Thread: Large Crane
05/04/2020 20:14:39

Did a contract in early '90s in Rotterdam on the 17th floor of an office building overlooking the quayside on the Maas.
The SmitTak floating crane barges would occasionally park outside the office and we would watch the crew shimmying up the ladders to the jib? boom? tops to grease the pulleys - we had to look up at them overhead from 17th flr.

There you go Michael **LINK**

These are taken 25 years ago - I have digital copies of these but on old zip disks I can no longer read. Apologies for the photo quality, I used my mobile phone to photograph existing printed photographs.

All these are organic microfossils. These are dinoflagellates, foraminifera linings, scolecodont and plant spores from the Cretaceous chalks in Ireland and from oil exploration cores in the seas around Ireland. Plus an acritarch from the Silurian in Shropshire. […]

.

Many thanks, Andrew ... I was immediately intrigued by the acritarch : not only for its appearance, but because the word is new to me. /snip.

.

Many thanks from me too, Andrew. Any day when one learns something new is a successful day.

I think that photo is a big block. It even has a hi rise & 4 barrel. I want one.

Steve.

Could be a 454 just like the one in my '72 C3 Vette out in Saudi (that one's a bit shinier than mine was )
Left it behind 'cos 9mpg would be a bummer in UK, was OK at 17p a gallon, cheaper than a bottle of water.

I can recommend investing 49mins watching this youtube film - **LINK**

Follows the manufacture by a Rolls-Royce owned German company of a 13,600hp 20cyl diesel engine, one of four installed on a SeaCat ferry btwn Malta and Sicily.
Shows the whole process from casting the crank-case through to in-service with good engineering insights.

As a professional boiler maker I have been self isolating for several years with no sign of any change. And whats with the loo roll....your more likely to end up constapated than the other way round?

In a panic situation, logic is the first thing to go absent
Previous panic episodes, bread/petrol/sugar, and now loo-rolls. I despair.

Thread: Spring's a-coming
29/02/2020 20:58:36

I know the storms in UK seem to be never-ending but the fig and cherry-plum trees have been in blossom here for two weeks now. Best of all though is that yesterday mid-day MrsD called me outside to see and hear the dances (I cheated and looked it up = herd or dance ) of cranes flying over on their way to North and North-east Europe. They always stop over our village, wheel around before re-forming into V's and heading off North again.
They know better than the forecasters when Spring's a-coming !
Hope you all are keeping your feet dry in the workshop.

snip/ My biggest problem these days is that I sometimes get the shaky hands. Never a good condition when trying to do delicate work. Soldering fine wires was a problem until I made a small hand rest to keep my hands steady./snip.

Dek, I have seen a suggestion for shaky hands.
Take a length of non-stretch fabric, something like an arm sling, tie the two ends together, put round neck then insert hand in the loop and take several turns round wrist. This gives something to 'push' against and gain stability.
I imagine a length of cord would work, if not so comfortable on the wrist.

Thread: Rack operated tailstock ?
07/02/2020 20:40:48
Posted by Phil P on 07/02/2020 19:55:23:

For anyone wondering what the Cowells capstan rack feed tailstock looks like, this is mine.

It took a long time to find one at an affordable price, I dont think they have been made for a lot of years now. There is one on ebay right now for just a tad under £300 !!!

 

Mine is the same but in Grey. In 1973 was fortunate to purchase the 1965/1966 year ML7BT with Brook Gryphon 2speed motor and Dewhurst control gear, with the Cowells tailstock and Trileva and QCGB already installed, with many chucks+dividing head, etc from a fellow club member retiring from workshop activities.
It took some persuasion for the budget manager to approve £327 but it has earned its keep many times over.
Back on topic, I deduce the Cowells was installed between 1965/1966 and 1973

Having had a Cowells Capstan rack-feed tailstock on the ML7 for many years, along with @CornishJack, I can compare it with the usual screw-feed tailstock and say that it is much better overall - more sensitive more instinctive and quicker in operation.
With a 1.6mm drill in the tailstock chuck and a 3mm bar of stainless in the 3-jaw it is possible to 'peck' and withdraw to clear chips with just a finger and thumb on one of the capstan bars with hardly any effort, to a depth of 12mm..
Highly recommend.

./.....can't do the math, but liken it to a plastic bag tube. //The bar I am going to try has a 12mm diameter shank and a min bore diameter of 14mm. It would be great to be able to do the math t hing and figure out that if it has 120psi it becomes this rigid for example.

Neil

Neil, I like your plastic bag tube example and confess I am also unable to do the math.
Unless I have completely misunderstood your proposed bar dimensions, the min bore id of 14mm appears to be greater than the 12mm shank diameter.

snip/ Changed from Simvastatin several years ago for some reason, but can’t remember what. /snip

I can echo that, Jan2016 had a lung X-ray and liver ultrasound as prelim to starting to take Methotrexate for Psoriasis and the ultrasound revealed an Abdominal Aortic Aneurism 36mmH x 25mmW x 35mmD and was put on 75mg soluble aspirin and Simvastatin. Long story short..sudden appearance of increased frequency and urgency to urinate and inability to drive less than an hour without needing to - urgently.- or else Complained to doc and was changed to Atorvastatine when all returned to normal.
(AAA has remained same size since through several follow-ups with Vascular specialist)
