Sir,

What do I need to ask for to get the threading and centering gauges from Starrett? How many in a set? Amazing instruction....looks like you just couldn't help teaching after school.

@poolfool31021 Buy this or an equivalent. Starrett 392 center gage

Hi, tubalcain, i have a question, if i am making a metric thread on the lathe do i need a thread chasing dial? or is there a different method?

[mrpete222]

@PayneKiller23 Yes--you need one.

[mrpete222]

Need to calculate

Thank you for the ENCOURAGEMENT.

I am just getting into working with a metal lathe. I'll bet most of the comments come from people with way more experience than me but I wanted to post and say how much I appreciate the work you must have done to make these videos. I know you can't help that you make it look so easy. But you do it in a manner I can play and re-play and (I hope!) eventually master. Thank you so much.

Internal threads on an engine lathe are normally cut from inside to outside with the spindle running in reverse and the compound set in the direction of the cut. In the case of a CNC turning center where you can thread from the inside to outside and stop precisely it is normal to thread so that the spindle doesn't reverse when other ops are machined.

skills for life everyperson should know. if everybody had access to machines like this usa would be back on top of manufacturing.(oh wait a minute we still have 30% of all durable goods manufactured on the planet making us still #1 hahahaha) #2 is not even halfway there.

Excellent, good sir.

Nice Job! Hiram Abif would be happy with your mastery!

[wongsol]

I could watch your instructions all day. Keep up the great work!!

[ginsboy2003]

Awesome job on the video, I need to watch the rest that you have. I'm self taught for what little I know and have yet to cut a thread. I have made a bullet mold though and have videos on that.

[jimbrady1776]

Very nice, thank you. I am reminded of my metal shop teacher 40 years ago. Been a while since I did internal threading, but am about to head out to my shop and give it a refresher.

How simple it is to talk about and understand threading when you are using the metric system. You americans should try it out ;).
