This is a very good build - getting the carriage lever to work on my Bantam was the best decision. Just one minor issue: by default 'on' should be pulled 'up' with the fail safe (gravity) turning the machine off in the down position so any failure in the mechanism will not unintentionally start the lathe. This is a convention across many industries - eg dropping something on a gas or water lever valve will shut them off if correctly fitted.

Very clever! One thing I'd like to point out though; As already mentioned, UP should be on and DOWN should be off, for safety reasons. Likewise the speed control integrated into that lever is a very clever trick, although I'd have concerns about one thing: If the speed must be very low (Very unbalanced Part/not super great workholding/etc.) and the lever accidentally goes down, it would go into full speed. That could potentially be catastrophic. Remaking the "clicky" part mirrored to have the lever be UP in the ON position would solve both problems. Again, other than that - Great Idea and execution!

You never worked on real lathe? Up = on is total counter intuitive. And integreting the speed control into the lever is not clever, its a bad idea, because of the exact reason you already mention. On industrial lathes with the speed control in the lever its down= conterclockwise (forward), middle = off, up = clockwise (reverse) and twisting for speed control

@WeCanDoThatBetter Жыл бұрын
Thanks for your comment and feedback! Yes, some mentioned the concerns about the direction the lever starts the spindle. I copied this from other machines. Almost every full size lathe works like the mechanism I built. Down starts the spindle right and on some lathes up starts the spindle in reverse (left). For me this is very intuitive and convenient although for ultimate safety reasons that should be different, you're right. To prevent the spindle from accidental start I built the locking mechanism in the off position. That's something I also copied from the full size models. If something drops on the lever, it is expected to stay in off position and not start the machine. The speed control is more a nice gimmic as it was already built in the sewing machine pedal switch. I use the lever normally at full amplitude with spindle at full speed according to the max speed set on the controler. But to quickly lower the spindle speed for a last chamferring operation on your part without having to programm a lower speed on the controler, I think it's great. But you're right, there is the risk of accidentally dropping the lever down and ramping at full speed. We'll see how usefull it is. Definitely the new lever should be much safer than the pedal switch bolted to the spindle casting. The video told you how dangerous it was... Happy to still have all fingers and no hole in my head! Thanks for your input :)

As the original switch was already a lever type thing that worked together perfectly. Off course the magnet and sensor has to be somewhat protected from metal chips.

Haste wieder gut gemacht. Bei einigen Aktionen standen mir allerdings die Haare hoch. Deinen C 45 hättest du nicht härten müssen. Der ist von haus aus sehr fest und hält den belastungen in deiner Drehbank locker stand. Härten mach immer in Öl, da bist du auf der sicheren Seite, vorwärmen auf 60-70°C. Normalisieren vor dem härten ist auch ne Option. Noch n tip: Um ein Gefühl zu bekommen, wie hart oder zäh Stahl ist, mach mal folgendes: Besorg dir 3 stück 8mm dicken Rundstahl in 30cm länge. Einmal S235, einmal S355 und einmal C45. Spann jeweils die enden in den Schraubstock und versuche die zu biegen. Dann verstehst du plötzlich die 3 Kohlenstoffgehalte und die Festigkeit im Zusammenhang. 0,09%, und 0,22% und 0,45% machen einen RIESEN Unterschied. Ab S355 beisst du dir definitiv die Zähne aus. Hatte ich gerade letzte Woche....wollte einem Werkzeug einen etwas grössen Winkel geben....stand am schluss mit beiden Füssen an der Werkbank und hab gezogen...der S355 hat mir gepflegt mal den Finger gezeigt. :--D

Bezüglich härten: da bin ich erst draufgekommen, nachdem das Teil nach ein paar Tagen im Testbetrieb schon leichte Einlaufspuren bekommen hat, an der Stelle, an der der 4mm Zylinderstift auf der Stopperkulisse schleift. Das hat mich auch sehr erstaunt. Hatte nicht erwartet, dass die Belastung so groß ist. Allerdings ist der 4mm Stift auch gehärtet und die Federspannung ist nicht ganz sachte. Weil ich mich nicht nach ein paar Wochen ärgen wollte, dass das Teil schon ausgenudelt ist, bin ich aufs härten gekommen. Dummerweise hab ich zu C45 in den Messerforen und Datenblättern, die mir Google vorgeschlagen hat, nur vom Wasserhärten als Mittel der Wahl gelesen. Und mein Hirn hab ich nach dem ersten Fehlversuch auch nicht eingeschaltet und bin auf Öl umgestiegen, hab mit dem Härten an sich auch leider keine Erfahrung... :) Deswegen danke für den Hinweis, nächstes Mal werde ichs mit Öl versuchen.

Damn, that chuck key dinged those ways for sure... Glad you got away from it with all your parts intact, but i lament the lathe nonetheless... To avoid cracks, normalize the parts first, run them once without quench, letting them cook for a while(argon purge would be marvelous for that), and then harden them... Machining can focus the already present stress in the metal and cause its own stress points and lines... Normalization either removes or greatly reduces those... And if steel warps during normalization, it would have done so had you just tried hardening it, so its no problem that was avoidable, and after normalization, there wont be further warping during the second heat treat... So you can rough machine the parts, normalize them, finish machine them to spec and harden them, warping should be absolutely minimal, enough that it will not interfere with anything rougher than an h7 fit... And nothing a bit of abrasive work wont solve, turn a custom lapping rod and work the warping outta holes with a hand drill, it will save the lathe a lot of disgusting abrasives and will allow you to vary the speed of lapping and give you amazing feedback as you have both parts in your hands and feel any resistance(defects) that the lap encounters...

@WeCanDoThatBetter Жыл бұрын
Thanks for your comment! Yes some others suggested that too. From the safety standpoint that would be the ultimative best I guess. However my built is inspired by how it's done on most full size lathes. Pushing the lever down starts the spindle on almost every lathe with such a lever. That is very common and intuitive as the spindle starts in the same direction as the lever goes. Some lathes run the spindle in reverse when the lever is pulled upwards. There is a safety lock built in as you see in the end of the video. The lever is locked in off position and has to be pushed to the right before you can push it down and start the spindle. If something drops on the lever it doesn't move because of that locking mechanism. I hope that is safe enough :)

Interesting project. I'm looking at it and thinking it wouldn't take a whole lot to modify what you've built to also tug on a cable operated spindle brake when the levers raised past the off position. It would only take a stubby arm added to the hex rod, and a leather brake band type setup somewhere on the spindle, or maybe a setup like one side of bicycles "V brakes" and a profiled rubber block to rub against the spindle....... It would be totally unneccecery on a hobby lathe, but it would still be a pretty cool addon. :)

The controller he's using has an adjustable rate brake that may be able to function as a lock. I have the same drive but haven't gotten around to trying to create a lock signal. I use the brake set at 1 out of 5 on intensity so it just takes the coasting out. When at 5 it's slamming on the brake. A mechanical brake is still an option.
@WeCanDoThatBetter Жыл бұрын
As RJM said, you can set a electrical brake at the controller. At the moment I set it to off as it is relatively harsh even at 1 from 5 intensity ratings. But it's probably better to enable the brake again as it stops the spindle really fast in case of emergency. A mechanical brake would be usefull for cutting keyways or things like that. Here I need a solution to lock the spindle.

Ah.. and were is the head-stock brake? Anyway, the emergency On-Off button should be uses more often to prevent those little 'awakenings'... Install movable limit switch(es) when you do the brake. Me.. I'm installing a CNC conversion, but going to try to keep the manual function available.

I’d just like to make an important point here. If you’re going to copy the idea of rounding a part in the mill using the method he did, manually rotating the part - NEVER rotate the part so that the rotation can pull the part into the bit. ALWAYS rotate the part against the rotation the way he did. Otherwise the part and whatever you use to hold it with will be grabbed out of your hand and violently and rapidly spun around. It may hit the mill column where the handle/clamp will fly off, possibly right at you. Or it will miss the column and spring around into your hand which you won’t have had time to move out of the way. I don’t approve in doing this because of the danger. Metal isn’t wood.
@MrJake-yx8ll5 ай бұрын
100% agree. Good safety comment That was a true cringe moment. I would recommend editing the video and completely eliminating that section to not give anyone ideas. This is also a reason why I'm not an avid woodworker. I do not like the idea of holding work being cut with my hands. I prefer Chucks, clamps, vices etc. to hold the word piece and metal machine components to feed the cutters--not my hands❤

Really nice work. Your obviously running a VFD with RS485 interfacing - why bother with the electro mechanical switchgear that you made? A discrete 24v FWD/OFF/REV with pot driven speed control on the apron is far easier and more convenient(albeit both options are.vast overkill on an 18" screw cutting lathe). BTW Carriage mounted motor control was only popularly adopted(1960s).when discrete electronics. we're not available and manufacturer's wanted to do away with expensive mechanical clutches... Don't get stuck in the perception trap ie. trapped by old thinking/ technologies. Even better, try a footpeddle control - intuitive and natural in feel... and with emergency stop functionality too!

Nice! Just like a big lathe. Did you put your threading dial in a different spot?
@WeCanDoThatBetter Жыл бұрын
Thank you! My lathe didn't have a threading dial. I think in the metric world it isn't so useful, but I didn't really understand how it works so far. Perhaps some day I need one and have to find a place to mount. But at the moment I have something different in mind for threading which should make a threading dial unneccessary.
@backyardmachinist Жыл бұрын
@@WeCanDoThatBetter Nice. I didn't know that about metric threading. Looking forward to what you come up with. Cheers
@wolf310ii Жыл бұрын
@@WeCanDoThatBetter The threading dial has nothing to do with metric or inch. If you cut a thread with a different pitch than the lead screw (on these small lathes usually 2mm) you need the dial to find the correct position to close the lead screw lock, if you open the lock to move the slide back. If you close the lock on the wrong position, you cut a double thread. On short threads the dial isnt that usefull, on long threads its faster to use the dial. But switchig the motor constantly between forward and reverse can kill it, my boss managed to do this. Instead of using the brake or going from forward to off, to reverse, he did go from forward right into reverse until the motor said "Nope, im done". The setscrews that hold the stator in the caseing sheered off, the stator rotated in the caseing and ripped all wires off

Hi and thanks for your comment! Yes that is right. The controller for the brushless motor has a button for switching the motor direction. I'm not experienced enough with electronics and don't wanted to change everything on the controller so I decided to install a lever on the bedslide for general on/off which has only one switching direction. To change the direction in which the motor starts you have to press the button on the controller box. I hope that makes some sense to you. I made a video on the brushless motor and controller where the direction change is explained.
