Is Delrin toxic? I was in the garage three different times today making collets and different tool jigs out of delrin. I notice that when I came in to warm up, my nose began running, and actually burning. I also began sneezing a little. I was just wondering if anyone else experienced these symptoms after working with this material?? I guess it time to get out my mask! Thanks.

That might only get worse. If you don't want to die, start thinking about some dust collection at the cutting sources.
 
You're getting it too hot I think.
Wear a mask all the time.
Melting Delrin is not good. It has formaldehyde. Definitely not healthy fume.

Yeah It can cook up just like a poly, just seems like It has a slightly higher heat range, but It can still melt/burn. gotta control speeds and feed rate, sharp tooling helps too. It cuts pretty smoothly though when you get a feel for It. The way It peels off, the cleaner that action, combined with the correct speed, and smooth feed action, the smoother the finish comes out. I make collets and joint caps from delrin, and the final cut is so clean they need no sanding or much of any polishing for that matter. As far as alergies, I have had none with delrin unless It was overheating. I've found that when properly cut, I have less of a reaction from It then most woods or glues.
Hope this helps. Joey's right though, if your smelling It, then that's not good, the stuff can be toxic when that takes place.

When cutting Delrin you want to use a large radius tool. The larger the radius, the smoother the cut.

Sure enough, I use a sharp round nose with a smooth profile. I can hand feed with it, and It's cuts really smoothly. I have one I grinded into a simular shape, but It comes to a sharp point, and that one does'nt work so well on delrin at all. I plunge in for profiling or facing with other styles sometimes, but when I run the lenth of the OD, that round nose really works well for Me.

How much do you value your fingers?

Why haven't you found someplace to get training on machining?
If you wanted to be a great composer, would you be unwilling
to waste all that time learning to writre music? Play the piano?

The way you are going, you are BOUND to either injure
yourself or your machine tools, or both.

Get some pills for your ADD an crawl before you dash

Dale, dont you think that is a bit harsh?
Have you made a perfect cue yet?

Actually I think mistakes are a very importaint part of learning.
It is one thing to know how to do something but quite another to know the 'why' behind it.
That is what a mistake teaches ... the 'why'.

Please dont go off on a rant about sticking your fingers into a saw or something like that just to learn what happens.
I think you are smart enough to know the point I am getting at.

If all you ever do is follow instructions from others ... sure ... you will make some very nice cues.
BUT ... if you try new things ... Different things ... Crazy things ... if you can think of new ways to try and do things, in the process you will find what works best for you ... Then you will make better cues because you will better understand not just the how but also the why.

We should all be pushing the limits of cuemaking and our skills not just grinding out the same old thing over and over.
We should never stop growing and learning new things.
Good enough should never be good enough.

I have never made a perfect cue lacking something that I think I could have done better ... the day that happens I will most likely quit cuemaking for good.

Sounds like you need better air flow in your work area.
Do you use any kind of dust collection?

Super Glue fumes get to me big time.
I need lots of fresh air flowing thru the area when I use that stuff.

fumes

I think delrin is quite safe to cut if you slow down some and cut rather than vaporize the material. Taking a course in machining may not teach you a thing about toxic chemical fumes when cutting plastics, a rather specialized area.
I think Dale went a little overboard on a rant on yah, maybe he is just concerned that some people are not being safe enough, understandable.
CA fumes are downright nasty as others have said, be careful there, you need more than an open door to keep from sucking them in. And Clear outo finishes are way worse, they can absorb into the skin with just the vaporized mist!
I suppose the best advice is to think more than once before acting on anything. I mean it is easy to cut off wood, but way harder to add it back! Not to mention fingers that may get in the way ... ouch!
Besides if you work delrin too fast you will never maintain any type of quality and accuracey. You will throw out too much material. Good luck!
 
Thanks for all of the wonderfull replies. It turns out that I have a horrible cold today. May have all been quencidental, who knows. Yes I know what you mean about Ca glue. When I make pens I use a lot of it. I tear up really bad even when whearing a respirator. Safety, I think that im very safe with most operations. I am very conscience about it and I respect all macherine, not to say that nothing could happen, I just error on the side of safety at all cost. I never reach over the chuck but in front in tead. Ect, Ect!! I have thought about going to a community college for a class in basic machinering. Tinkering around a little all ways helps though. Again thanks for the help.
 
Don't think that a respirator it the end all for protection. CA goes for moisture, like eye fluids. Same with isocynates in car coat. Good ventalation is a must. Consider a hood of some type when spraying. I have one made out of tyvek that has an elastic opening in the front for your respirator to stick thru. Keeps the crap away from my eye's, and has saved me several sets of glasses. And I have a 12inch sparkless vent fan.
Amazing how those vapors get around.
 
Ventilation is a must as others have stated...I have dust hood over the lathe that will suck in anything relatively light in weight...with any plastics you want to turn 'en slow...like 100 rpm or less...esp. with MP Ivory...if you look at that stuff wrong it starts to burn and melt...

WHAT were you thinking?

Are you running for office?
What in God's name does this hogwash have to do with my reply?

Don't you think telling someone to ignore safety issues while
operating machine tools is more than just a little bit
irresponsible of you?

before you reply, do a search on this fellows posts, then tell me
if you think he needs advice?

OK Dale.

Quote from my post ...
"Please dont go off on a rant about sticking your fingers into a saw or something like that just to learn what happens".
"I think you are smart enough to know the point I am getting at".

Did you miss this part or just ignore it?
Now everyone can see why I felt the need to type that.
It was just in case you were the type of person that will take a post apart word by word, twist it around,
then rant on and on about something that was never said or implied.

I withdraw my previous statement about thinking you are smart enough to see my point.
Asking you not to go off on a safety rant was also obviously a waste of my time.

BTW ... I was responding to what YOU said in YOUR reply to him.
Not to what HE said in HIS previous posts.
I take it you dont like that guy very much ... am I right?

Now you can fire back and question my manhood, my sexual preference, my ability to make cues,
my mental state, my mommas choice of footwear, and/or anything else that you may feel will insult me, hurt
my feelings, or inhibit my creditability here.
it is all part of the game here ... I understand.

Yes, your feet are ugly too. :D :eek:
I see them in your site and I throw up just a little.
Safety issue there Willee?:D :eek:
Don't drop a drill chuck!

He He ... I was sure someone would rise to that bait.
Seriously ... I dont like people that misquote and take things out of context just to have something to argue about.

Joey ... I'm a tellin ya.
My best cues are made in bare feet!
Something about being well grounded I think.

What is with the free jimbo thing?
 
Wilee or wontee

I'll limit my consideration to your desperate need for attention.

Although I never posted, I lurked at rec.sport.billiard
for 5 -6 years.

This is entirely typical behavior, blundering in on something you know nothing about.

I invite anyone who wants to use Google groups search
to view a few random rantings, promises to leave forever, etc
for a first hand look at a persecution complex in full bloom.

Get help, please. For us, if not for you.

Something told me you were that kind of person, Dale.
I could sense it in your attituide and manor.

Was that far enough back to see the emergence of WilleeCue as a poster there ? What a hoot that was ... thanks for the memories Dale !

<edit> OK, perhaps some relevant information ... To get answers to these kinds of questions you should ALWAYS refer to the MSDS (Material Safety Data Sheet) first. They are available for pretty much any material you might work with, and are an invaluable resource. Here is a link that has many MSDS, inlcuding Delrin (for the obvious reason that it is a Dupont product) : http://msds.dupont.com . To find an MSDS on any given product just google "MSDS Whatever" and you'll get a bunch 'o hits. I just googled "MSDS acetone" and got many sites with this MSDS. <end edit>
