This is the deal, and to be honest is about the best I could have hoped for....

£45 each + postage ( calculated @ £2.50 1st class signed for )

Lead time is 2-3 weeks

This is based on a batch of 20 being cut.

I sent you a P.M. before I saw this thread.

I think you have been quoted an excellent price on a custom tap. I don't need one... however I do want to point out to others how good this price is.

[Dan]

Put me down for one.

[Marky Tizz]

what does it do?

[Jordie]

I believe its the correct size tap for the end of the crank. where the flywheel bolt fits.

[mini7boy]

assuming that this is the tap for the flywheel and pulley bolts, I have also heard the thread referred to as a 5/8-16 UNS thread.
Is this correct?

If so, that's not a bad price, but for U.S. readers, the firm Mc Master Carr at http://www.mcmaster.com/# has a 5/8 - 16 bottoming tap for around $35-40 U.S. dollars

I have been told that this thread is the same as for the flywheel and pulley bolts.

Mini7Boy, the picture posted by Harber07 summarizes the situation extremely well (and is very funny I might add!).

Rather than re-start a lengthy discussion, see this thread which precipitated Guessworks getting these taps quoted:

Hi,

The McMaster one I believe is a UNS, you may wish to check this first......... As Whitworth is even rarer in the USA

Really is a bargain, friend who got ours said to buy it who'd have cost eighty to hundred quid.

Hi Doug(DKLawson)

before I ordered the tap that I posted in my previous comment about the 5/8-16 tap for $35-40 U.S. dollars, I checked with a Mini racing pal
who bought the tap I cited from McMaster-Carr and has been using it for years. His email to me citing this website for Mc Master-Carr
was dated 2006 !!!!

I have had one of these taps since his email and simply re-checked it today for a pricing update.
Predictably, the price is now several dollars more, but still quite reasonable at $36 which is about 25 quid or slightly less.

I cannot create a link to the specific webpage which shows the 5/8-16 UNS bottoming tap.

This page will take you to the page where you specify the 5/18 part of the tap spec.

http://www.mcmaster....ng-taps/=18yw8l

Apparently, either the UNS and Whitworth are interchangeable or they are in fact the same thread.
Either way, it matters not because McMaster-Carr simply calls it a UNS thread rather than Whitworth. It works by either name.

Whitworth are indeed rarely mentioned in the U.S. and not too many tap suppliers list Whitworth threads by that name.

So, U.S. buyers can get one for this very reasonable price.


PS - I didn't get the can of worms with my order, just the tap. Worms were $5 extra.......but only available in metric.

[/font]]Thanks for your concern, MRA. Honestly.

Please take no offense at what follows because it is not directed at yourself.

The tap I posted the link to is almost certainly a UNS thread.

Which thread has proven perfectly fine for my purposes which are merely to clean out the threads to remove old Loctite
from the threads in both ends of the crank. I have never damaged the threads in a crank, so I have only needed a gentle clean out,
not a thread restoration. Actually, I'd like to hear just how people have managed to damage these threads such that
they needed a tap to restore them. I can't imagine damaging the threads or just what it would take to damage them. It's
certainly never happened to me!

Again. No offense intended, but it sure sounds like it would take some pretty hamfisted efforts to damage a crank's threads.

I run the tap through the threads on both ends of my cranks and the tap always threads through quite nicely and achieves the desired purpose.

So I had to laugh a bit while reading the other "thread without end" in which half of England weighed in with opinions citing chapter and verse
on the subject of crank threads.

Perhaps if we were all restoring threads or installing threads into something unimaginable, I could see the reason for debate. But we DON'T.

But if you are forced to restore mangled threads, by all means use the Whitworth, if that's the correct tap.

Otherwise, I don't think it matters whether a UNS or a Whitworth tap is used. Another distinction without a difference for most of us.

So, I'll just continue to use my 5/8-16 UNS tap that costs only the equivalent of 25 quid(I probably paid about 15 quid when I bought it).

I know loads of people with similar UNS taps and they somehow manage to build road and racing Mini engines successfully.
