Fly Cutter

[@MrHuntnfish]

Hey Matty .....good on you for taking a break, The Quorn would do any normal machinists head in, those that have started ( like me)...... and not yet finished know the road that you are travelling a bit like a drug addict, i'm guessing.... I have already drawn out your off the cuff 3" flycutter and will make one as well. Remember the old Italian saying "Rome wasn't built in a Day......But it did burn down in seven.....This is your build.

[@jackdawg4579]

Love your simple approach. Two dimensions i want to hit and the rest is as she comes!

[@metalshopwithtroy5755]

Great Work Matt, it's always a pleasure 👍👍🏆

[@johnmettler995]

Beautiful, piece of work. Thanks for the post.

[@MattysWorkshop]

Thanks for watching mate, Cheers

[@joeybobbie1]

Nice Fly Cutter Matty. The fit and finish you get on your work is amazing. It seems like everything you make comes out perfect. Really enjoying the Videos, Thanks for posting.

[@MattysWorkshop]

Gday, sadly not everything comes out spot on, I like the look of the shiny finish on tools and it really helps to prevent rust, really appreciate you watching, Cheers

[@daddysails8926]

Nice machine work,, and the mark is called a beauty mark🤙

[@MattysWorkshop]

Thanks mate, cheers

[@mchiodox69]

Making mirrors with Matty! Can't ask for a better finish than that!

[@MattysWorkshop]

Gday, I was really happy with the test cuts, super smooth, cheers

[@TheKnacklersWorkshop]

Hi Matty, Nice work... I quite like flipping for one project to another then coming back to the original one... See you on the next one, whatever it is... Take care. Paul,,

[@MattysWorkshop]

Gday Paul, I needed a change that’s for sure but I really need to get back onto the Quorn, thanks for watching mate, Cheers

[@TheMiniMachineShop]

Hi Matty, I did a lot of experiments making fly cutters. Cutting the groove off center causes vibrations, off balance, effecting the finish so I have my cutter on center and found 5 degrees gives the best finish using a triangular insert. Cheers...

[@MattysWorkshop]

Gday Dave, the Cincinnati mill is quite rigid, the finish felt very smooth and didn’t seem to be any vibration in the cut, the 2 other cutters have a 20° angle and I made the new one with a 15° to keep the mass done a bit, appreciate you watching, cheers

[@billchiasson2019]

Nice job on the fly cutter! It was obviously a success by the finish it produced! Well sir!

[@MattysWorkshop]

Gday Bill, Im really happy with the finish it did, thanks for watching, Cheers

[@paweisyn7446]

Thanks for sharing!!! 👍👍👍

[@MattysWorkshop]

Thanks very much for watching, cheers

Using a fly cutter to make a fly cutter. I want one of these for a decade.

[@MattysWorkshop]

Gday CàLem, i really like the finish the fly cutter leaves, looks better the an endmill finish, thanks for watching mate, Cheers

[@lawrencewillard6370]

I have no skill yet in metalwork, but making my own tools helps. Thank you for this..

[@MattysWorkshop]

It’s very satisfying making you own tools, much better then buying them that’s for sure, thanks for watching, Cheers

[@RetroSteamTech]

Another very nice job Matty 👍👍👍 Thanks for sharing the build with us. Cheers, Alan.

[@everlast2658]

Nice one

Cheers Matty, nice wee project 👍👴🏻

[@MattysWorkshop]

Thanks Terry, it was a quick fun project, Cheers

[@kimber1958]

Since my latest cock up, I’ve been a little put off. Seeing your video.simple tool done with great precision .you make it look easy .you have re-energized and motivated me to carry-on. God I love machining.

[@TedRoza]

Hi Matty. Very nice Fly Cutter well done from start to finish

[@MattysWorkshop]

Thanks Ted, I like builds where there’s no plans, appreciate you watching mate, Cheers

[@MG-xm3yv]

Nice clean cuts matty don’t see that to often, good onus mate

Thanks very much Chuck, cheers

[@bigalremington]

That was a nice build!

[@MattysWorkshop]

Thanks very much, appreciate you watching, Cheers

[@yvesdesrosiers2396]

Really well done!!! Way of building a fly cutter on the fly!!!😏 Thanks for sharing Matty. Cheers

[@MattysWorkshop]

Gday Yves, I like projects that don’t have plans, appreciate you watching mate, Cheers

[@AaronEngineering]

Top job Matty. You’ve got to be happy with those results mate. Works a bloody treat also. Cheers 🍻

[@MattysWorkshop]

Gday Aaron, apart from the mark from the collet nut it looks good and works even better, thanks for watching mate, Cheers

[@robertcorrie6737]

Nice job well done. Thanks for sharing the great content.

[@MattysWorkshop]

Gday Robert, thanks for the kind words, appreciate you watching, cheers

[@kentuckytrapper780]

Alsome job matty, excellent work.

[@MattysWorkshop]

Thanks mate, appreciate you watching, cheers

[@Warped65er]

Well done, and gives a damn fine finish. If anyone mentions that nick just tell them it's not for sale! Because anyone looking that close must be wanting to BUY it. LOL

[@MattysWorkshop]

Gday, might be an opportunity to make a few dollars there, thanks for watching, Cheers

[@AlfaSeven]

Really nice work Matty :)

[@MattysWorkshop]

Thanks very much, cheers

[@swanvalleymachineshop]

One day i will make one !

[@tattoos1988]

Fantastic video matty lovely fly cutter i prefer to try and make my tools rather than buy them I find you have pride in them and you tend to look after them more since I bought my lathe a few years ago I have made a few tools for my work as a mechanic and I have also repaired some of my tools that have failed over the years to stronger and better than when I bought them lol thank for sharing matty all the best mate god bless

[@MattysWorkshop]

Gday, it’s very satisfying to build your own tools, tooling can get quite expensive and I really enjoy using what I make, thanks for watching mate, Cheers

[@howder1951]

Nice job Matty, looks really nice. Enjoyed the build, cheers mate!

[@MattysWorkshop]

Thanks very much, appreciate you watching, cheers

[@hilltopmachineworks2131]

I knew you had some big insects in Australia, but that is one mean fly you got there. LOL!

[@MattysWorkshop]

Gday Tom, there big over here mate, Cheers

[@bulletproofpepper2]

Thanks for sharing!!!

[@MattysWorkshop]

Cheers Sam

[@ARIFINLATHE]

Thank you sir for the information

[@MattysWorkshop]

No worries at all

[@steveschumacher5470]

you just got the first dent right off, it was bound to happen anyway. nice work

[@MattysWorkshop]

Gday Steve, I wasn’t real happy when that happened but it’s done now I guess, thanks for watching, Cheers

[@jimsvideos7201]

Neat! I have some round bits in my bin of round bits, and I think there's a fly cutter hiding inside one of them.

[@MattysWorkshop]

Gday Jim, I’m sure there’s one hiding the somewhere, maybe a couple of different sizes, thanks for watching, Cheers

[@MrValhem265]

Come out Mint , Matty that dint is a Matty's Makers Mark lol :) cheers Bud take care.

[@MattysWorkshop]

Gday Robbie, certainly a makers mark, a one off I hope, cheers

[@RalfyCustoms]

Lovely stuff Matty, thats on my to do list 👍

[@MattysWorkshop]

Gday Ralfy, appreciate you watching and commenting, cheers

[@EverettsWorkshop]

I love the use of a fly cutter to make a fly cutter. My second and third one have better finishes than the first too! Looks good, and the finish you got on that test piece is nothing to sneeze at. Hope you're doing well!

[@MattysWorkshop]

Gday Everrett, I’m really happy with the end result and it works great, super smooth finish, thanks for watching mate, Cheers

[@frankward709]

very cool

[@MattysWorkshop]

Cheers Frank, appreciate you watching mate, Cheers

[@stevohdee8118]

Hey matty, nice build mate

[@MattysWorkshop]

Thanks very much Stevo, appreciate you watching, cheers

[@peterw8690]

Nice job again matty

[@MattysWorkshop]

Thanks very much, cheers

[@samrodian919]

Hi Matty just going through your back catalogue, here before Christmas 2022. Nice build, pity about the battle scar, but you know, shit happens mate if that's the only mistake you're doing well lol could you tell me the 12x12 bar and insert details please as they make a nice cut. I made a 55 mm one with a 3/4"shank as I've only got ER32 collets. I was doing great until I stuffed up and put the slot on the wrong side! It still works, I just run the mill in reverse. But I'd like to do a bigger one like yours. So that's a project for the new Year. Unfortunately it will have to be out of any steel I can get as 4140 isn't available over here and something like EN12 or 18 is so bloody expensive on eBay. We had numerous engineering firms around where I live in East London and there were a good few steel suppliers, but both the engineering firms and the steel stockholder all seem to have gone to the wall. Hey ho! I will get something eventually. Cheers Matty, Sam

[@MattysWorkshop]

Gday Sam, the tool I use in the fly cutter is just a cheap import, it’s a SDJCL1212H07 and the inserts are made by Drillpro DCMT070204, I hope this helps mate, cheers

[@pgs8597]

G'gay Matty.. Great build, thanks for sharing. Cheers Peter

[@MattysWorkshop]

Gday Peter, appreciate you watching and commenting mate, Cheers

[@ronmenzies362]

Hi Matty, looks very nice and a great finish on the cut. Is that a triangle insert that would normally be 90 degrees on the cutting edge if used in a lathe? So you have about 15 degrees overcut on the leading edge?

[@qzwqsy]

Very nice! What is your coolant set up?

[@MattysWorkshop]

Gday, this mill has its own coolant pump setup, I use Hangsterfers 5030 soluble oil, cheers

[@silverbullet7434]

Still the exact same way I made them fifty years ago. Only we didnt have insert carbide readily available then. I did use carbide tool bits brazed of course. Seem to me I used the type for cast iron on hard steel . High speed for everything tho. Momax and rex were my preference. Good job mate

[@MattysWorkshop]

carbide has made things easy but it can get expensive, thanks for watching, cheers

[@devemch7851]

Hi Mate! I love your fly cutter and need some. The finish is out of this world for milling machines. What is the tool and model number of the tool? It looks longer than a regular 1/2 inch cutter. I started using Iscar inserts a while back and I find them expensive. What do you use these days?

[@MattysWorkshop]

Gday, the tool I use in the fly cutter is SDJCL1212H07 and I use Drillpro brand inserts off eBay, there cheap but seem to do the job ok, I hope this helps, Cheers

[@Rustinox]

Finishing pass on the fly cutter with a... fly cutter. Good one, Matty. Did you figure out the connections for your motor yet?

[@MattysWorkshop]

Gday Rustinx, I haven’t worked the wiring out as yet, I really like the finish of a fly cutter, thanks for watching, Cheers

[@christophercullen1236]

It's called Bettina ! Old man from Queensland

[@MattysWorkshop]

Yep I agree mate, Cheers

[@BillyTpower]

nice result, why do you use a center drill in place of a starter drill?

[@MattysWorkshop]

Gday Billy, I use a centre drill simply because I don’t own any spot drills,, thanks for watching Cheers

[@marley589]

Hi Matt. Can you please explain why the tool is tilted at an angle, if it was flat to the bed the insert edge would still be the lowest point. I think cutting the tool on an angle is a leftover idea for when there were flat HSS toolbits. With the insert protruding beyond the toolholder body on insert tools you are using, is this angle required?

[@MattysWorkshop]

Gday, using an insert tool doesn't require an angle, one advantage is if you have a longer tool the the body of the fly cutter you can machine up to an edge/corner without the rear of the tool hitting, I hope I explained that ok, also with the inserts I use in mine if the tool was flat there would be more edge engagement to the material and possibly create chatter, Cheers

[@marley589]

@@MattysWorkshop Cheers Matt. It just seemed to me that all these new flycutter videos are making the slot at an angle because they all looked like that back in the day. This is where the angle gave natural clearance for HSS blanks instead of having to grind one side away to leave the cutting tip lower than the side of the blank. I see what you mean with the other end of the tool able to hit a shoulder when the cutting tip is out less from the body than the other end. This can be remedied by moving the toolbit out and moving the bed further away from the shoulder. The shape of your toolbit looks like it could not go back far enough to expose the other end enough to extend more than the cutting end. It's rare to use flycutters on anything other than a flat plane, rarer still, to create a sharp corner. The shallow finishing depth of cut is usually less than the tool tip radius, so the engagement will be the same, just on another part of the tip radius. Round button inserts are possibly ideal for deeper cuts for this reason ( and the cusps blend smoother ). Using tangential tip engagement is probably the most influential improvement to reduce deflection, impact chatter and ultimately surface finish. The homemade flycutters I have seen mostly use PCKNL toolholders laying flat. They use the unused obtuse corners of old CNMG inserts from lathe work.

[@jasonburns1407]

Nice 👍 How does the mist coolant system go mate are they any good?

[@MattysWorkshop]

Gday Jason, the mist coolant works good really, I did put a tap on the fluid side to control the flow a little better, cheers

[@araofmadisoncasey4247]

i never did see how the cincinnati table was reworked

[@jdmccorful]

Good work! You're helping us improve our skills. Thanks for the look.

[@MattysWorkshop]

Gday Jim, glad you enjoyed the build, cheers
