belt.🤞🇬🇧🤔🕊️🇺🇦🍌🇨🇦👍

@MrCrispin. What a superb video you and Richard put together, Richard has probably forgotten more than many engineers have ever learnt, but willingly shares what he knows and still hankers to learn. If you can get the chance to tie him down again I'm sure there are many subjects you could discuss together. When buying material, particularly from a reputable metal stockist who works with model engineers, it is worth mentioning what you are doing with the material. I did it once when building an old published project, and I had forgotten about dezincification and the dealer pulled me up about it. Also they appreciate cutting lists, can be a pain to put together but it helps them to help you. Look forward to the workshop tour.

Interesting video about different materials for different applications and great listening to Richard. Thanks for making this video mr crispin.

I'm a faithful follower of you great series. This contribution is especially useful because of the valuable information from two so experienced persons.

Hi Chrispin, I found this video very interesting and enjoyed watching the enthusiasm and skill of you both.

Excellent!

Thanks for sharing 👍

being near completion of my first engine (Stuart S50 ) I did make my cross rails from Gauge plate , However the cross head is from the brass supplied with the kit . This has set me to thinking that I now need to remake it from Phosphor bronze . It shall be so having listened to your wise words , Thanks and Cheers Ade.

Very interesting as usual. Thanks.

Could you do a similar film on when to soft solder, when to silver solder, when to braze, when to weld, and so on please? Always been making things, and as Richard says, imagining how to make things. That's one the real skills that's hard to gain and one you will never finish adding to. The more you know the more you can do and work out how to do.

Thanks for making this video. I loved it

JUST THE JOB no better feeling when you make something that works , or taking something that somebody has put in the skip ,and you fix it , excellent video keep on learning

Thanks Mr Crispin - I learnt a couple of things from that.

Excellent video

A lot of good information there, thank you!

Interesting video Crispin.

Interesting meeting Crispin, the final comment was the gold missing from the materials list in the discussion! Interesting American accent by the way, got a laugh from me even if it did not land across the water lol. Cheers, Jon
