Every time I see one of your videos I realize you served a great apprenticeship! Such attention to detail, i.e the paper etc, etc Rolls Royce!!! Mine was a little more humble British Leyland, but what a great preparation to all the jobs I eventually successfully got!!
"wire wool" or "steel wol" is a poor choice for polishing aluminum since the fibers can become lodged in the softer aluminum and rust later on. "Scotchbrite"(a polymeric material) is preferred. Many thanks for a fine video.
You certainly got a super grind on the trepanning tool - nice result. Certainly faster than boring from get go. Your usual fine attention to detail. Most enjoyable. Your cylinders are beautiful.
I’ve always used brown paper for adding friction. I read somewhere that typical brown paper bags have clay in them which increases the friction coefficient.
Your work is outstanding and you explain the things your are doing very well. Many people have said you would make an excellent instructor and I couldn't agree more. Thanks for sharing, much appreciated.
Another great video Crispin, well done. Now a short note for our World viewers. Crispin mentioned that he was using Paraffin as a lubricant when machining aluminium, this is a UK / England term. The rest of the World will know it as Kerosene.
Stop misleading people, WD 40 is NOT Kerosene, it is a specially formulated WATER DISPERSANT liquid really meant for starting old style cars that have a distributor. Yes I have seen it widely used by other UA-cam contributors as a cutting fluid especially by the Yanks. But its main use is for dispersing water, it can be used when fitting a taper chuck to a lathe, under a machine vice etc, to help prevent moisture and rust forming.
Dave Ticehurst Jeez dude, leave your sense of irony in bed today? BTW, as a former professional mechanic, I can say to never use WD40 as a rust preventative. You will be fine putting it under a vise or on a lathe taper, but once the aromatics in it are gone it will actually attract moisture. It is a first class cutting lube on aluminum, a decent penetrating oil, a hard to beat moisture displacer (as you stated), but it is a terrible rust inhibitor.
Pmailkeey, that's a false claim! Unless I'm doing allot of turning I just put 1/8th" oil in the bottom of the oiler. I always forget to switch them off and if you have filled it right up it runs out everywhere.
@@ShevillMathers I think it was a little larger than the 7. I also think it had a 2 speed pulley on the motor as well as the three speed on the transfer shaft & spindle - giving 6 speeds. The 7 was just a 3 speed (not including back gears). The threading gearbox I think was the norm on the super but an option for the 7 and I think the super had power crossfeed. I think there were more 7s sold than supers.
@@MrCrispinEnterprises I don't think we once forgot to turn them off :) I also don't remember ours being more than half empty ! It happens though - you can forget to do something. Put a sign inside the workshop door saying 'have you turned the oilers off? as a reminder for when you leave !
Yay! It's like a late Christmas gift when you put up a video. Got to finish making coffee and settle in :-) What will I learn today? Really, you should be an instructor.
From wikipedia: "Trepanning, also known as trepanation, trephination, trephining or making a burr hole (the verb trepan derives via Old French via Medieval Latin from the Greek noun of relevant meaning trypanon, literally "borer, auger")." Mostly done to human skulls they stated.
Hello crispin lovely trapanning tool I have a 6 inch one (carbide insert) they are very useful when going large diameter wholes in thin work and they save material . I like too your starrett uni micrometer sadly I couldn't find one so I made in with a Moore and wright head . I also made a spherical anvil micrometer . There great for internal taper measurement . Thanks for another Brilliant video!!
Nice technique for thin walled parts, could even go much thinner that way, one thing I would do differently, is use something else than steel wool to polish the Al part, you may find little inclusions of steel into the caps and eventually rust will show up... ;)
Lovely how well it went together, always feels great when the fit is perfect. I often find it strange how the decorative parts are often what determines how much we like something, but it has always been so. Will the securing screw be a hex head or do you have some other design? It looked bigger than 8 ba, but it's hard to judge sizes on videos.
Miss the clutch on the Myford, P.I.T.A the stop-start on so many lathes including the imported ones I now have for my telescopes/ observatories building. 👍🤗🇬🇧🇦🇺
I have noticed, that all the noise the microphone picks up, .... your lathe is one quiet machine... what have you done to make your lathe so quiet? or maybe, the microphone simply doesn't pick up the noise?... either way, fine job, as always
Hi, Smoothness of operation is one of the characteristics of a Myford. Its very small and not designed for big loads but it is very quiet and it runs smoothly. Cheers
No trepanning was performed in this video ! MrCrispin has merely turned a groove in the face of the work. Trepanning is the action of removing a piece. Had the groove been deep enough to go right through, then the centre boss would have been trepanned out.
my son John who is a computer guy put me on to you. I have almost no idea what you are doing but I have a question. do you work in the aviation division of RR? thanks, chuck
that will be an exciting field...there was this Qantas 380 that had a problem with one engine..Luckily it was not far from Singapore and it got in safely...turns one small thing was bored a bit off center. This was the first using the new engine....did not do RR much good so don't allow some guy to say that's good enough...Best wishes and best of luck..chuck
I think you might be able to mill out a miniature liquid fuel/LOX rocket engine that actially could work, your skills are out of this world. The magic metal to mill is titanium.
Lieber Mr. Crispin, so jung, aber ich kann mit meinen 72 Jahren von Dir viel lernen. Danke.
Thanks
Sir, you're not a machinist - but an Artist! Fantastic work.
Every time I see one of your videos I realize you served a great apprenticeship! Such attention to detail, i.e the paper etc, etc Rolls Royce!!! Mine was a little more humble British Leyland, but what a great preparation to all the jobs I eventually successfully got!!
great work Crispin nice to see another appearance of your brothers toothbrush hope you put it back without him knowing all the best for 2017

Another interesting video Crispin. Can't wait to see the assembly and finished loco. Thanks for taking the time to do the videos :-)
Once again a very great video as well as great craftmanship. Hoping the next video really soon!
Once again excellent fit and finish work-! Youre apprenticeship at R/R is well deserved. Great video, interesting turning method.
I oftentimes use emory paper to get a really strong friction drive, it is a good technique.
Nice to see a Yorkshire machinist and a Myford lathe, miss the one I had when lived in Leeds. 👍🔭🇬🇧🇦🇺
Can't say I miss the ML7 - I think the Student was a good upgrade. This one seems to purr along nicely despite no oil in the oilers ;)
@@millomweb Mine was a Super 7 designation, maybe there are some differences between models.

Good to see you again. Thanks for the video.
Nicely done Mr.C.!

I say Crispin! Nice video on technique and work holding. I always enjoy your videos, Happy new Year! And thank you.
13:28 It looks like the cap will interfere with whatever caps off the spool valve ends. Is that so?
Yes indeed
@@MrCrispinEnterprises Ok. Looking forward to seeing the final assembly and especially the first running!
Thank you!!!
Thank you for video and knowledge share! :)

Thanks. Yes good point about the steel wool. Thanks for watching.
11:33 Wot, no revolving centre ?
If may ask, how did you become interested in machining?
Good stuff Mr Crispin :)

@@MrCrispinEnterprises Not an Allen screw ?
Very good!
Miss the clutch on the Myford, P.I.T.A the stop-start on so many lathes including the imported ones I now have for my telescopes/ observatories building. 👍🤗🇬🇧🇦🇺
We didn't have a clutch on our ML7. But we do on the Student !
@@millomweb I had one on the ML Super 7
@@ShevillMathers Again, a standard item IIRC. Noting that MrCrispin has one on his ML7. Not a standard item on those, so most didn't have them.

Hi, Smoothness of operation is one of the characteristics of a Myford. Its very small and not designed for big loads but it is very quiet and it runs smoothly. Cheers
I am curious: Couldn't you have used the side of the tool after the first plunge? I am no machinist, so sorry if the question is too obvious.
Hi, Yes you could, although I would still have to do multiple cuts to remove the stock so its down to personal preference. Cheers
Most interesting. Thank you.
Great video, thanks you!
Nice Mr.Crispin
“Aluminium and steel? It’s going to corrode horribly!” … oh. I have watched too many boatbuilding channels today 😂
Great video! I was thinking that an alternative to trepanning on the lathe would be to use a rotary table on a milling machine. Thoughts?
Thanks. It would be possible to do it on a rotary table however I think it would be slower and in this case quite difficult to hold the work. Cheers
@@MrCrispinEnterprises It seems an odd suggestion considering it's typical lathe-work.
No trepanning was performed in this video !
MrCrispin has merely turned a groove in the face of the work.
Trepanning is the action of removing a piece. Had the groove been deep enough to go right through, then the centre boss would have been trepanned out.
Hi, just a quick question , what diamiter are the finished wheels ? that is if this is a 5 inch B1. thanks , joe
Hi, 6.250" is the diameter of the running section. 6.562" to the outside of the flanges.
MrCrispin thankyou :) my lathe is too small haha
my son John who is a computer guy put me on to you. I have almost no idea what you are doing but I have a question. do you work in the aviation division of RR? thanks, chuck

MrCrispin Just like to say very nice workmanship, however those covers serve the purpose of insulating the cylinder covers.

so you are not Crispin - why did you make an answer?
I think, to do the other side, I'd have used jaws internally on the i/d gently.
I think you might be able to mill out a miniature liquid fuel/LOX rocket engine that actially could work, your skills are out of this world. The magic metal to mill is titanium.
What's magic about titanium ? My brother's got some. Maybe I'll ask the undertaker to give it back !
2:46 There are? disappointing 'levels' of oil in your two spindle bearing oilers !
carbide inserts like big loads, to get chips
heavy cuts'
Yes, Unfortunately my little lathe and fixturing doesn't!
MrCrispin true enough. love ur vids and skills man.
Thanks
MrCrispin no prob bro!
High pitch noise is driving me nuts.
1:45 MIND THE TIT! :-)
