silicone cone

[monark88]

I have something in mind that requires I use a silicone, or something with similar "slickness" and somewhat mildly flexible, cone shape.

It has to be 2 1/2" to 3" in height x approx 1 1/2"od x 1" id, at top and 7/8"od x 5/8" id, at the bottom of cone. All dimensions are approx. Some leeway is OK.

Anyone know where I could get such a thing? I've done an internet search, but was unsuccessful.

Anyone have an idea where I might find something similar?

Hi Russ
Would Delrin work for your application? Has a low friction coefficient and machines beautifully.

are you needing it for a dead or live center?

sound like something that Rubber Chucky might make, or buy one of his chuckys and modify it to your use.

Would the silicone mold rubber fit the bill? You can get this at craft stores AKA mold making kits.

Yes.

I am not mold making savy. Do you think I could make a mold and then pour silicone in the mold, of course after the mold cured? Or would the pour adhere to the silicone mold?

Neither. I had a wild idea to make something to reset the wine cork, in wood.

Russ; I remember that AAW Journal (or Wood Turning Design?) had an article where a person made a vacuum chuck gasket using silicone caulk and cornstarch. He mentioned that it could be dyed as well.

I think if you lube the mold with oil or Vaseline it will not stick to another layer. I think this is how you do two part molds.

thanks Randy
but not quite what I'm looking for. I think I have presented myself with a project that will take too long for me.

Thanks Gary. I do have the original silicone part. I think I might be able to make a silicone mold from that. Actually I was hoping someone here made molds.
