If your square doesn't fit in the round bar, you freely get round chamfers... because round chamfers is what separates us from round animals...

The truth about the billit pulley is that you don't spend that much time building an awesome machine, to spend the rest of your life watching a cast zinc hardware store pulley wobbling like a drunken sailor. Nailed it! ;)

So, so true.

Bend a V-belt around a pulley and the inside diameter compresses and the outside stretches. So, smaller pulleys need a different angle than larger one to match the "squish" of the belt..

Hello Scott, how are you doing😊

Another interesting property of a scotch yoke is that it provides a true sine-wave of motion. A normal crank setup is actually the sum of two waves, with one at twice the frequency as connecting rod covers slightly less vertical distance when it is angled at each left-right motion of the crankshaft. The motion approximates a sine wave, but has a few extra funny bumps in it.

Nope. It's the cord fairies who tangle up your extension cords and air hoses that you so carefully put away. They hide brushes once the cords are all messed up.

tip for a die file yoke, do not use oil as a lubricant, use graphite powder(pencil lead) the fine particles from what ever you filled aticks to the oil and messes the machine up, graphite powder does not allow any material in as its a "solid" lubricant

11:33 - oh good, I'm not the only one that brings that algorithm to the analog world. :)

You could turn the motor and die filer counter clock wise. Placing the motor behind and pulleys on the right out of the way or turn more placing the pulleys in the back. This way the filer always sits as low on the counter so you can see from above downwards on the piece your working. Which is the way die filers are used best.💡💡🤔💡💡 Making a 1 inch platform stand from 1" square tube welded and a cover guard over the belt and pulleys would be the icing on the cake. 🎂🎂🎂🎂🎂🎂🎂🎂🎂🎂

Not a "metalologist"? Who else would have one of those tubes to look through and determine whether a bar is regular or fancy steel? Great episode, Quinn. Thanks,

Brilliant training Quinn! After fooling around with lathes, a shaper and a mill-drill for 45 years, I have learnt more from you in 6 episodes.

Thanks for the tip about cutting keyways! Since I upgraded my tubing roller, all my old drive wheels need keyways cut into them. Broaching is expensive and complicated. That lathe technique is something I can do with what I have. Thanks Quinn!

Hello, how are you doing😊

I appreciate how you adapt to small issues or mistakes and come out with a solution that works for your needs. This sets such a great example for times when variables sneak in to create havoc. Great stuff!

I think this is the same kit someone at our maker space made a few years ago, prob longer then that, but we just moved the motor to a new mount and table set up with the motor below the rest of the unit. HUGE diff is workable space. It allows us to move around the whole unit easier and not have to work our bodies or projects around the unit. Did not change anything else, and it was worth the extra work. Also, one of the guys made a piston that holds a small saw blade and you can use it to saw metal now in fun shapes.

Hey Quinn. Your videos are great in all aspects. Also, you're really pleasant and oddly relaxing to listen to😊

Clamps like a champ!

I LOVE ALL THE KIT BUILDS !!!! obsessed

If you are in a hurry to make something round you can just hold it against the 4 jaw with the jaws loose with the live center of the tailstock placed in the center drill hole then tighten the jaws. Thanks very much for the slitting saw tips. I have been buggering things up with them since for ever taking light cuts.

It's a bit more work, but you cold drill the hole first, slit it, then come back and clearance drill it. Best of both worlds.

Hi Quinn, a cogged v-belt may be better for that application may be better, they draw less hp. Rich

Hi Blondi great progress. recently I installed a vevor servo sewing machine motor on our juki industrial sewing machine. now instead of 0 rpm or terrifyingly fast , it is controllable from a slow crawl up to full speed. control is still throught the treadle. Have you considered variable speed ,by foot pedal for the filing machine? amusingly I didn't even know these motors existed until a watched a youtuber install one on his 7" minilathe.

The drive shaft needs a better oil seal as mine leaks oil. I much enjoyed making mine.

Oh, that pulley going onto the shaft made such a satisfying sound!

That mild steel is for the table supports but I imagine you probably figured that out by now.

@Blondihacks

Жыл бұрын

Sure did. 😄

I do the slot second, but. Hope, tap, counterbore. Don't drill the clearance. Then slot, then drill the clearance. Clearance over a tapped hole is a light cut, so no need to support the slot.

I have always been very hard on my self when making errors. Presumably the way I grew up. After watching yor showing mistakes - and gracefully recover from them, I am starting to be more forgiving with my own mistakes. This is also true for other YT'bers who like you show errors and mistakes. That's the way we learn. As always great content.

Quinn, your videos are such a pleasure to watch. I really look forward to my Sunday mornings with coffee. Thanks

Years watching this channel and idk why but just now as I watch the 13:51 mark it dawn on me just how actually small hobby milling machine really is.

Oh my goodness-I saw your metals hardness tester and told my wife I wanted one. Then I looked it up on the Web and saw its price. I'll keep using scrap metals and just hope for the best.

Such an interesting episode. Thank you as always for sharing. 👏👏👍😀

Good technique on the slitting saw/clamp bolt order of operations. Thanks.

You can put a small bronze bearing in the block.

Thank you for showing us the scotch yoke Quinn, this actually gave me some ideas and a possible solution to get a drive motor to operate a piston pump. If it works, it could potentially save me several headaches and money

I had never even considered the grub screw on top of the key trick, that sounds like a great idea!

Very nice job. Something I have seen done on pulleys with little or no collar shoulder is instead of drilling and tapping the hole straight down from the top at 90° to the shaft you could have drilled a hole on an angle of about 30° from the face of the pulley about 3/4" above the bore. This should let the set screw still seat against the woodruff key and also lock the pulley since you are using a woodruff key the key would rotate in the shaft seat slightly to jam against the keyway slot in the pulley. Doing the threaded hole this way would take a bit less time since you would be removing less material in the pulley and the time needed to tap the thread would be less. Just a thought

I wonder if the casting for that yoke would be more aerodynamic in reverse 😊

The deeper groove will make less likely the belt pops off😉🙂

What amazes me is how you have all the proper tools and know how to use them! Just fascinating!

Thank You!

That yoke casting looks like they reused a mold they used for making adorable models of 30s Ford pickups.

The belt doesn’t bend perfectly, there will always be regions where the belt is in tension because of the bend, and regions where it is in compression. The tighter the radius of the bend the more pronounced this is, and the more the belt under compression wants to schmoosh out. Therefore; although the belt is nominally the same cross section throughout; the angle (and linear dimensions) change depending on the radius of a curve.

A segmented vee belt is adjustable in length and eliminates possible vibration...nice on a variety of tools and machines...

The scotch yoke is a useful piece of engineering to use in Lego Technics because everything's built out of right angles and standard distances, put two long bricks next to each other with a one stud space between them and you've made a very nice straight parallel slot, and a pin on an axle will run in that quite comfortably.

Love it! I really enjoy your videos.

I learn a lot from your work. Thank you~~

Can the motor be upside down? If so, you could mount it directly under, on the same piece of material, maybe on a longer board that could be clamped to the end of a bench and moved/removed as needed...? or with some pole/pegs on one edge that could be dropped into a couple of retaining sleeves on the end of a bench
