I really like the place names in the UK. Midsomer Norton, Child Okeford - cool. In NZ we just stuck a compass heading on some word and called it good enough. Pretty sad, really. Cheers to you, Pommies!
Hi Steve, great video as usual, but can you please get rid of that hoodie cord that's hanging down close to the machines, I kind of like your face as it is. All the Best to you and family for the new year from us in Tassie.
No, you didn't choose thje most complicated approach. You could have fitted a power drawbar. :) Love how you have Cora inspect all the work. She's a great QA department. :) Have a safe, healthy and prosperous 2023!
I believe the pin is there to enable you to unscrew the drawbar if the top threads loosen when trying to unscrew the drawbar. If that were to happen without the pin, you’d have the drawbar stuck in the toolholder and no easy way to remove the drawbar.
I hope the view from the window still makes you smile. Every time I see you working on the lathe I am reminded that when I first started watching your channel you were confined to that corner of the shop.
Catty wompus is a technical term, not to be confused with wompus kitty😂 My first paying job was in a diesel and automotive machine shop. I ran a short bed Hendey lathe there, and occasionally had to chase threads on it. That old Hendey was a pleasure to thread on. Dandy fix for your drawbar conundrum. Happy New Year to you and yours Steve and Elizabeth! Regards, Duck
So nice to see you using your machine tools to make your machine tools even better. However, I'm just a woodworker but even I was nervous about those hoodie strings hanging free from each side of your neck.
I'll never forget when a pinned on drawbar nut sheared whilst milling and sent the tool flying across the shop. Luckily it went away from me, but it could have come right to me. This happened on a 1980's manufactured ENCO mill drill with an R8 taper tool holder. The retaining pin on the drawbar nut was very soft steel. This explains why Do-All threaded the rod. I immediately made a solid bar component with a machined hex head. Not a pleasant experience. Safety first.
I was glad to have Kwik-Switch on my Bridgeport. Although I was a Falconer, I still love the squirrels. I hope you still see some of your old friends. I was watching some videos of a woman who restores machines and rewires motors. She is amazing and she doesn't have access to the best tools. It would be so cool to see her visit your shop or Adam's or others in your group. I can't remember her name or link, but I'm sure that others do. She might be Vietnamese and I don't know if she speaks English but she is amazing.
Look at the way corra looks at you. How can you ask if she's a good girl, she's beautiful. ❤️❤️ Lovely Saturday with you all in kentucky again Steve. Happy New year xxx
Great work as usual. I have never noticed you leaving chuck keys in chucks before. I believe an industrial standard for chuck keys is, "It should either be in your hand or in its holder."
Your Doall uses a NTMB 40. CAT or BT are cnc using the pull stud to secure it. The taper CAT and BT will work, one thread is metric the other is imperial.
Steve, another great reason most old school manual machinists prefer a Series 1 Bridgeport with 8C collets and a power collet changer ontop. (We even have Servo power knees & tables on them) Their just a more useful machine to run and you don't ever have to climb all the way up on the table to pop the draw bar screw out every time you want a different cutter or drill chuck. We use to have a Index Mill the size of your DoAll mill that had a 40 taper but we all were getting to old to climb up on the table every time we had to change a collet as it was just to hard to run compared to our Bridgeport's. If we had a big fixture or jig plate to machine to big for the Bridgeport's 42 inch table, I also got a old #3 Cincinati mill with a ton of 50 taper collets, but 90% of our mill/ drill work is done on the Bridgeport's and is fast & easy with the British Newall DROs I put on everything.
I always watch you work, and you always do great work, but that string hanging off your sweater just put it inside the sweater, and continue to make great videos, be bless.
Always a pleasure to hang out and watch and learn, but miss seeing Elisabeth in there by your side.Hope she is ok? One question, I was thought 55,+ yrs back to secure bits in a keyed chuck to snug ever hole, not one. But you don't seem to have any slippage by just tighting one location. Happy and safe New Happy to all, Bear
Nice! I like the way you present the part to Cora for a sniff. I do the same with almost everything with my hound, Pandora (Pandy). They do like a good snort.
I am a real believer in projects that benefit the shop/business. A few hours spent here and there can save thousands of $ in time. What a great way to start a new year than with an hour visiting with you. All the very best to you, Elizabeth and the rest of your clan. Take care eh !
#leans-in-close-and-whispers: steve; I think what you're calling a cat-40 holder is a NMTB 40 holder (the straight part at the top is the giveaway.) The others look like cat40; with the groove in the flange at the base of the taper roughly around the middle. BT40 looks a lot like cat 40 but the groove is towards the top of the flange part at the base of the taper. the *ONLY* reason I know this is I have a NMTB 50 machine and a CAT40 CNC machine. Love your work and this channel!!!
That Doogie keeps watching , you'll come out one day and she'll be machining the job for you. Hope you and your family have a happy and prosperous new year.
Good morning Steve. I hope that 2023 is a great year for you. I see that you are taking care of Elizabeth's truck by keeping it in the shop. Stay safe.
Steve, I’ve watched your channel off and on for a while. Recently I decided it was time to get a mini lathe and start doing what I was watching. Having made several parts (with mixed success but lots and lots of learning) I totally understand so much more of what you do and discuss now. I’m going back and watching older videos because there’s so much great info in them! Thanks so much for sharing what you do! I may be 59 years old and just starting into machining, but I still love to learn.
Hey Steve, Just a correction on your naming of your tool holders. The Cat40(5/8-11 Thread) and BT40(M16x2.0 Thread) holders are pretty much the same and both have the screw in pull stud. The one you refer to as cat40 in the start of the video is actually a NT40 or NMTB40 with the 5/8-11 threaded protrusion on the end. I'm pretty sure you can buy screw in adaptors to suit the CAT and BT holders the allow the use of the original drawbar. Keep up the great video's and Happy New Year to you and the family
Thank you Barney, I'm glad you clarified the tool holders, it was driving me up the wall listening to them being referred to incorrectly, details do matter.
Thanks also Barney. Right on all accounts. Manual machines would for sure have NMTB40. CNC machines with an automated toolchanger would have the CAT40, from the long line caterpillar zig zag chain style, or the BT40 for CNC machines with a rotary automated toolchanger. People need to know the lineage and history of tools so they know exactly what they are talking about. It is unreal how many people think their truck has a full floating axle, when it is really a semi floating axle. Details mean everything. And incorrect knowledge gets passed on as fact. Especially in this day and age where people think they HAVE to know the answer. Truth is they don't. Being honest in their ignorance will get them farther, because it opens the door for the opportunity to learn. Wisdom for many people does not come as fast as they wish it would come. So you have people faking it because they think they need to fake it to survive. Far from the truth, but you can't tell them that. Their ego gets in the way. I am talking about the society we live in today. Not directed at Steve. He is a solid dude. Just that I see so much faking it today, especially in youtube. Viewer beware. On youtube an in life. ------Doozer
Having done this conversion on a mill myself, you can get screw on adapters for CAT40 and BT40 that will convert them for use, but they're expensive unless you make them yourself and they're a pain in the behind to make if you use the right materials. I converted my mill from NMTB40 to CAT40 with a draw bar replacement because CAT40 tool holders are the most common in the secondary market and therefore cheapest to buy. BT40 is almost as common. I don't ever plan to go back or use anything other than CAT40.
@@kooldoozer Actually, tool holders are independent of tool changer type. I have a 20 slot rotary tool changer with cat40 holders. The CAT series holders were originally a standard from the Caterpillar equipment company - they wanted a standard holder type for all their machines. BT taper is an evolved version of the CAT tapers developed by Japanese machine tool builders. BT tool holders are symmetrical around the spindle axis, and the CAT40 standard holders are not. BT holders also have a wider flange than CAT. DV (Deutsch) holders also exist, and are similar to CAT holders with an orientation notch added. All three have the same taper as the older NMTB tool holders of the same size. Tool changers are designed for a specific tool flange, so the tool holders for a machine should be matched to the changer that is present, regardless of its mechanism.
Happy New Year Steve, Elizabeth, Cora, and Grits! Watched yesterday and fell asleep. Had to re-watch today and thank you again for sharing the good, bad, and ugly. Always instructive and inspiring. Thanks for taking the time and expending the effort to share. God Bless!
Very nice project with great results. You are very talented at what yo do. But you sent shivers done my back at 48:48 when you took a measurement with the spindle turning and your fingers that close to the spinning cutter. Just saying I enjoy your videos and would like to continue watching them. Stay safe and have a good new year.
Love these videos. Using the tool to make the new tool for the tool. You can understand why they have the tool maker profession in engineering shops. They are they people that allow us to make more stuff.
Really nice work, and a very informative job. You are a talented young man. I really look forward to seeing you Saturday morning's. Have a safe new year, and see you next year.
I always like your sit down thoughts and the shop tours. The fact that you are able to take a 12 month sabatical is wonderful, it gives you the time to try out if something else will work for you, in the knowledge that there will presumably be a job for you at the end of it. To be honest I'm sure any number of companies would be glad to have you if you decide to go back to work again. This channel is the very best advert for your capabilities. Enjoy New Zealand, I think we should have been there next year, a retirement present to ourselves, but life got in the way big time. My father went years ago and my brother went on honeymoon, thought it was fantastic. I have never been, despite spending 15 years travelling the world in the merchant navy.
@@bcbloc02 Apologise, you are right it was, I wondered why I couldn't see it on his channel. I shouldn't have two or more windows of YT open at the same time.
I see Cora didn't help you with holding the other end of that shaft while you were driving that pin home. Must have fallen asleep next to the the heater again. Oh, well, good help is hard to find. Happy New Year, hope 2023 is good to all of us!
Steve have your small thread on the very end and step it up to the next larger thread and at the other end have it threaded with a nut on the top to make up for the longer and shorter draw bar just use one bar for both sizes
Steve, Always watch, but never comment.. My Friend...get a power draw bar on that...The air gun type would work just fine, saves you from getting the ladder out and keeps your rotator cuff healthy. It should be retrofittable to the tooling you have, and you'll never regret having it. Awesome content! Just worry about ya.
Thanks for your videos. When a bit is slipping in a drill chuck, one possible solution is to tighten up all three key positions. Many times, this will stop the slippage.
Hello, just a suggestion for your Mill table. I have good quality plywood cut to nest against the vise and strips to key to slots. Helps to protect the table. I have a ground table, Mill is a XLO I bought new in 1970. Table still looks new. Thanks for another good video. HAPPY NEW YEAR. George from Indiana
Hope you all had a great Xmas Steve and Co, Happy New Year for twelve hours and 32 minutes GMT. Great job on the draw bar and great to see you using the lathe and the new Do All mill. Doesn't Cora just look right at home? Lol so glad you gave her a loving new home. See you in the new year and stay safe Y'all cheers from the UK mate
What size change gear do you need? 127 tooth?, its the gold standard, evenly divisible by 5 to get 25.4, 47/37 was real common as well, but its only close, that ratio (1.27027027repeting) will get you 19.9957.... . I made one for my old 1917 Hardinge, cutting a prime number is a bit of a trick if you don't have a matching plate or a change gear for your gear cutter.. we ended up using the metric change gear from a smaller 90's jet engine lathe in a 40's Fellows high speed shaper. if your dividing head has the ability to do differential dividing (plate clamps in a big ring so you can accurately get partial holes you might get away with that. another option I considered was to spot a 127 hole bolt circle in my CNC router (Elizabeth's laser?) then drill, or drill one using the bolt circle feature of the dro.. it needs to be good, but close would be good to work for what you need.
Another great video, Steve. You have been an inspiration. I have acquired a couple clapped out machines of own because of things I’ve learned from you. I appreciate the content and the effort. You’re a good man.
The different threads in the ends signifies if it was made to a DIN or to an ISO standard, the taper is the same for NT’s BT’s & CT’s(aka cat’s) the only difference between the three holder types is the flanges. Just pointing out is it appears your mill was originally set up to run an NT40 with the ISO standard drawbar thread(if I remember right). BT’s are way more common now and easier to get second hand (thanks to older cnc’s running BT’s) so I think it’s very smart to make your machine more versatile with adapted drawbars. Also I’ve seen Bridgeport drawbars as two piece, and I’ve always wondered why besides having the ability to simply change the stud at the factory for the type of holder the spindle was expected to run… just a thought. Love the videos Steve.
Nice job Steve, always a pleasure to watch. Having the right tools to make the accessories is essential. Thanks very much for sharing. Here is wishing you and yours a very Happy New Year.
Completely understand the whole projects within projects within projects deal. Maddening. 🥳 Happy new year to you and yours, Steve. Really enjoy your craftiness. Jack of all trades. 👍
Steve this drawbar will serve you very well! FYI I always drill my press pin holes before cutting the thread to prevent it from being askew aka cattywampus ;) I learned this from my mentor over 40 years ago.
Steve, I watch your channel quite a while now and I mostly like what I see. But maybe it can even become better! So, therefore, my two cents on the matter (self employed designer and therefore machinist, for 26 years). a) These holders can be bought real cheap and real nice new from e.g. Turkey (Eroglu) I pay 30-50 euro's for a balanced to 15k r.p.m. ER collet holder). So action number one for me would be to make a decision on the future SK40 holder and buy the missing ones new. b) Probably in combination with 1); the majority of the useable holders you own is BT-40. Get rid of the rarities and go for the BT-40. Make a interface piece for the existing drawbar and Loctited it in with 640 or another tough variety and leave it on; less work for the years to come. c) When I started my shop I used everything I had lying around or I collected it at a local recycling station. With these parts and materials obtained I made my first paid jobs for customers. I soon discovered, just like you did on this job, that using unknown materials available nearby had its drawbacks'. The clients machinery I designed, and made, encountered problems later on and I had to replace the failed parts that I used NOS. NOS meant mostly that I couldn't obtain the original installed part and had to change it to a readily available part. You guessed right; not exactly the same.. So rework had to be done. I felt, and still feel, this was a pour decision on my side so I took the extra work to replace a worn or faulty part at my expense (and I kept these clients until now by doing so; don't step into the "penny wise, pound foolish trap" colleagues). Lesson to be learned; if you want to be considered a professional, act like it when you've earned the little money to do so as a starter. I soon recognized that if you want to serve your customer, or later, yourself, you have to make a plan of the work ahead and order the parts and materials you need for the job. Doing it this way; no surprises when machining (f**k this stuff is hard, weird, unexpected etc.) and a smooth flow towards the set goal of parts to be made. I know this is your own shop and it doesn't matter that much maybe rightnow, but when things start to grow, believe me here, saved time is much more valuable than saved money. So, final conclusion; repairing, customizing; all great for the globe, but maybe not the "right" economical decision when you drive a shop to make money to earn you a living. I totally understand that owning and maintaining a RUclips channel can be a different driver. If the channel is a major source of income, or you plan it to be, the decision on how you could or do stuff could differ. I'm a professional and like to connect the dots in a short straight line whenever I can though. I'm curious on your perspective here. For now happy new year and all the best for times to come, Job

Metric holder are BT40. The U.S. holders are likely NMTB40. CAT 40 has a different flange than the NMTB
It is really good to see the mill finally fully functional!
I believe the pin is there to enable you to unscrew the drawbar if the top threads loosen when trying to unscrew the drawbar. If that were to happen without the pin, you’d have the drawbar stuck in the toolholder and no easy way to remove the drawbar.

But you sent shivers done my back at 48:48 when you took a measurement with the spindle turning and your fingers that close to the spinning cutter. Just saying I enjoy your videos and would like to continue watching them. Stay safe and have a good new year.
Love these videos. Using the tool to make the new tool for the tool. You can understand why they have the tool maker profession in engineering shops. They are they people that allow us to make more stuff.
Best wishes for you and the family for 2023
Happy new year to you and your family Steve may God bless you all
Really nice work, and a very informative job. You are a talented young man. I really look forward to seeing you Saturday morning's. Have a safe new year, and see you next year.
I always like your sit down thoughts and the shop tours. The fact that you are able to take a 12 month sabatical is wonderful, it gives you the time to try out if something else will work for you, in the knowledge that there will presumably be a job for you at the end of it. To be honest I'm sure any number of companies would be glad to have you if you decide to go back to work again. This channel is the very best advert for your capabilities.
Enjoy New Zealand, I think we should have been there next year, a retirement present to ourselves, but life got in the way big time. My father went years ago and my brother went on honeymoon, thought it was fantastic. I have never been, despite spending 15 years travelling the world in the merchant navy.
I feel like this comment was meant for Stefan Gotteswinter 😉
@@bcbloc02 Apologise, you are right it was, I wondered why I couldn't see it on his channel. I shouldn't have two or more windows of YT open at the same time.
Love your videos. Have a Happy New Year. Glad to see your new OSHA approved shop doggie Cora is earning her keep, checking your work. 😄👍
Your videos are always a weekend treat!! Thanks for all the effort you put into them, Happy New Year for you and your family. Take care!!
I see Cora didn't help you with holding the other end of that shaft while you were driving that pin home. Must have fallen asleep next to the the heater again. Oh, well, good help is hard to find. Happy New Year, hope 2023 is good to all of us!
Steve have your small thread on the very end and step it up to the next larger thread and at the other end have it threaded with a nut on the top to make up for the longer and shorter draw bar just use one bar for both sizes
Hi Steve Another great video. All the very best wishers to you, Elizabeth and family for 2023.
Happy New Years to you and your Family Steve. Look forward to new videos in then new year…. Awesome channel here
Nicely done!
Awesome as Always..Great Project.
For a home use die holder even cheesy mild still would be fine!
Steve, Always watch, but never comment.. My Friend...get a power draw bar on that...The air gun type would work just fine, saves you from getting the ladder out and keeps your rotator cuff healthy. It should be retrofittable to the tooling you have, and you'll never regret having it. Awesome content! Just worry about ya.
Hey Steve , Happy new year, looking forward to all the new content.
Thanks for your videos. When a bit is slipping in a drill chuck, one possible solution is to tighten up all three key positions. Many times, this will stop the slippage.
Tightening all 3 is how you are supposed to tighten a keyed chuck..
Hello, just a suggestion for your Mill table. I have good quality plywood cut to nest against the vise and strips to key to slots. Helps to protect the table. I have a ground table, Mill is a XLO I bought new in 1970. Table still looks new. Thanks for another good video. HAPPY NEW YEAR. George from Indiana
Outstanding work. Love these type videos. Happy New Year to you and Elizabeth
have a good new year
Man's best friends, a dog and a lathe!
Hope you all had a great Xmas Steve and Co, Happy New Year for twelve hours and 32 minutes GMT. Great job on the draw bar and great to see you using the lathe and the new Do All mill. Doesn't Cora just look right at home? Lol so glad you gave her a loving new home. See you in the new year and stay safe Y'all cheers from the UK mate
What size change gear do you need? 127 tooth?, its the gold standard, evenly divisible by 5 to get 25.4, 47/37 was real common as well, but its only close, that ratio (1.27027027repeting) will get you 19.9957.... . I made one for my old 1917 Hardinge, cutting a prime number is a bit of a trick if you don't have a matching plate or a change gear for your gear cutter.. we ended up using the metric change gear from a smaller 90's jet engine lathe in a 40's Fellows high speed shaper. if your dividing head has the ability to do differential dividing (plate clamps in a big ring so you can accurately get partial holes you might get away with that. another option I considered was to spot a 127 hole bolt circle in my CNC router (Elizabeth's laser?) then drill, or drill one using the bolt circle feature of the dro.. it needs to be good, but close would be good to work for what you need.
Awesome video Steve, cheers Stuart 🇦🇺
Very. Nice work.
Another great video, Steve. You have been an inspiration. I have acquired a couple clapped out machines of own because of things I’ve learned from you. I appreciate the content and the effort. You’re a good man.
The different threads in the ends signifies if it was made to a DIN or to an ISO standard, the taper is the same for NT’s BT’s & CT’s(aka cat’s) the only difference between the three holder types is the flanges. Just pointing out is it appears your mill was originally set up to run an NT40 with the ISO standard drawbar thread(if I remember right). BT’s are way more common now and easier to get second hand (thanks to older cnc’s running BT’s) so I think it’s very smart to make your machine more versatile with adapted drawbars. Also I’ve seen Bridgeport drawbars as two piece, and I’ve always wondered why besides having the ability to simply change the stud at the factory for the type of holder the spindle was expected to run… just a thought. Love the videos Steve.
Nice job Steve, always a pleasure to watch. Having the right tools to make the accessories is essential. Thanks very much for sharing. Here is wishing you and yours a very Happy New Year.
Completely understand the whole projects within projects within projects deal. Maddening.
🥳 Happy new year to you and yours, Steve. Really enjoy your craftiness. Jack of all trades. 👍
Steve this drawbar will serve you very well! FYI I always drill my press pin holes before cutting the thread to prevent it from being askew aka cattywampus ;)
I learned this from my mentor over 40 years ago.
Enjoyed watching you make the new drawbar. I hope you and Elizabeth have a Happy and Prosperous New Year.
I need to make the exact same thing for my mill. Mine uses a 30 taper though.
Its good to see your dog is very helpful just like mine.
Joe
Happy New Year Steve , really enjoy you channel thank you for all the hard work
Nice work on the new drawbar(s), Steve. Great reverse engineering, also. Happy New Year to you, Elizabeth, Cora, and your family.
Thanks Ron, I appreciate you buddy. Happy new year
Well done 👍
Watching you on new years eve having a whiskey, great video mate as always happy new year to you and yours. Cheers
What a great way to end the year watching a happy Steve machining, A very Happy New Year to all your family and viewers for 2023 from the UK.
Steve, I watch your channel quite a while now and I mostly like what I see. But maybe it can even become better! So, therefore, my two cents on the matter (self employed designer and therefore machinist, for 26 years). a) These holders can be bought real cheap and real nice new from e.g. Turkey (Eroglu) I pay 30-50 euro's for a balanced to 15k r.p.m. ER collet holder). So action number one for me would be to make a decision on the future SK40 holder and buy the missing ones new. b) Probably in combination with 1); the majority of the useable holders you own is BT-40. Get rid of the rarities and go for the BT-40. Make a interface piece for the existing drawbar and Loctited it in with 640 or another tough variety and leave it on; less work for the years to come. c) When I started my shop I used everything I had lying around or I collected it at a local recycling station. With these parts and materials obtained I made my first paid jobs for customers. I soon discovered, just like you did on this job, that using unknown materials available nearby had its drawbacks'. The clients machinery I designed, and made, encountered problems later on and I had to replace the failed parts that I used NOS. NOS meant mostly that I couldn't obtain the original installed part and had to change it to a readily available part. You guessed right; not exactly the same.. So rework had to be done. I felt, and still feel, this was a pour decision on my side so I took the extra work to replace a worn or faulty part at my expense (and I kept these clients until now by doing so; don't step into the "penny wise, pound foolish trap" colleagues). Lesson to be learned; if you want to be considered a professional, act like it when you've earned the little money to do so as a starter. I soon recognized that if you want to serve your customer, or later, yourself, you have to make a plan of the work ahead and order the parts and materials you need for the job. Doing it this way; no surprises when machining (f**k this stuff is hard, weird, unexpected etc.) and a smooth flow towards the set goal of parts to be made. I know this is your own shop and it doesn't matter that much maybe rightnow, but when things start to grow, believe me here, saved time is much more valuable than saved money. So, final conclusion; repairing, customizing; all great for the globe, but maybe not the "right" economical decision when you drive a shop to make money to earn you a living. I totally understand that owning and maintaining a RUclips channel can be a different driver. If the channel is a major source of income, or you plan it to be, the decision on how you could or do stuff could differ. I'm a professional and like to connect the dots in a short straight line whenever I can though. I'm curious on your perspective here. For now happy new year and all the best for times to come, Job
