Great to see you back, James! We've missed you. Thanks for another excellent video.

[@captcarlos]

What a bloody magnificent example of whatever the puck it is! Good to see you back James. Missed ya.

You do not what that thing chasing you around the room, keep those clamps tight. Have a wonderful new week. Charles

Good to see you back JP

[@AllJustOnesandZeros1010]

good to see a video from you again. I hope all is well.

If you can get forging shot blasted first it will help save yoyr inserts from the oxides

[@Exer12432]

Nice video as always. Can you do more broken tap removal videos with EDM? I always liked that.

[@jamespark_85machiningtv]

All right. I will upload it when I get a chance.

Hello! Nice to see your work again!

[@tomredmond]

I have to agree with the rest of the commentors, Nice to see you post a video again.

[@Xris-FJ1200]

Hello, many thanks for this new video A little bit longer for the next one ?

[@jamespark_85machiningtv]

Okay, I get it. I'll try that!

[@dmill6668]

Good to see you back!

[@bobbiac]

Wow looks like it's less than half the mass it was when you started

[@10Mbowman]

good to see you again mate!!!!

[@jamespark_85machiningtv]

Thank you so much!

Very nice👍

[@寶寶-n8m]

You are back buddy 😊

[@GICK117]

Awesome. I am sure these mini sized parts needs lots of TLC. LOL!

[@jayhammersley9534]

what's the reason you didn't use the 100 degree edge of the C insert for roughing?

[@parnuzutech]

Listen... Process machining

[@CraigLYoung]

Thanks for sharing 👍

[@jasoncohn3944]

Too bad the ram doesn't fit inside the bore, then you could just program to the other side of the bore and run the chuck in reverse.

[@gj91471]

Which insert / grade?

[@jamespark_85machiningtv]

The insert manufacturer is TaeguTec. and grade is TT8125.

you have a big problem wuth the chatter, in that grove

[@jimmytwizzle7836]

God that that exciting.

[@johnallen7807]

Fascinating process, just wonder why the casting could have not been shaped more to reduce the amount of machining?

[@jamespark_85machiningtv]

Cast iron has lower mechanical properties and more defects than forged steel.

[@johnallen7807]

@@jamespark_85machiningtv Yes I know, I just wondered about the mould shape.

[@alexdavis7357]

No casting involved. Just a giant block of hammer forged steel with a hole in it.

[@canonicaltom]

Making a specially shaped forging is much more expensive when you are only making one part.

[@Youtubehandlesaresilly]

It was forged, not cast - and forging is very difficult to do precisely. It needed a lot of ‘extra’ so there would not be a dent or something somewhere that would mess up a critical dimension. If there is a lot of something being made, then it’s possible to use precision dies and it’s not so bad. They cost a lot of money to make though. But even then, any bearing surface or interface needs to be machined.

had to downvote, vid is way too short.
