...when you just shouldn't be in the workshop...

A friend asked me to knock up a small piece out of aluminium - only 45mm long, 10mm for 10mm (drilled & tapped for M3), with the remaining length 3mm diameter, the last 10mm being screwcut for M3 again. OK, thinks I, that might be a bit of a challenge for my not-so-speedy lathe...

Well, I managed to turn a piece of scrap ally down to 10mm, drilled & tapped the end for M3 as requested. I then put the 10mm bit in my ER32 chuck.... and somehow managed to break it - the chuck, that is, not the work piece. I must have accidentally over-tightened it, because it all jammed up solid. I had to totally destroy the nut to get it out... and the threads on the chuck are damaged, so that's £30 quids worth of tool wrecked  :(

Not to be defeated, I recalled seeing some "turning" work done in a CNC mill with the toolbits clamped to the table & the work in the spindle. Thinking this seemed like quite a crafty idea, I went for it. And it worked a treat, I got the required 35mm turned down to 3mm in relatively speaking, no time flat. Cut the excess off with some snips, and went to tidy the end up a bit on the grinder, bent the bloody 3mm bit.


Aaaargh!  :bang:


Gave up. Today never happened...  ::)

Powder Keg:
Sorry you had  a bad day. It happens.

 :wave:Experience is what you get from that mistake you just made :wave:

Stilldrillin:
Ade,
Some days, and some jobs..... Just shouldn't be allowed......  :doh:

But, why do they happen so often?  ::)

Commiserations.....  :wave:

Nothing is truly dead until you have tried to repair it.

I am positive I have a spare ER32 nut here, and the threads should be able to be chased back into shape with a thread file (again, I have one here). So just put it to one side, and bring it over next time you visit, if you ever want to visit again.

Hi John,

I will do just that, thanks; although a visual inspection of the threads shows that a goodly portion of one thread is completely missing... the dings & bumps will clean out I'm sure...

I'm supposed to be installing some stuff for Cheshire East (or is it West?) Council in Crewe anytime soon; as soon as I know the date I'll let you know because then I get to visit AND charge my boss for travel  :thumbup:



Thanks for the other thoughts - I'm not disheartened (just disappointed), I only stopped because you just know that problems will snowball on that sort of day...
