Thread: June Issue |
14/05/2021 19:37:39 |
I have a Print and Digital subscription to Model Engineers' Workshop I received an email message on my computer telling me that I could read the June issue so I opened "Pocket Mags" on my iPad to do so. Pocket Magazines, on my iPad, will only allow me to read May 2021 - Issue 303. I can't see any way of closing that and opening Issue 304. What am I doing wrong, please? I hope that you, your colleagues and your family are, and will remain, safe and well. MC

Thread: BA sizes |

This problem with OFF LIST messages that "br" is experiencing confirm my long held belief that computers work by Witchcraft! I have now received an email message from "br" and replied by email. It's always sad when somebody gives up a long established hobby. I hope that you and your families are, and will remain, safe and well. Yours very sincerely,

But rather than receive a notification that there's a message, it would be far simpler if the message just arrived in my INBOX and to which I could reply by email. Your view may differ! With best wishes and thanks again. MC
I could not agree with you more - a nice simple solution bill Dear Bill I'm sending this in the open forum. I was taught to be cautious at University so I have created a unique email address that you can contact me with. It's [email protected] I received hundreds of spam messages so sending you one for you to contact me is a risk I'm prepared to take! I look forward to hearing from you and thank you, in anticipation, for your interest. I hope that you and your family are, and will remain, safe and well. Yours very sincerely,

Does everybody know how to find messages sent to them? It would be a lot easier if they just arrived in one's email client! ...
Though they look similar Private Messages aren't emails. The word 'Private' reveals their main advantage. Only members can exchange PMs, and only the Forum administrator and addressees can read them. PMs are much more contained than emails, which use a store and forward mechanism to route stuff across the many different servers and interconnected networks than comprise the internet. Store and forward means multiple copies are taken, and - even worse - the global nature of email means spam! On the plus side, email is more capable than PM because it allows attachments and other bells and whistles. The software used by this forum isn't particularly friendly when it comes to PMs in that the facility is behind a menu (Inbox tab, top left) and not everyone realises it exists. When a PM is received the items ringed in red below flash, and the message ringed in blue appears in the Friends pane.
From the Inbox a tick box sends an email notification whenever a PM is received. Dave
Thank you for taking the time to respond. I have sent Bill ("br" I'm NOT very adept at all this computer stuff. With best wishes and thanks again. MC

Does everybody know how to find messages sent to them? It would be a lot easier if they just arrived in one's email client! You can set the system up to send you an e-mail notification of messages, just go to settings on the green bar and then select my account . Second item down is a box to tick for notification. You also get the flashing icons on the website when you have a message waiting. Thank you But rather than receive a notification that there's a message, it would be far simpler if the message just arrived in my INBOX and to which I could reply by email. Your view may differ!

If you click on the "Inbox" link (on the green bar at the top of the page), you'll be taken to a page where all you incoming messages are displayed. However, you will also see there a link for "Sent Box". If you click on that, you will be able to see whatever you have sent. Rob Thank you for taking the time to respond. It's unintuitive to have to look for SENT messages in the INBOX - but I fund them. Does everybody know how to find messages sent to them?

Dear Bill I have tried sending another message using the "Message Member" link I don't understand what I've done incorrectly. I have spent a long time trying to find a link to the messages that I've sent - but there's only a tab marked INBOX. With best wishes and thanks again. MC

If you have a six-jaw chuck, you can use it to press tube around small nuts to form your own spinners. Use bored-out and annealed tool steel and they can be hardened and tempered for long life. (Not my tip, I read it in one of the mags years ago - note that six jaw chucks can usually grip very small diameters). Neil Thank you for taking the time to respond -- but I don't have a six jaw chuck. I have never seen them advertised for the Taig/Peatol Lathe. MC |

Cromwell Tools offer open end BA spanners, so maybe they offer nut spinners also? They do, but they're a bit expensive. Links to https://www.cromwell.co.uk/shop/hand-tools/nut-spinners/7-pce-ba-nut-spinner-set/p/KEN5569520K Rob Zoro sell the same nut spinners at around £2.50 each - see: **LINK** But they are out of stock on the 4BA size - which is what started me on this topic. I live in hope that somebody will be offering a 4BA nut spinner at a comparable on Ebay. In the meantime, I can use a 1/4" screwdriver bit handle having started the nut on the thread so the magnet doesn't take control! Very many thanks for all comments MC

I have resorted to Tubal Cain's Model Engineers' Handbook (3rd Edition). Going through the table of BA hexagon sizes (page 4.13), it's clear that 4BA is about the only size at 0.498" that is close to a regular size in both inches and millimetres. Many other subscribers have indicated that 4BA is 1/4 inch AF. I'm sorry to appear dense but exactly which dimension of an 4BA nut is 0.498", please? MC

Hi MC, no problem. Delivery charges for under £17.50 is £4.99 ex- VAT which is found in their T&C's 6. Orders paragraph. Regards Nick. Very many thanks for your prompt, helpful and courteous response. In my view, Companies should make the postage charge for small orders visible next to where it advertises "Free delivery for orders over..." This exemplifies what I wrote about something fitting in a "Large Letter" for less than a pound! With best wishes and thanks again. MC |

If you do get a 1/4" screwdriver handle don't forget to remove the magnet otherwise nuts will get pulled in and unlikely to engage on short studs.
Thank you for taking the time to respond. That sounds like the voice of experience! Any suggestions as to how to remove the magnet, please? |

The stress of doing this has convinced me to be VERY cautious about buying anything by Mail Order from anywhere, especially from overseas.
That seems a bit overly cautious perhaps. Millions of people worldwide buy millions of things online every day with relatively few problems. If you buy from one of the reputable UK suppliers that advertise on this site or in ME magazine etc, you should be pretty safe. Most have eBay shops too. And if you have an unsatisfactory purchase eBay will organise a refund etc, as will Paypal. Pretty much no risk these days. Postage costs within UK surely are not that much are they? I get most of my ME supplies from the UK and I live in Australia. Postage costs are not prohibitive. And if you are prepared to take a punt on some of the cheap as chips stuff on Aliexpress etc, postage from our highly esteemed trading partners in the Orient is mostly free. Just seems like it should not be that hard to get a 1/4" nut driver, or a full set of BA drivers for that matter. I was taught to be cautious at University ! Postage costs within the UK are NOT unreasonable but the "P+P" charges made by some sellers ARE, in my view, way too high. I don't think it's fair to charge £5.00 postage for something that will fit in a "Large Letter" and could be sent for less than a pound. And I don't want something that I've bought for a pound or two to be delivered by somebody in a White Van. I have bought things from the far east in the past but only very cheap items. Sometimes, I've abandoned the project by the time the item has arrived. I am currently thinking of buying some electric candles for another (theatrical) project but there's insufficient information as to whether it will prove suitable so, even though the postage will be less than petrol, I'm thinking of visiting the seller's premises to actually try the various candles in the chamberstick. Since I've NOT used my car for 14 months, it will do it good to have a run of 100 miles. Since I have a Blue Badge, I am rarely required to pay to park. I appreciate that many readers will disagree with my views but please do NOT attempt to persuade me to change them. I hope that you and your families are, and will remain, safe and well. MC

Hi MC, some at CPC but the postage for a single item may put you off. Regards Nick. P.S. you get free delivery for orders for £17.50 or more, currently, excluding VAT Edited By Nicholas Farr on 12/05/2021 07:16:21 Thank you for taking the time to write. I tried to find the cost of delivery for orders under £17.50 but failed! I was thinking of a "screwdriver shape" nut spinner. I do not think that the extra torque provided by a T-shaped handle would be needed for 4BA nuts. With best wishes and thanks again. MC

I'm looking out for a 1/4 screwdriver bit handle at a reasonable price since it's been shown that 4BA is almost exactly 1/4" AF. I tried looking for 1/4" Nut spinners - but I think it would be easier to buy Hen's Teeth With best wishes and thanks again. MC

Very many thanks to everybody for their comments I will manage with a 1/4" Screwdriver Bit handle for the time being. The cost of postage often makes buying things from Ebay uneconomic - apart from NOT knowing if any descriptions are fair and accurate. I recently bought a book from an overseas bookseller - although he described it as "Acceptable" many of the pages had been scribbled on and I told him that a fair description would be "Poor". The stress of doing this has convinced me to be VERY cautious about buying anything by Mail Order from anywhere, especially from overseas. |

I have tried using a 1/4" screwdriver bit handle but the 4BA nuts do NOT seem to be a consistent size. Some fit but others do not, even though they all have a 4BA thread. […] . If some of the hexagons are over-size, then it seems you are ‘on a hiding to nothing’ ... You need to find whatever wrongly sized socket happens to fit them. MichaelG. . Edit: __ maybe useful link Thank you for taking the time to post. Actually the nuts are smaller than the 1/4 driver. The BA-bolts data is interesting - on both of the sites for which links are provided, the figures are in inches - but I was told years ago that BA is actually defined in Metric. When I find useful data, I like to print it, laminate and keep in workshop. Sadly both the tables are NOT in an easily printable format. With best wishes and thanks again. MC

I'm a bit surprised you could not find BA nut spinners or similar. Have you tried Chronos or ModelFixings? They may have them. I have tried both; Chronos does NOT sell nut drivers and Model Fixings do NOT have BA sizes in their range - only metric. But Very many thanks for the suggestion. |
