Thread: Is there an alloy that looks like copper but isnít?
19/06/2022 06:42:14

Berillium copper ??

If it is, be very careful of the swarf, don't cut yourself, don't get little shards prick you, don't inhale hot vapours from turnings (I was told).

Thread: Fiber optic cable
14/06/2022 09:51:36

Nick, similar problem in 1976. We could not get a mini computer to RJE to a remote IBM site using modems. BT sent various technicians without success. One hot summers day another tech arrived, in shorts, sandals and long dreadlocked hair. (Some hope we thought) within a few minutes, he got his old and cracked screen AVO out of his bag, then proceeded to cut the earth wire from the modem and Bingo, the RJE link and modem connected! Our factory earth was reading +40 volts and we were an electronic equipment manufacturer !!

Don't judge a person by their looks !

Tooth pitch is also important. Some companies will cut a belt down to the required width.

Thread: Fiber optic cable
12/06/2022 17:49:47

just had fiber optic cable installed. Its incredible how it works. The fibre is 0.16mm diameter (near enough 0.006". Light as we know travels in straight lines, so how many times must it bounce off the walls of the fibre before it reaches its destination?

Thread: Silver Solder Storage
12/06/2022 17:44:26

Handy storage for sticks of silver solder. Cut some plastic rigid tube (Electrical conduit etc). Glue a cork in one end of the tube and and shape a removable cork for the other end. Affix the suppliers label to the tube showing temperature range etc. Have a tube for each different type.

Thread: The evocative sounds of releasing train air brakes of old....

Oh yes, the smell left behind when someone "pulled the chain" whilst in the station - It was actually a foot pedal if I remember correctly.

Woking station where they built the facade on the wrong side !

Are you restoring it for a museum ?

If you are waiting for wrought iron - you may have to wait a very long time ! Mild steel will most probably be supplied.

Thread: Shed floor

If you must use the chest of drawers,

1/ Bolt the lathe down to the table top, do not over tighten as you WILL twist the bed of the ML7.

2/ Screw the chest of drawers to the wall of the shed.

3/ Do everything else others have suggested in due course - but have a bit of fun with the lathe in the meantime.

When I was first married, my Southbend lathe came with me to a small semi with internal garage. The lathe was supported on a couple of 4 x 2 cantilevered bearers high enough for the front of the Alegro to be driven underneath. I carried out several pieces of charged for jobs for a machine tool company. I don't know if I will be castigated for supporting a lathe like that, of for owning an Alegro !

Thread: The Correct Way To Sharpen Drill Bits Using A Picador Drill Sharpening Jig With Custom Base

And Ps: I was taught "Never grind on the side of a grinding wheel" Where did that go out of the window ??

Serial number / model type stamped on the bed just about underneath the tailstock face nearest the operator (Front face ?)

Thread: How to identify solder on an old boiler
29/05/2022 06:16:01

Lead solder is soft and you could scrape a little off with a pen knife. Silver solder is harder, if you cleaned the joint with some wire wool, it would look a very pale gold colour.

The Stuart ST 501 is a low pressure boiler and even lead solder would be acceptable although if starting afresh lead free these days..

Thread: Injectors
27/05/2022 18:30:57

Update, 5/32 steam feed pipe, 3/16 OD delivery and cold feed via tin can / 3/16 pipe with cold water. The new check valve with a 5.5mm (7/32) ball still dribbles, so it was back to the check valve with the 3/16 ball (changed from stainless to a Viton ball)

The number 2 injector works fine approx 1/2 pint of cold water in a minute with steam feed at 60 psi.

The next trial will be using warm 60 deg C water - the side tanks on SPEEDY warm up in spite of 2 layers of insulation between tank and boiler.

After that it will be "plumbed in" to the side tanks again.

Has anyone got experience of getting injectors to work with "hot" water ?

Notice the style of the caravans and the "Social distancing". The attached was my 1937 Ruby CCE 954 in about 1967 (First year of compulsory MOT) and me as a young driver. Petrol 4/3 per gallon !!

Thread: Issue 249 Arduino Controller Indexer

Probably doesn't help, but I run my NEMA 23 off of a 36volt 5 amp PSU.

Thread: Any idea what these are for?
21/05/2022 15:54:45

Lathe tools ?? No apparent rake angles on top, side or front so I think they have another purpose.

Thread: Drone advice needed, please
13/05/2022 11:54:32

What constitutes to be an aircraft? Are there minimum weights, size etc.

Eg: Is a paper dart an aircraft ? A chuck glider, again a 20p chuck glider sold on the beach as opposed to a competition glider which could be seriously large and heavy.

Thread: Tyres
13/05/2022 11:46:37

John MC, start of thread "Recommended tyre pressure 32psi, measured pressure (3 different gauges) 45psi"

I suppose all 3 gauges could read high by the same amount.

Simple dead weight pressure test rig. Known weight on a piston of known area. I wonder how often the tyre gauges are checked at the tyre centre. Normal inflation kit is generally abused.
