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.

[@Phil_McAvity]

[@chrishewitt4220]

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

[@Rockbottomsurf]

Rickie Lee Jones’ chuck key’s in love.

[@captcarlos]

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.

[@AutoExpertJC]

I was looking at a JT3 or 4 I think, but they're hard to eyeball.

[@captcarlos]

All good. Someone commented on how long this was.. I didn't notice... Keep up the good work.

[@marconi-id7tf]

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.

[@roberthunter6927]

What's the drill with chucks? He went from Prince to King of Britain, I believe! :-)

[@chrisforgan731]

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)

[@kurothot2203]

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.

[@chrisforgan731]

if its new dont bother yet. but if its worn and stiff then yes a clean and re grease would help.

[@johngarland3550]

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.

[@Equiluxe1]

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.

[@andoletube]

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 pulled a Jacobs chuck apart the other day. I had the jaws back just under flush like shown in the video, but it still caught on the rear of the jaws when pressing it off. I later saw instructions from Jacobs where they recommended having them halfway from closed to flush. I'm guessing it was unique to the size chuck i had, 3a from memory. Just thought i would mention it in case someone else is wondering why the damn thing won't move past a certain spot and continues to press harder. I'm glad I went easy, closed up the jaws a bit and didn't do any real damage

im learning 1 trick every 5 mins in this video, like wtf. didnt know Christmas comes in july. found the same chuck on taobao, cost like 5$ for the big one. not trying to bash or anything ,just so everyone knows the MSRP in china for this item.

[@Mark_Bridges]

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.

[@deankdx]

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.

[@dancewithml]

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

[@eddents]

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!

The Simpsons ruined chucks for me, as now whenever I see one I think of Sneed's Feed and Seed (formerly Chuck's). It doesn't help that I have a zoomer spawn that's old enough to watch M-rated movies who thinks it's the funniest visual joke ever.

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.

Some of these arguements might make less sense in a few years if we manage to decarbonize electricity production and further reduce the price of solar energy. If solar energy get ssufficently cheap then the process of making things like steel could get much less carbon intensive.

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 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.

[@nettlesoup]

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!

[@neffk]

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.
