GonneVille Posted November 25, 2008 Report Share Posted November 25, 2008 I need to have some Delren plastic machined, and the info says it can be done using the same tools as steel without risk of fouling. Is there anyone out there who can do some lathe-turning for me? All I need is to have a round plug slightly smaller than 4" made, and ring lands cut into the sides.

NTHER91 Posted November 25, 2008 Report Share Posted November 25, 2008 i have one but im no help cuz i cant use it so this response is BS Quote Link to comment Share on other sites More sharing options...
KillJoy Posted November 25, 2008 Report Share Posted November 25, 2008 i have one but im no help cuz i cant use it so this response is BS I have a mini-lathe. I might be able to get this done. Do you already have the Delrin? KillJoy Quote Link to comment Share on other sites More sharing options...
GonneVille Posted November 25, 2008 Author Report Share Posted November 25, 2008 I have a mini-lathe. I might be able to get this done. Do you already have the Delrin? KillJoy Yes I do. I need check some measurements, though. Basically, I want to build a piston valve. It needs to fit inside a 4" PVC pipe, with just enough room to slide freely. One ring land should give me all the seal I need. Quote Link to comment Share on other sites More sharing options...

How long will it end up being, and how long is you stock? KillJoy Quote Link to comment Share on other sites More sharing options...

KillJoy Well, that might be the hangup. What I have is a 1" thick block, about 1'x8". How difficult would that be to get into lathe-able shape? Or is it something I'd have to buy round stock for?

HAOLE Posted November 25, 2008 Report Share Posted November 25, 2008 I have access to a full machine shop (lathes, mills, press, surface grinder etc). Let me know if you need anything. Quote Link to comment Share on other sites More sharing options...
Lustalbert Posted November 26, 2008 Report Share Posted November 26, 2008 You could prototype it with wood to verify the single ring design. So your stock peice is 8"x8"x1"? I have a smaller metal lathe and a mill with a rotary table. PM me if intrested. Quote Link to comment Share on other sites More sharing options...
GonneVille Posted November 26, 2008 Author Report Share Posted November 26, 2008 Thanks, Rick and Andrew. I'm gonna see what KillJoy can do. If he doesn't have the right tools, I'll get in contact with you guys. Mike, yeah, you guessed it. I want to build a 4" to 2" piston valve. The whole thing is, a piston valve can open faster than anything but a diaphragm valve, which operates on the same principle, but buy custom building it, I can eliminate some of the convolutions inside an industrial valve and get a higher flow rate.
