Head bearing trouble

I've put the race bike back together with a new bottom *yoke* [1] and
everything now appears straight. Unfortunately no amount of
tightening the head bearings will eliminate all of the play (

The new bearings I've fitted are stock Suzuki from Crescent but it
used to have tapers in there. Would I have any more joy getting a set
of tapers from BSL or whoever? I'd have thought they were exactly the
same size so wouldn't solve anything but I'd appreciate the thoughts
of those that have a clue, unlike me.

The outer races fitted into the headstock quite easily but a mate
reckons they should have been an *extremely* tight fit. Is he right?

[1] For the benefit of Eddie )=

 

He might well be - if they fitted that easily, that's probably where the
play is.

I know you said the new ones are stock Suzuki, but are they the same
size as the old bearings?

Lovely.

 

A very worrying but accurate thought as the guy at Crescent said
exactly the same thing (

Assuming that is the case, any idea where I can get it checked/fixed?

 

Digital Verniers? How does that work then?

 

As cool as digital Vernier calipers are, what's wrong with the good
old-fashioned calipers where you had to know what a Vernier scale was to
use them?

 

Heh.

As I'm sure you probably know, they're Vernier calipers, but they also
have a digital readout for the numpties that don't know what a Vernier
scale is.

 

Nuffink.
But these young whippersnappers today...

I think you've answered your own question.

 

Only 9/10? Where did I go wrong?

 

Pah. Bloody kids today. Don't they teach them anything at school?

 

Of course, what you *really* want is a micrometer.

 

They're nice, but it depends what you're measuring, innit?

AFAIK, micrometers don't go as large as Vernier calipers, and they can't
be used for measuring internal dimensions.

[Waits for evidence of 6' micrometer with internal measurement adaptor...]

I've seen some bloody big ones in my time... wiv extensions... Ooerr...

You can get internal micrometers, no problem.

OK, I sit corrected.

But a standard Vernier caliper will do internal, external and depth - to
make the same measurements with a micrometer you'd need three
micrometers, wouldn't you?

For accuracy, yes. A Vernier caliper is fine for rough work to the
nearest mil or so, but I wouldn't believe it any finer than that.
The digital Verniers might be more accurate, but I've a feeling it's
simply putting icing on a pig.
