[@MateuszDoniec]

Thank You Bro

[@bengrogan9710]

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

[@blacksheep9734]

Ben Grogan my exact thoughts

[@skostasx]

I definitely think like you

[@vankuipland]

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.

[@bengrogan9710]

@@vankuipland this is a single point fly cutter - the 2nd side is a balancing counterweight not a cutting tip

[@uhmgawa6533]

@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.

[@janvisser2223]

[@bauerleinjohn]

Did you make it a double tipped flycutter to balance it out? Just trying to figure out benefit of double over single point, maybe you can feed faster with similar finish to a single point at slower speed, but I imagine the balance is the reason

[@MateuszDoniec]

[@СергейВасилич-х6ы]

Фреза рабочая.Только нужно было бы под резцы пазы фрезернуть.

[@bruceinoz8002]

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.

[@somebodyelse6673]

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.

[@resort4994]

Ну, что ж, давайте заставим Матвеева повторить!) Вы знаете, что нужно делать)

[@DPWPERFORMANCE]

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

[@oh8wingman]

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.

[@bengrogan9710]

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

[@scottpecora371]

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.

[@thinkfirst6431]

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.

[@balthazarnaylor5874]

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.
