Video

hi thanks for the video i have 2 solar panels in series( so 2x 36 volt dc =72 dc volts right now going to my inverter) i like to add only one more solar panel in parallel to the other 2 what would be the result voltage as far as you know thanks

Thanks, man! Great video! I just ordered my mini-lathe. I'm looking forward to getting it all setup. I will be saving this video. Thanks again.

I didnt know Noam Chomsky was interested in fiddling with stuff, amazing!

Is this thing waterproof?

What about the cheap plastic gears inside the mill?

Nice info, can we use wood file with T6061 ? kind regards

The key thing is that your new brushless motor has a hall sensor in it (the motor controller can track the position of the rotor). So where you slow the speed of your old brushed, DC motor you do that by decreasing the total power to the motor. The brushless controller, with the help of the hall sensors, can increase voltage and amperage to ensure the motor keeps spinning at the same slow speed when under load. So you get close to full power at all speeds.

What’s with the run out at the top of the spindle, and the worm shaft where it connects to your x axis drive. Is something bent? Mi Micro Mark mini mill, which looks similar to yours doesn’t have this. You have some very nice ideas for upgrades.

Nice wow

For cutting aluminium, try rubbing alcohol instead for cutting oil!

Amazing!! the last one i saw was in 1994 in são paulo, Brazil. the Next one here will be in 2045!!

I wouldn’t think that MDF, being so soft, would provide adequate rigidity for a lathe support.

Really enjoyed this series, came out great.

Awesome uogrades. Considering buying this from HF and love the insight before buying. Thank you.

nice work

awesoem upgrade! i think your spindle bearings are goig out

Hi there! I recently got a stiriling engine and what type of alchohol should i use in the burner

Beautifully done, including the recovery from the mishap with the collet. I don't have the space for a mill or lathe anymore, so I was thinking of trying to make a base in a form something like yours in Shapelock (polycaprolactone) or hardwood.

For 28:59 on your emergency stop button couldn't you put a relay in that once you press the emergency stop button a second time it just completely recycles the power to the unit bypassing the need to rotate the knob back to zero? It would be like resetting the circuit it so the emergency mode is deactivated that way you don't have to turn the knob back to your original speed setting. Or another option just unplug the entire unit and plug it back in to do the same thing

👍

Well now I want one

Might be fun to make a chiming clock, thr slider could hit a gong. How about a ships clock, runs on 8 hour watch cycles, not 12.

That was cool. Thanks

Hi Guy question on the table motor controler what is the power input to the controler /.I would like to get a little information on that . did you use a transformer to supply it ? . Thats not stright 115 volts ac right? thanks paul

A very cool clock!!!

Great fun.

Awesome!

good! 👍

Can you believe there's another Pulsar Clock Video just released by World Science Festival right before your video on my CZcams video? I swear CZcams serendipity is REAL!

I've always just used the side of my tool post.

Hi, professional machinist here, great video! Thanks for showing us the tach! I want to add one to my mill, because it's faster than the dial shows. SAFETY MESSAGE: NEVER spin up a 3 jaw scroll chuck without gripping something in the jaws! They can spin out on their own, and become DANGEROUS PROJECTILES! Cheers! 😁

Good stuff, you have a thumbs up from me. Cheers

Thanks for the video & inspiration. I bought a mill last year which had a 2 axis DRO on the X & Y & a small mag scale reader like the yours on the Z. I saw a great price on Ali Ex on a 3 axis of the same brand on my mill & got it w/ the intent of moving the 2 axis to my lathe. Figured the mag reader would go in spare parts, but now I see I might be able to put it to use on the lathe's tail stock. 'Might' is the operant word, tho, since my lathe is a hopped up Sherline I built. I'm gonna have even less real estate to work w/ than you did! You're a braver man than I splicing that USB cable; I've nothing but headaches & failures attempting to splice those small cables. I get 'em done, have 0 ohm readings, correct connections, color-wise, all looks good, then the dang thing has problems when powered up. I finally gave up trying & figure out a way to manage a coil of excess cable, instead. But, seeing a USB plug inside, this may be the perfect place for 1 of the (worthless), 6" USB charge cable which seem to be packed w/ every rechargable device I buy, nowadays. Re: tailstock lock lever hitting DRO Thicker washer might fix the prob by indexing the handle CCW a bit. I keep flat pieces of clam shell plastic around for fitting something like that. There's enough vatiation in thickness from different packages to have a decent range of sizes. Stamp out a few washers & shim 'er up. In low torque situations, the plastic may be all you need; it's plenty tough. GeoD Oh, yeah, when I end up w/ a "oooh, that's too close to the edge" situations, I go the belt & suspenders route & add some adhesive to the fastener joint to eliminate stress which will get the fastener started towards coming loose. I use the belt & suspenders approach to most fastener joints when I get sub 6-xx & even w/ 6-xx, sometimes. It's too easy to over torque that little stuff & I find lock washers can't get the job alone, in many situations. I keep some 60 sec epoxy, (HF), around for this, as well as a good urethane adhesive. Plus, I'm a big fan of the black tire repair isocryanate RV'rs use to repair rubber tires. It's thick & seems to have some resilience std iso doesn't have. Happy fixing & making...

Hello Guy. I noticed that when you spun up the motor for the first time on the machine, there was a LOT of runout in the pulley that you made. This is quite bad for the belt. Have you noticed any issues since you started running it with this modification?

Still waiting for my new lathe to be delivered to trying to learn as much as I can thank you for the info sir

can you briefly explain why we have to turn the potentiometer down and then back up? my lathe works like that...its kinda annoying.

What a cool idea... How about opposing permanent magnets to keep it floating in the middle with no power, then use +/- electromagnet current to adjust the height?

Since most mini-mill owners never tilt the column, you might consider fixing it permanently at 90*. It will improve rigidity. Also the big pivot bolt actually compresses the hollow column so alleviating that would also improve stiffness.

Outstanding job

I found you because of your giant plasma lamp in catskills ny at the emerson kaleidoscope. Love your work!

question. I have an existing setup with 19 405W Q-cell panels and iQ8+ inverters. I believe they are strung together with one line having 9 and the other having 10. I'm thinking of adding 4 more panels to the back of my attached garage (maxing out my south facing roof space). It would be easier to run a separate line for the 4 panels into my combiner box. It would be easier than adding them to the other 2 existing lines. I assume since they'll all be producing 240V AC there shouldn't be any issue doing it this way?

thank you very much!

could you do this to counter revolutions? and reset im looking to do something similar but to count feet of line

THE MOTOR WHERE AND HOW MUCH IS THE COST

Good to see someone else who likes information. My favourite electronic tool is the oscilloscope because it lets you see the invisible and the insanely fast!

Sent a like your way. Nice conversion.

Thanks Guy! I acquired a Harbor Freight Mini Mill and I am going to attempt to tram it in in the near future and you have shown me how to do it.

A nice conversion. It's a pity that that motor does not have a reverse mode. Not a surprise as people rarely drive their motor bikes in reverse. Still useful for tapping and so on. People don't understand just how fast that an electric motor can be stopped. Thanks for showing them. This is even more impressive when done on a massive mill with a huge cutter. Hit the e-stop and that tool just stops. In fact, the same thing with a lathe, you have to be careful not to stop too fast, spitting a rotating part out of a lathe can be a bit exciting. The one thing that I would think about doing is adding a third support standoff to the bottom plate, that should cut some of your noise.

Thanks for the info, nice job by the way!
