A bit of waffling, a groove, and a bit more waffling... Useful circlip information, this site is really useful : roymech.org/Useful_Tables/Cir... See you soon, Ade
If the professional does not have creative intelligence, having the most sophisticated instruments will be of no use. I was able to observe the references taken using the base of the machine tools to define the beginning, end, spacing, determining with precision each intelligent stage of the work itself. The recovery of the crankshaft, damaged by some mechanic or technician "boar" was difficult, but with totally positive results and still improved. Too bad there is no international school for learning industrial mechanics. You would certainly be the Technical Director and advisor from the beginning until the end of a technical course of thousands of hours of classes at an international level. A true doctorate in metallurgy and industrial mechanics.
Thanks for the mention Ade, there is always another bit of kit we need! The project is going really well, circlip fitted a treat. As my brother said, we grew up being taught about British bikes by our Grandad. I've had a lot of Japanese bikes but now I also have a little Francis Barnett to restore once the workshop at my new house is sorted. Thanks for telling us all about the mill, my brother and I had wondered about the make. Really enjoying the videos, many thanks. Dean in Oxfordshire.
I would have liked a Bridgeport but they are a lot taller with the motor on top, mine is like a pillar drill with the motor at the back so it fits in the workshop well. Must get my power feeds finished though...
That worked out well.👍 Cutting that groove reminded of a job i had once where i had to do the same on a 4 cylinder bike engine while still in the frame. The clutch pushrod seal failed and the way you are meant to do it is split the crankcase halfs, a non starter price wise, so i made a little "boring head" which piloted on the pushrod bearing and used a cordless drill to remove the seal retaining ridge and then cut a circlip groove. Saved the man a fortune, which he didn't have anyway.
That was very interesting. Great to hear you name check Dean from Oxfordshire. He's my brother and he enjoys watching you a lot. Our Grandad died in 1996 and he was a huge inspiration on both of us in terms of our engineering interests. He had several classic British bikes over the years and would have loved all this, and the fact that my brother and I now both have home machine shops. My copy of Machinery Handbook is from 1950 and doesn't even mention circlips or retaining rings! I looked up yours in my Newnes Mechanical Engineers Handbook so I could follow what you were saying. Thanks again.
Thanks for the back story, interesting stuff, great that you both do the engineering and follow the channel. You've got me looking at other books now, retaining rings are in my 22nd edition (1987) machinery's, page 1038, but not in my 9th edition (1937),nor are they in my Caxton engineering workshop data, (1947), maybe circlips are more 'modern' than I realised. Then thinking about it, I've worked on some 1930s engines and the gudgeon pin was clamped in the con rod by a bolt and the bushes were in the piston.
@@AGEngineering Hello and thanks for the interesting reply. I have lots of engineering reference books and I always find it pays to consult more than one source of information. I have the Caxton Millwright and Maintenance Engineers Handbook series which are highly informative too. Our Grandfather was and is a pivotal figure in our lives. My brother and I have been steeped in engineering from a young age and we both ended up being Royal Air Force Aircraft Engineers.
Great work that tool was not shabby, I did see the threads near to the grove but on camera it looked 4mm away! It worked well & I think you did right thing, a little lock tight in the grove in case it starts vibrating round but I very much doubt it. A little information on your mill motor while doing a slow cutting part was very clever got me interested. I Like the mission so far & reading the comments you have got your audience hooked 😀 it was nice to get a mention ’ but I think you had it all covered!! you don't miss a trick. You've forgotten more than I will ever know. Rob
I like how when you improvise using what you have when you don't have what you need to get the same result.That takes years of experience and ability to think outside the box.Thats what seperates the boys from the men.lol...
I think you'll find that the word "circlip" is a trade name, they were originally made by a company called Seeger, hence the generic name of snap ring or retaining ring.
hello, I need the clutch cover for my BSA Rocket 3 A75, #19-7801 or 57-3705, can you supply it? what's the price? can new or used; do you know who can sell it? . THANK YOU
