I don't think you could ever talk too much, the knowledge which you share is priceless for someone like me who knows absolutely nothing about this kind of stuff and find it intriguing.
Don't stress about people that say your table isn't flat or that you talk too much. I always enjoy your videos and all the information in them. Talk as much as you want....there's only wisdom in what you say. Thanks and take care.
My high school only had wood shop, I wish they had offered metal working, I might have well made a career of it. Instead, you are teaching a retired person. I appreciate your continuing to teach. You teach well, I grasp quickly what you teach. I also appreciate your offering multiple methods to achieve the same result.
Agreed. We had metal, wood and mechanical drawing back in the mid 60s in my high school. I think the purpose was to give exposure to 3 different trades. We also had in our county (PG County Maryland just outside DC) what was called a vocational school (Bladensburg SHS) which was focused entirely on the trades. The problem is that a lot kids at that age have raging hormones, problems at home and other issues that lead to a very short attention span and lack of focus. This causes many problems of course but most importantly the lost opportunity to learn something that will earn you a living.
Mr Pete you are a genius. For folks like me with injuries that don't allow shop time, spending time learning from you is the next best thing to learning the hard way! If you don't talk, we don't learn. Youre the best shop teacher on the tube!
I've worked with tools in a machine shop, on cars and running printing presses, took all kinds of shop classes 40 years ago, Seriously the person who says you talk too much is not very bright and will always have to rely on somone else to do things. The knowledge your passing down is priceless, its a lifetime of information you might not be able to ever find any place ecpt online. I almost always look to youtube or some place like it to learn, and I've been taking stuff apart from 1961 and putting it back together I was told when I was 1 I broke my dads horn on his car, when I was 3 I fixed it. This was a 1940's willys wagon. My dad loved it it had wood grain side panels. My dad always bought second hand cars. I do he same. You could fix them with a bobby pin and drive into a brick wall and it would always start and run. Old heavy but lasted 2 lifetimes or more. Now you tell me what's Green new cars that you have to replace every few years or cars you could drive a lifetime in? I'm telling you older stuff was built to last, today its built to last the warranty.
This came at the perfect time! I just bought an old Dayton, variable speed drill press and have been scratching my head as far as how to take the chuck off. The internals of the chuck need a good cleaning and its really difficult to do it on the press. Thank you!
I have a tradesman drill press T6744 model from 1969 and I was trying to figure it out how to remove the chuck !! I couldn't find the manual neither. thank you very much ! i will keep looking for the manual
Man, I spent hours trying to figure out how that Craftsman chuck was on there, and then I finally stumbled upon this glorious basket of information! Thank you so much for this video.
Great tutorial. Keep talking...it helps us understand it. I had never seen a chuck removed even though I worked in a machine shop for 10 years. Thanks..I'm ready to replace mine.
Thank you my Brother. You to are a Master. I have an old craftsman king sealy 1952. I just restored. But the mystery of the chuck removal was brought to light in your video. Thank you for the help. Wisdom is what I seek.
This is exactly what I was looking for! I had no idea what this kind of chuck was called, thought it was just stuck. After your video it took me less than a minute to take it off. Thank you!
Soooooooooooooooooooooooo glad you did a segment on this exclusive drill chuck. For 45 yrs ago, I bought a new Craftsman (Heavy Duty) drill press that had this chuck. I fought that thing (when I had to remove it) and it was a nightmare trying to get it off. So I got another drill press (and kept the Craftsman-still have it) and lo and behold, I found out "WHY" the new drill press chuck; would NOT work on milling cutters which came with the Craftsman drill press. In fact, there were many Sears brochures, that showed the drill press with a milling cutter in the chuck; used on a rotary table that Craftsman also sold as an accessory to this drill press. You Pete may have one of these brochures. Many years later, I found out why these chucks have the letter "C" next to the chuck number; and of course it means "collar". But today I learned HOW to get it on and off, because of you Pete. Thank you. But there is a better way and I hope you will make one, one day. And that is to make a spanner wrench; that is fitted precisely to this chuck. That SHOULD have been included with the Craftsman from day one, IMHO. If so , many of us (I believe) would not have the aggravation of getting that dadgum "Stuck" drill chuck off of the DP. Oh indeed yes. Thanks Pete. You are a life saver from Heaven (I am sure).
Excellent video and good explanation. Good to know there are some experienced and knowledgeable craftsman on the web willing to share their experience with all of us. Thanks
Excellent. I did the identical thing per your instructions and it worked perfect. I was ready for it to put up a fight but it came off easy. Thank you for the info.
Thank you so much for putting this together. I have a 1940s vintage craftsman drill press and I could not figure out how to get that collar off. I really appreciate you sharing this information!
Mr. Pete! I can't tell you how helpful you are. I have an older Jet R-13 drill press, and without you I would never have gotten the chuck off of the thing. The collar on mine is actually just a big nut, so once I set up my vise/clamps/allen wrench just the way you showed it was easy as pie to turn it off with a wrench, but I still loved seeing how you built the spanner tool for your collar. I wouldn't have shortened this video one second. Thank you, sir.
Sir, love your video. And I need to ask you, how were you able to get that constant c retaining ring back on that groove which holds the threaded collar on to the chuck? Was there a special retaining ring wrench that you used? If so, what was it? If you could get back to me on this I would greatly appreciate it. Ray @@mrpete222
I have the Jet 13R and I cant get that nut to go any further left (loose). I have loosened it, but it is up against the chuck and will not got any further.
Jacobs still makes these chucks. They have changed the part number from "633C" to "34-33C". The C means "locking collar". They also sell rebuild parts for the 633C. There are import versions, and Rohm used to make an equivalent also. Hope this helps someone.
Thanks for the video! I like the design of that chuck, though I suspect I won't ever actually use one. Never-the-less, I enjoyed your explanation of how to remove and install them. Thanks again!
A very timely video Mr. Pete. I am in the final stage of an Atlas drill press restoration and can’t for the life of me sort out how the chuck is held onto the quill. Fortunately the quill is still removed. I am heading downstairs to make a coffee and to try this approach to getting the “Truman Era” chuck off, lol. Cheers Sir.
So I did get the chuck off the machine thanks to you. However, when I took it apart all the threads were shattered into pieces. It is a dayton floor drill press with a chuck with a threaded collar. I emailed grainger with the model number and they couldn't find record of it. Do you have any advice on how I can find the right replacement chuck?
Guess the thumbs down people hated the color of your shirt, they surely could not have disliked to info. Love all your videos mrpete. I talk constantly in my videos also, so much to say so little time😀
It's been a while, but I have this exact setup on a floor standing Craftsman drill press from about 1973 I think. I had spent some time trying to figure out what needed to be done to get the chuck off, and this was it. Thanks for the good discussion.
I wish I would've found your video sooner. I am having a difficult time removing chuck. Your solution is ingenious. I hope I can still get it to come off.
Great Information Mr. Pete. I had an issue with a Walker-Turner drill press about 10 years ago where I felt the need to remove the chuck. Without having any prier knowledge, I unscrewed the collar with a spanner & thought it would press itself off if I kept on turning it. No go. It was tight With my new found tool 'The Internet' & a link to 'The practical machinist' website, I asked the good people for tips. At least one kind person told me that the inside of the chuck (the throat) is soft steel & can be drilled easily & then a punch could be inserted to knock it out or pressed out (with the spindle dismantled of course). If I remember correctly, I was able to chuck the spindle in the lathe & drill out the center very carefully as not to drill into the spindle (there is a little air gap between the chuck & the spindle). I drilled it to just big enough for the punch I wanted to use. It worked. just food for thought when all else fails. By the way, the chuck still works fine.
Great to find this - Same Chuck setup on my old Sprunger press. I had it apart to replace the bearings, but removed the entire spindle set up with the chuck attached. I'm glad to get the tip about the Chuck Key end... I tested mine, and it's a glove fit! Thanks.
Fire years back, sure glad you did this Lyle. That Craftsman's I bought December 2022 has that locking darn collar! Thx to your videos, ole Bear won't screw up now removing the chuck.
You can still buy these Chucks. Jacobs still makes one model. I recently bought 2 of them. The lowest price to buy it was Sears online. Abotu $90 as I recall. Thanks for all your videos
Thank you very much for this! Now I can proceed with repairing my Craftsman drill press. I never messed with it because I wasn't sure how to remove the chuck.
Thank you for this video, I have diferant chucks and adapters but could not get the one that's in it off. This is one of those why didn't I think of that moments when I saw the chuck key in the vise lol. Enjoy your videos, thanks for sharing.
I never leave a comment I'm glad and thankful I learn from this video but unfortunately I believe I passed away from old age somewhere towards the middle
The retaining function of the 1 1/16"-20 threaded collar was a bonus. The principal function was to make removal simple to facilitate exchanging the chuck for other spindle adapters. At one time Delta offered ½" bore, MT1, MT2, ½' threaded shaft w/ flange for grinding wheels, and a ½" shaper spindle. Probably Walker-Turner, Duro, etc did as well. A stamped steel pin spanner was standard equipment with a new Delta machine, but of course was often lost. In the case of the US-made Delta 15" 6+6 drill presses, the only way to get a MT spindle was to install one of the adapters. The various adapters were developed as an improvement over the prior state of the art, where exchange of the entire spindle was required to obtain the various spindle ends, as was the case with the original Delta 14" drill press (commonly known as DP220). Craftsman offered elementary collet chucks, as did Millers Falls. Some of these used a tapered pin for removal as an economy measure. BTW, even if the locking collar prevents side loads from dislodging the Jacobs chuck, damage can still be done to the chuck itself. That is when the the ½" bore adapter was meant to be used, for sanding drums, router bits, etc.
Thank you for all your detail I've always wondered how this drill press works and how to get this chuck off its arbor I dont have the collar but do have friends with cnc machines maybe make me one.you just got a subscriber for life.
Jacobs does still manufacture a collared chuck in 33JT. The Jacobs model name is 34-33C (C stands for collar) and chuck key K3C. Jacobs part number 14451 for chuck and key. Jacobs part number 14449 for chuck alone.
Thanks Mr.Pete, I just got the chuck off my 24 in tall bench drill press, Duracraft UL-30 FROM 1982, the spindle shaft is 5/8" and tapers down from there. I just got it, used of course, came with 5 chuck keys, 1 was even a multi tip, not one would fit correctly, wouldn't ya know. have a great day, thanks again
When I changed the chuck on my drill press I just turned down the taper and threaded it to fit a chuck I could get easily, which was a lot better than the broken one it had when I got it on auction. Got a nice keyless chuck as well, for a really good price as well, and while the runout is not great ( needs new spindle bearings, but probably also a new shaft to solve the wear in it as well) it does do the job well.
Thanks for making this video. It is a great help to me. I have an old Craftsman drill press with the thread above the Jacobs taper but no retaining ring. The Chuck that came with the drill press has some run-out and the taper is a bit scuffed up. I am thinking I have to get a new chuck to eliminate the run out problem. Now I will look around for a chuck with a retaining nut.
Thank you so much for passing on this information. This is exactly what I needed to know to remove my Jacob 633C chuck. I think I also need to remove the arbor because it is bent. Looking for some help on that also. Thanks again!
Who wouldn't want the information on Jacob's chucks? Who wouldn't want all the information Tubalcain has to offer? Thanks for sharing Mr. Pete!
Amen and AMEN !
I totally agree. That's why I asked sometime ago that posters who give him a thumbs down to tell why the thumbs down. No takers so far.
Excellent video. This gives me the information and confidence to replace my 40ish year old craftsman Chuck
I don't think you could ever talk too much, the knowledge which you share is priceless for someone like me who knows absolutely nothing about this kind of stuff and find it intriguing.
Amen and AMEN!
I agree! What you have to say is priceless. Now to find a new chuck.

LMAO @ Most of these chucks have been on since Harry Truman was in office. Too Funny. Great tutorial video. @@mrpete222
I too am in the middle of restoring a Craftsman 150 DP. Thankful to find your video for the chuck. Thank you for making it. Nicely done.

Another great video from mrpete222 I like the way he not only shows you how to but also explains why
Thanks
This video just saved me an entire weekend of frustration. You are a wealth of knowledge and I thank you for sharing it with us.
👍👍
Perfect! Thank you. Guys like you with all the knowledge are what we need.
Everytime I get hung up on something in my journey of learning I find Tubalcain has already made a video about.
Once again, thank you sir!
I know it's been awhile since you put this out. But thank you for the lesson. It was very easy to understand. Thanks for sharing 👍 your knowledge.
Thanks
What a great job this has been a puzzle to up to now we need more teachers like you
Great tutorial. Keep talking...it helps us understand it. I had never seen a chuck removed even though I worked in a machine shop for 10 years. Thanks..I'm ready to replace mine.
Thanks Mr Pete..... thought about taking the chuck off my 1940's walker turner press for cleaning. This video came at the right time !
I've been watching your backlog of videos...so when I needed to get my chuck off you were the first pick. PLENTY of detail. Thanks.

No doubt, Mr Pete is truly "your internet shop teacher." He's a valuable instructor from whom I've learned a LOT!
pat dee and attach the custom spanner to the machine so it can be found when needed
Glad I found this I ordered a new chuck for my old delta 14-040 I would have never figured this out GOd bless you
Thanks for the tips! I soaked mine in Jb80 for a few days and got the collar off just using a drill bit end by hand! Worked great!
👍

You don’t talk too much! Thanks for sharing your experience and knowledge!
Thanks
Excellent lesson in enigmatic collard Jacobs chucks.
Thank you! This is exactly what I needed. Every other how-to I have seen talked about chucks that don't use a threaded collar.
Yes
I had the same problem and cant get a manual for it either lol.
Jacobs still makes these chucks. They have changed the part number from "633C" to "34-33C". The C means "locking collar". They also sell rebuild parts for the 633C. There are import versions, and Rohm used to make an equivalent also. Hope this helps someone.
Exactly what I needed in disassembling my 1942 Walker-Turner Radial Arm Drill Press with a stuck Jacobs 33 taper chuck! Thanks!
Thanks for the video! I like the design of that chuck, though I suspect I won't ever actually use one. Never-the-less, I enjoyed your explanation of how to remove and install them. Thanks again!
Amazing ! I’m restoring an Atlas 63 drill press and this helped me out so much !
A very timely video Mr. Pete. I am in the final stage of an Atlas drill press restoration and can’t for the life of me sort out how the chuck is held onto the quill. Fortunately the quill is still removed. I am heading downstairs to make a coffee and to try this approach to getting the “Truman Era” chuck off, lol. Cheers Sir.
Interesting info about the Jacob's tapers. Haven't seen much about this before, although I knew they existed. Thanks Lyle.
Thanks again Mr. Pete! Now you have another short drill bit.
Thanks again! You just saved me a lot of time and aggravation restoring my old Buffalo drill press w/a bad chuck.
Thank you! I would've never figured that out if I didn't find your video!
Glad I could help!
So I did get the chuck off the machine thanks to you. However, when I took it apart all the threads were shattered into pieces. It is a dayton floor drill press with a chuck with a threaded collar. I emailed grainger with the model number and they couldn't find record of it.
Do you have any advice on how I can find the right replacement chuck?
@@nathantweeddale9057
Is there a model number on the chuck
Check Granger and McMaster Carr
Guess the thumbs down people hated the color of your shirt, they surely could not have disliked to info. Love all your videos mrpete. I talk constantly in my videos also, so much to say so little time😀
It's been a while, but I have this exact setup on a floor standing Craftsman drill press from about 1973 I think. I had spent some time trying to figure out what needed to be done to get the chuck off, and this was it. Thanks for the good discussion.
👍👍
Just the info I was needing Thank you so much for your Knowledge Mr Pete!!!
I wish I would've found your video sooner. I am having a difficult time removing chuck. Your solution is ingenious. I hope I can still get it to come off.

Great Information Mr. Pete. I had an issue with a Walker-Turner drill press about 10 years ago where I felt the need to remove the chuck. Without having any prier knowledge, I unscrewed the collar with a spanner & thought it would press itself off if I kept on turning it. No go.

I drilled it to just big enough for the punch I wanted to use. It worked. just food for thought when all else fails. By the way, the chuck still works fine.
Great to find this - Same Chuck setup on my old Sprunger press. I had it apart to replace the bearings, but removed the entire spindle set up with the chuck attached. I'm glad to get the tip about the Chuck Key end... I tested mine, and it's a glove fit! Thanks.
I'm glad you like the video
Thanks!, Really enjoy your videos.
As always you have solved the mystery...Thanks
That was great. I'm trying to troubleshoot some wobble and this will help isolate the spindle from the chuck and for seating as the issue. Thanks!
That was excellent and informative info! Thank you
Fire years back, sure glad you did this Lyle. That Craftsman's I bought December 2022 has that locking darn collar! Thx to your videos, ole Bear won't screw up now removing the chuck.

Fantastic, this helps so much. I just got an old clausing drill press with this exact chuck and I couldn’t figure this thing out

Very Good Mr.Pete, Thank You.
Super helpful! Thank you so much.
Perfect. This let me know how to pull the chuck of my General 340 drill press. Many thx.
You are the greatest teacher! Thank you!
Thank you very much
Thank you very much
Thanks Mr. Pete, I got mine off with minimum hassle...I even found a spanner that fit (I only have 3!).
Thanks mr Pete. You just saved me. My old craftsman drill press is on the mend now.
Yes
Thank You, sir ! Now I can hopefully purchase a new chuck that’s a 3/4 rather than the 1/2 inch currently. It’s an older Rockwell. Great video 👍👍
You can still buy these Chucks. Jacobs still makes one model. I recently bought 2 of them. The lowest price to buy it was Sears online. Abotu $90 as I recall. Thanks for all your videos

I was always wondering about that on my drill press....thanks
I've never run across on of those but its good to know about them anyway. Seems like a really bullet proof design, wish they still made them.
Thanks ,I have a duro drill press ,been wanting to take Chuck off but did not want to damage it ,thanks again
Mr. Pete can never talk too much...
Very helpful, thank you for sharing.

yes--the delta catalog shows all the accessories--wish I had that morse taper adapter
I was going to show that catalog, but thought no one would care
We care
THANKS for caring!

Very good, I did not know that. Thanks Mr. Pete!
I sure am that’s what I’m doing now on my powermatic 1150 . Ty mr. Pete

I often wonder how that was on there. Thank you Mr Pete
Thank you. I have looked for years at how this was done.

Wery informative well explained Thanks
Thanks
Thanks very much, I was looking at a new old drill press i just got and want to change out the chuck.
Very helpful thanks
Thanks Mr.Pete, I just got the chuck off my 24 in tall bench drill press, Duracraft UL-30 FROM 1982, the spindle shaft is 5/8" and tapers down from there. I just got it, used of course, came with 5 chuck keys, 1 was even a multi tip, not one would fit correctly, wouldn't ya know.
have a great day, thanks again
THANK YOU...for sharing.
When I changed the chuck on my drill press I just turned down the taper and threaded it to fit a chuck I could get easily, which was a lot better than the broken one it had when I got it on auction. Got a nice keyless chuck as well, for a really good price as well, and while the runout is not great ( needs new spindle bearings, but probably also a new shaft to solve the wear in it as well) it does do the job well.
This was super helpful and hopefully I can use this to get the chuck out of the old rockwell delta 15-665 I am working on refurbishing. :)
Thankyou that was what I needed.
Great info to have. Thank you.
Thanks, great video
Thanks for sharing sir.....
Thanks for making this video. It is a great help to me. I have an old Craftsman drill press with the thread above the Jacobs taper but no retaining ring. The Chuck that came with the drill press has some run-out and the taper is a bit scuffed up. I am thinking I have to get a new chuck to eliminate the run out problem. Now I will look around for a chuck with a retaining nut.
Thank you for watching
Great information. Thanks
Do you work in the garage in the summer and basement in the winter? Your information is always helpful. Learn something new from you almost daily.

Thank you so much for passing on this information. This is exactly what I needed to know to remove my Jacob 633C chuck. I think I also need to remove the arbor because it is bent.
Looking for some help on that also. Thanks again!
Glad it helped
Thank you.
Thankyou. Well explained.
