While out doing my weekly running I stopped by a guys place an bought a handful of odd and end stuff.

Picked up some American made reamers 3/8 to 9/16 all good an sharp
Also picked up some end mill cutters various ones an sizes all American made cutters see pics....

Also picked up a partial stick of some 2"x 2" x 5ft. Delrin so I can make some new bushings for my wife's wheel chair... Chose the Delrin over Nylon, Was told Delrin is a better choice to use.

Don't think I did to awful bad on price as the Delrin would of cost me far more I would imagine... spent a total of 45 bucks for all of it...

Could of spent less if I would of just bought the two endmill cutter's I originally went by for but its like going to HF can't go in with out coming out with other things you didn't go there for....

Yeah, I prefer machining acetal to nylon. Pure natural nylon and UHMW are both machinable but the "chips" come off in long continuous strings that can create a heck of mess. With acetal you can generally break a chip which makes cleanup a whole lot easier.

Plastics in general are pretty complicated; there are a wide variety of basic "families" and within each of those there can be many different compositions. Delrin is actually Dupont's name for its family of acetal products but it's one of those terms that has become almost generic in nature.

Most manufacturers make a lubricant filled material, sometimes referred to as Nylon MD. Because one of the first manufacturers of this material was called "Nylatron" that term has crept into general usage as a term for all lube filled materials but Nylatron uses the name in conjunction with a wide variety of plastics it produces...

Not sure what the radius size is of that rad cutter, that cutter alone is worth your $45. Looking at the size, it will likely make your mill/drill cringe though except on very light cuts.

I just picked it up for light cuts on aluminum it about 3/4"... ill have in the future maybe more use for it when I get my bigger mills here.... Or at least I think ill have possibly more use for it...

I didn't think I did to bad as I'm told the one plunge drill for hardened steel/tool steel is pretty high priced new... supposed to be able to cut taps and drill bits but not carbide
I guess the worst I can do to it is screw it up....

will this be the better material to make the bushings for the wheel chair over just nylon :confused:

Yes it will. It has real good lubricity too. Lots of folks have used it to make half nuts for their lathes.

It's the better choice unless she weighs over 4500 lb because under heavy pressure nylon distorts less, but I always think nylon needs lube.
Great score on the delrin and reamers. As far as I'm concerned You Suck.

I have both white and grayish blackish Delrin one is better to use than the other if so which one would be best... the pieces needing replacing are the bushings that allow it to fold and keeps seat in alignment when it folds

although she thinks she weighs 4500 pounds in her mind and she really believes she is fat she truly only weighs buck forty five.

For that application any plastic will do. Delrin, UHMW, nylon; you name it; there isn't enough load that you'd be able to tell the difference...
