We're not too far from or local airbase and a couple of decades ago they were doing tactical jumps from C130's @ 20,000 feet and gliding some 15km back to the base when one of their instructors had chute malfunctions (backup too) and was lost on neighboring farmland. We saw some guys chutes that tried to stay with him and jumping on our bikes to go and see what the fuss was about and stopped on a prominent ridge when a couple of Hueys came over our heads @ warp 10 speed. Gave us quite a fright.
Anyways the poor bugger was lost and his radio beacon never went off so it took the RNZAF and army a couple of days to find him.
Meanwhile we had a full command post in the flat paddock right behind the house.......truckloads of ppls combed the countryside looking for the poor guy that had some 900 jumps behind him and left a wife and kiddies too.  :(

Think it put me off ever wanting to do a jump.  :scared:

Yeah won't get me jumping. I'm no taker of unnecessary risks myself!

On that subject actually, people and bits of planes fall out of the sky occasionally here. I was told last week that a person landed in a colleague's street over in Sheen a few years ago and one went through a roof in Richmond. We had a chunk of metal land in the street up the road too which appeared to have come off a plane :scared: ... living near a large airport in a desirable location has its disadvantages.

Life is tragic in some cases  :--

There's a parachute club not more than 5 miles from here and it's common to hear EMS calls for busted legs or someone hung up in a tree. But every once in a while there's a splat. I'll let you guess what that is.
When the daughter was doing her pilot training 'jumpers' were referred to as meatballs.  :-DD

Quote
They use a dehaviland twin beaver as their jump plane. Jump height is 10K feet. And before the jumpers even hit the ground that twin beaver has landed. Practically at straight down dive.  :scared:
The dive from 'up high' is a carefully monitored event so to not cause damage to engines from too much cooling.

Yep, must be country restricted. Sorry.

Nothing like the sound of a Huey coming at you.  :-+

Well, perhaps a bunch of them are better.  :-DD


@med, there's something wrong with your link, its not working.

Really? Working fine here. Anyone else having a problem?

Edit, maybe it's country restricted?
I don't think its country restricted since I can actually find that self same video on YouTube and watch here in the UK?

Housedad - thanks for the find - I forgot about those guys - a great old TEA resource.
Thanks others for the comments - I must be getting stronger (underestimating its weight) - TEA weight training! HeHe!
I will have a go at grinding down a USA cable 1st, with a layer of heatshrink and a ground clip for added measure. Currently about 1M ohm between either mains leads and the chassis.

Rob:  I checked out Surplus Sales of Nebraska and they have a socket that looks like the same on that RF generator and they might have a plug to fit.  Give them a call.

Here is the web page:
https://www.surplussales.com/Electrical/ElecAC-2.html

Not the same receptacle. That's an early non-polarized AC connector for use with double-insulated equipment. It's got the slots centered in the connector, and is approx 30mm diameter. Unless my eyes are playing tricks on me, the socket on his generator is approx 20mm with the blades offset from center. This is a polarized connector.

Mnem... It's hard to know without a 1955 twin lead only usa cable mount socket - the surplus sales socket will need a bit of bodge-ing - it looks too big as is but it is closer than I have at present.

If it jams, force it.  If it breaks, you needed a new one anyway...

2 minute teardown

Airflow Instrumentation LCA6000 Airflow meter.

Socketed IC's  :o Hand soldered board complete with flux residue splattered everywhere. Seems to have been my week for disintegrated foam  :palm: Very little inside of real note other than it has a coarse and fine trimpot for Calibration should I ever find myself near a known source. Gentle exhale 200mm away from the vanes spins them up easily.

PP3 clip in battery holder going on the printer soon to be held down by the thoughtfully provided LCD screws.

Worth everyone of it's $5 AUpesos.

Well, it's easy enough in person to measure the diameter of the socket in your front panel, and while you're there with a straightedge, determine if the blades are centered in the cavity or offset. If it's ~20mm and the blades are offset from center, then you pretty much need a US AC extension cord like the one on the left. This you can easily carve down to fit safely in pretty much any socket of this type, BTW.

Alternately, you may be able to find one of these SJO 2-Wire NEMA 1-15P Power Tool Quick Lock Cords. IIRC, the twist-lock is easily cut off leaving a 2-wire socket pretty much perfect for this. Back in the day, canister vacuum cleaners had a cord with a similar rectangular molded rubber end that was approximately 1/8" larger than the two blade sockets themselves. They outlawed these ages ago, though.

Looking at that one from Surplus Sales, I expect that unless it fits correctly exactly the way it comes, you're not going to be able to grind it down without destroying it as a connector due to the way they assemble.

Good hunting,

mnem

Definitely looks much better made than my MasTech from Shenzhen. I'd have jumped on it. Hope your seller isn't too butthurt. ;)

Hello, thank you for your purchase! I will get your item on the way shortly.
Kind regards,

Here's an off the wall question for the TEA crowd: what's your favorite nonconductive adjustment/alignment tool(s)? I'm looking for some that don't end up twisting and breaking like the plastic ones I have.

You should be able to find these for a relatively small amount of money on eBay:



Search for "ceramic screwdrivers". Being ceramic, dropping them on a hard floor is not advised!

I've had one break recently too :( OTOH my one from RS hasn't broken :) But is it still available after 35 years? :(

Thanks guys, the internal diameter is 25mm, the male connectors are 12.5mm apart from each other and centred in the hole, they are equal size at 6.3mm, ie all non metric. Is this is the old USA standard? (it was made in 1955).
 I think I have found an iec chassis 'plug'  that will fit with minimal /no panel work - if not, I will try either a cord bodge or a mock replacement mini-panel with a fixed cord - strain relief etc.
I will have to wait for bits to turn up in the antipodes!

It looks a lot like the connector in pictures 5&6 would fit, on this useful site for old electrical fittings;
https://www.plugsocketmuseum.nl/NorthAm2.html

And why didn't you measure it in inches, I have checked a modern US cord I have here and the blades of the plug are 1/2 inch apart (12.7mm) & 1/4 inch wide (6.35mm).
