Instagram: mr_crispin In this video I machine a clamping sleeve to hold an automatic die head on a Myford Tailstock. The machines used are a Harrison 190 and a Deckel FP1.
Wonderful to see someone use a spot drill for when a spot drill is suppose to be used. Most self proclaimed machinist tend to use a center drill for that.
Greetings from Austin Texas USA Crispin. Thanks for the mention and nice job on the adapter. Before I go, I have to say you must have a guardian angel to get so lucky to have the die head and tailstock be so close in diameter. Check that off the list. It will never happen again. Stay well.
Thanks Joe. That is a very handy technique you showed the the overcoming of chatter. Very handy for all those with bench top machines as well as chatter is a common issue. Cheers.
the phasing of the lathe chuck with the lights and/or the camera shutter is fantastically cool! the proof is not in the pudding, the proof OF the pudding is in THE EATING (i know this because i eat pudding!). excellent video - thank you!
Dear Mr Crispin, I'm working my way through your videos, and would like to say thank you for making such entertaining and educational content. Great job, very much appreciated. I found your interviews rather interesting.
I like this channel! Been having a binge. Quite a project getting the shop set up, all right. The background music is really good, although quite horrible - but my ears aren't broken half a second after it starts - 10 points!! When I found this vid my thought was how come this old coot hasn't got grey hair like me? Turns out he's not old like me. BUT! You've got the dust coat and the hat, do your top button up, get a tie, get a scribe and a ruler for your top pocket, and lastly a clipboard with the day's project on it. For such a young old coot you make nice stuff! I'm subbing.
Thank you Crispin for a very interesting video. The clamp looked to be well thought out and expertly made, despite the issue with your chuck. Hope it’s relatively easy to resolve. 👏👏👍😀
Very interesting, thanks Mr Crispin. I can see I am going to have to watch your entire back catalogue of videos. Loved the humourous bits as much as the informative bits. 😁👍
Time was in short supply so I apologize for rushing through this video. I just wanted to comment that I really liked your setup on the milling machine. Whenever I see a horizontal from a time not so close to this I think I kinda what one myself. My age is such that I remember when this is what was the most common type on the floor and they are too this day extremely versatile and very capable machine tools. I like your shop thank you for taking the time creating the content. Bravo
Great video, Crispin! I always like to see when my favorite RU-vid machinists show their errors (it’s WHY they’re my favorites). By all means, make sure to video how you fix the chuck issue, we’d love to see it. The mustache bit was great, but please: if you are at any time planning to undergo a circumcision, feel free to do that off-camera. 🤣
As you started machining, my mind was going through the ops. Right after facing, I said, "now center drill, bore, and insert center". I always do those ops first and use a center. Especially, when the stick-out is 3x the diameter.
Many machining videos hide the audio of the work being done. I think is adds to the 'machining experience' we non-machinists can only imagine. For this reason, along with the musical accompaniments and seven years of videos I will watch to possibly see you smile/laugh, I'm now a subscriber.
What a well thought out approach that yielded a result that did not require altering either the tooling or the tool. Well done and keep up the good work!
Morning Mr Crispin 🤠 from sunny Spain 🇪🇸 I do like watching your videos as they’re full of humour with some very good technical information and work thrown in 😆I’m no engineer but do like watching how things are made and problems solved 👍🏻
I guess we are all guilty of making tools for our tools so we can make tools, eventual outcome is a shop full of tools. Love it, can't have too many tools.
Hi Crispin, nice design and well executed. Good detective work on the chuck grip, the joys of filming your own work, you get to retrospectively see stuff you would never notice in the heat of battle! Cheers, Jon
I enjoyed the detective work. You can only check so many things when you are overhauling. The rest reveal themselves and you just sort them out. I guess the level of checking and testing depends on what you working with and what level of disaster follows failure or how expensive.
I like that Mr C. I mounted my Geometric head on a taper shank, then drilled and taped a hole for a grub screw underneath and through the tale stock quill (where you cannot see it!) to lock the whole assembly in the quill to keep it from pulling out of the taper. It works.
Great video Mr C, I will never be a machinist but love to watch how you make these things, your hands looked scarily close to that chuck when you were using the scotchbrite to my non trained eye, glad to see it was only your moustache that you lost, can't wait to see you sort out the chuck and carry on with the locomotive build thank you
Hello there Mr. Crispin, greetings from Minnesota, USA. I just recently discovered your channel, I've been enjoying your videos. Nice and lighthearted, modest and informative. Particularly enjoyed watching this one and the rationales and process. All the best and stay well.
I had the same problem on my 10" p&b 3 jaw at work. I bought another as you know... its work. 🤣 Look forward to seeing your solution it might become more useful than a door stop!
Hello Mr. Crispin, Enjoyable viewing, thank you. On the video about correcting the jaws it would be great if you could also include a small section on how to establish if you have the problem, that way us viewers can perform the check. Thank you in advance and see you on the next one. Take care. Paul,,
Butting here, in my case i had trouble parting in the 3 jaw but not the same job in the 4 jaw. "Thinks" thought I. Turned out the 3 jaw had bell mouth, an easy fix to bore using titanium carbide boring bar. Ps the chuck is a good oldcfashioned Pratt Burnerd and yes you can turn them, you dont need to grind.
As always first class sir , also must comment on the most excellent musical soundtrack … seems to machine so much better with this particular accompaniment ! Awaiting your three jaw Chuck solution as I have one here doing the same as yours ! Regards Partsmade
I thought the part moved before you locked the saddle, it appeared to jump a little giving the impression of loose headstock bearings. Nice to see the Myford getting some love... 👍👍👍
It is interesting that you have a lathe and milling machine to make parts for your lathe and milling machine. I just finished watching Rotary SMP's latest video, where he said he has a basement full of machine tools to make parts for his basement full of machine tools.
Isn't that why we're all in this hobby? "He who has the most unfinished projects when he died wins"! UFP's my wife called her needlework unfinished projects and boy did she leave a sewing room full. My shop will be just as bad.
Why do I have a lathe and a milling machine? My answer is that the lathe make parts for the milling and the mill makes parts for the lathe. 🤣 Drives the wife crazy!
Even your mistakes end up as masterpieces. The whole lathe being a machine to make parts for a mill and vice versa is something I hsve only recently realised.
nice vid mrcrispin, 1 point to adress, i would made a key on the clamp for the tailstock, because the cuttingforces are very high and you would not want that clamp spinning on your tailstock spindel, that would be the end of your tailstock accuratie...
"A cosmetic and geometric cleanup operation" My math teacher hinted at those kind of operations, without really clearing them up. And you just show how its done. I'm flabbergasted.
Nice part. I had a chuck like that with "bell mouth" jaws. It's an easy fix if you have a toolpost grinder. But as the saying goes, you can't teach your granny how to lay eggs. Or something like that. 👍
I did like the stache and sorry to see it leave so abruptly. I have an Atlas 12 x 36 lathe with very little wear or use and it's chuck was terrible to use and material would tend to walk out of it. If you put in a longer shaft you could grab the end and move it back and forth a bit and I could slip a small feeler guage under one jaw. The slots the jaws went into were very tight and the jaws had matching numbers. The one jaw when you put a straight edge on it had a notable crown in the middle and would rock back and forth. Another jaw stuck out further than the other two as I put a boring bar inside and turned by hand it would touch with lots of space from the other jaws. The remaining jaw was sticking out more on one end than the other end. I made a holder for a dremel and opened the jaws and spun the chuck and ground the jaws. They were something to see after but made a world of difference. The chuck is made in England is very narrow and the material is held close to the spindle. I had taken the chuck apart and checked everything and all was good and seemed to have been built very well and everything was tight. I like the chuck and pleased with it now. The runout improved tremendously as well. Dale in Canada 🇨🇦
The better finish with the heavier cut is to do with heat, you can improve the surface finish on lighter cuts by increasing the surface speed if you have higher gears available.
Make a bed stop for the tailstock to come up against for repeat operations with a Coventry diehead... I have a lineshaft driven turret lathe amongst my collection of antique machine tools... Herbert No.4......an early one from around WW1 🇬🇧😐
Good evening Mr Crispin, Delighted to see you back ! My Coventry die head floats in a socket with a No.2 morse taper shank to fit the lathe tailstock. A slot machined along the length of the socket, and a close fitting modified socket head screw fitted into the slot and a tapped hole in the shank of the die head allows it to float axially, whilst restrained from rotation. This allows you to lock the tailstock up solid and to do repetitive screw threads to a set length very quickly. I make no claim for originality - it was given to me by a retired tool maker nearly 40 years back, but I offer it as an alternative solution - I think that the die head has to float freely up to an axial stop to trip the die head, and open it up at the end of the thread, and I’m not sure how you will achieve that yet, with your arrangement. If you have a moment or two, can you elaborate please ? Kind regards, Steve A.
The tailstock will be pulled along by the threads and when it comes in to contact with the locked carriage it will cause the die head to open. Interesting to hear about your design
@@MrCrispinEnterprises Thank you for that - I’d forgotten the stop that you fitted to the base of the tailstock - it all makes sense now ! Kind regards, Steve A.
Thanks for showing this. I love Your videos. Apart from the causes already revealed, in my opinion the rpm for grooving and parting off was way too high. I always use my lowest gear.
WHEEEE. Crispin in action at last. Great without the upper lip hair again. Glad to see the new lathe in action. Did you sort out the inverter to get a better ramp up and down time, looked better to me than your last video for stop and start times. Regards from Australia.
You look younger without the caterpillar. Or as our American friends like to call it, the cookie duster! 😊 In the meantime can you not pack the chuck and wrap parts with paper until you get round to sorting it? Look forward as always to your future project MrCrispin.
Excellent, and very impressed by the choreography but why when you fed a sheet of Boccherini into the lathe did it play an Eric Coates composition? (I think it was Coates)
