In this video I show a method for drilling compound angles. The machine is a Deckel FP1 and the component is a cylinder block for my 5" steam locomotive. (Springbok)
A sophisticated solution to a none existent problem. The drainhole doesn't need to be exactly in the bottom of the cylinder,the water will drain perfectly well from a slightly offset hole,it doesn't mind. However, it's great to see a properly trained and competent tradesmen at work ,thank you.
...way back in the day (pre-CAD) I used to teach A level 'Mechanical and Geometrical Drawing' ...when covering this sort of stuff used to get all the kids to proclaim 'Lines in Space!' at the start of the lesson - a la the opening credits of 'Lost in Space!' TV programme (showing my age) ... they used to love it ... Ah, the good old days:)
I am one of the three people! I trained as a toolmaker at the RAE (demolished, thanks very much Thatcher) and have a life long interest on steam power, especially loco's I'm very glad you are back so I can continue to follow your progress. Your skills are more polished than mine, I moved to the drawing office as soon as my apprenticeship ended.
0:15 You are not a beginner! 😉 You may not have drilled those particular holes before but I guess that you have done similar work quite a few times in the past. Very well explained and filmed. Excellent! thanks.
If you're a beginner then I'm the neanderthal yet to discover metal! Excellent videos, clear detailed and an inspiration to us lesser beings. Thank you for sharing your time on here.
This takes me back to my tool and die advanced trig compound angle class back in the 70's. You've done a fine job of explaining along with your pictorials.
Thank you Mr Crispin. Yet another very clear presentation. I very much enjoy your videos. Your extremely knowledgeable and you get the method across perfectly.
Crispin sir you dont do yourself justice, you are highly skilled at your craft. If you fear not many people watching its only because they are some of the only ones smart enough to grasp the principles and math. I would say you could take that as a high compliment-!
great job, well done. thanks for sharing. I'm French, I don't always understand everything but the video editing helps a lot, as well as the diagrams. Thanks see you soon
There are quite a few machining channels if this sort of thing tickles your fancy. I can suggest you look in on Blondihacks and Joe pieczynski for educationally inclined machining videos.
I recently discovered Mark Presling too. He has a Stuart #8 build, made a Victoria era styled iron bridge and an amazing restoration of a Bridgeport mill. And don’t forget Andrew Whale (LearningTurningMetal).
Well done! Very clear in your delivery and explanation of the steps along the way. I'm an engineer and that kind of geometry can be daunting to keep straight. The fact that you created views as needs for each new plane is spot on. Looking forward to more videos now that your new shop is up and going. Thanks!
What I like about your videos MrCrispin in addition to your skill and craftsmanship is your ability to clearly describe the complex into simple segments that are easy understand for those of us such as myself that struggle with mathematics, and geometry. How I ever became a machinist and mechanic amidst that struggle with these subjects I will never know. But alas,somehow I get by. Cheers
I absolutely love your channel. You articulate your ideas and methods in such a clear and concise manner. Absolute joy to watch. Bloody well done mate. Keep going please!
This was very good practical demonstration put in a straightforward and unassuming manner. I can remember a maths lecturer in a HTC course demonstrating a solution to compound angled flats for milling. It was like a Bach fugue - he unpacked algebra all over a blackboard and resolved all the expanded equations into a single expression, substituted in two drawing dimensions and carried out a single division sum in a calculator for the answer. It took 3/4 hour, it was beautiful, but by the end I was admiring the elegance of it more than I was understanding the process. This demo, however, took me with it logically as well as aesthetically. Well done.
I am so glad you're making videos again. As a total amateur I appreciate learning practical applications of geometry and you are an excellent teacher in that respect.
This was an incredible summary and detailed explanation. Definitely watched every second of this action packed video. Thank you for taking the time to detail this for us. Joel......
I made it though! Really makes you appreciate what’s going on when you just plop down a new work-plane in 5axis CAM and the machine sorts it out for you.
you a beginner. yer right! i'm 55 with a crappy little lathe, trying to build stationary steam engines. It's watching people like you who gives people like me ,the inspiration and knowledge/know how of how to do, and achieve things. keep up the good work.
Just watched your video, and it brought it all back to me. I used to be in the hydrolic business, drilling valve blocks that had check valves. This included a lot of double compound cross drilling. Using a radial arm I used to tilt the work rather than the machine. I found getting tooling to reach or get into the valve cavity the hardest problem. But you explained it well and I enjoyed watching the video.
I have a couple of lathes and a drill press and work mostly making parts for my old motorbikes, but I just have to admire your ability to think your way out of problems like these, sure it's all been done lots before, but your understanding of the maths and equations is an eye opener for me. Looking forward to the pistons and rods work etc.
LILY. "Yes I know 2 weeks in and you are continuing to find Drilling holes videos on RU-vid!!" Well as I build 5 inch gauge Model locomotives it is part of the Hobby. Thank you again Mr Crispin. David and Lily.
Nice Job . I love that you took the time to explain the theories behind the set up you were doing. This was my first video of yours that I have ran across. You can believe that I am now a subscriber, and can not wait tell I have time to view some more of your content. Thanks for sharing.
If 3 has watched this to the end, at least now there are 4. Yet I must say I find general relativity (think of Einstein) somewhat difficult mathematically but my head hurts after all this geometry. Well done.
Excellent video ! I had forgotten about using tooling balls and along with buttons i think these are things that a lot of hobby machinist would have never seen used . That Deckel looks like a very nice bit of kit ! Keep safe and i eagerly await your next video !
Exemplary explanation and demonstration, I think the method you used is the simplest, in regard to not having a compound head, and maintaining the part orientated in X &Y. Very impressive layout, and good use on the "Hicky Ball" ( that's what I was taught to call the Tooling Ball in the Black Country, not sure if other regions used this name). During my early apprentice days, I had to form compound angular faces of location blocks using a compound vice on a shaper, and as you explained, setting double angles gets very confusing. Thanks for sharing and stay safe all.
I remember learning about skewed lines in space in a mechanical drawing class about 50 years ago. So far I am drawing only blanks coming up with anything useful on the topic, LOL.
Very interesting well presented topic. I would like to know more about the applications that require such an angled hole and for what purpose it serves.? Perhaps there may be a simpler method of design to achieve the desired objective. Would appreciate your response, considering most home workshops may have only basic facilities. However thanks for your excellent video which I viewed from start to finish. ☑️👍
@@MrCrispinEnterprises Hi, and thank you for your quick response. I checked out the video as you suggested and I can now see the reason for the angled hole for your application. I watched the whole thing and enjoyed your excellent presentation. Thanks again for your prompt attention to my querie. You may find my website an interesting distraction which is an example of concept design to realisation, further explained in my introduction and marketing videos.

Hello Mr. Crispin, I am writing to thank you for producing your excellent RU-vid videos which I thoroughly enjoy. I like the way you combine the math with the actual machining. If you have time to reply, could you tell me what the bore size is on the locomotive cylinder. As I follow along with your calculations and wanted to determine the final angle in your video called drilling compound angles. Where you used a tooling ball! This brought back memories for me when I was a young man working at Rolls Royce in Barnoldswick, in what was then Yorkshire. I worked on the grinding section, mainly on fixtures for turbine blade production, but that was over fifty years ago! We used tooling balls all the time. Well, keep up the good work as I am still learning and fully appreciate your efforts. All the best, Jack Firth, Canmore, Alberta, Canada.
