Handmade stage base

I created this aluminum base today, making use of some scrap element from the shop scrap box. It is not completed but, since I have to cut it for the needed length and attach the bracket for micrometer head.
I am also going to make some holes there to be capable to attach it to a tripod with common 1/4" screw. In addition, there must be some holes or slots to lessen weight and bulk.

Slot Loevestein (1621)
Castle Loevestein (Slot Loevestein in Dutch) is a medieval castle built by the knight Dirc Loef van Horne (therefore "Loef’s stein" ((stone)) property) in between 1357 and 1397.
Till the Second World War Loevestein Castle was element of the Nieuwe Hollandse Waterlinie, the primary Dutch defense line that was primarily based on flooding an location of land south and east of the western provinces. At present the castle is utilised as a medieval museum and function centre.
History
Aerial view of Loevestein Castle.
It was built in a strategic place in the middle of the Netherlands, where the Maas and Waal rivers come together (just west of current day villages Poederoijen and Brakel, in the municipality of Zaltbommel, in Gelderland). At very first it was a basic square brick constructing, used to charge toll from trading vessels employing the rivers. In the 16th century (about 1575, orders provided by William the Silent) it was expanded to a bigger fortress surrounded by earthen fortifications with some stone bastions on the northern side, two moats, an arsenal, and housing for a commander and soldiers.
It changed hands twice amongst the Northern Dutch and the Spanish (December 9, 1570 it was taken by the Geuzen, ten days later Spanish once more, and from June 25, 1572 Dutch till this day), the warring parties of the day. The castle quickly (from 1619) became a prison for political prisoners. A single popular inmate was the eminent lawyer, poet and politician Hugo de Groot (Hugo Grotius) typically presented as the "father of contemporary international law", who was serving a controversially imposed life sentence from 1619.[1] In 1621 Hugo de Groot managed to pull off a daring escape in a book chest. The idea for this escape came from his wife Maria van Reigersberg (also living in the castle).[two] He subsequently became the Swedish Ambassador to France for ten years. One more higher profile inmate was the English Vice-Admiral George Ayscue.

via the slot
A couple of nice slot milling images I discovered:

I took a big chunk of aluminum and bored a hole via for the spindle, which fits the Atlas lathe chuck. (I had the spindle sitting about from several I cut when I was thinking about developing my own mill.) The two holes at the leading of the block are the pinch bolts that act as spindle brakes the index plate at the back is engaged with a swingarm and plunger. The swingarm is internally bored and fitted with a spring and bearing ball to act as a detent for the plunger.
50 Pence coin 1994 – 50th anniversary of D-Day – Normandy Landings
Image by ell brown
Coin souvenir’s that had been in the back of a drawer. Believed I would share them.
I think that this 50p coin from 1994 was the the 50th annivesary of the D-Day landings. I had two of them.
The British decimal fifty pence (50p) coin – frequently pronounced "fifty pee" – was issued on 14 October 1969 in the run-up to decimalisation to replace the ten shilling note. Regardless of the coin’s novel shape, there was initial confusion amongst some members of the public, with the coin becoming mistaken for both the old half crown and the new ten pence piece.
The coin is minted from a cupronickel alloy of 75% copper and 25% nickel. Amongst 1969 and 1997 the coin weighed 13.50 grams and had a diameter of 30. millimetres. In 1997 the coin was lowered in size to weigh eight.00 grams with a diameter of 27.three millimetres. Apart from the reduction in size the style remained essentially the exact same (though the original is no longer legal tender).
The coin is not circular but is an equilaterally curved heptagon to aid identification. The sides are not straight but are curved so that the centre of curvature is the opposite apex of the coin. In other words, whilst the coin is of a shape which doesn’t have a fixed radius about any point, it does have a fixed diameter as a minimum dimension across the face of the coin. This makes it possible for the coin to be much more easily utilised and verified as legal tender automatically in vending machines and slot machines for instance and also to roll freely (see also curve of continual width). The exact same shape, although of a smaller diameter, was also later used for the twenty pence piece.
