Machining Cylinder Heads Part 2

[@devemch7851]

I have the trig discussion with young-bies often. Trig and geometry rules! It is basic to traditional tool and die work. This is another example of powerful it is. That was some incredible milling machine work!

[@TheDaf95xf]

Evening Mr Crispin 🤠 Just parked up for the night so nothing better than one of your superb mathematical videos with fantastic milling 👍🏻 Love watching it but dose make me feel like I should of listen at school 🙄 Cheers Stevie 😎

[@beachcomberbob3496]

Better looking than castings, so worth all of the extra maths and mill work.

[@stephenmetsch6316]

Your vids are clear, complete, educational and humorous, (or what passes for it in your part of the world). I especially like your showing moves in the fresh air and detailed maths with clear diagrams. You are a great teacher.

[@josephmagedanz4070]

Thanks for explaining how you got to your final destination... I wish more KZbinrs would. Looking forward to the next episode.

[@63256325N]

Just brilliant! Truly inspirational. Again, your attention to detail is phenomenal. I look forward to the followup videos. Thank you for sharing.

[@dorsetengineering]

Brilliant video Crispin, really brilliant. Love the camera work and the quality of your machining work. Keep it up

[@OthamJohn]

You and Joe Pie are triangle experts - Life gets easier once you can spot them

[@68sweetnovember]

Excellent in every way. Well done Crispin. Love the FFWD sections of the vid. Thank you.

[@markrainford1219]

Excellent video again Mr C. Nice how you convert all the numbers to "American" for our friends over the pond lol.

[@UnbeltedSundew]

These videos are so good. That locomotive is going to be a masterpiece.

[@ashleyward427]

As always, top notch video. And I remember at school all those years ago, what in God's name would I want Trig for............. I think you just answered that question quite convincingly. Thanks again. look forward to the next video.

[@johndavid3343]

Thanks for doing the math that drives the machining. Very good video!

[@caahacky]

Super presentation Crispin. Thanks.

[@Hvtesla]

A truly impressive piece of machining Sir!

[@johnkinnane547]

G'day Chrispin very interesting video thank you for sharing it you explain what you are doing very well kind regards John

[@lockbuilder]

Another great video. Thanks so much for taking the time to make these!

[@marhue7026]

I have been looking forward to this vid all day man!!! Thank you for all your hard work. Consider me one of your grupies mate.

[@MrCrispinEnterprises]

Thanks.

[@rljzathras]

Another superb job. Really enjoying following your progress.

[@scottgard3278]

Awesome work, I enjoy how you explain all the steps.

[@โนรีคอกเบิร์น]

I was watching this video and my wife was overhearing it. After hearing these comments, she said what are you watching. You have to "Be Quick" and Do it in 1 Continuious Motion" when "Suffering from Chatter" as its always good to "go off at a Tangent" when you "Get your face inline"and "Have a Long Stickout". "

[@MrCrispinEnterprises]

Well hopefully she now understands!

[@JonatanGronoset]

Marvelous, this satisfies the engineering junkie in me...

[@chadgdry3938]

thanks for sharing the math, that was fun to follow along!

[@TheFuneralDirector]

Great video, cant wait for part 3

[@samueltaylor4989]

I was waiting the entire time expecting to see the part twist on fixture while you were cutting it, I’m glad it didn’t but I have to say I was nervous!

[@peterfitzpatrick7032]

The cap head screw looked bigger than the M6 Mr. Crispin stated earlier ( 0:50 )...M10 ? 🤔

[@mrmyford]

very well explained crispin, thanks for the update regards...keith

[@jmanatee]

Excellent job making the part and explaining the math

[@lorenlieder9789]

Good video young man you are a sharp one MrCrispin.

[@bcbloc02]

Very nice rotary table work. Looks like the cylinder cover partially covers the bore of the operating piston, does it need a clearance flat milled for that as well?

[@emmajacobs5575]

Nice explanation of the maths. I'm afraid I've gone lazy nowadays and I just draw it out in CAD if the machinists in work want something like this working out.

[@millomweb]

20:30 I've never heard of sohcahtoa before !

[@daveticehurst4191]

Wow Crispin, another fantastic video, very well described and good sharp photography. Welcome to the 21 st Century with your new DRO, are we going to see it in operation in the next video ? I know you were using it just now, but we could see no numbers. I hope that it is one with a PCD function, will make the hole drilling so much easier and accurate. You certainly lost me with all the Maths you used. You Brother must be a very forgiving person, he helped you out with it, even after you abusing his favorite toothbrush last week.

[@thisnicklldo]

Ah, but he didn't know about the toothbrush because it was returned before he got home. Until the video came out. From now on, Crispin is on his own with his trig.

[@TinkeringJohn]

Mr Crispin said he cut the bristles short on the toothbrush, so his brother could have noticed that something was up with it.

[@McFingal]

I'm really glad you do the math!

[@messenger8279]

Maths :-)

[@tobyw9573]

Good lesson in planning your cuts on paper.

[@davedigs]

fantastic Crispin good explanation on the maths now you'll have to buy your brother a new toothbrush

[@granskare]

I was going to ask about the thing on the wall but you have already answered that :)

[@brianbutler3954]

What is the specification for the cutter that leaves that nice fillet along the bottom as it cuts?

[@MrCrispinEnterprises]

I've heard them called bull nose cutters (as opposed to ball nose)

[@redditroom2981]

Hi, I've been thinking about buying a bench top Milling machine, in your opinion what would be a decent one to consider?

[@warrenmaker798]

Love the math at the end... u lost me at "we need to work out the first angle". LOL. I just draw it up in cad and let that tell me. :) Another great video, thanks

[@80grzybek]

Witam kiedy będzie następny filmik? Czekam z niecierpliwością. Pozdrawiam.

[@jamiebuckley1769]

exelent video i was sorta mind boggled lol thanks for sharing.

[@ChrisB257]

Excellent... great video. Very good explanations. :)

[@carneeki]

Nice application of geometry :)

[@jackasken2605]

When will you make more videos.....can't wait?

[@binks166]

Nice work, and thanks for the math,, harvey from nebraska

[@lineage13]

Jesus christ manual machining looks hard!

[@billelkins994]

I did the math for Pythagoras in 16ths of an inch. 3/4" = 12/16" 5*5+12*12=169 Sqrt(169)=13 Hypotenuse = exactly 13/16" Too perfect. Must have been planned.

[@stumccabe]

Bill Elkins . Definitely. 5,12,13 is a well known Pythagorean Triple, like 3,4,5. The next two in the list are 8,15,17 then 7,24,25. There is an infinite number of them.

[@billelkins994]

@@stumccabe You mean I did not discover the 5,12,13 set! I was vaguely aware of Pythagorean Triples. What I noticed was his decimal calculations were easier in sixteenths. Machinists may write down thousandths of an inch but they still call them by their name when they turn up, half, quarters, eights and sixteenths. (I am not a machinist.) I hope you apprecieate the rapidity of my response compared to yours to me. I waited 4 long years, one of which was 2020.

nice work keep up the good job

[@granskare]

I enjoyed watching (got this channel from my son) but I was baffled all the way :)

[@rogersmart1393]

Crispin, why are they that shape? Does the 'square' part of the boss line up with the passage from the valve to the cylinder?* Did the Edwardian/Victorians overdo the aesthetics or is the rest of it machined down (or originally cast like that) for some other purpose? Rog *Edit; just watched part 3 and no, it doesn't 😀

[@MrCrispinEnterprises]

Hi, no the top of the boss is like that so that another component can be attached to it. Cheers

[@Watchyn_Yarwood]

Excellent!

[@derekblake9385]

Your maths is crazy, so jealous

[@JimmiePorterAtStuartArts]

Rookie question: why no lubricant needed?

[@JimmiePorterAtStuartArts]

Never mind I think I heard you say it's a casting.

[@bazmon]

Brilliant ... love it... :)
