Pretty much the last remaining worthwhile radio/electronics rally at this end of the country is on
next Sun 22nd, Stockwood Park, near Luton:

I'm planning to go. It's my favourite.

I wonder if it's worth taking the camp stove and some bacon for a diy
picnic? Perhaps it will just attract the rain ..

Someone's written a glowing report of the Newbury rally on the wiki,
but I've never been to that one.

Adam Page generously forked out for near gears for the milling machine and I fitted them this afternoon. One of the old gears
had lost one tooth and the other was missing two,retty much as expected.

Fitting them is far from simple and took all afternoon so please do not change between high and low gear while the motor is
running as I don't want to have to repeat the exercise any time soon.

Yes - Newbury's usually quite good on the occasions I've been.
The only regularly decent rallies in the last few years have been the outoor bootsale types.
The reason for this is that the low venue cost means stall fees are very cheap, so they attract a
much higher proportion of people clearing out their attics than traders trying to make a profit.

A combination of high stall fees and ebay have decimated the rally scene in recent years - the
older amongst us may have happy memories of three packed-full halls at Pickett's lock.....

Given that we now have the pillar drill - how about fixing/discouraging any shifting - as most stuff which need the other speed can be done with the pilar dril ?

Not a good idea, using the correct cutting speed and feed rate for the material is important. Steel would generally be fine
in the lower gear but aluminium needs a much faster speed - 10,000 RPM or more isn't unusual but even in high gear the
mill can only manage about 2,000 RPM.

The sort of people who ignore the warning about changing speed while running are just as likely to ignore a rule that says
always use low gear, and the mill has a two speed gearbox for a good reason!

The new spindle gears are steel instead of the original nylon ones so should last a bit longer, but the intermediate gear is
only available in plastic so is just as fragile as before. It is rather easier to replace though, considerably less hammering is
required.

Please could you start a new thread by creating a new message? Replying
to an existing post and changing the subject line causes some mailers to
file this message under "Electronics Junk Sale". Anyone who's not
intersted in an electronics junk sale might well delete the thread and
miss this warning.

Thanks very much for carrying out the maintenance on the mill.

Regards,
Mike.

Hi,
I wouldn't mind going.Haven't been to a electronic junk sale for ages!
Last one was in Milton Keynes or Luton from memory.
Is there a chance of a seat in a car from London?Can chip in for fuel.

Is the handle ok on the table? Seemed a bit wonky to me last night.
Didn't actually use the machine tho.

I'm not quite sure which handle you mean. There is a problem though -
the two halves of the head (sorry, don't know their proper names)
aren't fixed together totally rigidly, so the spindle can move around
quite a bit. I can't see any external screws to tighten it
unfortunately...

Also I broke the remaining bandsaw blade. :-( I vote we buy that circular saw...

That sounds like the proper names to me :-)

The screws are accessed from behind, the head needs to be removed from
the column to do this. I have been a little less gentle in tightening them this time,
so hopefully it will now stay fixed.
