BA sizes

Thank you for taking the time to respond.

I have sent Bill ("br" three messages using this system and my SENT box tells me that he has NOT been able to read any of them!

I'm NOT very adept at all this computer stuff.

With best wishes and thanks again.

Sounds like you've cracked sending them MC, but Bill hasn't sussed out how to read PMs yet. Maybe Bill simply hasn't noticed the flashing - it's not obvious! I sometimes take a while to notice them. Or isn't logged in.

After logging in and seeing a message alert click on the Inbox and a list of messages should appear. Another twist, to open a message click on it's title, not on who sent it.

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,

MC Black

Looks like Br has deleted the message sent to him without reading them from what I can see As his inbox is empty but there are showing in MCB's sent box as unread.

Sorry Brian but the problem(s) appear to all be you or your equipment. As I said I can replicate the messages not showing by logging in as you and deleting them. Also if I log in as you I can open your album page without a problem. Same for the photo problem the other day where you had the album marked private not public which was stopping people being able to see the image. You have also had problems asdding images in the past under one of your other user manes

We can only do so much at this end the rest is down to the user.

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,

MC

The tables above have been most usefull

Opened up a new box of Sherwood M5btaps, today, to find that they don't want to go into a 4.2 mm hole. Why? 5.25 mm diameter although marked 5 x 0.8! So look like being incorrectly marked 1BA!

Howard

May I ask the source of this data please?

It would be useful to have a laminated copy in my shed-workshop but I don't know how to print just the table.

Very many thanks in anticipation

MC

Did you measure the pitch of the thread?

MC

Hi Howard, maybe they are 5mm taps for thread repair coils.

Regards Nick.

Hi MC, the chart is a page from Tubal Cain's Model Engineer's Handbook.

Regards Nick.

Yes of course ... it is the page which Nigel Graham 2 misquoted

... Please see Nigel’s post on page 2 of this thread ... which you have already questioned, and upon which I have already remarked.

Thank you for taking the time to respond.

I did NOT appreciate that the table came from Tubal Cain's book - I'll have to buy a copy.

With best wishes and thanks again.

MC

Very many thanks for your prompt, helpful and courteous response.

Michael -

Thank youl!
