need a little help making something out of delrin......

[Don Ferrette]

Looking to see if anyone might have some delrin laying around that could spin me out a piece out on the lathe. I need a delrin ring made with a .498" i.d. 1.00" o.d. and .250" thick. I need to press this over top of a bearing to act as a spacer on my router. Can't see buying a whole stick of delrin just for this so I'm hoping someone has some scraps kicking around and can make this up for me.

Hey Don,

Let me check in the shop. I think I have a piece to make that for you. I could bring it to Charleston if you could wait till then?

if Blaise dosen't, let me know I have some black 1/4" delrin I could make this for you

Would Teflon work for you Don?

Might be a tad too soft?

I have 3/4, 7/8,1,1 1/2 and 2 inch in stock. can do it if no one else can. might want to use more press than .002 though. I would double that

Ok cool, so to go over the .500" o.d. bearing you'd go looser than .002" on the fit?

 

[glenng]

If you double the press fit Don you would be @ .496" bore.

Yes, I would go tighter, might need a couple different ones with different size I.D.'s to try. Delrin has a high expansion rate. Warm it up and press it on.

what they said

 

[glenng]

Don't heat it in the wife's oven Don, You might get banned from her kitchen forever

.

 

[Duck899]

Warm it with a heat gun or hair dryer, I'll cut a few tomorrow just to see how they work out and measure how much they expand.

 

[Don Ferrette]

This is what I love about this site, lots of great people willing to lend a hand even on the most trivial of projects.

 

[glenng]

Is there a specific reason for not using Alum. on this project Don?

Yes it needs to run against unprotected wood so I would prefer delrin.

 

[Blaise Recca]

I found some stock but it is only 3/4 inch out side dia.
