Where’s the best place to pick up? Where you left off of course. Just because I got a little sidetracked by a little cross country road trip last video doesn’t mean I’ve forgotten Yee Olde Eureka tool. So let’s finish it off. And maybe we’ll even demonstrate the beautiful movement it makes on a “gear cutter” 😉

Very good project and fun to watch. You two make a very nice couple. 💞
Next up: inheritance machining brand clothes pins
Just amazing! Your video, workmanship, humor, and your wife are not nominal, precisely excellent. Thank you.
I have sold my 15 x 60 lathe to a young friend who is hoping to get out of his engineering job to begin a creative business. He is teaching himself making custom horns. The videos helped inspired him to become a machinist, creator and a special talented person. I’m proud to pass on my lathe which I love. I hope the new one replaces it will be as cool as I hope.
You do the most complicated things lol, just testing the boundary of your shop lol. You can just buy gears lol. But I get it
when I saw that pen hit the paper, all I could think was “it’s aliveeeee, it’s aliveeeeeee” Les goooo, can’t wait to see som gears
Would you be interested in matching some parts for a retro- mod engine ? Its a 1890's/1990's or 19th/21'st century engine. Design Taken after the old oilfield engines, the first diesel engines, and pony engines, hit and miss engines farmers and sawmills and tractors used. A long stroke. Large bore compared to modern engines. Im looking to cast the case from aluminum, weld the crank from pieces of round and flat bar. The camshaft made similarly using. Slices of tool steel round stock, about 3"diameter. The shaft from 1"steel with the journals pressed on. Or heat shrink them impossibly making tool to clock the lobes in time, usinga large nut with a hardened steel pin to fitin the lobe, and pivot on the shaft. Possibly having fine lines previously scribed on the the shaft. The 2-4 shafts being only 6"-8"long possibly using roller bearings. On cold rolled journals. Whole main bearing web bolting inside the crank case also holding the oil passages in them. Allowing the oil pump to i bolt to one. Feed a remote filter. Then back to a main web to feed the bearings piston rod passing the oil to the wrist pins, then squirting the piston lubing the oil rings. The smaller engine having a roughly 4" bore, while making use of a 6"-8" stroke, and possibly limited to 2800 rpm and idleat 350-400 rpm.
Using some off the shelf parts, like valves oil pump, roller lifters. Bearings the rod and main bearings possibly from a big block Chevy v8 engine with nearly 3" diameter, use one of the main bearings without the thrust bearing for the rodbearing. Aside from the thrust bearing, a set of bearing can nearly overhaul the engine twice , if it only had more thrust bearings also using common cam bearings and timming gear,
As fir the engine layout, i have several ideas, from opposed cylinder twin to flat 4boxer style. To a twin crank parallel twin. With counter rotating cranks. To change rotation of the output, just install the flywheel and output on the opposite crank. The cranks being geared together with a 2.5" wide by roughly 12" gear. To transfer the nearly 20 HP each cylinder should be capable of producing on that design, with a supercharger, but this engine needs to be way less exotic. I need a simple engibe. Used to spin a alternator to generate DC power to recharge batteries powering my offgrid home. Im hoping the engine can br fitted with heavy flywheels, operating as a hit and miss EFI engine where the valves are locked open and the fuel shut off until the RPM drops enough to require another series of power strokes, and the flywheels and compression ratio coming together to produce plenty of power for a specific load the Miss being several rotations then a hit or two. Enough of a miss, hopefully a efficiency gain is possible. I also want to build a compression ignition engine. To burn oil, used waste oils, pyrolized plastic and rubber, also looking into a hydrogen engine using water split by Electrolysis. In a similar to diesel but spark ignition engine, possibly compression ignition. Research is required. I'm looking to explode the hydrogen and harness the power a possibly 6-12 cylinder engine, with 3" bore 3" stroke possibly cinnecting. The piston to the crank by a lever. Operating like a treadle, allowing the crank to be ahead of the piston. So the ignition can happen when the crank is 20°-45° past TDC in a normal engine, allowing ignition at TDC of the piston, and not destroy the engine. This is just a idea fir now, it's not gotten far. But fireing at peak compression, whije the crank is at the optimal position for leverage. The power outout should be insane ! The fuel needs to burn fast to create instant peak pressure to use all the available power! Sorry to ramble. Have an awesome day!
One phrase: "exciting bar". Now I wonder how many items end up in the Box of Shame when you make one of those.
That demonstration with the pen and paper caused everything to fall into place. Such a simple little thing that then immediately clarifies the entirety of the last two videos. But the journey of getting there was even more enjoyable for not fully understanding it.
My takeaways from today's episode:
1. I would totally buy an "Ask me about my O.C.D." t-shirt from you.
2. You should have bronze nuts if you have an eccentric shaft.
3. You'll end up sleeping in your shop if you take up machining as a hobby.
That's some pretty nuts you got there.
Edit to add: The joy of the head engineer at watching the gear cutter be drawn out is awesome.
holy shit, thats sexy.
82* countersink? Blasphemy! You need to join the 120* cult. It's much nicer over here
Great editing on this one…absolutely love it!
Last week I had a "Thats enough machining for the week" moment. I was drilling a deep 3/16 hole in aluminum in the lathe. I wasn't clearing chips or applying cutting oil often enough and basically welded the drill inside the hole.
Very. Cool.
This is a thing of beauty. I really had no idea that these existed and it's really satisfying just to see it move. We get so complacent using CNC vs the old way of doing things that we forget the art and thought that used to go into making something manually.
Bad ass!! Thats brilliant.
Yet again, that was the most satisfying video to watch! From a happy autistic!!!
I'm not much of an engineer, but I did make my wife's wedding ring on a lathe, and even heat treaded the titanium.
don't you need to harden at least one part of the ratchet mechanism to reduce wear while using it?
That DCMT toolholder looks odd. The end of that insert is hanging out in mid-air. The toolholder should have a point to support it.
Is the middle of the journey not the best part?
Man, do your wife do some teaching on how to "wow" in a so astonishing and inspiring way !!! Well, if you ever plan on going in France, do tell me, I will defenitely buy a course or two for my sweet loving wife. No kidding, respect to you as a machinist and to your wife as a inspiration ! Be blessed for the joy of looking at your couple in action.
Question. How many of you guys who are watching this video never touched a lathe in your life? 🙋♂Don´t know why I enjoy so much machining videos 😅
I'm absolutely in LOVE. This is fantabulous. I can't wait to see chips being made to make GEARS.
On a side note, I laughed 😂 so hard about the nominal explanation I almost choked. That is the best simplified definition I have ever heard. I'm using it from now on, thanks. Oh, and thanks for the great clickty clickty video (and the gratuitous parts with the great engineer, Mrs. Inheritance). As always, stay safe and watch out for flying chips.
Your grandfather would be very proud.
Do the ratchets, pawls and torsion springs not need heat treatment?
Did the crashed bit go in the box?
I'm absolutely losing my mind over that demo. THAT'S what this thing does??????
He was once bitten by a Powertool, now he is half Man half Drill: Mandril
Why is this tool driven with a drive dog instead of being clamped in the chuck? Would think a chuck would be quicker/easier/more rigid.
Super satisfying sound……
The generous measurement with the calipers explaining how they take your measurements for the mattress was on point.
Amazing. I spent the last 2 videos wondering how on earth the tool worked and that demo was phenomenal. Looking forward to the next in the gear cutter / gear making series.
As always great content 🏆
Your wife nailed it when she said "That is so cool" 👍
The human mind. What potential!
I like your wife getting excited!
Always love a good Yak shaving video
That was such a fun episode, but seriously, that entire demo from 24 minutes in is so satisfying! Like daaaaayuuuum!!!
As happens quite often, I have to agree with your wife: It is very cool! 😁
Out of interest why drill all the holes first? I can understand on the small parts because it's harder to secure the part to drill but why on the bigger parts? (Not a engineer of any means just enjoy watching this type of content)
