So show us the inside!    That's the best part.

I started to take a video of the insides as i was repairing it. if there is really intrest, i'll finish that up and post.

If there is really interest? This is EEVblog! If there was any more interest we'd be in finance.

Not me i could never be in finance. Numbers make my brain feel funny and give me headaches, electronic insides however i can never get enough of.

Hi,
Today I found a rare connector:



It came on a short length of PTFE cable.

I found the datasheet here:

http://www.milestek.com/descriptions/productspecs/10-06030-231.pdf

These are hard to find, because there are very few of them and also because they look like common BNC connectors from a distance.

They are used on SMU and semiconductor parameter analyzers.

Isn't that a triax connector? For very low noise measurements. Like the one Dave has on his Atto Amps vid, w/ the Keithley 617 Electrometer.

Snip...

It is very similar. Just to add to the rarity of these connectors, there are several variations. The one on the Keithley 617 has two lugs, like a BNC. The HP 4155B has three lugs on the triax connector.

[bjcuizon]

Aaargh!    I didn't notice it had three slits ...sorry

[VK5RC]

Re the 'triax' connector, I thought the 2 lug was the older version and less common (often old Keithley - Fluke gear) , the 3 lug is the more common version now. In another post, an eevblog postee gives this connector its proper name I think 'TRB' , but it is also commonly called by the name of a common manufacturer as well, I think 'Trompeter'.
Fitting one is a long drawn out exercise - especially as you don't want to get finger grease and other impurities in the joint.

You are correct.
If you look for the keywords Trompeter, TRB and TRIAX they are easier to find but still expensive.
I have now a small collection of 2 and 3 lug cables and connectors.
Only my older Keithley 614 takes the 2 lug version.
The Keithley 2450 SMU and many modern electrometers like the Keysight B2987A take the 3 log version TRIAX connectors.

I like that front panel a LOT more than the front of my HP 3567A.

In other news, I bought a second, second hand lathe today. The only photo I have atm is the seller's, and makes it look horrible. Better photos and comments will follow once I get it home and cleaned up. Which will take a few days.

Oh dear, he's been using it for woodturning. 

A grimey lathe I bought a couple years back cleaned up real well with White Spirits, amazing how much better it was than other solvents.

What's the make TH ?

[TerraHertz]

That's what I assumed too, but no. It's odder.
Firstly, the owner is deceased, and was the father-in-law of the seller. But the seller knows something of the history. And the wood shavings.... wait for it... were sprinkled on it as a 'rust preventative.' 
Well, it would work if they were soaked in oil. But they are not. No real harm done though.

>A grimey lathe I bought a couple years back cleaned up real well with White Spirits, amazing how much better it was than other solvents.

It will clean up OK. All rust is light surface, nothing serious. Everything nice and tight, almost no play. The only real bummer is that removable section of the bed, which is goneski. Has never been sighted. But if needed I can make a replacement.
What I can't make, is the GIANT faceplate that comes with it. One of several different size face plates included, plus extra 3-jaw chuck and some other stuff.
I bought it for the huge faceplate, which I need for a specific machining project.

>What's the make TH ?

Ha ha... Damn, I was looking at the manufacturer's plate today, but didn't take pics (because I'd already decided I love it) and now I've forgotten. A well known old Australian brand, I just can't think of it right now. Not Hafco, not Sheraton.

It was listed for $1300, I got it for $500.  Had hoped for $300 considering the bad presentation, but 'the poor widow', etc. Not sure if I'm an arsehole or a sucker.

Btw, in the past I found White Spirits are a nasty nerve poison, when absorbed through skin. Kerosene is much safer.

Oops, just bought another Deckel for an incredible price 
https://www.ricardo.ch/kaufen/modellbau-und-hobby/werkzeuge-und-zubehoer/werkzeuge/werkzeugfraesmaschine-deckel-fp2nc/v/an935098816/
Have to fix it though, but it's a Dialog 4, so it should be easy.
Will pick it up in the next few days, can't wait for it.

So, what was the price? Can't work it out from the listing. Looks like a nice machine.
There are a bunch of large CNC lathes listed in Sydney for $1. The "PLEASE take it away!" price. I didn't take one of those because a) too big, can't transport and haven't enough space, b) Learning curve/time, and can't be sure I could get one working. Just need to do one simple (but large) thing. Asap.

Still might buy one someday, if only to play with. First need to solve the space issue.

[MadTux]

About 500USD or 450€.
Space is getting smaller at my home too, but it's a rather tiny machine and I couldn't resist at that price and distance (about 30km from where I live). It should also fit trough a 95cm door (perhaps have to remove x-axis or servo for that), so I can put it inside rooms where larger machines don't fit in. Here's a picture with human for reference:

Cool, that's much smaller than I thought from the listing pics. Very cute. About Au$620.
In what way is it broken and are you going to do a repair thread on it?
Do you have any source links of information on those?
Wonder if they exist in Oz? A CNC mill is fairly high up on my want list, but I'd assumed they'd be too expensive.

[MadTux]

Perhaps I'll do a repair thread, if it's an interesting failure. But if I'm lucky, it's only a couple of dried capacitors and/or dead batteries.

Here's the repair thread for my Maho 700, that I bought about a year ago.
. (Thread is in german, because most machines are found there, also easier to upload attachments over there)
https://www.mikrocontroller.net/topic/410520?goto=new#new
Almost took me a year to fix everything. Reverse engineered/redesigned in discrete parts a now obsolete and thereby expensive TCA280 and wrote an assembler for Siemens S5-010 SPS language because an EPROM had leaked in the PLC. Fortunately the source code for the PLC was included in the machine manual (good old times ) and I found the opcodes in the internet, so I was able to write (more like hack, my programming skills are horrible) an assember myself.

On rare occasion, with very good luck, one can find HGST enterprise He8 drives from WD external drives, but that requires really good luck, and apparently I didn't win the silicon lottery.

WD Gold were/are the HGST enterprise drives, I just buy them as is but for higher price.
With external drives you can encounter anything even 2x4TB drives stacked from any manufacturer.

Got this from the local small ads today
Voltcraft Dosimeter - Radiometer (re-branded Russian made RKSB 104)

Since I did not find any information on the device here on the forums, expect tear down pictures and some more in-depth information coming soon

I posted tear down pictures and some info in this new thread for those of you who might be interested.

Cool, it looks a nice size machine and seems to have quite a few accessories included looking at the pic.
Missing the gap bed is normally no big deal unless the gap is huge and the carriage can't reach over it. It's only an issue when turning something mounted on the faceplate where you need to get closer to the headstock.

Things that are easy to overlook and leave behind are:
Chuck keys
Tailstock chuck (and key), dead and live centres, tooling and steadies. I see the tool post on a shelf and there should be the key for that too.

It was listed for $1300, I got it for $500.  Had hoped for $300 considering the bad presentation, but 'the poor widow', etc. Not sure if I'm an arsehole or a sucker.

A unit of that size and condition costs to get home and clean up and as you didn't have any competition others also thought it was too dear @ 1300. Take real care shifting it, they're top heavy and real heavy. My guess for that unit will be ~1 tonne but surprisingly easy to move once it's on pipe rollers.
Check this for advice on lifting it and make a sound plan so no one gets hurt:

Btw, in the past I found White Spirits are a nasty nerve poison, when absorbed through skin.

OK, so that's what's wrong with me. 

White Spirits is just low octane petrol......without all the nasty muck added to boost octane.
Tiger Moth planes and early tractors and cars ran on it.
It doesn't stir up the skin on your hands like modern petrols does.

To be entirely fair wood shavings as a rust preventative may not work however it does make sense in that the wood shavings soak up water to a limited degree. The problem with that logic comes when you consider that wood simply cannot soak up all of the water even if it did then you just have wet wood shavings sitting on metal and as you said with no oil it is highly ineffective.

[TerraHertz]

The problem with dry wood shavings on oiled steel, is they soak up the oil. Leaving the metal unprotected - and in contact with wood, that tends to attract moisture too. As well as being a bit acidic sometimes.

I'll have more pics tomorrow, hopefully. Arranged to pick up all the accessories then, lighten the machine where possible, measure for transport, etc. And if I can remember this time, will be able to tell the brand and model number, instead of looking like a fool.
And btw, I've already been told to NOT remove the headstock.

Tautech thanks for those links. I should send that guy pics of my old Sheraton model A lathe, since it seems to be a pretty early one, and he asks for them.

I knew that about wood shavings though, in my opinion, it is definitely interesting to hear both sides even if one side is in error. That being why i said anything about the subject of wood shavings on metal to begin with.
