Making a MASSIVE Fly Cutter || INHERITANCE MACHINING

Welcome back to the manual machine shop! In this video I’ll be taking on everybody’s favorite cutting tool. The fly cutter But of course I will be putting my own flare on it, by making it MASSIVE. And not only that, it will also be adjustable in diameter and will accept tungsten carbide inserts. The motivation for the project comes from yet another project where I will need to be able to fly cut a plate 9 inches wide. As normal for my projects, the engineering behind all this is done on a good old fashioned drafting board. The build will be made up of several components, made from different materials I already had laying around the shop. An R8 arbor to match my vertical milling machine will be press fit into a large aluminum wheel that makes up the bulk of the cutter. But to make the cutter adjustable, a separate insert holder will mount on the wheel via slots. Some other miscellaneous hardware round at this build. And as many will be pleased to see, I’m actually black oxiding the parts this time! But mostly for looks ;)

Thanks for watching, folks! Tune back in Friday, December 9th for the real motivation behind this project, another project!

[jrk]

making tools to make tools to make tools... the never ending shop dilema

[dgphoenix]

I didn't see any flies get cut. I am disappointed

[thehunters]

The number of times your ‘gut feeling’ or ‘instinct’ to ensure your machines are true and properly set up have saved so many of your projects is unreal. You’re awesome Brandon!

[mastershake]

If the earth was flat this man would find the edge and put a chamfer on it!

[NeMoC]

The laugh at the culmination of all your efforts! 🤣 you sir, are a champ! Thanks for all your content. It’s aces in my book! Looking forward to December 9th! (P.s. I’m asking for an IM hoodie for Christmas from the wife and kids. 😎)

[kimtae]

I love the difference between calm, enunciating narrator-Brandon versus the chain-cursing, hippy sounding shop-Brandon

[jonathanrudy]

I absolutely love that the box of shame is a thing, and even as short as this channel has been around, I immediately caught so many throwbacks, it was an amazing nod to the works you've created so far

[samsquanch]

Gotta say man, I watch a lot of YouTube and your channel is easily the best. The way you film every single thing and narrate is top notch . Can't wait for the next one.

[Chef_PC]

I love the physical drawing planning of your parts. It’s so nice to see that old school technique staying alive.

[monty]

22:50 The way the.. more ..finished surface seemed to just magically appear as you passed over. It was beautiful.

[MisterBlack]

Not only are your projects very impressive, but the amount of them that you keep pumping out is borderline insane. I love it.

We built almost exactly the same flycutter back in the early 90's. Our shop made 100% aluminum injection molds for medium production jobs. Over the years literally thousands of mold plates were flattened and the flycutter machine marks were an unexpected source of cavity venting. Any errors in the machines quill bearings are grossly magnified in the resultant surface finish and I would modify the cutters leading and trailing edges to minimize chatter and wiping. It was a shared tool by all of the guys in the shop and I was the only guy who kept custom inserts. But. On an early morning start I installed the flycutter on the mill and started the spindle to warm up the bearings. Got a coffee and came back and started to run the HyVo speed sheaves through their range. At a high RPM one of the insert holders turned loose, shot out of the flycutter body on a trajectory that took it between my friend Gary's chest and his vise, across the shop barely missing the lathe headstock, , impacted my engineering bench sending papers flying up and everywhere, deflected up and through the roof. Please... never run these types of tooling at anything over 1kRPM's. And always check that the tool has not been left in an unsafe condition by the previous user. I used a pair of r/h cutting lathe tool holders. Careful setting of the 2 tools to 0/0 on depth and swing diameter really helps function, and balancing is also important, but only has to be done once. Hearing that slight ring of the cutter in this video really brings back memories for me.

When you inevitably hit 500k subs.

The box of shame should get a scrap metal challenge!

[doylerabjohn]

That a great tool you Now it will be great can't see you make the rest of shop tools, with your home shop tool you made.

[darjanator]

As much as I can respect you drawing all the plans by hand, I certainly do not miss it. I'm so glad CAD and especially 3D CAD is a thing now.

When I was a wee lad, I was told of the superiority of down milling. "What an idea, " I exclaimed with visions of recutting in me mind's eye.
So with me roughing strategy converted, I made a plan for the next visit to the knee mill.
Into the vise goes the block, with a 1" endmill into the spindle.
Touching off the part, I drop the endmill down to full depth and give the handle two cranks for a nice health .2" cut width.
I engaged, noticing how light the handle turns, then bam! The mill self-feeds until destruction.

only 8 views, I haven't even seen it yet and can guarantee it's some of the best maker content on YouTube.

[colonelangus]

My father taught Mechanical Drawing and Architectural Drafting for 30 years.Your skills and attention to detail are beyond commendable. I enjoy watching the drawings come alive as much as the finished parts. Bravo.

[Scyth]

New mark rober video just came out, but I'm totally watching this one first!!!
