Here's how to remove a threaded collar type Jacobs chuck from your old drill press. Also a brief discussion on JACOBS TAPERS. Please subscribe, like, and tell your friends.
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.
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.
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!
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.
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.
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!
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.
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).
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
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!
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.
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.
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.
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!
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.
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.
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.
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?
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.
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.
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
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
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.
I have an old Sterling bench type Mickey Mouse drill press that was given to me and it has been working great for close to 20 years. Lately, the chuck has decided to not work very well, so I saw your video here and decided to try to take the old chuck off. At first, it gave me all sorts of grief...until I got sorta mad and pulled out my "blue tip saw"... also known as a torch and fired it up putting just a small amount of heat on the old chuck. I also told it that if it gives me any trouble at all, I was going to cut it off. I guess it was listening because I gave the collar thingy a slight tap and low and behold, it started to turn. Thank you for your advice and schooling.
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.
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.
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😀
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
Thanks. Picked up a very clean 1970 craftsman drill press and it had the threaded collar chuck (which I hadn't seen before). This video helped a lot. Edit: Oh, I forgot to say why..., the chuck on it was fine, but the wife (who the press is for) wanted it replaced with one of those hand-tighten speed-chucks.
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
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!
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!
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.
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.
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.
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.
One thing to remember is to not over tighten the threaded collar the retaining ring can snap off. I had a Rockwell 17" that I received in that condition that was thought to have the bearings seized up but turned out to be the collar had unscrewed up against the bearings and locking them!
Mr Pete, thanks for the video. I know you said you don’t have the time, but for safety’s sake, you should find the time to remove the mushroomed over edges on your copper hammer. The punch you were using in the video also had a little mushrooming that could stand to be removed.
I found a big Jacobs Chuck at an estate sale that had 1 1/2- 8 threads on the back that fits my atlas lathe, I'm so happy with it because I don't have collets.
I had 3 holes in my collar. I made something similar out of a piece of bar stock drilled 2 holes and welded a handle on it. Then I put the shank end of 2 drill bits through the holes into the collar. Then I used a small tube air chisel with a hammer attachment on it to impact the handle I made and it came loose fairly easily. It would not come loose by hand at all. I tried the punch trick but it was just stuck on there too tight. when I reassembled I cleaned the threads real good first. It looked like they had put some sort of assembly lube on there that turned to really thick goop. I used penetrating oil on it over night before I tried taking it off but it didnt help at all. It wasn't rust it was goop. Almost like the thickness of old cosmoline. BTW if you put 2 pin holes in it, it holds itself onto the collar pretty well. I like your trick with the vice and the Alan wrench. I'll have to give that a try next time. If I live that long. LOL! PS. I had to take it off because the chuck was really stiff and didnt move well. It works great after I cleaned it. I don't really use my drill press with any side load attachments but I tried to use a Morris taper Jacobs chuck in my Bridgeport J-head many years ago trying to do some quick and dirty machining of a non critical part and it didn't work very well. The Morris taper fit fine but the side load made it come loose and almost broke my $40 end mill. That was a lot of money in 1975.. I figured it would be fine because it was just aluminum but when it fell out it hit the vice...It was auto feeding too so I had my back turned to it. Scared the crap out of me. Live and learn...
Aceroadholder True but this was an old J-head and I wasnt looking to do anythin but take .025" off a mounting bracket. Not critical. so instead of sorting through a box of collets I just grabbed what I thought would be fast. The J-head has a drawbar but the chuck wasn't threaded.
Hello Mr Pete I just picked up this exact Jacobs chuck that is threaded it is old old possibly from Truman's day and somebody dropped a bomb on this old spindle too . The top of the spindle is bent at the pulley . you say throw it away !?? but i bought this so i could restore it !! We cannot throw this history away !! I can send you some video if you like and maybe we can make a video about saving an old man - The drill press I mean Ha Ha
I have owned and played with many drill presses old new expensive and Chinese. Never seen a threaded chuck in the U.K. always morse taper this must be a USA thing. Many thanks regards Chris.
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.
I just bought an old Craftsman drill press with this collet type chuck. There is some runout on the chuck so I will remove it and check the taper for runout. Hopefully I can replace the chuck and all will be well. wish me luck. Grin
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.
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.
Excellent video. This gives me the information and confidence to replace my 40ish year old craftsman Chuck

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

Perfect! Thank you. Guys like you with all the knowledge are what we need.
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 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!
👍
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.
THANK YOU. THANK YOU. THANK YOU. I've been racking my brain trying to figure this out.
You are so welcome!

What a great job this has been a puzzle to up to now we need more teachers like you
MrPete don't worry about repeating, most all humans learn better through repetition. Thanks for another great 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.

Excellent lesson in enigmatic collard Jacobs chucks.
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

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

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.
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!
Thanks Mr. Pete, I got mine off with minimum hassle...I even found a spanner that fit (I only have 3!).
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😀
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 👍👍
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
I sure am that’s what I’m doing now on my powermatic 1150 . Ty mr. Pete
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
Thanks. Picked up a very clean 1970 craftsman drill press and it had the threaded collar chuck (which I hadn't seen before). This video helped a lot. Edit: Oh, I forgot to say why..., the chuck on it was fine, but the wife (who the press is for) wanted it replaced with one of those hand-tighten speed-chucks.
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.
Interesting info about the Jacob's tapers. Haven't seen much about this before, although I knew they existed. Thanks Lyle.
Thank you for taking the time to make this.your knowledge is very valuable.
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
I've been looking for a video just like this for years. Thanks. There really isn't much info regarding this removal process.
Thanks mr Pete. You just saved me. My old craftsman drill press is on the mend now.
Yes
That's the chuck I need for my Delta Rockwell. You are correct, I couldn't find it being sold anymore.
It is still available today at MSC machinery. Click on the link:

I always enjoy your videos thanks for sharing 👍
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!
Thanks again! You just saved me a lot of time and aggravation restoring my old Buffalo drill press w/a bad chuck.
Mr. Pete can never talk too much...
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
Tubalcain is my hero!!!!!!!!!!!!!!
Thank you. I have looked for years at how this was done.
👍👍
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.
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.
You are the greatest teacher! Thank you!
Thank you very much
Thank you very much
Thanks ,I have a duro drill press ,been wanting to take Chuck off but did not want to damage it ,thanks again
wow thanks very helpful I just bought a craftsman 150 today & had no idea how to remove chuck
Glad I helped
Thanks very much, I was looking at a new old drill press i just got and want to change out the chuck.
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.
Thanks
Thanks!, Really enjoy your videos.
Always interesting and entertaining.
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.
One thing to remember is to not over tighten the threaded collar the retaining ring can snap off.
I had a Rockwell 17" that I received in that condition that was thought to have the bearings seized up but turned out to be the collar had unscrewed up against the bearings and locking them!
Super helpful! Thank you so much.
Mr Pete, thanks for the video. I know you said you don’t have the time, but for safety’s sake, you should find the time to remove the mushroomed over edges on your copper hammer. The punch you were using in the video also had a little mushrooming that could stand to be removed.
I found a big Jacobs Chuck at an estate sale that had 1 1/2- 8 threads on the back that fits my atlas lathe, I'm so happy with it because I don't have collets.
nice find
Excellent...this is exactly what i needed to know. Cheers
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. :)
I had 3 holes in my collar. I made something similar out of a piece of bar stock drilled 2 holes and welded a handle on it. Then I put the shank end of 2 drill bits through the holes into the collar. Then I used a small tube air chisel with a hammer attachment on it to impact the handle I made and it came loose fairly easily. It would not come loose by hand at all. I tried the punch trick but it was just stuck on there too tight. when I reassembled I cleaned the threads real good first. It looked like they had put some sort of assembly lube on there that turned to really thick goop. I used penetrating oil on it over night before I tried taking it off but it didnt help at all. It wasn't rust it was goop. Almost like the thickness of old cosmoline. BTW if you put 2 pin holes in it, it holds itself onto the collar pretty well. I like your trick with the vice and the Alan wrench. I'll have to give that a try next time. If I live that long. LOL!
PS. I had to take it off because the chuck was really stiff and didnt move well. It works great after I cleaned it. I don't really use my drill press with any side load attachments but I tried to use a Morris taper Jacobs chuck in my Bridgeport J-head many years ago trying to do some quick and dirty machining of a non critical part and it didn't work very well. The Morris taper fit fine but the side load made it come loose and almost broke my $40 end mill. That was a lot of money in 1975.. I figured it would be fine because it was just aluminum but when it fell out it hit the vice...It was auto feeding too so I had my back turned to it. Scared the crap out of me. Live and learn...
Some small mills, like the Benchmaster, used Morse taper tool holders.. but they use a draw bar to make sure it doesn't come loose.
Aceroadholder True but this was an old J-head and I wasnt looking to do anythin but take .025" off a mounting bracket. Not critical. so instead of sorting through a box of collets I just grabbed what I thought would be fast. The J-head has a drawbar but the chuck wasn't threaded.
I often wonder how that was on there. Thank you Mr Pete
Hello Mr Pete I just picked up this exact Jacobs chuck that is threaded it is old old possibly from Truman's day and somebody dropped a bomb on this old spindle too .
The top of the spindle is bent at the pulley . you say throw it away !?? but i bought this so i could restore it !! We cannot throw this history away !! I can send you some video if you like and maybe we can make a video about saving an old man - The drill press I mean Ha Ha
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.
I have owned and played with many drill presses old new expensive and Chinese. Never seen a threaded chuck in the U.K. always morse taper this must be a USA thing. Many thanks regards Chris.
Just the info I was needing Thank you so much for your Knowledge Mr Pete!!!
As always you have solved the mystery...Thanks
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
I just bought an old Craftsman drill press with this collet type chuck. There is some runout on the chuck so I will remove it and check the taper for runout. Hopefully I can replace the chuck and all will be well. wish me luck. Grin
Thanks. Good luck
Very Good Mr.Pete, Thank You.
Thank you, Mr.Pete. That was indeed, helpful. I can just imagine the mess one would create if they tried to remove it using a pair of wedges!
That was excellent and informative info! Thank you
