That's a nice little kit, very well documented. Those little side bits of information are a always a nice bonus.
Enjoying the build...
Cheers...
Thanks Dean . Cheers 👍
Waffle on Max! Whatever you have to impart is worth listening to mate!
I couldn’t agree more 👍 ….. Waffle on Max. I have so much to learn. 😊
No worries 👍
G'day Max, happy days mate. I've been looking at these myself, and I might go for it after seeing you make it look so easy. Them tapping do da things are hard to identity eh lol, Happy days, and thanks for sharing
No worries . You just can not thread up to a shoulder , they make special stepped dies for that purpose . Cheers 👍
Looking forward to the next video. Hope you are getting a bit of the rain that's moving over at the moment. Was looking a bit dry there.
Lol , it's been raining pretty good for the last 2 days off & on . At last , but now i am over it !!! Cheers 👍
As I watch these videos, I am always thinking about how I would make the whatevers and in this case we had similar approaches. It was gratifying to know that I was thinking along the same lines as someone who knows what they are doing. Cheers.
No worries . Hey , that small carbide drill you sent was a God send the other day . I had to dimple a hardened shaft for a lock screw ! Thanks . 👍
Max, great start to your DIY "Kant-Twist" Clamps & don't be concerned about waffle, it's good info.
As an old Jeweller, we used the same JM "Easyflo" flux & would add in a few drops of dishwashing liquid into the jar, to help it break surface tension & capillary into the joint better.
Thanks . I did not realise dishwashing liquid would do that . Cheers 👍
"Tapping thing" is indeed the right name of the tool, I think...
And I hear nothing but positive comments on these clamps, so I suppose they're really good.
I wonder if they are as good as your ''Made In Germany Clamps '' ! Cheers 👍
@@swanvalleymachineshop Time will tell.
Thanks, buddy, another really entertaining video. I would have used a form tool on the knobs to give a more rounded end but that's just me.
No worries 👍
Max you’re quickly becoming one of my favorite online machinists. I don’t know if it’s the interesting projects or the way you approach them but it’s entertaining to watch. Cheers from Phoenix Arizona, USA
Thanks 👍
Silver Steel in the UK as well Max.
Thanks 👍
Keep on with the waffling and the anecdotes! I was hoping to hear more about the parting incident in 1980.🙂 Neat trick on brazing the bar ends on - certainly never thought to do that. Cheers!
Thanks 👍
All our spring centers have that inverted cone on other side, just pull grub screw out and turn them around, not sure on the brand we have but not near as much play as yours had, we actually keep one with inverted cone stuck out and other one with the pointy tip stuck out to make it simple 😉
The other end of this one is flat and hardened ! Cheers 👍
I made the clamps to, I order only the laser cut legs with the drawings and bolts. Futher you can use material you have leing around so as most of us have. I make 4 and they are working very well. I can recommand them to you all. For the long treaded part I used stainles treaded rod M10x1,5 that works very well.
I may have looked at making my own but these came along . The other thing , i was not sure about the pivot ratio as not having one to look at . Cheers 👍
looks like a cool kit to learn some skills on, when you were doing the parting I was on the edge of my seat ha-ha, looked like you were setting it up at 80 before you moved it closer to the chuck and went 85. definitely good call not to drill right through really wouldn't look anywhere as good as the cups with solder. these will probably be the most accurately built clamps ever. will have to see what freight from Canada is like.
Thanks . I have been meaning to swing past . 👍
Great job on the clamps Max...That's the proper soft quiet flame for silver braz'n, I can tell you've done a lot of it!
Cheers 👍
You have good, and expensive tastes when it comes to keyless chucks!
Lol , that one popped up on E Bay ages ago for the right price ! They are good chucks ! Cheers 👍
Morning Max from UK, nice start to the week. Have been looking at making a pair of these clamps so will, follow yours with interest
No worries 👍
Excellent video! I look forward to seeing your videos every week.
Thanks 👍
Good show, enjoyed it, thanks Max
Cheers 👍
very good video friend Max..thanks for your time
Cheers 👍
Great video. I learned a lot. I'm not a machinist, but this is interesting. And the part about the tap holder thing, I loved it. "What the f**k is this thing." Great. Shows someone real, not playing to the camera. Can't wait till the next one. Don't worry about the time. You keep things interesting.
Thanks 👍
Nice project building those clamps. I am ordering some for myself. Thanks for sharing.
No worries 👍
Yes, we've all been put on notice for using tee type tap handles with a tap follower! A lot of my taps don't have either a male or female conical centre which makes it even harder to follow best practice. That Coventry die head is a nice piece of kit. I stupidly passed up on the opportunity to "stocktake" one from a capstan lathe that came into our possession many years ago.
Regards, Preso
Lol , JP is correct in what he said on his video but sometimes we just have to use what is at hand ! I could not pass these did heads up when they came along , i used to use them a lot back in the 80's & 90's so i knew how useful they can be . Cheers 👍
G’Day Max, I don’t recall seeing this type of clamp in videos from Oz. They’re as common as drills in the States, where they’re called “Kant Twist” clamps. Marvelous things, offered in a heap of graduated sizes. 👍
You are right , i think they are not a common thing here . I have always used & seen the common toolmakers parallel clamps . Cheers 👍
Thanks Max. That die head sure works a treat. Nice work with the camera, cheers.
No worries 👍
I really liked your mod to the spring loaded follower. I am going to steal that.
Lol , Cheers 👍
I'm fairly new to your channel here in the Eastern United States and love your channel, I really enjoy the longer videos and diversity of work, keep making chips mate, and thank you for these excellent videos!
No worries , Thanks 👍
Such a great channel. Good for a chuckle, too many lessons to count. Top shelf.
Thanks 👍
Over here the tap thingy is called a 'Pump Centre'. Not sure why, it doesn't pump anything, that's just what they're called. Maybe it looks similar to a plunger pump when being stroked? Ken
Lol , that sounds like the name of a ''Knock Shop '' Cheers Ken 👍👍👍
Thank you Max!
Cheers 👍
Was wondering how you got your depth on the drilling, very clever! Will use that idea for sure
Thanks . It is close enough for most jobs when drilling . 👍
I love those coventry die heads. I think ill have to get some. cheers Max
They are worth their weight in gold ! Cheers 👍
G'day Max, Thanks for the reply to my question regarding parting "upside down" in the last vidio. And I appreciate you showing the parting blades you use here. cheers, Butch.
No worries . I will touch on the parting tool in a future video . Look at one of my older video's . ruclips.net/video/LkfoNgaMDX0/видео.html 👍
I hate the term "Tap follower" for some strange reason, I prefer "Sprung Centre", but horse's for course's as its said.
Nice work Max as always.
Thanks for sharing.
Tap thing ! Cheers 👍
those clamps are realy handy, thanks for sharing max.
cheers
ben.
No worries 👍
G'Day Max Cant twist Clamps are a Bobby Dazluh and a joy forever in the shop. Cheers Mate
Cheers 👍👍😎👍👍
No worries 👍
Hi Max The taping head works really good. Cheers
No worries 👍
I see you are using Anchor Lube. Did you get that from Stan over at BarZ or was that something you found locally in Aus.?
Yes . Bruce Witham bought some back from his Bar Z visit a few years back . I have just kept it aside for special jobs but have been using it a lot lately . 👍
That threading gizmo is scookem! I think down there it’s referred to as “ fair dincum”? ( that makes spell check nuts! ) What an asset. I’ll never have one, but you scored with the set. Do you set a stop in set up? Looks almost automatic in use.
I use the lathe carriage as the stop . Cheers 👍
Ha Max if you undo the hex set screw from the tap follower I think you will find that the other end is a reverse cone I checked mine and it is reversable will wonders never cease.
I did . The other end is flat & hardened ! 👍
G'day Max. Excellent work, Still very impressed with your tapping jig. Everything just seemed to fall into place, wondered where the time went
Well done, & very Professional
Cheers Ted . 👍
WAffle on as much as you like mate. I'm loving it!
No worries 👍
G'day Max, perfect timing to catch up on a new project 👍.
Edit:
Made me chuckle when you stopped to explain the tap follower cone Vs point before the keyboard warriors started after watching Joe Pie
Lol . Yes , i made sure i got in first ! If your tap holder is straight , it will still cut a true thread . Tapping heads hold taps all piss wobbly & the tap squares itself up . 👍
Wonderfully instructive as always. Thank you. Why do you prefer turning with the coarse carriage rack wheel, rather than the graduated compound?
Habit . And the compound is not always set dead straight , only eyeballed to the zero degree graduation . 👍
I must have been lucky with the one I go off eBay as I said it has a point and a cone.
I must have been stitched up like a kipper , the picture only showed the pointed end ! 👍
Those Coventry thread cutters take 5 seconds but are over$1000 to purchase. Still always like someone who shows how obviously is enjoying the process. Silver soldering & that green flame ain't known commodities.
Cheers 👍
Thanks Max!
from east Tennessee
Cheers 👍
great work thanks for the video
Cheers 👍
Up to your armpits in projects as usual eh Max. 👍
Was wondering what the hold up was with the JFMT lathe. Will be interesting to see what’s been going on.
These clamps look like a fun project & handy tools to have once your done.
As I I don’t (yet) have silver soldering capability, could I not just thread and tap the slides & brass cups & loctite them on maybe? 🤷♂️
Will have to go look up the kits and see what they cost.
Keep up the good work, will be looking forward to the next instalment.
👍👍👍🇦🇺.
Cheers Ian . Turn a step on each end of the rod & the caps can be drilled through & peened over . 👍
Thx for the vid.
Cheers 👍
I've seen other machinists have a different angle on the parting tool. It leaves no nub on the desired side, looks like 10-15 degrees.
It does have that angle , it is ok for steel but needs to be a bit more severe for brass as the fatter end of the tit was breaking off before the small end . Watch when the tool first contacts the brass . Cheers 👍
I've got threading die envy Max...that thing is cooler than penguin shit!
Lol , Cheers 👍
Thanks for sharing 👍
No worries 👍
Hi Max, I use Iscar tooling and parting tools.
I also have a Kennametal parting tool and in my opinion cuts marginally better than the Iscar parting tool.
Where do you purchase silver steel, I get mine from Radio Spares Philippines , shipped ex UK.
Is there a supplier in Perth?
The silver steel was an assortment i found on E Bay a few years back . Can not remember where it came from . I have not looked for a supplier here yet . I think the Kennametal blades use the same or similar insert as the older Iscar ones before the Tang Grip came out . I don't think they can take as much curry as the Tang Grip . Don't ask me how i found that out ! Cheers 👍
i would not have silver soldered (brazed) the cups on to the rods. There will never be any longitudinal force, so I would have just drilled for an interference fit and heated them to get them on. Simpler to do and gives a better appearance without needing buffing.
Shouldn't the screw be given an Acme thread or buttress thread?
A V form thread is pretty standard with small clamps .
Hey Max, Question for you. Would you recommend doing an oil hardening process after making the threaded parts? Or are they strong enough?
I would not worry as that steel will not oil harden & i feel it does not need to be hard . The 12L14 steel has to go through a carburizing process or similar to increase the carbon content to harden . Also you would not want the top where the cross hole is hard . 👍
G'day, Max.
I'm surprised as a machinist that you didn't already have a set of those machinist clamps in your arsenal.
I'm 63 and still use the set I made when I was an apprentice. They were the third tool we were instructed to make in year two. What tools did you make?
See you in part two cobber. 👍🏴⚒️
I have always only used toolmakers parallel clamps . We made callipers , drill angle gauges , vee blocks , parallel strips & reamers etc . Cheers 👍
Max is slipping! Ref 11:39 - for a few seconds it looked like he was going to wind in the micrometer correctly, with the rachet/clutch knob, and not the thimble like he always does.
Lol , i like that !
Good evening from the true down under across the ditch, called kiwi land.
Cheers 👍
👍
Cheers 👍👍👍
What is the least smelly drilling-tapping paste you can think of? :)
Anchor lube ! 👍
@@swanvalleymachineshop How does it smell? Like thick machine oil or more like some smell-good hand cleaning paste? :) Asking for my home workshop. Literally, in the apartment.
@@Tome4kkkk You might be better off with oil . Soluble oil , but use it with out adding water . I use it that way a lot . Castrol MB50 is the one i use but i do not think you can get it in small quantities & it's expensive .
@@swanvalleymachineshop Thanks for all the information. I'm going to try to get the anchor lube through a foreign contact.
That kit in the US is 375 AUD!
Wow ! I better not stuff it up ! Cheers 👍
@@swanvalleymachineshop I was talking about the cut off tool and insert kit not the clamps.
@duanedickey7043 wow , they have gone up in price !
21:56 - I think the word you're looking for is Dimple
Lol , that's it !!! Cheers 👍
Tap follower
That's the one ! 👍
Your "matter of fact"way speaks years of precision. Thanks for your time and skills!
Cheers 👍
