Swarf Brushes
« on: December 14, 2016, 10:23:18 AM »
I use quite a few in the shop here.  The other day I turned some horrible cast iron and pretty much contaminated every brush within reach trying to keep the machine clean...  I failed and needed to service the lathe, I was about to throw out all my brushes when I hit on an idea.  Drop them in the ultrasonic cleaner with hot water and washing up liquid.  Press and swirl the brushes a few times to open them up and let all the accumulations drop out.   Overnight the brushes on the stove ( or radiator) they are clean and good as new.

I won't leave it as long between cleaning brushes now I know this works.   The ultrasonic cleaner is a real cheap <20.00 job I have had for years and a handy little device for small items I work on.  Maybe it's time I bought a better one ?

Just get doing and make swarf, you can decide what its going to be later.   :thumbup:

Drop in a magnet at the bottom of the tank - even better

When machining cast iron, hold the nozzle of the shop vac in the line of fire and you'll collect a good 90% of the black dust if the vac is any good.

The shop vacuum is always a good idea.

Hi chaps, the workshop vacuum is indeed a good idea, there is an occupational disease called Turners Lung caused by inhaling cast iron dust, I have only ever personally known 4 people who acquired it ( in the 54 years that I was a turner) but none of them said that coughing up rust was fun. Of course in modern times one has the benefit of high pressure coolant, swarf conveyers & high powered overhead  fume extractors but not generally in your shed or man cave.

If that vac is not a "wet and dry" with the motor outside but just a regular household one make sure the bag is well filled with wood shavings and general dog hairs first to act as a pre-filter for the bag and motor cooling air. :thumbup:

Shop vac is what I use too, during and after. I have a twin-motor numatic I got off eBay for 50, does wet and dry.

Mostly, I use throw away sample pot paint brushes got em free from local paint shop. But always clean up before leaving the playpen for the day with my $50 el-cheapo vac. Sadly, after 5 years or so I can smell hot wire insulation each time I use it now, just waiting for the blue magic smoke to appear.
  Incidentally, I made a small cyclonic separator in line and it works fine. Bag in vac gets very little stuff unless I have turned plastic. That seems to float in the air stream rather well - light mass, high surface area I guess.
