MK 5 turret retainer

[Jimmer]

Perhaps its being machined on a manual lathe. From a CNC standpoint, the computer is essentially just telling the tool how far to move per rotation of the part, hence why I'm surprised that there would be any difference between metric and imperial threads on a CNC.

Very good.

Sound like pretty normal fairdinkum answers.

Herbie was a drunk bloke that had an Aquarius and a tank and some weights.
And I had goggles with two bits of glass, snorkel and flippers, real flash Nemrod stuff,
after the Coles Store green rubberised plastic ping pong ball stuff, but no weeks wages
wetsuit. I suppose that means wetsuits haven't changed much in price, sort of.

So we would go out drunk, on his boat, he made more than a weeks worth in a week, and he was happy to be drunk, fishing, spitting on his bait for luck
and I was happy to be sober and using all his stuff
that he never used and never got back
going "Supervised Diving."

Quite happy to be looking at sand and getting scallops for lunch.

But then I got scared, not scarred, thinking about physics and how tough
everything would be, when I finally signed up for a course in 1976.
Size and vintage hey LeadTurn_SD has played a big part in development.

Well anyway we used a couple of Drager twin hoses only to indicate method and performance because by then the single hose had well and truly taken over.
The real modern stuff. Even in 1976 we laughed at, and pooh pahed the ancient
junk. Even the instructor was ancient and Marty is about 55 now, real ancient.

I came across one of those actual Dragers accidentally 10 years ago and bought it.

Enough already.

awap. I was scratching around in "that box" again looking, because my
measuring stick seems to have welded itself to one hand and a key to the other.

The SP din into reg thread measures .610
The Poseidon Cyclon measures .500 which will leave plenty meat between
a threaded inlet hole and the ambient hole on an SP Mark 7 conversion.
And it seals on the side, not the end.

I'll find something to make a picture.

Anyways, thanks, I'm off to guess some torques and punch some seals
and try and remember how to reassemble a forty five year old EX military
EX police inverted twins single hose reg that looks like something that
should live behind a fill panel than on tanks. Gotta stay outta "that box."

And again.

My sockets are ground flat, no chamfer.
Both fit in the cap with room to spare, not much.

The 17mm socket on a 17mm bolt turns about 2mm before engaging.

The 11/16 socket on a 17mm bolt turns about 3mm or so before engaging.

The 17mm socket will not fit the 11/16 bolt, just.

Some more news from the machine shop:

• It'll be grade 304 stainless steel
• There's an extra charge of 15 euros for tooling to cope with the imperial thread, or .3 euro/.4 USD each
• The head (hex part) will be 17 mm instead of 17.46 mm (11/16") for some unclear reasons. Arnaud thinks it'll work with a 11/16 socket. Can anybody confirm/approve?

Regarding the through hole, I think the consensus is .160". Can I confirm it or shall we leave it at .165" as per the original drawing?

The 17 mm hex is fine with me.

I would go to 0.160". A 4mm drill bit would be close enough IMO.

Howdy all. For some reason I wasn't getting the updates about this thread and lost sight of it. Thanks to Couv for sending me a reminder.

Yes, I am still interested in getting 4 retainers if possible. Cheers!

Welcome back oceancurrent, just in time.

Last call for all standby passengers to France: please proceed to check-in. I'll confirm the order sometimes tonight CET, and we'll talk about logistics next week.

At this time, we have 52 pcs.:

knowone: I assume awap has failed to convince you the MK5 is the ultimate first?

 

[Texfrazer]

Well Zung, all of my beautiful plans to come personally pickup the parts have gone to the birds.

I had found $365 flights from NYC to Geneva in late Feb/early March. Unfortunately, the wife reminded me that we have committed to a weekly commitment for 7 weeks during that time frame.

Ah well. Looks like you'll get to ship another round out.

The wife did say that I can act as USPS.

 

[Zung]

That would be a very expensive courrier service, even thought the flight is the cheapest I've seen for some time.

Now the ugly part for all of you:

• Per unit price: 7.90 euros
• Quantity: 52
• Postage to Switzerland: 19 euros
• Total price FOB: 429.80 euros
• Reimbursement of PayPal fees to the seller, 3.4%: 14.61 euros plus .25 euros
• Postage to the dispacher in the US, insured: 15 euros
• Total landed price: 459.66 euros
• Per unit landed: 8.82 euros or about 11.75$
• On top of this, a buck or two for the postage to your individual addresses

That'll be about $13 a pop, depends on the quantity you want.
OK?

 

[redacted]

OK by me. I'm not going to tell her.

 

[oceancurrent]

No problem.

 

[LeadTurn_SD]

OK by me. I'm not going to tell her.

Ditto. Sounds good.

And I promise not to tell awap's wife either.

Thanks again Zung.
