glad you and yours are well..

Good stuff James. I was thinking that if you are putting a threaded hole in the top for a jack bolt, I would bolt the rough casting to the mill table, deck the top, drill and tap, then mount the stand on a threaded arbor in the lathe and face the bottom to height. It's interesting to see different ideas as there are multiple ways to do anything.

There are limitless possibilities when it comes to work holding for sure.

Ya that brake rotor is bound to be some hard stuff. Probobly cast steel alloyed to be cast thin with minimal hard spots. and wow are you sure you had that spindle speed right . If suburban tool made it you know it's good cause Don Bailey aint foolin around. But to see it plow through mill scale like that. Hope you had a viking battle shield for those chips. ha ha great video

James, the hard spots in those castings are "chill", AKA "white" iron. The carbon there is present as ferric carbide, which can't be machined with steel cutters of any kind. The bulk of the casting is "gray" iron and the carbon is present in the form of graphite flakes. Powdery swarf aside, "gray" iron is a machinist's friend. Fast cooling, after pour, yields "white" and slow cooling yields "gray". Cross section size is a major factor in cooling rate. "Thin" sections naturally cool quickly.

I was also thinking of just taking the slot out of the casting to leave more material in that location, and maybe just increase the thickness of the base as well. More material to cut off, but it will be better material.

All my machines are 13/16 on the t nuts in the tables. The Carlton is bigger slot in the base. I will have to check it to see what it is for sure. I though it was 7/8 but it may be bigger. I will look and let you know.

That looks just like the wrench on my shaper.

I had an Atlas shaper for awhile and it had the same wrench.

I have an Atlas/Craftsman 12" lathe. The carriage lock, cross side set screws and lantern post screw are 5/16" square. The change gear nuts, banjo lock and tailstock nut are 11/16". I have the same wrench but all it says on it is "12". Same for 9 and 10" Atlas and probably the horizontal mill.

Great content. Very nice flycutter. Really like the fixture for the casting,nice work.

Great video. Nice fly cutter. Thank you for sharing.

That is a nice fly cutter, had a couple of those where I used to work, they work well. Thanks for sharing!!!

I might have to make a similar fly cutter to your one soon . Cheers .

Another video well done great comparison

Enjoyed

Thank you. That was an interesting comparison. We're doing well here in Germany, thankfully. Best regards.

Stay healthy, stay safe, and keep up the videos.

I think you would need a mill the size my Millrite mill to run that 11" fly cutter. LOL no great video. I've got a few of those Atlas wrenches for my lathe and but I think they will fit all Atlas shapers, lathes and horizontal mills. Again thanks for sharing, stay safe.

I was wondering why you didn't use that awesome flycutter in your last video, machining the jacks. Sure gives a nice looking finish, especially with the radius on that second insert. Cheers, Gary

James, I think Brian's big horizontal boring machine is the size for the "T" nuts or the Radial Drill

It is that, but man does it get the work done. Suburban Tool suggests running it 1500 rpm + for best finishes.

Very nice. Thanks for sharing. Glad to see carbide can do interrupted cuts. I've always shied away from it thinking I would break the inserts. Going to try circular carbide on the shaper eventually just to see what happens.

Round inserts are great, very strong. Choose your grade carefully, for shaper use

My take is that your mill is well-trammed, so the fly cutter contacts twice during a full travel. IMO the pattern from that second contact looks poopy, for lack of a stronger scatological term on a family channel. That is why I don't use fly cutters much, but then I have none large enough to finish cutting before the back side comes around. You are hereby guilty of causing me to begin the process of feeding my monster.

Enjoyed the video. GOD bless and stay safe!

Hi J, Gotta love the Suburban fly cutter. One of these days I am going to break down ans get one.

you might get away from hard spots with some pattern redesign.

@@jtkilroy lol i dont know about that. but I do believe its flow patterns and sharp corners, which is a problem on small castings. i think that a bigger radius on the main fillet might do the trick,. the metal is cooling before it gets to the end of the mould. get a second opinion, but I imagine a bigger fillet might fix it.

@EmmaRitson

risers and bigger flasks very rarely fix this. I'm pretty certain its restrictions in the mould. probably it would fix it in Ali or brass. not in iron.

Don't tempt Brian, if he hasn't got a machine those fit he might use it as an excuse to buy something that does.😉 If i was fly cutting those pieces i might be tempted to turn them 90 degrees so the cutter is in contact for a longer period, as a general rule it gives more time for the bounce to settle especialy on those ears. ATB c PS your namesake is doing well and eating us out of house and home, but worth it.😊

Those ends are cause by chilling after it was cast ,they cool faster than the mast of the part ,We called it (Chilled )

Unable to locate the punch holder mentioned in the video. Do you have a good link to share? Thanks!

James, did you consider drilling or boring the work for an arbor and turning it on a lathe? Sounds quicker than making the elegant casting you made to mount it in, though not as interesting. :)

@jtkilroy

I'm still considering it. Actually thinking of adding a core to the center of the pattern to make that easier as well.

Good video

Your “comparison” wasn’t apples to apples; your feed was much much slower on the second one and your spindle speed was much much faster also.....

That little wrench fits the tail stock locking bolt, and the square fits the screw on the lantern tool post of the Atlas 6 inch lathe. I've had mine for almost 50 years. Also, there is an Ontario CA (CA for California) are you sure it's not that one? Just wondering. ;-)

Why did you feed the second one a lot slower than the first, surely that could account for the inferior finish on first one.? 43 seconds for the first one side to other, 1 minute 20 seconds for second.
