The woman that has been holding me hostage for 45 years (you know, the one who's father very cleverly hired a ventriloquist to say "I do" at the registry office) has asked for a "swing" for her 66th birthday.

I thought she said "I want to "swing" " but no, it is actually a garden swing that she wants.

All the ones I showed her "online" she pulled faces at and said no-way! So I have had to undertake the building of a swing.

The main timbers are 4" x 4" 10 foot fenceposts and so it should last for some considerable while. I started it this afternoon and I have built one side of it and the top cross-beam.

Here it is propped up on a spare baulk of timber on the patio. I have to complete the "A" frame with a cross-brace so I can flip it over to do the other side/end.

The "Really difficult bit" will be transporting it down to the bottom of the garden where she wants it to be installed under the big twisted willow tree.

Today, on the 82nd anniversary of Kristallnacht, "The Night of Broken Glass," when more than 1,400 Jewish synagogues were destroyed, thousands of businesses smashed and looted, and hundreds were killed by paramilitaries and civilians across Nazi Germany, in what is widely considered the beginning of the Holocaust...

We will be lighting a candle tonight, remind us to drown out antisemitism, racism, intolerance, and hatred...

Never means never
 
Hans Koenigsmann, Vice President of Build and Flight Reliability at SpaceX later said that sensors detected an unusual pressure rise in gas generators on two Merlin engines. “When we looked at the data, we saw that two of the engines attempted to start early, and the auto abort prevented that. By doing that, it prevented a possible hard start that could have been damaging to the engine hardware.”

The Merlin engine is powered by RP-1 kerosene and liquid oxygen, one of the oldest-used mixtures in the aerospace industry. To ignite the engine, a green-colored compound known as TEA-TEB (triethylaluminium-triethylborane) is used. TEA-TEB is a pyrophoric mixture, meaning it combusts in exposure to air.

Koenigsmann added, “You need to introduce these liquids in the right order. If you do this in the wrong order, or if you happen to throw in the liquid oxygen and the RP-1 and the igniter fluid, then what would happen is… we call it a hard start. A hard start would rattle the engine in most cases but could cause damage. So in general, you don’t want that. You want a good startup.”

“If we see the pressure rise too early, then we know the liquid is in there, and it shouldn’t be there,” he said. “And software in the engine controller then stops the whole process.”

Oops

Teams were able to analyze the engines’ startup behavior, and additional inspections found a blockage in a narrow line leading to a relief valve on the gas generator.

The vent port, which is just one-sixteenth of an inch wide, was obstructed by hardened masking lacquer. Koenigsmann described it as similar to red nail polish.

The gas generator on each Merlin engine drives a turbopump feeding RP-1 kerosene and liquid oxygen to the main combustion chamber.

Engineers at SpaceX’s McGregor test site also demonstrated that the engines performed normally after removing the blockage from the vent valve. Koenigsmann said that the issue was “very subtle,” but could’ve had some negative impact on the engine operation.


That’s a very original name for an engine! I wonder how long it took the ‘let’s name the engines with a totally unique name’ committee to come up with Merlin? Gosh that’s a great name for an engine. Strange no one ever thought of that one before o_O

and relax :oops:
