Of all the damned things I never knew how to do, and you lay it out in the first five minutes as if I *should've* known this from childhood. Well-done , JC.
Always an education, thanks, John! As a senior high school student many, many moons ago, my Technical Drawing teacher would pull his hair out because I'd finished the work so far ahead of my classmates. The upshot was, while my mates still progressed through the normal curriculum, I was invited to pull a piece of gash machinery out of the cupboard and retro-draw the piece into a new drawing. Ever since I've loved the complexity behind the design of tools and machines. Downside, I hate working with the bloody things! Never been much for getting my hands actually dirty! LOL
Well done John. Accurate and useful. The taper inserted into the Jacobs chuck is, funny enough, called a Jacobs taper (JT) and there are 7 or 8 sizes to suit ever bigger chucks! The workshop series is a keeper, imho.
I love your car content, but I have to say that I am really enjoying your tool and DIY videos. I do a lot of work around the house and yard and sadly lack a fat-cave space now, but will look into that in the future. I learn something new all of the time in your content, and I am that much closer to not blowing myself up or creating a wormhole in my closet.
Great vid JC. It's probably worth mentioning that cheaper and less precision chucks might hold larger bits but not smaller drill bits of 1.5mm and under. 13mm chucks on battery drills usually hold 2-13mm bits and 10mm maximum chucks will often be effective down to 1mm or 0.5mm. I worked in powertool repair for a couple of years and chuck replacement was a common task for tradies ( usually in a hurry) manufacturers who used Locktight did not make the process easier. Cheers Paul.
I recently learned firsthand how difficult it can be to extract an arbor from a chuck. I got it apart using the first-party Jacobs wedges, but the required force to unseat a JT33 is unbelievable! Loved the video, didn’t seem long at all.
Really good to see I'm not the only one who secretly raids the kitchen of various items and then denies all knowledge. Muffin trays are really good for small parts organising when disassembling machinery.
could one theoretically magnetize the bottom of each of the muffin bits of the tray so the bits tend to be drawn to and held inside the concave sections? :p
Amazing, I just took delivery today of a drill chuck for my recently acquired $100 old heavy drill press (Kira ironworks japan 340 nsd) and was wondering if I should degrease it before I install, after seeing this I think I will give it a crack. Thanks John.
My favorite chuck are "cardinal" they taper down to the jaw end with the key fitting at the other end from that used by jacobs. Very useful when used in a lathe due to the extra clearance this gives. I have a number of keyless chucks but they have a major failing, if the drill jams or just bites that bit extra they can tighten up and then require a couple of stillsons or very large pliers to loosen.
John I’m surprised you’ve haven’t yet covered Toyota & their lack of ability to deliver vehicles. 19 months I’ve been waiting for my 70 series Cruiser (yes, more fool me) and I find it astonishing that it’s never talked about on these platforms. I haven’t even been issued a build date. I feel I’m too far gone to turn back now. It’s extremely frustrating.
Thanks John, i have a chuck that is very stiff when it's cooler out, maybe I'll attempt to give it s clean. The also make wedges to remove the chuck from the taper while its on a drill press.
Great video. A few notes: In the ultrasonic cleaner, glass is better than plastic. Thin plastic is better than thick. Also, for the grease, I'd recommend CMD. A lot less than used here (31:49) just enough to whet the surface. Like the amount that would be left by a toothbrush, moving parallel rather than perpendicular to the teeth.
Greetings from England. I've got a keyless that keeps binding when I use it on hammer action. Time for a rebuild, but I fear its going to be curtains. Great vid.
27:17 I rebuilt my first chuck as a child. My Father had one of the hand tighten chucks. I wound it full out and it fell apart. He made me put it together. It took a bit to work out but I did put it together. I own it now even though I don't use it much.
I'll just add that sometimes the reason the chuck key doesn't operate smoothly is because it's not the right chuck key for the chuck! I've come across that many times. People end up matching the wrong key with the wrong tool when tools get old and neglected. Not sure if there's a place to get hold of different chuck keys, but a lot of second hand tip shops have buckets of old tool bits you can hunt through to get parts for your tools.
I just bought a DeWalt cordless with stuffed chuck the other day. "dead simple to get apart" NOT! It wouldn't move at all, and wasn't open enough to let the LH thread screw out fully either in the end. I had to search DeWalt chuck removal on here, and basically remove the gearbox assembly and semi dismantle it to get a spanner on the back of the shaft. job done though( I think they squashed the original in vice grips or something). I used another chuck from a burned out AEG drill, had to do the same process for it also, so that was fun.
Have been holding out for this contribution since you said you were building up to do this, if we were interested. 17:35 Thea Vidale has something to say about repurposing kitchen equipment. Check out, "The green Tupperware bowl" 🤣
Honey!!!! Why do my cookies taste like WD-40!?!? You best start looking for #7! Chuck N. is a Colonel in my command training special units. I had the honor to be one of the few people to kick him in the nuts. Colonel flat nuts is a tremendous and caring commander who is truly loved by all he taught and served. I need to fix runout in a chuck. No one ever had to run out on the great Nor' Ass.🙊💕❤️🤗😇
As an apprentice auto electrician we had a brass jawed jacobs chuck for supporting armatures and rotors in the lathe. The jaws were available as replacement parts for a long time and then became a discontinued item. Fortunately another manufacturer came up with a live chuck that rotated on a bearing and the problem was solved.
funnily enough they do the same thing with conrods. hence why most important that you keep them matched together if you ever disassemble a engine with that type of conrod. (important with all engines as the rod and cap wear to each other but more so for those with the crack type bigend)
I bought a 40kg anvil. (I saw your video) A worn out pipe came out at work. I told the boily don't let that go it is the anvil stand. When we were installing the new pipes they refferd to that part as the anvil stand.
John great content. Can I refer you I'm sure you know on the trouble "This Old Tony" had with cheap Collets for his milling machine. That's surely worthy of another great Australian vlog!
John, you said that the drill press will ensure that the drill hole would be perpendicular to the surface. That assumes that the bed has been squared to the axis of rotation of the spindle. Please consider a video about squaring up the drill press bed to the spindle. thanks
Double Bugger. First I wish I’d seen this 3 years ago when I wanted save the steel chuck off a burnt out cordless drill and second I have a antique manually operated drill press that has a keyless chuck that needs reconditioning. Would be great to see a video on that please John.
A possible reason to make sure the jaws go back in the same places as they came out is to not change the centering of the chuck, in case there is a slight difference in the three holes the jaws fit in. Rearranging the jaws might make the drill bit wobble slightly. Admittedly the amount of off-centre that might happen is probably insignificant for a drill press, so perhaps this possible reason really doesn't exist either.
15:00 A 12ga shotgun and a crocodile bite is about 2 tonnes per square inch of force. A 20 tonne press is a small one and it is 10 times. When things go wrong it is fast. Keep it all square. Cover the eyes and anything you want to keep. You promote good stuff John. I have to control my buying ;)
Please note viewers !!!!! At least for a Jacobs 6A 33 taper, capacity 1/2" chuck Do NOT press off the sleeve with the jaws just below the nose of the body of the chuck. That positioning may not provide enough clearance for the sleeve to avoid contacting the base end of the jaws and thus could slightly damage the threads where they begin on each jaw. If a beginning thread on a jaw gets buggered slightly, that jaw may drop out of alignment from the other jaws when the jaws are fully extended. (The beginning of the threads may not be engaged by the split nut and thus that jaw drops down.) It is safer to have the jaws above the nose of the body of the chuck when pressing and use a short tube fitting over the jaws, so your vise or press (or bench top) can still bear on the nose of the chuck's body and not bear on the jaw tips. (I used a PVC plumbing fitting for this.) Great video and tip on how to sort out the sequencing of the jaw's position in the chuck when reassembling. If I was on my 6th wife, I might buy a sheet pan at the store for parts cleaning projects, thus avoiding taking one out of the kitchen. But then again, there's always lucky #7!
a realy handy thing to do with a normal hand drill chuck, is to get a long bolt of the appropriate thread and use it to fashon a handle, for said chuck You then have very usefull thing for grabbing and holding things with.
With a Morse taper arbour, its nominated as say 2MT 16G. (or any other type you may want) The 2MT is #2 Morse Taper which fits into the spindle of the drill press and the G16 is the truncated tapered hole in the top of the chuck. So you have to make sure both tapers are correct to obtain a proper fitment.
@@AutoExpertJC great vid thanks exactly what I needed confirmed.. I have a 16mm Jacobs ball chuck that was fully seized.. replacement val $500 plus !!.. soaked in caustic a few days then oxalic acid to free up.. has a 1/2inch male thread.. I'm hoping is Socket'd into the back of the chuck.. but it won't budge..
Ok i had to do it. Chuck Norris can keep both feet on the ground and still kick your ass. Oh thanks for reminding me i have a chuck with a loose holding screw i have been meaning to tighten.
Maybe it is bad for natural selection, but I always recommend power tool batteries are taken out before touching the working end. I've seen one too many people fit a recipro saw blade teeth to plam or grab a fist full of drill bit.
An excellent tutorial, thank you. I have a small Aldi drill press and it makes an oblong drill hole, the drill bit looks like it is off centre, but it is seated correctly in the chuck. How can this be fixed please.
Ultrasonic cleaner - also a great way to clean your watch parts for when you're doing a home-service on your Omega Speedmaster! I'd recommend getting a professional job if it were a Daytona.
Ha! Go back sixty or more years and that split ring technique was how they used to make the big end bearing carrier on a conrod. I'm not actually sure when they stopped doing it that way but I remember an old (B&W) American motor manufacturer's video demonstrating how this and other parts were made. (probably as part of a college course and it might have been GM but it was a while ago now).
Trust but verify... I was trying in my head to work out how the 123 pair swap works, then I wrote out the number ordering options if you counted them in sequence with rollover. There are essentially only two ordered sequences: ...123123123... and ...132132132... Swap any two sequential digit pairs and you're just switching from one to the other (sometimes with shift which is inconsequential in this case). It makes sense: if you assume random order and find the first 1, then there are only two next possible sequences: 23 and 32. But it wasn't immediately intuitive to me at least!
they do make Morse sleeves to go back the other way BUT not everywhere carries them and there expensive the other problem is the overall length becomes too long and you loose accuracy not a big deal in a free standing vertical drill but a bench size or lathe it is.
I cannot help you with Chuck Norris. But there were two vomits, Chuck and Ralph, walking along a street in New York one day. When Ralph started to get very emotional. Chuck asked Ralph what was wrong, Ralph replied oh my god I haven't been back here since I was a child this was where I was brought up.
Chuck Norris had the chance to pat a tiger. He crouched down and touched the tiger and a growl was heard. the zoo keeper said " You should carefully stand up and slowly walk away " after a few moments that is what the tiger did...
QUESTION? What grease would you recommend for the gearbox on electric drill? ALSO. What kind of Herculaneum strength do you have to hold that drill on the table and torque the trigger like that! Mine tried to body slam me
18:27 The hammer, every man's friend since the dawn of time. If you can find one in a few seconds everything becomes a hammer. My Cousin could not find a hammer quickly so he grabbed a rocks. After a few hits the rock split and cut his wrist. Off to the Doctor. They started calling him Caveman at work.
JC! How many used chux have you collected over the years! I can't believe that they aren't all completely stiff from years at the back of the drawer. Sorry, couldn't help myself...
i've seen a chainsaw connecting rod big end shocked apart in the same way. when reassembled the finish runs needle roller bearings. i think it was a small STIHL chainsaw.
