I was a little kid when my dad got a collection of early eighties remote control cars. I used to hide under my bed with a screwdriver and take them apart to fix them... because, you know, they had no batteries.
Looking back, I've been doing that to whatever crossed my way for a long time - except that 'under the bed' thing... I don't do that anymore - and I'm finally starting to get a grasp on how some things work and actually get them fixed.

How a Solid Tool Post Mount changed my lathe
มุมมอง 154Kปีที่แล้ว
Parting or cutting off steel has always been a challenge on my lathe. Issues range from heavy chatter to broken inserts and tools which end up stalling the motor and sometimes damaging the work done on a part. Today we're making a solid tool post mount to replace the compound (top slide). The compound on small lathes is known to have rigidity issues and that's what we're looking to upgrade. Too...

Machining an ER32 collet chuck

Today we are machining an ER32 collet. This tool will help press fitting thin long rods in a shop press. The collet chuck will be fitted to the end of the piston and there's a jig on the press plate to keep things repeatedly in place (and square). The chuck has no through hole as the the bottom of the ER taper will be pushing the rods down, not the collet. Tools I use: www.nbrworks.com/tools/ 0...

New HBM 250 x 550 metal lathe: Unboxing and Dismantling
Excellent video. Thank you. I will be doing the same for my lathe at some stage. I like your design.
Whats the name of that spray paint finish, it looks so good
Hi, it's Wrinkle Plus from VHT, there's a black version and a red one. I've added a direct link in the description of this video if you want to have a look.
Biggest downside of overcenter is that it has to go... over center to switch. I didn't think of it at first either but as soon as you did the thread I knew right away that it was the problem because This Old Tony taught me everything there is to know about overcenter. 😉
I stopped at 20sec (I will finish it) but you should've indexed from the cylinder bore (using shims under the base) before the first decking.
I indexed it from the bore 😉
@@nbrworks Maybe "the top" of the bore, but if you indicated the entire cylinder (both concentrically and along the z-axis) there'd be no geometric way the ends wouldn't come out parallel. This is exactly what you did when you used the mandrel in the lathe. The central axis was both concentric to and parallel w/ the turning center. You then created a flat base with perpendicular cuts to the flanged surfaces. This is what putting shims under the base and decking the top would do. Flipping the piece over and finishing is just a continuation of this.
That was my first approach. With the carb on the mill and a coaxil indicator, running up and down the bore, trying to make it square to the spindle. It works. It also takes a long time until it's right. The bores are not 100% perfect and indicating/averaging them takes time. Since I have a few carbs, I tought the tool was worth it. Now I can chuck any carb and recut the faces in 5/10 minutes, maybe less when I do them in batches. Your idea works, and if I only had 2 carbs to reface, that's how I would've done it.
@@nbrworks My issue was just with how you presented the problem. At 0:11 you say "the problem is, you have to use one of the flanges as the reference for the first cut". I was trying to clarify this is _not_ the case. Hence, why my first reply stated I made it only 20sec in before needing to comment. I would agree with time saving for multiples. I have no issues w/ the mandrel you made, I think it came out great and I love making fixtures/jigs. You still get a sub from me, though ;)
Yes, I got it, the way I said it made it sound like the problem was referrencing the first flange. Never thought that could sound like that, my bad. Thanks for pointing that out and of course, for joining the channel group!
You could also just make a telescoping tool with two opposing cones that grip the bore at either end. That would mean a bit les contact surface for grip and that you wouldn't have full access to face the flanges, but it doesn't take much load to turn aluminum anyway.
OMG, every frikkin time the tap snaps off, it makes me want to jump out a window. And of course it seems to always happen on the last hole..
Good video. Enjoyed it. Props for showing your mistakes - sign of a good teacher. Sub'd.
Thanks! Welcome!
What type of grinder are you using?
Hi. It's U3 'universal grinder' from HBM-Machines. I believe the current version is the U5.
Hi, Fred Fowler here. Nice videos! I was the owner of Fowler Tools and I am happy to see you using some of our instruments like the NSK Mechanical digit mics and Bowers bore gages in your work. Quality work!
Hi Fred. That's very cool, I wonder how this video was suggested to you. The Fowler/NSK micrometers are my go to mics. I have 3 of them, 0-75mm, all bought in second hand and clean/rebuilt by me. They're accurate, reliable and I trust them. I also like how they feel in the hand, they're well balanced. The mechanical digits are nice to show measurements for the camera. As for the Bowers internal micrometer, it was given to me by a family member, who didn't understand how it worked (out of calibration). I just wished it was smaller, I would use it a lot more! Thanks for stopping by and the comment - amazing what the internet can do 🙂
@@nbrworks Thanks for responding! As I am a machinist at heart, I follow a number of channels on YT like Old Tony, Abom, Clough, CEE, etc... - Yours happily popped up on my feed one day and I took an immediate interest! Back in the 80's, I interned at a number of precision instrument manufacturer's like Trimos, Sylvac and Wyler in Switzerland and Bowers, British Indicator (Verdict) in the UK. It was part of learning the business from the ground up. No better way to learn the tools than to make them! Now that I'm retired and sold the tool business, I run a small woodworking & CNC shop doing odd jobs to keep busy and I have access to a metalworking shop as well. I also stay involved with Fowler in a limited way and keep up on the industry trends. Pleasure to meet you and I look forward to future content, keep up the great work! F
I do threads up to shoulders all the time and have found the easiest way is to use a left hand tool upside down and run in reverse. I set a carriage stop that I can return to on each pass. The depth of thread is easy to calculate and thus so is the depth. Of the clearance groove. The width of the groove is consistent based on the threading tool used. Since I’m not threading toward a shoulder or the chuck, the stress of the job is gone.
That wrinkle finish is so good!
You've machined a little human ! 🙃 👶
They're getting expensive so I made my own 🙃
@@nbrworks pragmatic 🧠
That's a lot too much rpm on reamer 🤦🏻♂️
AWESOME 💯💯💯
Hey, at least you're making custom fixtures for something you plan to do more than once...
The shaft hole needs to be bored, the reamer will follow the hole and drilling is not good enough.
Absolutely brilliant project, also all the little extra bits were superb. Really brilliant. Thank you
Thanks Julian!
Nice work.
Nice effort but kinda a long way the wrong way. Use a geometric die head instead. Fast,and will get you closer to the shoulder.
Bravo!!
Fortunately in my shop we have a lathe wich stops going forward automatically as soon as it hits the carriage stop. Sorry for bad spelling I am Austrian and don’t know all those specific words in English 😂
Three things stand out about 4:36 #1 a loud noise. #2 change of insert was required. #3 Change of underwear highly recommended.
So many times when I watch TH-cam machining I cringe when forced to watch the makers power tapping with conventional taps, seeing you hand tapping with power taps was a nice balm on my soul.
This is something I have been going to make for my sheldon lathe for years you done a nice job and the results show it anyone can run a big lathe and take big cuts because they are so ridged with all the mass of cast iron but a 6mm cut on a mini lathe even though it was 12L14 is impressive my lath will not do it and it is larger than his taking the compound off and on when you need it isn't bad on a small lathe just a hassle but i do know from past experiences thatit is worth it from a retired machinist thanks for sharing
Thumbs up and comment after 3 minutes...man i love content like this❤😅 greetings from Germany
Thanks!
Might I ask what size lathe this is?
Hi. It's 250x550, check out my other videos. Thanks
@@nbrworks Hey thanks for the quick reply and I will.
Was wondering if it could work on PC board material. If it could etch/engrave copper clad, it would work great for making circuit boards. IDK but will find out with our new one we received...
Love you grinding machine. Where did you get it? Who makes it? It notes nice.
Hi, it's from HBM, from the same place where I got the lathe. Look up for U3 universal grinder, that's the one. I believe the latest model is the U5, I don't know which upgrades it has, if any.
Did you try taking the bore to size after the threading operation?
Very nice but over complicated.👍
Wow that was a fantastic demonstration and I learned a lot. With regard to the broken tap, perhaps you could have backed it off on a regular basis to break the chip, swarf, that is the way I was taught but you know a lot more about this than myself? Great save however. Subbed.
why reinvent the wheel?? just use an acorn die in the tail stock
Excellent process and work. Kudos on the removal of the broken tap! Any chance you have a drawing/ dimensions for this? I didn't see one mentioned. Thanks for the great video. Subscribed based on this.
Amazing work. good skills.

Great job! Thanks for the video.
My butt quivered watching you cut that piece on the bandsaw.
Wow, I love that tool!
Cool design. Never seen that before. Using a bi-stable pair of springs instead of an over-center design would get the same result for keeping the mechanism locked.
well done mate
Nice
Really great video and keep up the cleaning. Awesome little tool!!!
Nicely done
You are very skilled. I wish machining was a cheaper hobby.
👍👍👍 good tips and tricks
Great work. We shared this video on our homemade tool forum last week 😎
That's an awesome parting tool holdet! Well done sir. I may have to attempt making one.
Cool. Let me know how it goes. Nowadays I mostly use carbide to part off steel, but was this tool holder that taught me how much pressure and speed I should use. It helped developing that feel and confidence needed for the parting operation.
@nbrworks I hate parting. A little too much feed and chink, there goes your carbide insert. Not enough and you are just rubbing the workpiece and not cutting. I wish there were unicorn settings for speeds and feeds that would always work. I love how your setup incorporates the spring up in the nose of the holder. Just elegant. Great work!
Awesome tool good luck
ugh! how much is a lathe in this size that _doesnt_ require a rebuild straight out of the box 😵💫
