I'm trying to get a hold of a tool that will undo grub screws
securing the front panel knobs on my venerable BC221, can anyone suggest
where I can get a hold of one, a modern equivalent and/or something that
can be modified to do the job ??
Although all BC221s were provided with the tool (stored in a
clip beside the spare valves) I've never seen one and can only guess
that it must be something like a very small Phillips screwdriver head
but with a parallel rather than tapered tip. It must also be less than
3/32" dia 'cos I've just tried to make one by hand out of 3/32" dia
steel rod and that was too big, don't think my eyesight is up to hand
filing the cruciform tip in any smaller dia rod, hence a request for
help !!
My BC221 is still furkling along after 63+ years (& only c/s -
There, I've said it !!) out of calibration) but I think I should at
least try & smarten up the case with a good clean and a bit of fresh
paint. Who knows, it's probably got more chance of making the century
than I have.
Thanks

You need Bristol wrenches or Bristol keys or whatever Bristol calls them.
They come in 4 or 6 point form. The 6 point ones look very much like Torx
head screws. You need the 4 point type. I got mine from McMaster Carr:

mcmaster.com

I don't know if Bristol wrenches are easily available in the UK. McMaster's
website seems to be down right now, but I have to figure they do
international orders.

Dick, you got a lot of helpful feedback on your question - yet no response
from you.

Don't you think a simple "thank you" would be in order?

I'm glad to see that others feel the same way I do about that. I
often respond to questions, and end up with no idea if my response was
helpful or not. "Thank yous" are nice, but feedback even without a
thank-you would also be welcome, just to know that we're not talking
into the wind. Also, an "I solved the problem (thus-and-such way)" is
helpful: we then know we don't have to write any more, and maybe we
learn another way to solve such a problem, or place to get such parts.
Sometimes the discussion is worthwhile even without the OP's
response, but I'd always like to see _something_ back from the OP.

Welcome to bash me unmercifully if I fail to follow up like that on
any question I post!

Cheers,
Tom

Yes, my fault & I should have got back to thank everyone for their input
to my BC221 query sooner than this. I've now got a set of small Bristol
wrenches on order from the US and I'll post an up date once they arrive
& I've had a chance to try & remove the grub screws (carefully).

Once again, thanks for all the suggestions & loan offers.
