Hobbyist and a retired engineer and possibly a test equipment addict, though, searching for the equipment to test for that.

That looks sweet, blueskull. You must share your impressions after driving it around the block a time or two.

Heil HM-10 Dual
I got some great help from Donna at Heil support on how they originally mounted the elements.
after some very nasty cleanup and reattaching the elements it works and looks great now.

Nice sleuthing, blueskull. I've had success with Arrow overnight. Their search needs a major overhaul, though.

You should be well proud for your efforts there buddy! It's went from looking done over to brand new with your clean up! Really nice job!  :-+

And this Keysight scope actually uses a LeCroy ADC!

Very interesting (that LeCroy has their own ADC and that Keysight is using it).

Thanks, it is very satisfying to bring something back like that.

Sold a few bits and pieces, got paid for a few jobs - spent all of it plus a bit and brought a Drone  >:D



There is rumors of a new DJI Pro 2 all round the net but this one was a very good price (only until the end of TODAY!) for those of us downunder given our value of the AUPeso to any other currency and the 10% Tax  https://www.ebay.com.au/itm/DJI-Mavic-Platinum-Pro-Fly-More-Combo-32gb-Sandisk-Extreme-Micro-SD/202346019746?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

New chip ordered, hopefully Arrow will get the "free overnight" done right.

I ordered 3 part numbers from Arrow (2*Vref, 1*iMX6ULL-500MHz, 1*iMXULL-800MHz, totally $22 after SUMMER10 coupon), both from Reno warehouse, and they shipped out in 3 FedEx Overnight packages...
How can Arrow possibly be making money :-//.

Yeah, I don't get it either. Most of the time my order gets split up like that. It's kind of crazy, but I figured their logistics must be optimized for very large orders, not small ones like we make. Beats me.

Just some extra tools:

- an adjustable torque wrench for SMA connectors. Claimed to be adjusted to 1 Nm, tested with an torque indicator and they did a good job.
- a crimp tool for terminal connectors.

Wow, do you have a picture? That is an interesting curiosity, as I thought LeCroy makes their own ADCs (and sample memory ICs, MAMs, as well).

From this picture I only see e2v ADC, but e2v is rather unrelated. They got acquired by Teledyne last year, but it is the only thing they have in common with LeCroy I'd guess.

I didn't know they got recently acquired. I thought it was a long established LeCroy business unit.
Not exactly recent. Teledyne bought up LeCroy back in 2012.

Much less delicate than microphones and scopes, but still electrical-related. Two socket drives, the 'small' one 36mm , and a 48mm extended length impact socket. Both 3/4" inch square drive. The 48 mm one I promptly cut in half with an angle grinder, because I need to 'extend' it quite a lot more. It will have a length of steel tube welded between the two parts.

These are for disassembling the big old 3-phase motor that came with my recently bought large lathe. I can't start on refurbishing the lathe yet, but I do have space to do the motor. It was made in the early 1950s, and looks like something out of a 1920s Amazing Stories (early SciFi) magazine illustration.

The shaft nuts that need removing are of course imperial sized, but I refuse to buy imperial wrenches. The metric ones fit well enough.

Open frame (ventilated) 6 pole, yeah they made them big back then.

Gunna spigot the 2 socket parts THz ?
That'd keep alignment good and it looks better too.....like you know what you're doing.  :)

Interestingly, that sheet metal mesh outside around the end vents, is spotwelded to the cast iron endpiece. I didn't know that was possible.

If I knew what I was doing, I'd probably know what you meant by 'spigot'.  :)
Do you mean cut a lip in the faces on a lathe, to center the extension tube accurately? And chamfer the weld seams? I will be doing that. Just haven't found/bought a suitable bit of tube yet, so don't know dimensions.
Alignment will be by clamping the parts in a bit of L section.

In the motor, the windings/pole piece seems to be fixed in the frame solely by heat-expanding the frame onto it. I think I need to separate them for a few reasons, so heating the frame up (without wrecking the old windings) will be a bit nail-biting.

Edit to add: The plate says the motor is Y-wound, and there is no Neutral. Any one know if this is a problem for variable frequency drives?

Btw, did anyone else catch that company name on the brass plaque?

Yeah, pretty much exactly that. Some ordinary 2" black steam tube or the bit thinner wall galv water pipe should do the job. Either is just over 2" ID with 2" indicating nominal ID not OD.

I'd resist trying to separate them after being shrunk on. What's making you think you need to ?

Wanting to sandblast the frame. Also access to punch out the pins securing the brass plaque, from the inside.
Still weighing the pros and cons. Needing to heat the entire frame circumference evenly, to avoid risk of cracking the cast iron, being one issue. Doing it fast enough to not significantly heat the pole piece and aged winding insulation, another.

Being cast, it's not like it will rust away anytime soon like if it was steel. Hit it carefully with a flap wheel or a cup brush, smear some grease on the brass plaque and slop/spray some paint for decoration on as like I said cast ain't gunna rust away anytime soon.

For the socket tube, another thought.....diff axle tubes can be fairly thick wall tube if you have some of that sort of scrap lying about.

"Lancashire Dynamo & Crypto Ltd England"

Sounded like an odd combination, but it seems Crypto was just the name of a relatively ordinary electrical company which joined with Lancashire Dynamo & Motor. Apparently no top secret codes or anything like that were involved.
