Advance METAL LATHE- boring steady rest facing
by Lathe on May.14, 2009, under Lathe Videos
Shows set up and machining of pipe in preparation for using a steady rest. Filmed in our shop Oct 2008. This is a project for my home–(Trying to keep the vehicles off my fence.) Keaton Morris assisted me, he is one of my machinist students. This VDO is a rare posting of advanced techniques. I will not be posting many of my advanced vdo’s– those are for vantech school use only. This VDO is here to entice those to become a machinist. Knowledge of Set up and operation is what makes machinists …

it’l push the tube out of round the way you explain, it will also have a smaller contact area for grip. if he chucks external he has spread the load . then use a boss with a shoulder down the end bore with a live centre for axial pressure application into the face of the chuck.

critic the guys good teaching? you clearly know little about speeds. i’d like to see your video with added speed, i need a good laugh.
i think you are doing a stirling job teaching the students, keep it up.

A quicker, better, and safer way to cut the O.D. is to grab the inside of the pipe with the 3 jaw chuck. Tap the outboard running true as you did and then make your O.D. cut near the chuck.

The feeds and speeds= STUDENT SAFETY- It is best to be conservative in this approach. Crashes happen when students do not have experience on processes. Several other factors are tool geometry and radius of the insert, this dictates speed. In order to reduce vibration I have slowed the speed and reduced the feed. I need a good finish or the turned steady rest area would damage the roller bearings. Similarily, the bore begins with an intermittent cut because of the weld seem. Thanks

I’d have faced one end as square as i could get it and then turned the part around so the square end rested against the chuck. This adds rigidity to the setup. Also I’d use high speed steel tools to face and cut the place for your rollers as you don’t use as need pressure to cut.
Loved the video, good work.
