Machining Cylinders Part 7

[@andli461]

That “exit predictor” must be one of the most clever and at the same time simple tool ever. 😳 Can’t understand how it has taken until now to find this channel. 🙈 The good thing is that am in the very beginning of my binge watching and it’s a lot of exiting episodes left. 😃

[@MrShobar]

I'd bet that you still took a deep breath when you first touched the tool to the cylinder. Excellent work and discussion, my friend.

[@MrLukealbanese]

Excellent work Crispin, glad to see that Rolls Royce still employ the very best people!!!

[@dlstanf2]

What a complicated piece of work, and, at the end of much work on the cylinder. Great job. I've enjoyed this series and the amount of detail that most people never see.

[@shawnlund]

Brilliant video, my favourite one so far as I slowly work through the lot of them. The setup for that slot was a rathe complicated bit of work and watching someone else do it was a real treat 🙂

[@WHJeffB]

That tooling ball trick is fantastic!!! I have to remember that one! Another great video Mr. Crispin, thanks for sharing with us.

[@KimbrellBrad]

You and your peers are some really great machinists! That cut would have scared me to death! Wrong place, milled wrong, bad finish, tons of things could go wrong LOL. Great demonstration and explanation! Will have to watch again to catch more of it!

[@rupertpowell]

I bumped in to Tony Simons yesterday and he was singing your praises. This video just goes to prove what a talented engineer you are.. I also found out we both went to Fulford school. Great video Crispin...looking forward to the next one.

[@ShevillMathers]

I make things in my workshop, telescopes and cameras etc. but these model railways engineers are a breed apart from us mere mortals. I have known a few in my long life and I am always so impressed with their meticulous attention to detail, fit and finish. Watching this series beats watching TV any day. Thanks so much for sharing and I have subscribed to see how it all goes along.

[@ronwalsh]

Recently found your channel, and I am glad that I did. I was taught machining before there were anything like CNC, and we were taught to use the tooling balls. It has been many years since I had to do math like you are doing, but at least I am able to follow what you are doing. I must say that your skill with the machines is second to none.

[@MrCrispinEnterprises]

Thanks

[@tuffymartinez]

Thank You MrCrispin !!!...I am a late bloomer to your video's...slowly catching up...This one in particular I will be watching several times to get my head around it...Jeff

[@juanrivero8]

Well done. Took some math(s), but that is why you learn it. That "position predictor" is a jewel.

[@jimmilne19]

Learned a lot, saw some artful machining and was uplifted by your spirit. Thanks for sharing. Cool video!

[@wallacesaan]

Thanks very much for showing the use of a tooling ball. I have seen these in catalogs, but did not know exactly how they were used. Your explanation was excellent!

[@HaraldFinster]

So much thought and effort for a "simple" slot - fascinating. Thank you very much for giving insight into your work. It can't be easy to do this complex work and film in parallel.

[@joell439]

Outstanding craftsmanship. Your videos are so fun and exciting to watch. Well done!

[@ChrisB257]

Quite a challenge setting up... nicely done. As often the case, set-up time is the a major part of a whole operation. The math takes perfect sense.

[@edwardsides4152]

Brilliant set of videos. Takes the viewer through every step. Well done.

[@MrCrispinEnterprises]

Thanks. Im just building a new workshop at the moment but looking forward to doing more videos.

[@rljzathras]

Absolutely brilliant description of the setup and operations required.

[@daveticehurst4191]

Another great tutorial in your machining cylinder series. Certainly a lot of math and careful setup needed for this delicate operation. I hope the other 3 slots came out OK. Keep up your excellent work and interesting videos.

[@thecorbies2521]

Hi Mr Crispin. Beautifully done. You are a credit to engineering. Regards Mark in the UK

[@engineeringmodeller]

Just like to say thank you for all these videos. They are some of the best I have seen on machining and your explanations are so clear. I am embarking on the construction of a Sterling Single and these have helped tremendously.

[@MrCrispinEnterprises]

Thanks Very much. If you need any info on the Stirling single I may be able to help as a friend on mine has built 3 of them.

[@steamsearcher]

Superb? Yes, I have done the whole 7 tonight and am totally inspired to do some built up ones for various projects!! We are based close to the Reading Track!!! Thank you ever so much!!!

[@MSmifffy]

Great video. When I machined the ports on my Royal Scot, I played around with angles but to nowhere near the level of detail you have here. Ultimately, I ended up working by eye and nerve wracking as it was, it worked. I do like the destination tool you showed, that would have taken a load of stress away 🤣

[@howardstandring5530]

Excellent explanation, really interesting and provides an in depth hands on lesson, for all who want to develop their own model engineering skills.

[@josephmagedanz4070]

Thanks for the video and making a complicated step understandable (there are real-world applications for maths!). Looking forward to the next video. Thanks again. Joe

[@GandyDancerProductions]

Nice work, well done. Building a steam engine to a high standard is a lot of work. I've do it myself.

[@ralphbarnes2994]

very good, easy to follow, great teacher. really like your description for all your settings. Way to go.

[@robgerrits4097]

Very detailed, nice to watch, thanks for sharing it.

[@lorenlieder9789]

Very nice work young man.

[@bulletproofpepper2]

Yes, yes that is great and I understand. Have to take some aspirins, hit the rewind few times. So awesome. Some times in life, it's not that you know all the answers but you know where to find all the answers. Thanks very much for sharing.

[@RobB_VK6ES]

Impressive work and some interesting solutions. I have been a machinist for nearly 40 years and I am not too proud to admit I learned a trick or two along the way in this series. You have gained a subscriber. Everyone knows about Pythagoras' Theorom h²=x²+y² but not everyone knows it also works for 3D h²=x²+y²+z²

[@raoulcruz4404]

I watch several video channels with content such as yours. Most machinists would simply put a digital protractor on the piece to index it. I appreciate your method of using the sine bar. That’s a technique that could be lost over time. Also, using mathematics to locate the cutting tool, instead of a digital x,y,z table (something I’ll never be able to afford). Quite intriguing.

[@MrCrispinEnterprises]

Yes a sine bar is the traditional way to do it

[@devemch7851]

Classic! I love your round ram! True tool and die is about the math. Tooling balls and note plugs are an easy way to get accuracy. Sine bars are a cheap way to get very high angle accuracy. I am restoring 3 Wadkin machines from England. Wadkin went to rolls Royce and said he will build machines like they build cars. He did! The myford lathe is simply one of the best designs in its class. I don’t have a CNC but I have a round ram and my wood lathe is a 1943 Wadkin RU. Wouldn’t change anything. At work, it’s a different story. Love your videos and talent. How about a shop your?

[@328DaveGTS]

So great to see your back . Great Video thank you again .

[@Bayhunter2011]

Excellent tutorial as usual, thanks for sharing, look forward to next video

[@darynradcliffe2909]

splendid job Mr Crispin, very clear and understandable explanation :-)

[@fpreston9527]

it's amazing what gets made in drafty sheds in the bottom of peoples gardens !

[@joepie221]

Nice job MrCrispin. I've always had a working respect for compound angles, and have had many conversations / arguments with the engineers that define them. Angles do strange things when you start introducing the second angle. The tooling ball is a great thing to keep in your toolbox and fully understand. I have several. Nice work.

[@MrCrispinEnterprises]

Yes, Luckily in this operation although the slot was at a compound angle the tooling ball wasn't. it was inline with the zy plane of the machine so it made the maths straight forward.

[@ashleyward427]

As always. beautiful work.

[@Marzy5821]

Stella work Crispin well done!

[@MrCrispinEnterprises]

Thanks

[@pmaci56]

the part at the end showing the slot ending toward the cylinder cover and a chamfer being removed from the cover is similar to what i found on a 1875 3'6" gauge locomotive when i was cosmetically restoring it. It had a history of being called astmatic and it had been improved at a workshop later that year the rear cylinder cover had a 4" wide 1/2"deep slot hand chiseled from the port that was covered over by the cover when it was fitted

[@brosselot1]

great work. very precision job.

[@TomChame]

Beautiful work!!!!!

[@a6cjn]

Superb!Very well done!

[@bcbloc02]

I wonder if in the days of old they would have machined those passages or just made them into the castings and run them as cast.

[@KnolltopFarms]

Either way seems like a tricky proposition, at least in my mind. How would you suppose they cast internal passages like that? I'm sure the cast-masters had their methods, and knew which parts to cast and what had to be machined. It's all just incredibly fascinating to me. I'm so glad MrCrispin has begun filming again, and he's even inspired me to get back to shooting things...now let's just see if I can edit things, LOL!

[@bcbloc02]

Knolltop Farms Editing, is easy, cut, paste, post. That is how I do it. :-)

[@MyHeap]

The position predictor! Ingenious! Cool example with the tooling ball. Care to show how you made it? (The tooling ball) Joe

[@bazmon]

Very, very nice work Mr. Crispin... :)

[@68sweetnovember]

Truly wonderful. Excellent.

[@irish-simon]

great video very well explained

[@mastermat630]

wow xD so precise in your job !

[@mog5858]

great stuff keep up the good work

[@stephenreeves9025]

"position predictor" I've used the spindle end of that, wish I would have thought of the other half of it though, would have made a difference in a few of my guess-o-mates.

[@cadser0engco]

Great stuff.

[@doriancharles608]

another great video

[@chadgdry3938]

that was pretty cool...

[@phooesnax]

Impressive!

[@darwintheory1535]

Would a horizontal mounted dividing head help with the angle issue? Love the video!

[@aymanMOHAMED-xz8oh]

How to make Exhost valves

[@onlygazza]

Brilliant 👍

[@tunnel7]

Mr Crispin if this was 5yrs ago where is this Loco ??? searched and searched but cannot find any recent Videos of it so where is it please????

[@MrCrispinEnterprises]

There are more loco videos since then but by and large I have not been working on this project.

[@tunnel7]

Well thanks for your swift reply I was a Manual/CNC Turner in the Aerospace industry for many years and RR for a while, would have loved to have taken on the challenge of building a Locomotive at some stage but now I potter in my shed with wood. Good luck in all you do Mr Crispin love the vids just not enough of them, you need to get out of that industry while your still young.

[@JoshKilen]

nice job

[@ElTelBaby]

@ 9:24 ROFL No Dad;... it is NOT a model Tea Pot Lid...

[@63256325N]

Brilliant! Thanks.

[@sadeghpouryan5049]

good job

[@lockbuilder]

Outstanding. I love the way you worked through that. where do you live? I'm not used to accents like yours using inches! I'm always expecting metric. Very well done sir!

[@michaelfiller3452]

Just now finding this vid, good job, good explanation of the trig. How is your shop rebuild coming along?

[@granskare]

may I ask your age when you began machining? we have never done this sort of work...thanks:)

[@georgebuzea9831]

Great job MrCrispin! Were can I send you an stp. project that might be of interest to you?

[@ybaggi]

I love your build. At what presssure are you going to run this? and what power will one of these cylinder produce at that pressure? Are there anz engineering reasons for milling the cylinder rounds (like heat distribution) or is it purely esthetic? cheers

[@Keith_Ward]

Who of you were helping him blow off the cast iron dust? Btw, great work Mr Crispin!

[@georgemoore2704]

Love the vids but I am just curious to know why you run such a high speed on the milling machine? I always run a slower speed with hss tools

[@shawnlund]

George Moore 2000 rpm is right about in the ballpark for an 1/8th “ 2 flute cutter in cast iron. I tend to stay on the conservative sides of things as well myself. But these smart fellows have speed and feed calculators installed directly into their brains. They get installed at the same time the trigonometry module and patience of a saint programs go in.

[@totorina2722]

Whaoooo !! Respect

[@jacobrush1184]

Awesome work as always! Great idea with the button. Do you think that little area of cylinder liner will be ok? Visible at 17:34
