Remember that if you use heat and cold to install, the cylinder will shrink while the sleeve will grow. That makes it shift slightly from the center to both ends. So you have to use the press during cooling to keep the locating flange in contact with the barrel recess.
i think the problem is sourcing liquid nitrogen in norway its the same problem in sweden for private persons and its not the first time he will use the press so we shouldnt jinx him now
The barrel should be thougherly heat soaked before trying to fit the sleeve. Remember what happened to the Brute Force liner when that was pressed in cold. It buckled!
@@Alexxx95_H But the engine heats and aluminum expands at a greater rate than the ferrous sleeve. One would have to figure press for hot size of the bore to hot size of the sleeve.
Great to see that your thought processes and investigations were able, along with your ingenuity were able to overcome the angular port issues. Waiting patiently for the next video.
I love the creative fixturing but I think a sine plate to mount the vise to would make this job lot easier if you have to machine angled ports like that again ;-). They're not too expensive used and if you're not trying to get within fractions of a degree they can be made in the shop. Can't wait to see all the hard work pay off on the dyno, keep up the good work!
Absolutely love the way you manage to overcome obstacles in front of you and your ability to persevere to the end product even if the way there is tough, great inspiration :D
I was worried for a while because there was no activity. 😢 This video shows that you're at it again with a lot of energy. 🎉😊 Great, keep going, we're rooting for you!
Making something from nothing is far more difficult than most people can understand. I feel your struggle my friend.. trying to make the things you can't afford is a tough battle. But boy is it satisfying when you succeed! Keep it up my friend, persistence will prevail
"chatter" pronounced (Chat-ter) machining, vibrations, also called chatter, are the relative movements between the workpiece and the cutting tool. The vibrations result in waves on the machined surface
You really are a wizard! Love the content and your willingness to improvise new solutions. Can’t imagine what you could do with some real factory equipment and backing!
The best channel on YT! I check for these videos everyday after work like a drug addict who hasnt had a fix in a while. Only channel that i dont get burnt out on!
It’s pretty amazing how far you’ve come with the capabilities in your shop, when I first started watching you you would have done that with a drill press and a rat tail file. Crazy thing is you’d have made it work either way, maybe that’s why Henry Ford got his start ❤🙏🇺🇸
A small rotary table on its side works well to give you the correct radial (directional) angles,i used tbis before cnc porting obviously the axial (roof) angles have to be done either with a tilting head or rotary table, unfortunately i cannot post pictures of my setup pre simultaneous 4 and 5 axis cnc
I’m not sure if this would work but you might be able to use a tapered end mill. Love the videos, I’ve learned so much from them and it’s cool to see how much you can do by yourself in your garage
You are honestly awesome you are doing my dream of just building amazing things would kill to have the equipment to build my own engine keep being awesome man!!
I have an older 4th&5th axis addon. It has its own cnc controller. You will have some issues to fix with your z-height. You can have it for free, if you pay for the shipping from Denmark. I can send you some photos of you are interested. I think it is a bit too big for your cnc, but i bet you can figure out something. Write me if you are interested. Keep up creating great content!
Alex...as usual, great improvisation! If you have a few minutes, why don't you share some of the details about your forthcoming water brake dynamometer? The water brake could be the turning point in your quest to obtain accurate, reliable, and repeatable data for your program. Slow-and-steady my man, and try to tune-out the haters.
Make a 20-30mm aluminium fixture plate for your table with two threaded holes and two holes to mount the plate, make the octagonals have holes on each face, screw cylinder with octagonals onto fixrure plate. For posistioning you could add “styre hylse” permanantly to the table fixture, and make h7 tolerances holes in the octagonals. And if you need to tilt the part you can use a sine bar/ paralells / angle blocks under the fixture plate 😀. And make some inserts for the table mounting so you can easily tilt the plate.
You should contact inheritance machining! He designs and builds lots of custom tools and im sure he would be able to help with the clamp setup for the milling machine that would work for you.
"Shaa-turr" is how we pronounce "shatter" over here in the USA. It's a "T" sound more than a "D" sound, like "flatter" instead of "ladder". Shatter rhymes with matter, spatter, clatter, batter, patter, fatter, scatter, etc...
you need a low profile collet holder or something similar. you are unnecessarily losing a lot of z height because of current holder,. This would also give you more rigidity. You could also make your own . it is about a 4 day project.
I think i have a solution for your 100% eliptical exhaust port/piston ring issue.. Make it more 'trapezoid' on one side of the port. You can still maintain the same surface area without the ring popping out.... Maybe 😊
On your z axis, could you raise the entire head up with a 100mm spacer block, know they make a "riser" block for bridge port mills, same basic idea, build a box, 100mm tall or how much mre height you need, raiser goes between the z axis column and mounting base of your mill, that way you can buy that indexer and be able to use it, just a thought, hope helps!
Have you thought about your existing mill and ballhead carbide file. From geometry point of view, it shoud be capable of making shapes you need. You'd need a software, capable of making right tool paths. I'm not sure how geometrically accurate those are, but I think good ones can be quite accurate. They are not fasters way to machine metal, but in your use-case, it don't matter much.
Spörsmål Alex: is the pillar on the mill screwed to the bottom of the machine? i am thinking about a spacerblock for the pillar itseld to get it higher from the table - CEE Australia did a similar thing to a K&W facing borer th-cam.com/video/yWYPCaVubi0/w-d-xo.html Edit - yes it seems to be..i can se the bolts holding the pillar at 9:30 , so a rizerblock for the pillar shoud be possible to fit- and sinse you dont even can run the quill all the way down a 100mm block woud help a lot in that machine
One answer to your Z-height problem would be to use shorter toolholders. An extreme example is the zero-length one I made here: th-cam.com/video/fym44wESy8U/w-d-xo.html I mainly made my own because I couldn't find BT30, bit you seem to have a 40 taper machine, so they are available.
DROP EVERYTHING THE 2 STROKE WIZARD IS BACK
I know right!! xD I was fired up when I got the notice on the phone! =D
Was just putting dinner on, was perfect for watching whilst cooking. 👌
Literally
What just dinner, I took a week of work to watch it on loop 😂😂😂………..
Hell yeah
Please never stop doing this.
Lol you know he wont.... Depressing.
best and realest guy ive seen so far

Great to have you back on screen and sounding so positive
This is why I come here and it's to watch you Alex overcome obstacles and use the tools you have to make stuff work,
Hi My advice is do not press the cylinder use nitrogen - 180 c and warm the barrel to 100c or you may have a disaster buddy
I second that motion.
i think the problem is sourcing liquid nitrogen in norway its the same problem in sweden for private persons and its not the first time he will use the press so we shouldnt jinx him now
The barrel should be thougherly heat soaked before trying to fit the sleeve. Remember what happened to the Brute Force liner when that was pressed in cold. It buckled!
It is not necessary to use such a big contrast temperature. If you calculate the press fit right, it is ok if you just cool it in the fridge to -20C.
@@Alexxx95_H But the engine heats and aluminum expands at a greater rate than the ferrous sleeve. One would have to figure press for hot size of the bore to hot size of the sleeve.
You look a lot happier I hope you are feeling a whole lot better. Love the content.
What an awesome mind you have my friend. The ‘ch’ in chatter is said like it is in cheese. ‘atter’ is the same as in mad hatter!
You should be well pleased with that sleeve imo. Nice work. Super cool to see it being made from scratch!
Wow! I can already feel the power from this thing! 20k rpm screamer!
I follow you from aroud four years now, and it is always facinating . All the mix , the creativity, the knowledge, and the weird ideas. really cool.
Great to see that your thought processes and investigations were able, along with your ingenuity were able to overcome the angular port issues. Waiting patiently for the next video.
If only my super power was to make a sine bar plate appear anywhere on the Earth.....i guess in the past too. Glad to see you getting traction again.
I love the creative fixturing but I think a sine plate to mount the vise to would make this job lot easier if you have to machine angled ports like that again ;-). They're not too expensive used and if you're not trying to get within fractions of a degree they can be made in the shop.

The best channel on YT! I check for these videos everyday after work like a drug addict who hasnt had a fix in a while. Only channel that i dont get burnt out on!
By the way... I had a tilting drill vice! That would give you an extra axis.
The knowledge you've taught me is very appreciated. So if it means anything from a small person in the world thank you
It’s pretty amazing how far you’ve come with the capabilities in your shop, when I first started watching you you would have done that with a drill press and a rat tail file. Crazy thing is you’d have made it work either way, maybe that’s why Henry Ford got his start ❤🙏🇺🇸
For milling in n angle you could use a sine bar
Not that I know anything, but I am happy to see the new dyno with small pitch chain.
Really like this project.
A small rotary table on its side works well to give you the correct radial (directional) angles,i used tbis before cnc porting obviously the axial (roof) angles have to be done either with a tilting head or rotary table, unfortunately i cannot post pictures of my setup pre simultaneous 4 and 5 axis cnc
Best 23 minutes of the week :)
That jig is BRILLIANT. Insane that the 25 is so repeatable
Really liked your fixture for holding that liner in mill, good work mate
Great to see you back Alex….was starting to worry!
For those undercuts, it might be worth looking into using a tool capable of reaching around the corner so to speak. Like a t slot or dovetail cutter.
Plumbers freeze spray, it's readily available, cheap and get a couple of cans. Being freon gas it's not restricted and if soaked good for around -40c.
I love your enthusiasm you keep pushing your craft it makes me want to work on my stuff more! Keep it up buddy!
I’m not sure if this would work but you might be able to use a tapered end mill. Love the videos, I’ve learned so much from them and it’s cool to see how much you can do by yourself in your garage
You could use an octagonal collet block to hold the sleeve
He kinda did right?
I was thinking the same thing
We miss you Alex! As always, great work! I admire you!
Well done, very impressive work on such limited machine tools
BRAVO ! just simply ! most innovative machining 👍
You could 3D print a series of fixtures that would reference features in the part to create a multiple orientation system.
a temporary keyway for a mandrel wouldn't be a bad idea if you can and you could get the port angle by making mandrels with offsets
YES YOU ARE BACK AGAIN
Was just wondering when the next video was going to drop. And here it is!
The piece looks really good! Great work 😊👍
It great how you do what you do with the tools you have.
Awesome work and great video as always thanks for sharing it bro
i think a much brighter light around your milling machine would show you more. good to see your at it again.
Was about to sleep, but i guess 4 hours of sleep is good for work. Blessed by the king of 2strokes
The man, the myth, the legend himself has posted again people!
Like that video!
You are honestly awesome you are doing my dream of just building amazing things would kill to have the equipment to build my own engine keep being awesome man!!
Hi I would consider buying direct colletts. A few common sizes at least. You could eliminate the tool holder Z height. I guess over 50mm
I have an older 4th&5th axis addon. It has its own cnc controller. You will have some issues to fix with your z-height. You can have it for free, if you pay for the shipping from Denmark. I can send you some photos of you are interested. I think it is a bit too big for your cnc, but i bet you can figure out something. Write me if you are interested. Keep up creating great content!
That's a big achievement and good problem solving.
Cylinder looks awesome IMO. Can't wait to see it running though. 👍
Brooooooooo that sleeve looks sick! Nice job!

I feel like this is the only channel on youtube without haters :D
What's there to hate? I love watching this, the drama, the struggle, the disasters, it's all happening. Yay!
3d print custom fixtures for each job, cheap flexible and low profile
You could also get some shorter tool holders to give more z axis capacity
I started to worry you weren't coming back 😂.
You got this!!
Fantastic work Sir.
You've been busy Alex I see, great editing, the sleeve is looking good 👍❤️😁
Nice job man! Great ingenuity!
One of your best videos. I think you can expect to get toolmaker certification in the mail soon haha awsome
If you fabricate a solid riser block for your z axis on the cnc mill, you will have head room for the tilt device. Love your videos👍
Make a 20-30mm aluminium fixture plate for your table with two threaded holes and two holes to mount the plate, make the octagonals have holes on each face, screw cylinder with octagonals onto fixrure plate.

Looks beautiful!!
A work of art!!

Alex what about a sine plate as a mounting base and the make an adapter with the degrees marked on it to get the ports at their right angle
YES the 2 stroke god is back!!
Well done on a 3-axis machine, time consuming but doable! :)
Can't wait for the next video 🔥🔥🔥🔥
I think i have a solution for your 100% eliptical exhaust port/piston ring issue.. Make it more 'trapezoid' on one side of the port.
You can still maintain the same surface area without the ring popping out.... Maybe 😊
4:42 mount the diving head higher an on a 90 degree angle plate so you can tilt the head down instead of up?
Necessity is the mother of all inventions
The norwegain in the beginning caught me of guard. thougt it was swedish at first :D
förvirrande! var tvungen att spola tillbaka 😆

smart solutions as always! 🙂
Use your CNC to make steel sand core boxes, cast cylinders again
Great job Alex.
yo i think it's insane youre making rotax race kart engine power with half the displacement
i hope all the best for you my man
Looks very good.

I think it should be "Perpendicular" to the arm pivot piont that is acting upon it not the disc centre
