Machining a Set of Jaw Dollies 

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?? 🤔

How the F does this channel not have more subs. This is witty and informative.

Sundays would not be Sundays without John and his colorful language.

Ah Mr Crispin, right on time.

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....

That there, is how rolls Royce produced some of the finest engineers in the world thank you mr crispin

This is an excellent way of working. I cheer for you. ❤❤❤❤❤🎉🎉🎉🎉🎉

Love watching Mr Crispin Makes me wish I had got a good education and be able to do that kind of work fantstick

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.

Didn't know what a jaw dolly was, but I see now that it is something from the movie Tron. 😇

Thanks for this video. I have just learned heaps in a mere 24 minutes!

Smart boy! Very well done!

You are a voice of sanity in an insane world.

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.

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

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.

Excelent video. A great method for jaws rectificarion. Thank you for transmit your knowledge

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!

I love this series. I always enjoy your videos. Thanks

Great Idea. I like it.

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.

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

Excellent job, Mr. Crispin. Lots of good ideas. Thanks for showing.

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.

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.

Brilliant Thanks

Simply superb. Thanks, Crispin 👍

Excellent! Love the interruptions for when the sun is over the yardarm.

Very good, sir. A marvelous channel.

That John is a good bloke.

Brilliant! As soon as you said flip it on it's head I said "dovetails?!" Your a mad genius 😊

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.

Excellent!

Your brother is so generous to lend you his toothbrush!

Excellent video as usual, I always look forward to Mr C.'s excellent output.

Отличная работа! Интересный способ!!! Как говорят, old school is best!!!

Nice work sir!

Excellent video as always, that's the best jaw regrind I have seen, thanks for sharing, Coventry 🇬🇧.

Great stuff. Always a pleasure to watch you work. That was very nice of you giving John Mills a little boost.😊

Subscribed to your channel on the advice of our mutual friend Mr Mills. Very informative and enjoyable if I may say so. Thankyou

Nice to see a rather technical piece of fixture making and the final result. Thanks for the video Mr Crispin.👍👍

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

Hey, nice seeing you. Like Halleys Comet

If the chuck jaws are the bolted on type you can machine three bolts with extra long heads to serve as clamping studs.

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.

Great video as usual Mr Crispin, thank you.

I’ve been a doubleboost subscriber this past age. Thanks for the mention!

Nice small mill....

AvE led me to John already :) Great channel!

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.

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.

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.

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.

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.

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.

Always a pleasure to watch your channel. 👏

Such drama, intrigue, and in the end, the agent got the girls, uh dollies.

Amazing finish from the Surfacer. Luster abound.

Good evening Mr Crispin 🤠 Love watching your videos 👍🏻

The opening is so funny love it

Always a pleasure to watch a new video on your channel.

Always interesting and joyful. TKS.

Hi Mr C, "sherry o'clock", bring it on. Looking forward to your next appearance.

Another great job Mr. Crispin. 👍👍👍👍👍👍👍

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.

Brilliant work, thank you! 👍

On word, “quality”. 👏👏👍😎

I hope your job is safe, good luck

Great show. Now I think I’ll go watch a James Bond (Sean Connery, of course) movie. After Doubleboost that is.

Jollie good work Crispin, keep it up.

Jolly good. Excellent parts. Nice technique.

I'm pretty sure those jaw dolly things were in the movie "Tron".

Nice to see how you went about making those, many hours of work on just 3 parts there.

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.

I need to work on getting a butler for my shop.

Interesting machining operations.

Great I learned a lot watching you work....

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.

A very interesting video. Thank you 👍🙂

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?

I believe I need a butler as well.. Great video as always!

great as always!!

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

Dude your good. Nice to see someone make a part with what they have . Not go out and buy tooling to do the job

Very good job my friend 🇧🇷🇧🇷🇧🇷

Reverse threaded screws on the right hand side of the headstock? That's interesting!

Excellent video!

As one great professor used to say 'Most satisfactory'.

Excellent video

Nice to see you back, looking forward to train build soon? 😉

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.

Have you seen Stefan's Pacman oblique corner finding thing, similar to tooling balls

Reminds me of the alien spaceships in the old space invaders arcade game 🕹

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.

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?

Poor Jefferson got a lot of coolant to clean up after you, as well as a 🪥. 👍🏴󠁧󠁢󠁳󠁣󠁴󠁿

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?

What kind of vertical milling machine is that? It looks like the perfect size for a serious hobbyist. GREAT content, by the way!!!!

You'll need subtitles on John's channel, though...

Wooster and Jeeves :)
