That dad has a zeal for life and invited his son along for the ride, lucky kid
Thank goodness the son was smart enough to listen....
Great to be able to build an engine with your dad. Great video for the armchair machinist.
Congratulations on becoming a Dad. Best thing I ever did. Good job on the wrist pin buttons, can`t wait to see what you make once you learn the CNC lathe.
When building a stroker, I use a medium size zip tie that measures .060 to check clearance. If any part hits the zip tie mark it and clearance. The zip tie being plastic won’t damage or mark up any components.
Also make two revolutions to double check the cam lobes clear everything with the same clearance.
Love the show and learning as you go is the way to go 😊
I use .080” thick whipper snipper cord. It’s round and easy to use. 👍🇦🇺
@@bigal878 I never thought of using weed whipper chord but ya, probably would be cheaper than my Panduit zip ties 👍😅
@@jonhodges5344 it’s cheap and in my opinion easier to work with than a zip tie due to the whipper snipper cord being round and bends easier.
i know absolutely nothing about machining but this is my favorite channel..
the “no dicking around” (1:31) is the best
approach to any problem..
agree
Thanks for the walk-through of conversational programming.
Maybe get a tray that mounts under the engine so dropped tools and bearing shells don't hit the floor, but land in the tray?
Good idea. Could even cut a piece of thin rubber to put in tray to help soften the drop
My son and I built a CNC plasma table. The hardest part for me was learning the cad program. (I am 65 ) luckily I have a younger brother that deals with that stuff every day. Cool new machine I’m sure you’ll learn it just fine.
Turn the deck towards you it'll be much easier to catch the buttons.
Also, turn the deck towards you when installing the pistons. Don't bend down to install the rod caps. Save your back!
I love the button tool . Sell kits! 4 button's,2 springs!
Those wrist pin buttons are Excellent!!!
Just a suggestion…You can use just the grooving tool to rough, finish and part off that part.
If you use a indexable parting tool, make sure you use an insert made for aluminum. They tend to be ground and have sharp edges rather than molded. You’ll get a much nicer finish when cutting Delrin.
Just use the grooving cycle and have it start at the face of the part, then work the tool using plunge moves starting from the .O.D. Once you’re done roughing, use the same tool to profile the O.D. Once you’re done with finish pass on the O.D use the same tool to part it off. It’s very easy…
I did this at one point, but the grooving insert seems to chatter on the finish pass. Seemed quicker to rough it w/ the other turning insert like shown & produced a better finish. With some time to experiment and tweak I’m sure I could get it.
Thanks for the advice!
Thanks for an amazing video on making your tool with the cnc machine.
It was most interesting following you along on the process and seeing how your new machine works.
Can’t really say I understand all you are doing but follow the basics. You do great with your new machine. Nice work.
Congratulations on the new baby girl. Just wonderful!!!! Enjoy!!!!!
I am new to this channel but have really been enjoying it. Thanks for everything.
Take care and be safe.

I have worked with CNC machines now for almost 15 years, no HAAS machines though but Mori Seiki/DMG Mori for example. I work as a machinist and programmer for a company which makes all kinda stuff for customers. Working with these machines is great, always ways to learn something new 👍🏻
Congrats to the new Maschine. I worked daily on one of these Haas TL2 for more than 10 Years. No CAD/CAM, only G-Code programming directly on the Maschine. Greetings from Germany
is it a fanuc control
No, the control is Made by Haas directly.
Congrats again to the JamSi family of the new daughter/grand daughter!!! I am 39 and a grandpa and absolutely love it!! One spoiled boy!! Lol.
You're fortunate. My first daughter was born when I was 41! Being old dad has its upsides, but now at 52, I am so damn tired 😂
Very cool, i love seeing you embracing the digital machining Area too. You now have the best of both worlds. Thanks for your content, one of my favourites at the moment. Keep doing what you do!
Wow that's cool to watch the buttons being pushed, seeing the machine interpret the program and make the part. For being self taught I'm impressed.
great start on Mother’s Day
Interesting intro on the CNC lathe, you can see how programming is so important in order to prevent damage to the part or lathe. Great job.
Congrats on your new shop lathe. I’ve never used conversational to program , looks like you got making parts fast.
I’d personally leave all the M1’s in after ops. When proving out a new program , leave optional stop on, then turn off on proved program . Helps prevent tool change crashes with long bars or drills.
Cheers
Setting up the lathe is indeed interesting to me. Back in the day all that we had were manual lathes and that is what I learned on.
Always a great pleasure watching the both of you working 👍🏻👍🏻
32:52 "Grind that, black flat, it doesn't need to be that far back". Sounds like the title for some song.
Look at him, sooo chuffed with his new tool. Love it!
Consider a shorter spring so it doesn't launch your plugs, and a recessed o-ring in the plug shaft to provide a little resistance to the spring.
Or, just make enough plugs that there's always a few around your feet, ready to be grabbed and used 😆
Chuffed. Definitely a friend from across the pond
I programmed Okuma lathes for a few years, loved those things. The controller built into it is able to program any toolpath and even had the ability to run live tooling.
Loved the video! Totally new to CNC process. Appreciate the start to finish on a new part. Thanks! Keep it up!
Neat, I have a little manual lathe at home, I've always been cnc curious. At first I was kind of critical, thinking about how I could have manual turned the plastic bit in less time than it took to program, but the real magic comes when making more than one part, and knowing that they will all be exactly the same, and the machine can just hammer them out.
Nothing cooler than CNC, you guys know what you're doing cheers for showing and explaining everything.
i am always amazed at dads knowledge !
Just being willing to try new things puts you ahead of most! Congratulations on the little one.
The TL is a great little lathe. Just finished a semester on hand coding and used a similar TL1 with the same 4 tool setup. One suggestion because the TL2 does not have a Tool Presetter. If you are setting up multiple tools, use the Tool Offset measurements. Leave the Work Offset numbers at 0. Once you touch off all the tools, you can then fine tune with G54, such as moving your Z closer or further from the spindle. Maybe leave the M01 and you can just turn off the Option Stop. Also, Leave a .002 on the diameter. After the last plunge of the groove tool behind the knob, do a G01 X to final diameter, then a G01 Z- move to part off length at slower feed rate. This will give you a nice finish. It's ok to do a side move with the part-off tool with such a light cut, especially on acetal.
This kid must be on cloud nine, he just welcomed a healthy baby girl to this world and he's learning how to use the new toy in the shop! It'll be fun to see what new machines RUclips ads pays for in the future lol
Love this idea. I do a lot of stroker small engines for mini bikes and stuff and I could definitely use something like this for checking block clearance. I don’t have a CNC lathe in my garage but I’ll have to try to make something similar.
I remember having a CNC class in high school. It was a technology class where we learned about how to use a CNC mill where we programmed in how to just make words or letters in a piece of plexiglass. There was also something with robotics. But I don't remember much about that. I just remember more about the CNC stuff. But at this point isn't really much
Sweet trick with rod and substitute piston to check clearances
Great video. Really enjoying this series. Thanks for sharing.
Amazing bit of kit .
You should consider putting a clear view screen into your lathe. It is a round window that spins extremely fast and stays clean no matter how much coolant or chips hits it.
Interesting tool to solve a problem ! Thanks for sharing !
What a beautiful machine.
I loved the detail and explanation through the whole video. Great job
Congrats on the new Machine. Always improving 👍👍👌👌
Nice work Nick.
Certainly damage free testing.
The CNC will sure be another nice asset for your guys shop.👍👍
Thanks for sharing.
pretty cool working on the new lathe, love videos like this
I really enjoy your videos.
congratulations on the brand new baby!
now i gotta be waiting here for 7 hours … ☕️
Those ultra low mass pistons look GREAT! I think compression might be down but otherwise 👍! 😂 Babys fuzzy little head was super cute; enjoy her!
First real job I had after high school was running an old hardinge cnc lathe made in the 70s....everything was g code programing....You are doing a fine job.
If you end up using those wrist pin buttons a lot, you can add a through hole somewhere close to the ends of the pin and a slightly oversized through slot on the shank of the delrin button. Chamfer the through hole in the wrist pin and drive in a roll pin that’s slightly shorter than the OD of the wrist pin so it’s below flush on both sides.
The slot in the button will allow it to move in and out while being captured by the roll pin so they don’t keep popping out 🫡
Ok there is clearance between block and rotating mass but is there clearance between the cam and rotating mass
That is some machine! I personally like manual. I have a really nice 80’s style 13X40 Clausing like bran new. I scored when I found it!
I never heard of that chuck. I have Pratt Bernard
Now you have a new tool to sell on the website.
Thanks for sharing... Keep up your awesomeness...
Nice work
Great job!
thanks for video
I cut strips of cardboard from a box that has corrugated cardboard. It's plenty thick and you can hold it down in areas you can't get to such as where the rod passes the cam tunnel area. The cardboard clears without getting pinched and that tells me I have plenty of clearance.
Very nice video.
God bless y'all
GREAT tool!
Great show. I love how you take time to explain and show the detail execution of your work. I am under the impression that risers in casting is a source of weakness. Would it make sense to remove the casting marks inside the block (like above the main journal)? Would it be helpful but is not worth the effort in this particular case?
Love the new machine, and love that you’re brave enough to show your lack of knowledge on CNC. As a CNC machinist/ programmer, I’d highly suggest looking into inserts that are specifically made for plastic or whatever material you’re planning on running. Make sure to document the speed/feed combo and you’ll be cranking out amazing parts in no time.
you could put a thread in the shank of one button, and then drill a deep counterbored hole in the top of the other one, such that a correct length socket head cap screw would fit in and slide, but also hold the buttons in the sleeve. That would stop it from popping apart every time.
Nice job!
You guys are and great Info
Nice job and good content and thanks 🔧👍
30 year toolmaker CNC and manual here, these are easily knocked out on a manual lathe. But... if you got a Haas deal due to your content, good on you! Also there are cutoff cycles that plunge a little then back up and chamfer the part before final cutoff.
Definitely not a Haas sponsor deal for our content, we paid full price. I'm just excited to learn something new & show the process with our following. The rest of the equipment in our shop is manual and specialized to engine machining, so this is exciting for us lol.
I'll see what I can learn about the cutoff cycle that plunges then chamfers... Thanks for the tip!
Congratulations on your new CNC lathe. Hope it helps in the future.
Great idea men.. Why didn't we think of this
I think that I saw these made with flat ends, which may actually help to center it in the bore.
People should use the counter weights on damper n clutches so the oil don't slow process
You could write that as a parametric program, where you set a variable for the diameter of the pin, and all the code for the shaft of the pin uses that instead of a fixed value .... change the value and you can make a new pin for a different ID gudgeon pin.
That was my thought, just don’t know how to do that yet! 😂
So much to learn.
Nice machine
They would be much better if they were made from a colorful material. Red, blue, green, yellow, for different sized wrist pins.
Suggestion for tool version 2.0 …. Turn the outer diameter of the spring end of the button to fit inside the first coil of the spring with a little retention nub or rib so your buttons don’t spring out every time you pull them out of the cylinder. Just enough so they don’t pop apart, but not so much you can’t pull them apart.
Put threads on the plastic nubs and screw the spring from both sides on the nubs so they don’t fly away, just compress and decompress.
That’s a lot of machine for a 2 man shop! Where CNC excels is repetition. It will pump out a thousand pieces exactly the same and never get bored . You need a project piece to sell and knock out as many as you can sell to make your money back.
CNC does awesome with repetition, but IMO it does awesome for prototype/ one off parts too. I always heard CNC was no good for one-offs… now I totally disagree. I don’t have a lot of experience running a manual lathe (literally one semester in college) but I would argue the CNC is more efficient and more capable any day
You are exactly right I hope he has other plans for the Machine Tool to justify that project
The software packages you can get today make CNC machines almost turn-key, don’t they? So one off parts are (relatively) quick & easy.
I was a young engineer at Ford Engine Engineering when we got our first CNC mill. This was around 1968. Our drafting room was coming up to speed on the CAD side of the design work but the CAM side was at ground zero. The machines, tooling and some of the CAD software came from the aerospace industry like Boeing and Lockheed.
The department manager had spent a ton of money on that CNC mill and wanted to see production ASAP - sooner than that actually. He tasked the lead tooling engineer to write the machine instructions for the tryout project - an inline 6 cylinder head. That was a big hunk of cast iron and Dennis really struggled to learn the programming as he worked out the tool paths. There were a lot of crashes. Broken tools, broken head castings, broken spindles. Dennis got more nervous by the week. Pete, the manager, gained a nickname for his pet project. Pete’s Folly. I was standing with Dennis near the mill one morning when Pete walked up with a cup of coffee, and we watched another crash. Just a tool this time. Pete looked at his styrofoam coffee cup and said. “Hey Dennis, can we get some big chunks of this coffee cup stuff, cut out cylinder head-size pieces and machine those? Then a crash won’t break stuff while you & your guys figure out how to program this mill.
They did. The machine didn’t get broken, and within a couple of weeks Dennis got the hang of programming tool paths. He said that one day it was as if the ol’ Ford light bulb turned on and he was a CAM programmer!
The technology has come a long way in (gasp) 55 years.
I’ll be 82 in a few months, been retired for years, but still love this stuff. Love your channel because you do a great job explaining and executing top-notch quality work.
Let's be honest here, men that enjoy and do this kind of work also just love cool stuff/toys. Let them do what they want, it's there money, stop nagging like a jealous woman
My suggestion, take a pin, thread the inside and make a couple of threaded delrin so you could center up the pin and they won't launch out like rockets
Also on the end of the connecting rod bolt i Tig welded a point to help my guys hit center of the bolt, I can mark around the bolt but one of my guys really needs to know center to help clearance
Groove the stem of the tool for an o-ring. Use a spring long enough to expand them as needed but short enough so the o-rings stay inside the wrist pin. The friction will keep them from leaving the building when pulling the rods out.
Nice. Much easier to store than a clean pristine Styrofoam cup insert.
Had my question all typed out about half way through the video. You answered it 3/4 of the way through. It had to do with piston skirts and counter weights.
So the thing about G-code is it's describing machine moves and behaviors directly. It's used on almost all CNC, whether a lathe like yours or a little hobbyist 3D printer.
The conversational programming is cool as hell, and is in the same toolchain position as a 3D printing Slicer, which takes a model, slices it into layers, and then figures out the perimeters and infill, and plans out all the moves. This is then turned into Gcode to send to the printer. The printer's task is then to plan out the acceleration, and Act on the gcode
One very visible advantage of the cnc lathe over a manual is the progressive RPM based on the cutpoint radius, making the facing cut finish homogeneous across the entire cut rather than outside being perfect and inside being under speed
Good job Nick! You did well on your new cnc machine considering you reckon you know little about it!
Dropsy with the new tool as you undo the big end caps must be agrannoying! Maybe you could install a coupla shear pins to retain the delrin bits & stop them flinging round the shop? Only practice might stop you dropping them though!
To fix the the new tools cap going every where, make a slots in the plastic cylinder that slide inside the metal shaft drill a small hole in the shaft on both side close to the ends and dive a pin thought the shaft and the plastic cylinder. that way when the pins will hit the end of the slots in the cylinder it will not pop out and the whole tools will stay in one piece. If you think the cylinder wont allow the plastic half to go out enough, just make the plastic cylinder part longueur, this will also minimize the need for a larger spring while the pressure of the wall from the plastic half sphere to be not so hard .
Francophone? Longueur in the middle of sentence. Anyway I agree.
When I was teaching Advanced Programming I always said an expert was a person who knows as little as 10% more than you do. You’re already orders of magnitude more expert than me 😎
Quick question? When checking the clearance do you use the actual bearings that are going in the building? Or a second sacrificial set? Just wondering about potential damage to the actual bearings?
Brilliant work! I was really in when you used a file, real tradesmanship. This looks to be coming together really well, cannot wait for the next instalment. Oh yes, CNC, what? Sorry, I am older than the cleaning guy and I have never seen nor used anything CNC in real life, manual turning only for me. I do like the new visual programming software though, looks pretty intuitive.
re the lathe, and a project . something a guy we knew did was took a wood shovel etc handle as its hardwood and turned a taper onto it after a few inches, so when your towing / lifting something with ropes. you can tie a knot with the piece in its middle, then when your done the lift/tow, You pull the stick out as the taper will allow it to slide out and the knot wont as a result be so tight you wont get it apart. Handy for those that cant tie knots well.. and have a knot you'll never get apart .. Handy with old hands.
Just make skim cuts to set the work offset. Moving the tool up against the material can chip inserts. Especially inserts with a small tool nose radius.
On a side note cutting delrin can be hazardous to your health. If you can smell it being cut that's a bad thing. It releases formaldehyde when it gets hot.
I have no clue abut CNC machining, it's interesting. I noticed you're doing your clearance checks with dry bearings, are you taking in consideration of what oil in those journals will do to your clearances? Just curious or does it not matter?
Make a holder for those "tips" you made, mark them as to what manufacturer they're for, will make things a whole lot easier for you as you progress with all your builds. Great video as always, cheers :)
It wouldn’t make a difference, but there is actually a small film of oil on the bearings/crank journals.
@@JAMSIONLINE Ok, as I said, was just curious about that. Thanks :)
Cool tool works good maybe you can course thread the end of both buttons so you can actually thread it into the spring on both inside the pin so the spring tension is lessened as well you don't have the buttons flinging or coming out everytime you remove it from the cylinder bore.
This is the OF of engine building!
If you noticed that spindle speed ramping up during X- movement, that's due top a G96 which is constant surface speed, very handy and good practice. The little things I could mention are not going to help you but you will figure them out in due time. Good thought process on your part.
Re-machine them with a slight raised rib on the stem, that way the compression spring will grip them...
maybe mill a groove in the delrin plug shaft and add a set screw to the housing to avoid the "every time!" situation?
I'm working on a Toyota Dyna 14BT engine at the moment. Blowby issues have become untenable. I have to measure it up, and if it's too worn, I will have to remove it from the chassis and have someone bore it. Keep up the good work, guys.
Aren't piston pins offset in the piston to better attenuate piston side load during the power stroke? IOW: The pin wouldn't be straight in the bore. I realize it isn't too much difference to to position of the big end of the connecting rod, but still, there is a difference.
Some pistons have offset pins, but it is by a small amount, and the difference it makes in the big end is, as you suspected, very very small.
Love the CNC lathe. Of course in case of snafu you can blame the young punk, not the cleaning guy .. 🙂
My I suggest getting orange stock to make the tools from so you can find them faster 😂
Really like your channel!
My two cents for the issue of the buttons popping out and away.... If they were made without the enlarged end, so the whole thing would slip in the pin. After all, the only part that touches the bore is the center.. the radius could stay the same . then they could be attatched together with a tether ( a wire or thin cable) inside the spring. possibly attatched with a small eye screw in the end of each piece.
