Thread: beryllium copper compression spring needed

Remembering back to my aircraft days the MoD was very cautious and careful with regard to the use and handling of BeCu. So much so those that came into contact with it had the details added to their personal records in case of future claims for industrial related illness.

Same for things like Cadmium and Magnesium Thorium.

Personally I wouldn't have anything to do with it unless you can be sure you can maintain an adequate barrier between it and all points of entry on yourself.

Many years ago I was told that a cut from Copper/Beryllium would sooner or later lead to a heart attack. Needless to say we handled the stuff carefully.

Sounds like a Borrowdale needle, used in surgery, dissection, microscopy and various prodding, cutting and poking jobs.

Never heard one called that before, I've found one reference to the name on Google.

I used to sell a lot of these 50 odd years ago, seem to be referred to as Dissecting needles nowadays. Daveb

Add a retractable scalpel to your list, good for cutting, picking, scraping and other things.

Yes, but then it would be eleven, I marginally use a needle more than a scalpel. Strictly it's a dissecting needle too

Friend had an XK150 looked like a later version of the XK120, nothing like the D Type.

I had an E Type, I think the best looking car ever. Not the best handling though.

Thread: Couple of things at Lidl

Boys toys at Lidl.

I bought a furniture mover at Lidl for £9.95, I think the castors would cost more on their own. My wife looked very disapproving and asked what I wanted a skateboard for. I explained what it was, she told me not to play with it with my friend as we'd both finish up with broken hips. I wondered which one of us she thinks is the bad influence, we're both over 70.

I bought my saw from APTC, There was a note saying that EEC rules did not allow tables for vertical operation so this item was no longer supplied. There is not much to fit the table to, it fits to the end of the blade guide with 2 screws. I made a table 150mm square X 3mm, used it once, haven't seen it for ages.

You have not mentioned, 'Sinclair' calculators. They came on the market in the UK also with a little FM radio which you made up from a kit, if it did not work you sent it in and it came back working. It had a little bulb type earphone.

I still have 2 Sinclair calculators, one a Scientific calculator. Very useful in the early days. Of course Clive Sinclair is famous for the C5 trike car ?

Clive

I bought one of the early Sinclair scientific calculators, came with a pack of cards to program the thing. Tedious!

Surplus motors for the Sinclair electric car (which actually looked like a childs plastic trike) provided motive power for a whole generation of model locomotives. Why didn't Sinclair just make the model locomotives to begin with?

I still have a Sinclair black box digital multimeter, tiny display but worked OK.

I could be wrong but I believe Clive Sinclair invented the mutiplexer for the digital display which made pocket calculators possible.

Thread: Lathe chuck
02/01/2018 20:04:10

Most 4 jaw independent chuck backplates are smaller than the body diameter. With 3 jaw chucks, the backplate is (usually) the same size as the diameter. Check the specs of the chuck you intend to buy, will tell you what size you need.

I believe Chronos stock suitable backplates.

I'm sure there were plans for a 'Napoleon' with field carriage and limber in one of the Home Shop Machinist Project books.

It sounds like a neon indicator, they do this if there is some leakage current.

Does anyone have instructions for use of the Bridgeport Cherrying attachment please.

George, the bearings on my MK1 feedbox were not on the feedscrew, they were on a sleeve which joined the feedscrew to the feedscrew extension.

Definitely the mill! I fitted a 2 way to my mill, PCD, calculator and many other functions, it was very good indeed but I regretted not going for the 3 ways.

Welcome Danny. My first car was a 1949 side-valve Ford E493A Prefect coupe utility bought in 1972 for AU$120. These were unique to Australia i believe, with a locally built style-side rear grafted to the front half of a standard saloon body. Was a great little car, but needed more work to keep it going than i was able to commit so I sold it about 20 years ago. Mechanically pretty indestructible, but the timber-framed body was only held together by the paint. Geoff in Brisbane Australia.

Our Morris Minor 'Woodies' have the same problem, the wood parts are still available but it's a big job!
