I bought my first shell mill recently which is great for material removal, but nothing beats a single-point tool for surface finish, as your video demonstrates. I might have to make myself a big fly cutter too!
Abom and his collection of tools to do every last potential job in the shop has its place, but videos like this where just basic machine shop tools are used are fantastic as well.
Whilst you were making the wheel at the beginning of the video I was already thinking to myself: 'oh man, with that much mass in a single point cutter, the surface finish will be outstanding'. A near mirror finish! Beautiful work!
Robiłem taką głowicę do planowania (fi440) 5 lat temu dla zakladu który osiuje bloki od 5 lat także planują i wychodzi im to naprawdę dobrze tylko trzeba odpowiednią płytkę skrawającą. Za głowicę wziąłem 1500 a typowy fly cutter wloski okolo 100k, oszczędność niesamowita.
@9:02 "ok, this works. Now to find something I actually need to fly cut.." Great project. I just found a use for those old brake rotors sitting outside. @5:06: I had the same feeling watching that as when it happens to me. Kudos to you for including the bad with the good.
I´ve been thinking all the time, "this would be perfect for a cylinder head" :). Then you got one. And threw it back on the pile afterwards.. Nicely done! Nice tool!
Osobiście zrobiłbym pierścień inaczej nieco; Obecnie na śruby trzymajace trzonek noża działają spore siły ścinające, zrobiłbym kanałek frezem w pierścieniu, żeby utrzymywac też nóż na ścianie bocznej(przeniesienie sił na ścianę boczną trzonka) Ogólnie fajnie!
To jedna sprawa. Druga to ustawienie wysokości ostrza. Na śrunach będzie się przesuwać-pracować i może skrawać tylko jeden nóż. Z resztą flycutter'y mają jedno ostrze.
Нужно ставить 4-6 резцов Вырезать под них углубления Чистота будет лучше, точность выше Нагрузка на станок меньше Мы такие фрезы в путяге делали диаметром 400мм 16 резцов.
I like the use of the cutter to allow easy use of replaceable inserts. I have 1 minor worry/ suggestion. The way that it is mounted at the moment all load is transferred into those cap screws holding the cutter on - this risks both thread damage and tip wander under load If you where to measure the cutter size and recess it by 1/4 the cutter width into the main flying plate you would remove both of those issues resulting in a more consistent and longer lasting tool
Yes recessing would be a very good idea and while you at it counterbore the holes for the cap screws so they sit closer to the bottom. You could also use 3 cutters instead of 2 as an uneven number will run better.
@@yaykruser he didnt, if you look at the next scene he is using a larger tap. He probably drilled it out or shattered the smaller tap then drilled the hole larger.
I don't think I would want to be around that thing when those two 6mm bolts finally have enough and shear leaving that cutter to go flying at 100 miles per hour. He should have machined slots in the body that would fit the cutter snug and then bolted them on. That way the body of the cutter would support the cutter and guide it leaving the bolts to do what they are meant for which is to secure it. It's a nice idea but it's not finished and as a result it's damn dangerous.
I had the very same thought. Mill slots the precise width off the cutter bars so that all the lateral shear load is carried by the circular base and the bolts are appropriately used to secure the bar down into the milled slots. As it is now it WILL fail when eventually the bolts shear off, which by its self is bad enough, but then the cutter bar is going to become a projectile flying off hopefully not towards someone, but what's more the cutter is instantly going to be out of balance, the severity of which will be determined by the RPM of the cutter. To give an idea of how violent this can be I had a close friend who was flying a Mooney personal aircraft, engine RPM was 2400, when suddenly 4 inches of a 60 inch propeller blade broke off. It was so violent that loosing just 4 inches of the tip was so instantly violent that before he could kill the power it had broken three of the four engine mounts, almost tearing the engine off the front of the plane.
By far, one of the better fly cutters made on this app. At least it has two cutters. The surfacer I used for blocks and heads had 8 and the finish probably wasn't any better
Very nice! I would like to suggest to mill two slots in the circumference of the disc in which the tool has a tight fit for improved rigidity. Just an idea.
@@fransmartono8394 And why does the tool need to be adjustable when you can just move the quill !! The tool being adjustable is just another area where you have to be concerned about rigidity and alignment . You don't work in the shop do you... People walk into my shop all the time and tell me what I should do , And if I took their advice , I'd be out of a job !
That was my thinking too. Cutting a triangle would work as well. More easy to perform with the opportunity to fix the bolts 90 degrees around to have them in turning direction, gives the tool more stability.
I was just thinking "nice long handles on that tap wrench... " when it broke. Been there mate! Sometimes you can get it out, but it hurts every time. Lovely smooth surface BTW.
I felt bad for the guy when the tap broke / especially after the threads were cut - been there / nice work my man - you inspired me to do something similar!
Nice job! Just a thought: How about machining close-fitting slots to locate the tool holders? This will transfer the shear load from the retaining bolts to the mass of the big plate.
I'm guessing that the mounting bolts are the designed point of failure when something goes horribly wrong. If the shanks are seated in the disk, something more expensive is going to be the failure point.
You can use a hole saw and cut around it, then press a bushing in there, for example. Or just weld the whole thing, turn it and start over on a new spot... Pretty simple as it's a round part.
2:35 leaving that chuck key there isn’t very good. 6:00 that isn’t much support for the cutter, why not imbed it most of the way? 6:34 the Allen bolts are in only a couple of turns. WTF? Scary!
@@99owL yes. His passes are too deep. Doing that will significantly reduce the cutter's life. And if precision is in the picture and you start turning sparks, you'll end up with less than optimal results.
I have no idea what you are saying, but I'm sure its something along the lines of, 'that tool is strong like bull or bear.' So I'm giving you a thumbs up!

@Chris the disk is well mounted to the spidle. The two bolts are simply a safty design i guess. It doesn't spin on high rev, so if it breaks down no one gonna get any damage. But if you mill a channen into the disk, the whole spindle and disk going to get serious damage. I realy disagree with you.
@Chris i like when people come with their experience. No offense by the way. I have also experience in making my own custom tools for a specific job. But also I have less experience in years compered to you (if true). But it doesn't mean anything. My opinion is, this is a well made flying cutter. It doesn't need high RPM to operate at optimal. So the chance it makes serious accidents is very low. I agree with you about the bolts, but it doesn't need any channel or clamping mechanism to tighten it. Just think about the weight of the disk. With a channel and clamping it would make worse damage in both the operator and the machine. As I said, with higher diameter you earn the same surface cutting speed with less rpm. It just need proper balancing.
Good job looks solid, I wondered if the three indexing tips had to be checked for height then tightened. Would be good to see a DTI run along the profile after the cut.

Beautiful job on the cylinder head! I only wish my milling machine had enough travel on the axes to fly cut a head. Nice tool.
I don't think I would want to be around that thing when those two 6mm bolts finally have enough and shear leaving that cutter to go flying at 100 miles per hour. He should have machined slots in the body that would fit the cutter snug and then bolted them on. That way the body of the cutter would support the cutter and guide it leaving the bolts to do what they are meant for which is to secure it. It's a nice idea but it's not finished and as a result it's damn dangerous.
Under the loads he's using here shear is less likely - The more major issue is that there is nothing but thread torque to ensure it never wanders
I had the very same thought. Mill slots the precise width off the cutter bars so that all the lateral shear load is carried by the circular base and the bolts are appropriately used to secure the bar down into the milled slots. As it is now it WILL fail when eventually the bolts shear off, which by its self is bad enough, but then the cutter bar is going to become a projectile flying off hopefully not towards someone, but what's more the cutter is instantly going to be out of balance, the severity of which will be determined by the RPM of the cutter.
To give an idea of how violent this can be I had a close friend who was flying a Mooney personal aircraft, engine RPM was 2400, when suddenly 4 inches of a 60 inch propeller blade broke off.
It was so violent that loosing just 4 inches of the tip was so instantly violent that before he could kill the power it had broken three of the four engine mounts, almost tearing the engine off the front of the plane.
It is interesting that he thought to attempt to balance the load but did not take the time to cut slots for the cutter or the balance.
By far, one of the better fly cutters made on this app. At least it has two cutters. The surfacer I used for blocks and heads had 8 and the finish probably wasn't any better

Great job,
But how did you took out the broken piece of the tapping bit from the fly cutter @ 5:08 ??
I think he extracted it by cutting the piece out with the broken tap in it with an angle grinder,and welded it up.
Norbert Hajzer
But the bit has broken at the edge of the fly cutter surface , there is no extension part above the fly surface for welding !!
@@مواطنحر-ف1غ Yeah but he could true it up on the lathe after the welding.
I did this a couple of times, just cut a"v"out of the material,and weld it back up,but only if it's mild steel, otherwise it will harden.
I would've cut grooves for the indexable cutters to nest in, instead of just having two screws holding each cutter.
Отличная "балеринка"!
Greetings from the Great State of Arizona! 1st class work !

nice work, only thing i would have done is slotted where the tool holder bolts up.
That was my thinking too. Cutting a triangle would work as well. More easy to perform with the opportunity to fix the bolts 90 degrees around to have them in turning direction, gives the tool more stability.
Just curious , But why didn't you cut slots for the cutting tool to sit down into so it would be more ridged ?
