Just completed this VFD control system and getting ready to ship it out, always seems to take longer than I think, but nice that it is done. This is a more basic control system build with controls in two pods. Forward, Stop and Reverse switches are all momentary and interlocked. In this case the control board is mounted in the VFD cabinet, the breakers are for the main power in and two duplex sockets. Separate power is supplied for 12 and 24VDC.

I like that design, nice and simple.
 
Nice may be simple to some. Yea, I need to learn some of that electronic stuff, Normal contact, and things like that OK, But all this other stuff, I have not got a clue .
 
Knocked another latch component out for a friend who is having the same issue with his Black Box. Thus will give me two in the field being tested.

Machining the last flat on the minor end.

Two completed and ready to install them into the latch bodies and install in the boxes.

A 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.

IIRC, small TV lenses are "historically" 1" x 32 TPI. I occasionally designed TV camera based optical systems while at HP. Glad you got it figured out! The entire proliferation of English/metric is frequently irritating, especially when you have to mate unrelated components to each other ... and then if you're an auto buff, you get to deal with Whitworth and maybe even BA. Ah, well ...

Thanks Randy. I will have to check it out. I thought the whole purpose of Tapatalk was to be able to load pictures easier but for some reason all I see on my PC are red X's. On Tapatalk just fine. On garagejournal both Tapatalk (iPhone) and PC are showing the same.

I made a tool for drilling new dowel pin holes on the back of my VW crank. Ended up someone else needed it more than I did as he had a problem with his daily driver. I gave it to him to test and am waiting to see how it worked.

I know there is a commercially available tool out there but I didn't buy all these machines to buy stuff from other people :)
