My lathe is contaminated

[doubleboost]

I made a start on some paterns for a couple of trunk guides for a marine engine i am building
(Rob Wilson has a lot to answer for) i am using strait grained mdf on his recomendation
(i dont like wood but i must admit you can take heavy cuts 

Will it ever be the same 

[Dean W]

Yuk!  That'll never cut metal again.

[Rob.Wilson]

  you listened  to me

I hope you have a shop vac. If not, do not blow it away. If you do, your whole shop will be permanently contaminated...

I hate to come over all "Health and Safety", but some say that MDF dust from machining can cause respiratory problems if too much is inhaled. I don't know if that's true, or if it really relates to prolonged exposure in manufacturing situations, but it might be worth wearing a face mask of some sort.

But who am I to talk  ? One of my tasks for Tuesday is to bag up some old asbestos/cement roofing sheets and take them to the local tip. That's if the weather is as forecast (heavy rain all day), which will help to keep the dust down.

That is a very valid point they reckon mdf will be the next asbestos
I must admit i have worked in the motor trade and smoked for the last 40 years, but i did wear a dust mask whilst machining this

OMG! You need to clean that off NOW! That stuff is like ACID! Next thing you know it will multiply and MDF trees will start to grow. They will eat the iron for nutrients!!

Got the lathe cleaned up 

But it has spread on to the mill 


The end result was worth the mess

Always wondered where MDF was from....seems obvious now.

[John Hill]

But it has spread on to the mill

Nah, that is probably new growth!

[Artie]

Yeah, Johns right, thats definately new growth... thats how it spreads... from host to host...check inside your garbage can.. you'll find loads in there.... seems to be an ideal breeding ground for the spores.....

Mate these plugs look great...almost ala Rob Wilson style..... I look at his plugs and go "WOW...I would'nt put sand on those..."

Seriously, when I first saw the post I went "oh.....bugger", this stuff wont be the next asbestos, it already IS. I believe the US has very stringent requirement for its handling and I just dont use it if I can help it. I believe its mostly the resins they use that are the issue... but I dont care its just nasty stuff.

My plugs are straight grain pine or any soft wood that I can find....

loking great, cant wait for a result from th esand...

[Powder Keg]

I really like to use poplar to make my patterns out of. Nice straight grain and there isn't much difference between the hard and soft grains.

[Brass_Machine]

Artie has it right, those are some nice looking plugs. What are they going to be?

***Never mind, I found your other post! HERE

I saw that first pic and thought, "Well, here's another nice mess you've gotten me into."           

Nice clean up, too!

Hi Guys,
If memory serves the fear (paranoia) of MDF is not the dust but the Formaldehyde vapour that can take a time to disperse after manufacture. The dust is after all only wood fibre and therefore "organic", so it must be good for you!
