It sounds like you got it right to meI put dro's on my lathe and a homemade yuriys bluetooth, when I go towards the chuck I get negative reading, and when I cut dia. away from me I go negative is that standard or do I have it reversed???
Good jobA quick small job.
Wanted to fit a lens onto an astronomical camera (http://www.myastroshop.com.au/guides/gstar/gstar-ex4.htm) for a friend.
My first attempt relied upon the expert who knew all about these cameras (not myastroshop) who told us it was a metric thread and checking it out with my thread gauge it appeared to be a 0.8mm thread which I duly cut.
Hmm, must have cut a taper thread as the lens only screwed in half way before binding.
I dug out an sae gauge that I've never used and double checked the original thread, hmm, it looks like a 32tpi thread also fits.
So I bored a hole and cut the 32tpi thread. Success, it screwed in all the way.
I made a mandrel and screwed it on so I could turn it to size and cut the outside 32tpi thread. (it did have the centre in place when I turned and threaded it)

This is now a wide angle camera.
This was the very first non metric thread I've cut.
Good jobTook more than 1 day but I made a holder for my plasma torch to cut wheels on my positioner. I was cutting the wheels on the mill with a slit saw and was taking waaay to long. This way saves me hours per wheel.View attachment 239836View attachment 239838View attachment 239839View attachment 239832 View attachment 239833 View attachment 239837 View attachment 239835View attachment 239834
That looks greatI bought a couple of those harbor freight tool boxes a couple months back, one of them i placed between the mill and the lathe. I figured i could put the tooling for each in it. It quickly became a bit of a mess to work on it and use it for tool storage. So being i have some time off from work, im taking advantage of it by taking on as many of the shop problems as i can.

Tool holders all in place, I made some boxes and covered them with aluminium diamond plate, the right side will be for lathe tailstock tooling. The left side will be for tooling for the mill. I plan to make a couple dimple dies and punch out the sizes I need in the diamond plate. I'm pretty happy with the way everything has come out so far.
The laptop computer is used for some pipe bending software, converting my old manual tubing bender to hydrallic/Air.
Thanks for dropping by.

Haven't watched any TV for at least 5 years. Just eats up too much time. When I do have some downtime, I'll read a book.
OK, end of rant.
