Thats a thing and a half I reckon. Solid made, would be good for wet leather working to press flat wallets etc. Make a hell of a paperweight or doorstop?
Got this old thing in the garage, I presume its a book press, the plate is about A4 size and its incredibly heavy, got some cool hand painted decoration on it too, in a Art Deco style.
Im trying to think what possible modern use I can put it to.

Thanks, it is pretty cool in a industrial way, I must get the surface rust sorted and use some of that black fireplace stuff to make it a bit more sanitary, the damp garage hasn’t done it any favours since I last saw it, maybe I can use it as a nutcracker this Christmas!
Cheers..

I am waiting for Dave S's contribution. He has shown us incredible skills restoring his Porsche's engine and... inventing tools (!) for the jobs when you really need Porsche's own tools. Talking about mechanical stuff...
I was considering showing the dismantling of a Lucas starter motor for a TR6. We've been busy today dismantling one. But then i realised that it is -A- partly electrics and -B- Lucas' parts are not UK's biggest industrial triumph...

I think that most members here are aware of the marvel of mechanical engineering that is the Curta calculator, the smallest four-function mechanical calculator ever made. The history of how the Curta came to be created is as interesting as the machine itself; Curt Herzstark refined his design whilst imprisoned at Buchenwald concentration camp and probably only survived due to his technical expertise. These are, without a doubt, my favourite mechanical device.
The jewel in my collection is this very early Curta Type I, dating from February 1949. The design was still being refined at this stage and it has a few features that only exist on the earliest models such as rounded pin setting sliders, 'SYSTEM CURT HERZSTARK' inscribed on the body and an anticlockwise opening case. The Type I has eight digits for data entry, a six-digit revolution counter, and an eleven-digit result counter.
In 1954 the larger Type II was introduced, which has eleven digits for data entry, an eight-digit revolution counter, and a fifteen-digit result counter. This example dates from November 1955.
Later versions of the Type I feature rectangular setting sliders but have exactly the same internal design. I use a 1965 model in my office on a regular basis. This one is from January 1968.
And here is a later Type II, from April 1966, with the grey casing and every third rectangular setting slider knob in red. It came with a nice bespoke field case.
'Curta Corner' of my modest mechanical calculator display, featuring the four main variants.
There is an excellent exploded diagram available as a poster that illustrates the internal intricacies.

For a moment, I thought that it was James May’s voice btw
At work i get to play with - among other things - Rankine cycle steam turbines, Sterling engines, ramjets and pulsejets.
The pulsejets are very, very, very loud.....
Loving both safes. Your whisky one is really nice looking. Need one for my new office when we move soon!! (we perhaps best not mention it to the missus before the deal is done!!) The inside looks almost identical to mine as well.
Do you get that air seal thing going on when you open and close it? You have to close the door on mine slowly as you hear the air escaping.
That Big Bertha is a monster! Can't get over the thickness of the door, serious stuff. More jealousy going on. This thread is going to end up costing me a bit at a this rate!

I get the air seal thing, the little chap came from scunthorpe post office 19 years a go, i caught up with it by accident at a scrap merchants i know, the box was free but i had to pay for the keys and brass furniture. Two keys, both needed to operate the lock, Two individuals to coerce into unlocking.
The biggie was a 500 quid from ebay, i had to take it out from a high street bank at my expense,i managed this on my own, once in the street a friend with a skip firm came and collected it, it did take me a week to do and i made a 7min time lapse film.
I have an interest in old icons of daily life,
I have the clocking in clock from Liverpool train station in my hall still works, the rhythmic ticking is a lovely noise. Also two royal mail pillar boxes stand as guardians to my french doors on the patio.

Although Curta mechanical calculators are compact masterpieces considered to be the design zenith of the pre-electronic computer era, they are not exactly rare. They were manufactured from 1947 to 1970 and around 80,000 Type I and 60,000 Type II models were produced. Prices have increased recently (probably due to the exposure provided by Adam Savage on YouTube) and there are some unusual and rare variants but they all share the same internal design.
In 1960 the reputable German typewriter company Alpina (the same Alpina that later moved into automobile manufacturing but nothing to do with the innovative watch company) started to produce a high quality hand cranked miniature calculating machine with the intention of it being a rival to the well established Curta. The ambitious design led to increasing manufacturing costs and it was unable to compete; production ceased within a year and only around 4,000 calculators were built. There was a brief attempt at a revival in 1971 leading to a further 1,600 machines being produced.
Because of their relative scarcity, Alpina calculators are much sought after by collectors and museums. Like Curtas, they have generally survived very well and are usually still in full working order.
The serial number of mine is 003844 dating it to 1961 (the preceding zeros indicate the initial ambitions of the manufacturer). It is in perfect working order and complete with case, instructions and heavy metal stand for use on a desk.
Thats nice as well, has a great look to it. ^^^^^
I can see that on the corner of an office desk, row after row in a with German Gründlichkeit engineered building. With properly dressed men and women behind the desks.(VW's or Siemens' controller 'Abteiling' perhaps!?)
It's very nice and it combined the purpose-build top of the machine with the swoosh style of the pedestal. Real 50s and 60s design.

I have myself one of these, different base machine but same attachment. Makes work a lot easier and saves employing extra guys on the ground.

The door has glass plates mounted on the inside that will break if an attempt is made to drill the lock or open it by other brute force methods. These have tensioned wires attached which will release spring bolts at various points into the locking mechanism if the glass breaks, completely securing it. They are hard enough to withdraw if you can get to the rear of the door, and impossible if it is locked shut.
1959 Stuart 10H Engine. Works fine but I do intend to do a full strip down, clean and rebuild when I find the time.
Map measuring devices are a whole lot less complicated but I find them pleasantly reminiscent of the travels of my younger days and a time when things were far less automated. I like the various different coloured scales and the additional features such as the compass and magnifier.
What nice things they are. Look well made and perfect for the job.
I have some Avery Scales my wife bought and restored for me to use as my seat in the garden. Will get a picture at weekend.
Up there with the most interesting TZ-UK threads ever! Properly engineered kit and those safes, wow!

In my yoof (which seems a good way off back in the mists these days) I spent many a happy hour mooching around Tyseley rail museum and railway sidings. Great equipment and very pleasant and knowledgeable engineers with not a single bean counter or ‘elf&safety’ gherkin to be seen!
