That's a nice job well done! Always love the finish you get on 4140 (or 4340 as is the one I can easily get) - and as you demonstrated, you need to make sure you take decent cuts. Being feeble and taking light cuts, not so nice finish...

Gday, heavy cuts are the key to a nice finish but it takes a bit to get the chip to break, cheers

I can see the urgency of pressing them in as the surrounding metal is shunting the heat into the freezing cold bushing making it fatter faster!

[@ronwilken5219]

Hi Matty, for your oil/grease grooves look up that young, I think Philippino machinist who works off the floor with the most basic of tools. He produced an attachment for the tool post on his lathe that while the chuck turns the work, via pair of beveled gears, home made, and a Conrod like an engine would use, the tool gets moved in and out of the bushing producing a perfect "X" groove that doesn't exit the bush thereby keeping the oil inside the bush. I'll see if I can find the link. Otherwise, thanks for posting. Greetings from Canada's banana belt. 👍🍌🇨🇦🕊️🇺🇦🤔🇦🇺🤞

[@MattysWorkshop]

Gday, the wheel cylinder hone works a treat, thanks for watching, cheers

[@tiredoldmechanic1791]

I've never liked pins with grease holes in them. They always break at the grease hole whether it's halfway through or all the way. I try to convert to greasing the bushing bore. I've converted many pins to external threads on one or both ends because I've seen too many with cross bolts or end bolts shear off the bolts so the pin comes part way out. It also helps to keep the flanges from spreading. The machines aren't designed for sideways pressure but the operators never seem to know that.

[@MattysWorkshop]

I have seen a few pins break through the grease hole but they wanted to keep it the same, thanks for watching, cheers

Hi Matty, Up with Kurtis of CEE now!, soft bushes and shafts should last a bit if he's only using it occasionally, what was the material? Yes, I've seen those mini diggers treated like a 30 tonner as you say, especially hire ones. Brilliant job, and great photography 👏. Thanks for sharing.

Being that today is day 4th day of being hit with the covid freight train, watching was better than all the meds they put me on to get relief (@@)! It's always a learning experience to how you tackle a job . The boring head,,,was that the one you made a few videos Back? Taught from our youth to freeze pressed parts as a trick of the trade, but Kurtis at CCE using liquid nitrogen has always got my interest. Have you experimented with it's uses? Bear

Gday Bear, I hope your getting over the Covid and your sticker will be in my next video, this is the boring head I made a while back, I need to make a new adjustment screw for it but it has worked flawlessly, it’s been put to the test many times, I’ve never used liquid nitrogen before but it’s great stuff, Thanks for watching and commenting mate and I hope you feel better soon, cheers

[@andrewwells1386]

Love the videos I was always taught to run coolant when parting off as you generate a lot of heat which usually causes the metal to expand and grip the parting tool and may give poor finish to the part
