Greensands,

Open up a DOS Shell by typing "cmd" (without the " symbols) in the search window then press enter.. The Dos pop up window will open. Typing "Help " followed by any command name, will display format of the command and the switches which can be used.

One useful switch that is not listed is the > character followed by a file name. This will divert the screen output into the named file, a very useful feature

Gordon

Below is an example from Windows 10, I added the last line to show the piping command:-

C:\Users\gordo>help dir
Displays a list of files and subdirectories in a directory.

DIR [drive:][path][filename] [/A[[:]attributes]] [/B] [/C] [/D] [/L] [/N]
[/O[[:]sortorder]] [/P] [/Q] [/R] [/S] [/T[[:]timefield]] [/W] [/X] [/4]

[drive:][path][filename]
Specifies drive, directory, and/or files to list.

/A Displays files with specified attributes.
attributes D Directories R Read-only files
H Hidden files A Files ready for archiving
S System files I Not content indexed files
L Reparse Points O Offline files
- Prefix meaning not
/B Uses bare format (no heading information or summary).
/C Display the thousand separator in file sizes. This is the
default. Use /-C to disable display of separator.
/D Same as wide but files are list sorted by column.
/L Uses lowercase.
/N New long list format where filenames are on the far right.
/O List by files in sorted order.
sortorder N By name (alphabetic) S By size (smallest first)
E By extension (alphabetic) D By date/time (oldest first)
G Group directories first - Prefix to reverse order
/P Pauses after each screenful of information.
/Q Display the owner of the file.
/R Display alternate data streams of the file.
/S Displays files in specified directory and all subdirectories.
/T Controls which time field displayed or used for sorting
timefield C Creation
A Last Access
W Last Written
/W Uses wide list format.
/X This displays the short names generated for non-8dot3 file
names. The format is that of /N with the short name inserted
before the long name. If no short name is present, blanks are
displayed in its place.
/4 Displays four-digit years

Switches may be preset in the DIRCMD environment variable. Override
preset switches by prefixing any switch with - (hyphen)--for example, /-W.

C:\Users\gordo>help dir >help.txt

Colin,

Your motor rating plate looks as if it has been sanded down, has a previous owner repainted your Bridgeport? I have a single phase, non-Varispeed Adcock and Shipley Bridgeport. The motor rating plate is painted, with bare metal only in places where details have been stamped. In addition, the label on the electrical cabinet also identifies the Voltage, phase and maximum current..

The picture of the connections which you show is the connection to the top of the motor. If the motor is 3 phase and configurable, the connections are likely to be in the box on the front of the motor, where the cable from the electrical cabinet terminates. On my machine, this only houses the Forward, Off, Reverse switch, is this the case on your machine?

Nigel,

I have bought memory modules from Crucial.com several times. A Google search will take you to their website, click on the flag then select UK. Scroll down to the bottom and click on "Find my Updates". This will download a scanner. Running the scanner will identify suitable memory modules and a solid state disk. You can buy whatever you wish. My 8 Gb module cost £49 and a 1 Tb SSD another £119. I bought the SSD to cure a long standing issue with the original hard disk. The SSD has transformed my machine, cold boot up up in seconds and no more lock ups while the hard disk load goes to 100% for ages.

Do you really need a new monitor? If you were happy with your TC display, I would expect SE to display in the same way. I frequently run SE on my laptop screen. The second monitor is nice to have, especially when you start assembling models but not essential.

It would seem that I may not have needed update to windows 10 Pro. However my laptop is much improved and it probably cost less than the cost TC and its training pack which I bought, only to find that I could not master TC.

Nigel,

Ignoring Windows 10S, which I know nothing about, there are three versions of Windows 10; Home Edition, Professional Edition and Enterprise Edition. I successfully used Solid Edge C. E. 2021 on an eight year old Windows 10 Home Edition (64 bit) laptop with 8 GB RAM,

When I tried installing Solid Edge C, E, 2022, I found that this would only install on Windows 10 Professional Edition or Enterprise Edition, After I updated my laptop to Win 10 Professional Edition, Solid Edge C, E, 2022 successfully installed. The only issue I have is that the laptops graphics card cannot give full resolution on my plug and play 4K monitor. My next laptop will be a higher specification machine.

It may be worth viewing the Siemens website below to see their system requirements.

https://solidedge.siemens,com/en/resources/system-requirements/

This implies that a maintenance pack may be required to run Solid Edge C. E.2022 on Windows 11

The HH method is to fit the two buttons to the angle plate, each offset slightly by a washer. The top of the buttons are then milled to provide a base location for the bottom of the part to milled. This location is parallel the plane of the milling cutter. The part is then clamped to the angle plate, located against the buttons, milled on the top face, turned top to bottom and the new top face is milled. This produces two parallel faces.

Michael,

The hacksaw blade as such is simply the source of a thin flat piece of steel. which is shaped to to give the required cone angle in the finished part.. The cutting edge is along the corner between the top (or bottom) and side surfaces The illustrated reamer may be just a half cone angle which would be easier to produce.

This is a means of producing a reamer without needing to remove half the material from a machined cone to produce a cutting edge, and without hardening the resultant part, both of which can cause problems, From the text of the article, one was produced in about two minutes, so a considerable time saving compared to the traditional method.

Tony,

An interesting thread.

A Google search for pressure vacuum gauge brings up brings up quite a few sources, hopefully something matching your requirements will be available.

In my version of the SDS6 manual, there's an ambiguous reference to the 3 axis display in the Sleep function heading.

On my 2 axis display, pressing the HA button puts the display to sleep, while the unit remains switched on and continues to calculate x and y axis positions. Pressing HA again turns on the display.

I think that the section heading may be intended to say that the sleep function is not available on the 3 axis display but cannot confirm if this is so.

Gordon

John,

I'm not familiar with the Camlock, my 254 Plus has the BS25442 Spindle which has the chuck mounting boss on the end. Looking at the parts diagram, I think that to replace the seal (23) which is behind your cover (86) you would have to remove/dismantle the complete spindle assembly. However finding a seal may not be possible as the lathe was discontinued many years ago.

You could try contacting RDG / Myford, they may have either spares from their takeover of the Beeston Myford stores, or be able to advise if it is a common seal with any other model. It may also be worth contacting Home and Workshop Machinery as their Model Engineer adverts used to mention a stock of spares from Beeston.

With regard to faceplate size, the Myford (Nottingham) Accessories Catalogue lists 254 mm Faceplates for the 254 R and 254 S lathes

When I bought my 254 plus in 2010, it did not have a 4 jaw chuck. Researching the BS4442 spindle of my lathe, I found that a D1-3 backplate could be used if the camlock pins were replaced by suitable studs. Myford ( Nottingham ) sold these studs, part number 12220/1, I do not know if these are stocked by the new Myford.

The studs shown have the an M10 x 1 mm thread for the backplate and a 3/8 Whitworth thread for the spindle nuts. The major diameter of the camlock pin removed was 9.925 mm. Measurement of the stud diameters are shown below.

Backplate       Collar             Spindle

9.722 mm     9.975 mm      9.945 mm

If the studs are no longer available I would try cutting down M10 x 1 mm bolts or threaded rod. These and matching nuts are available on the internet.

You need to supply more information about the machine and type of work before people can give an opinion. Some information such as,:-

1) Make, age and type of milling machine, horizontal or vertical. 

2) Conditions of machine. Do you know anyone to give an independent inspection and opinion?

3) Single or 3 phase. Do you have 3 phase available.

4) Type of tooling and is it included.

I hope this helps, it could be a bargain, or a liability.

Michael,

When a heavy load passes over a grid or a cover, bending occurs about the neutral axis. In the case of a grid, the underside of the bars is in tension, for a cover, the tensile load is in the underside of the webs. In both cases, the SG iron's superior tensile strength leads to another of its superior properties, improved fatigue strength. Without this, fatigue failure would eventually occur.

Jason was quicker typing than me.

Hi,

I have purchased an automatic boring and facing head. Unfortunately, the storage box has been "butchered" by a previous owner. One of the removable shelves is missing and a support for the boring head shank has been removed. To stop various items rolling around, I would like to make a replacement shelf and support.  I know that using Oak is not not recommended, what timber, available in the UK would members recommend me to use?

Thanks for any advise offered,

GordonH

Arckivio,

Google d1-3 flange dimensions, they are very similar. My Myford has a BS4224 fitting, 3 mounting studs. It takes D1-3 chucks with the camlock fittings replaced by threaded studs. I bought these years ago from the old Myford in Nottingham.

Karl,

Do you have a manual for your lathe? If so, page 15 onwards lists the range of Imperial and metric threads which you can create by fitting different changewheels driving the screw cutting leadscrew.  You do not need a conversion kit, just a few changewheels and possibly a stud to fit an additional changewheel.  Parts are available from Myford or other sources.

If you do not have a manual, pm me your email address and I can send you a copy of the relevant pages tomorrow.

I use tailstock tap or die holders for almost all of my threading.

If you need the fan to get a decent flame and without it you suspect incomplete combustion, I'd suspect you may have insufficient air supply to the burner, or insufficient chimney area.

My insurance company (NFU Mutual) would only cover an outbuilding to a maximum of £10,000, but would happily cover engineering equipment over that value in my garage which is integral to the house.
