Following the regrind of a 1970's Pratt Burnerd 3 jaw chuck I have released this video to show the manufacture of some simple tooling I designed and made.
Presuming you use an edge finder in the spindle, is it not still impossible to ‘touch off’ if the mill head is tipped over as the edge finder will be at an angle?? 🤔
Yes I should really have said touching on with a cutter which is what I went on to demonstrate. Cheers.
@@MrCrispinEnterprises
Of course! 🤦🏻♂️
Another great video anyway!
The same technique can be used with the part on an angle block without upsetting the tram of the milling head, simple. @@MrCrispinEnterprises
Not that simple as the reference surfaces of the component then end up at an angle!
@@MrCrispinEnterprisesIf the angle block and part are both against solid stops the part can be machined accurately by reversing the part in the vise. The head does not need to be tilted on a symmetrical part like this one.
How the F does this channel not have more subs. This is witty and informative.
TH-cam... its cause if you are not American .. I am subscribed with a bell and constantly get his video notifications late..
@@DawidKellermanMe too....
It's because he does not upload regularly and on a tight schedule.
TH-cam will bury your content in the algorithms.
When the big creators that upload multiple videos a week. Take a few days off or a week of vacation, they lose massive amounts of views.
I completely agree.
@@DawidKellerman . It's top quality content, not popular with the plebian masses . Clamp a kitten to the mill bed and away you go , subs galore.
An excellent and most instructing job, as usual. Please tell Jefferson that "Château l'Angélus" is an excellent choice (@8'51"). Moreover, it is a keeper and it deserves to age in a proper cellar.
Very clever.
Good machining practices.
Well detailed.
Well explained.
Straight to the point.
Good sense of humour:)
Excellent video!!
Thank you for sharing.
GOD BLESS!
Enjoyed watching that Mr Crispin. Fascinating yet again on processes. Good mention for John also. Hope the sherry was at the right temp. Stay well.
That there, is how rolls Royce produced some of the finest engineers in the world thank you mr crispin
Thanks for giving John a shout out. I have watched him for years and have learned so much about steam engines and steam stuff from him. It would be great if your shout puts him over the100,000 sub mark. Thanks MrCrispin....
Yes he's good.
Ah Mr Crispin, right on time.
Didn't know what a jaw dolly was, but I see now that it is something from the movie Tron.
😇
Sundays would not be Sundays without John and his colorful language.
Crispin, you are brilliant. This channel is so enjoyable on so many levels. From Jefferson to your unsurpassed level of detail and precision that, as a mere mechanical engineer (but not machinist, not smart enough) I really appreciate. Your vids make me think, which I love.
Thanks and good to have you watching
Well said!
Thank you Mr. crispin from the states. You sir are a gentleman and craftsman. Our lot in life has much cross pollination as I am a Wadkin fan. The precision and class you bring to this material is quite welcome.
John is a little less polished but quite an asset. He has done much in wadkin restorations.
You need and deserve a boost in viewership. Might I suggest a build series using a steam engine from PM research. A cross pond collaboration with Joe Pie.
Dude your good. Nice to see someone make a part with what they have . Not go out and buy tooling to do the job
I'm pretty sure those jaw dolly things were in the movie "Tron".
Another excellent video Mr Crispin. A very clear explanation on how you plan to machine the part. Also an easy to understand demo on using the spindle square. I'd love one of these, as I always find this a difficult job. Cheers Nobby
Another excellent video to add to the store house of knowledge that you populate and curate. Straightforward explanations backed up by clear demonstrations. Your teaching skill is second only to your engineering prowess. I am glad you are on our side.
Good to have you watching.
I love this series. I always enjoy your videos. Thanks
Simply superb. Thanks, Crispin 👍
Great stuff. Always a pleasure to watch you work. That was very nice of you giving John Mills a little boost.😊
I have him two in the same video so it's actually a double boost!
Love the fact that John Mills sounds like he is from a foreign country from you. LOL Rolls must be paying well to have your own wait staff. 🙂 Looking forward to some more work on the little loco.
I had a worn 5" Burnerd three jaw chuck to improve so first machined a ring at the size I wanted to run true. Clamped the ring and "bumped" each jaw to settle them, then with a carbide tipped boring bar through the ring, bored out the jaws, which were not that hard. Then clamped a piece of solid bar at the bored size inside the chuck, bumped the jaws to settle them then bored the front portion of the jaws to blend in, not having either a tool post grinder or surface grinder as you do. Only thing I would do differently in the future would be to machine a very slight reverse taper like say 0.1 degrees on the chuck jaws as the chuck jaws tend to flex outwards due to the clamping force on the workpiece. For parts like your chuck dollies I would use a slitting saw in the vertical Mill.
Another informative and witty machining video. And I have some questions:
1. What was the resulting concentricity of the chuck after grinding?
2. Is Jefferson for hire?
3. Does your brother's smile have that sensual soluble oil appearance?
Brother Billy is still trying to work out why his new tooth paste tastes funny and as for Jefferson his duties as House Steward at Crispin House keep him far too busy to contemplate hire work but I'll let him know!
As for grinding results have a look at the end of the video called 'Re-Grinding a Chuck'
Great video. My only puzzle or question is that the clamping surfaces of the jaws are now curved at the diameter ground and if clamping on larger material the outside edges will be gripping the material and could mark it the material (vice versa for smaller diameter) is this intended?
Yes that's exactly right and something I've thought about myself. That tends to be how chuck are even from new. I guess the alternative would involve having to grind them away from the chuck and then it becomes hard to get everything on centre.
If the jaws are ground at a fairly large diameter (2-2.5 inches) the curvature will not matter as much.
Another exceptionally clever and accurately crafted solution from MrCrispinEnterprises. How many machine shops have enough class to sport a "Gentlemans gentleman" on the payroll - lol
Excellent work as usual. I never expected your ring to be so rusty but I guess for the job at hand a rusty ring is perfectly acceptable, and not uncommon.
Nice to see a rather technical piece of fixture making and the final result. Thanks for the video Mr Crispin.👍👍
Love the into good sir. However it appears that you may have uploaded this video a bit late. I’ve already purchased a rather expensive dovetail cutter as you hadn’t informed me of this sharing angles approach sooner.
It couldn’t possibly be my fault for not thinking of this myself..
Of course I am only poking fun, but why on earth I didn’t think of this is rather humbling.
Thanks for sharing your process.
Always enjoy your content.
Yes it's a good technique to be aware of!
Very good, sir. A marvelous channel.
Great presentation. 5:00 Sherry sounds nice indeed!
Perhaps a silly question (I’m an amateur), but how accurate is the ring on which these pins compress, and how might that affect the trueness of the ground jaws at that particular opening?
Hi, as long as the ring can to best fit it's self between the three dowels then it's fine. The concentricity of the ring doesn't have any impact on the grinding operation.
Have a look at that machine, it’s dripping milk all over your work piece I don’t know if you noticed
Excellent job, Mr. Crispin. Lots of good ideas. Thanks for showing.
Excellent video as always, that's the best jaw regrind I have seen, thanks for sharing, Coventry 🇬🇧.
Thanks
Excellent video as usual, I always look forward to Mr C.'s excellent output.
really enjoyed that...made super special by spotting your box of our local Saint Emilion wine. good choice for a 5pm swifty. Simon in SW France.
I can't remember where that box came from but it looks a bit expensive for my taste!!
Great video as usual Mr Crispin, thank you.
I was just thinking about checking to see if you had any new videos out as I hadn't seen one in a while. I have been surprised that your fellow Brits John as well as Ade haven't gotten more subscribers. I think I was first directed to your channel in 2016 because of your locomotive build videos.
Have you seen Stefan's Pacman oblique corner finding thing, similar to tooling balls
Yes I believe it's an example of a 'Tool makers square'
Отличная работа! Интересный способ!!! Как говорят, old school is best!!!
How are you getting on with the FP1 ?
Could you perhaps consider a video of your experience with it please?
Yes it's a great machine
Many thanks for the shoutout to John's channel. For a mechanic that just pisses about in his garage, he's done well. His content is varied and always interesting.
I simply had to watch the first part twice🤣....Twastard...."common engineering terms"🤣🤣
Excelent video. A great method for jaws rectificarion. Thank you for transmit your knowledge
What kind of vertical milling machine is that? It looks like the perfect size for a serious hobbyist. GREAT content, by the way!!!!
Thanks and yes it's a great machine. It's a 1965 Deckel FP1
This is an excellent way of working. I cheer for you. ❤❤❤❤❤🎉🎉🎉🎉🎉
You are a voice of sanity in an insane world.
Brilliant! As soon as you said flip it on it's head I said "dovetails?!" Your a mad genius 😊
Excellent! Love the interruptions for when the sun is over the yardarm.
Subscribed to your channel on the advice of our mutual friend Mr Mills. Very informative and enjoyable if I may say so. Thankyou
Great show. Now I think I’ll go watch a James Bond (Sean Connery, of course) movie. After Doubleboost that is.
As always, it's great to see new content. I'll have to go back to the grinding video and re-watch that. I really need to make a set of these. As always, thanks for sharing.
yer bell is a bit loud. It made mi jump😁. great video, good of you for giving John a mention, He's been hovering below 100k for ages, He deserves a fancy button, hopefully with your kind push he may finally get one.
Very good info, I have a tool post grinder and manual surface grinder that I have little knowledge of truing the wheels for different Jobs. Keep up the good work including grinding jobs.
You and John should do a joint video, that would be interesting.
Mr. Crispin, thank you for entertaining us once again. Just some feedback on your videos - What would be interesting is how long you spend from start to finish on a part or parts. Cheers Andrew
very nice and clever as always. do you have a video abort the deckel fp1? I just got one and have many questions 😁👍
No buts something I could do
If the chuck jaws are the bolted on type you can machine three bolts with extra long heads to serve as clamping studs.
What happened to the steam engine??
Not allot!
You'll need subtitles on John's channel, though...
Thanks for this video.
I have just learned heaps in a mere 24 minutes!
Such drama, intrigue, and in the end, the agent got the girls, uh dollies.
Love watching Mr Crispin Makes me wish I had got a good education and be able to do that kind of work fantstick
Make a loco !!!!!!!! n
I suspect that if your brother cottons on, he is going to do something very nasty to one or possibly even two of your cups of tea.
you are the most 65 years old sounding 26 year old i have ever heard in my life, in a good way I mean
Nice to see how you went about making those, many hours of work on just 3 parts there.
Smart boy! Very well done!
AvE led me to John already :)
Great channel!
Where can I buy a Jefferson? I also want one.😅
I need to work on getting a butler for my shop.
Hey, nice seeing you. Like Halleys Comet
I hope your job is safe, good luck
Can I borrow your butler for a few months ?
Your brother is so generous to lend you his toothbrush!
I don't recall a mention that the brother had been consulted... ?
Oh my Mr Crispin quick grab your cap put it back on your head and think FLY CUTTER for the 30^
Can't stand fly cutting other than for flat surfaces!
Are you going to every work on your train again
I recognise that silver platter upon which the mug was served as the missing YAA u16 gents recurve champion trophy. Can I claim my reward...?
Unfortunately I had to buy it on eBay!
You were born 100 years too late. You clearly have the work ethic and skills of the greatest generation. The music and old machines adds to the vibe.
Good point. However, every generation develops its own skills, not necessarily the same as the previous.
Brilliant work, thank you! 👍
That John is a good bloke.
Very good job my friend 🇧🇷🇧🇷🇧🇷
Reverse threaded screws on the right hand side of the headstock? That's interesting!
Don't think they are reversed? Sometimes you get funny effects on camera.
I'm new to the channel. Any chance of a workshop/toolbox tour?
Yes it's definitely on the cards at some point
Jolly good. Excellent parts. Nice technique.
thank you!!!! hope you still find time to play guitar
Indeed!!
Nice to see you back, looking forward to train build soon? 😉
Yes indeed
I think you mean Doubleboost not Doubleboots in the text Crispin. I met John at the Hunton Steam Gathering back in September, managed to have quick chat.
Rizla have a new paper out called Rizla Precision, I measured it at 0.02mm thick when I bought a pack for use on the mill.
Hi Mr C, "sherry o'clock", bring it on. Looking forward to your next appearance.
Always interesting and joyful. TKS.
Great job clever idea . With a addition of three small jaws that would fit in the dowel holes you could hole thin round stock . Now if one wanted to open up a washer its a pain to square it up . I might have to make some. JM
I’ve been a doubleboost subscriber this past age. Thanks for the mention!
I need a Jefferson, you are so blessed to have a personal valet that will prepare your tools 🤣 Nice example of sharing an angle sir. Outstanding work.
Great video -- like the parallel squaring fixture you shows briefly. Do you have any info on it or can you go into some detail on it in a future video . Would make a great project for a tool box addition. Thank you for the great content, and chuckles (look forward to the hat throw on every video). PS; Thanks for plugging Doubleboost - he has a great channel as well.
Thanks. Have a look at Z squares made by Bar Z industrial
Thank you for the lead. Think I have a G Job coming up in my future @@MrCrispinEnterprises
You literally have a Bridgeport with a shaper/slotting head.
Missed opportunity to use it.
I just recently made a 1-3/16" by internal hex coupler for an earth auger.
Rarely does anyone use such a great tool these days.
Good for a hex but a very slow way of removing material.
@MrCrispinEnterprises It is definitely a slow method. But, it's effective. Unfortunately you rarely see anyone who has one using it.
And even more rare is the tooling. It's about as extinct as the Dodo bird.
I have to make my own tooling. And that's often slower than the job itself.
Brilliant Thanks
Jefferson could possibly ask one of the estates carpenters to make you a bespoke stool to aid you in your deburring tasks. I feel sure that your future self will thank you for taking good care of your back.
Great Idea. I like it.
Wooster and Jeeves :)
What's your favorite test indicator?
The Mitutoyo 2 micron one is my favourite I think.
Amazing finish from the Surfacer. Luster abound.
Nice small mill....
This might be a silly question.. but would it be stupid to make the Jaw dollies using 3d printing?
I cant imagine they need much force when tightened down? and they are only likely only to be used once.
interested in anyones thoughts..
Perhaps you could 3d print yes but you don't want anything giving during the process. A reasonable amount of force is required to make all three jaws bed down and interact with the scroll as they would in normal production.
@@MrCrispinEnterprises thanks for taking the time to respond
@@MrCrispinEnterprises considering they only take 15 min to print. Will give it a go on the Colchester and report back :)
