Question when boring the inside of this pipe how do you keep the surface finish appearing transparent or clear so to speak??? I have these 6 inch pvc diameter pipe pieces to machine, they are oval a bit ,even at 89 dollars a foot .? Now i plan on using a piece of aluminumn and turning it down (the aluminumn) to fit inside the Unmachined inside 6 inch pipe diameter THEN i am going to machine the other Half of this aluminumn fixture down to the finish inside PVC Pipe Diameter diameter minus a .001 or .002 thou. Then jam the machined end of the pvc onto the other end of the fixture and bore that half ,flip part and also switch fixture to the bored diameter and bore the other side .Whew finger typing cramp. I have 2 pieces to make and they are 6.300 inches long. Thanx Guys madman

PVC PIPE EVAN thats what it is. Thanx Mike
Transparent PVC will not cut to a transparent surface. You can get fairly close with a very sharp high rake tool that has a large radius but if it needs to be completely transparent then it will have to be polished after machining.

You could try Solvent polishing after machining.

Well i got some 8 inch diameter OD and 6 inch ID DOM Pipe and bored it out to hold my PVC Pipe. Then machined (Turned the Outside) NOW i am going to drill and taop a Pile of 3/8 inch tapped holes all over the outside and use set screws to hols (squish ??) the pvc pipe ropund ??

I was hoping someone was going to be doing something with purple PVC pipe.
A truckload of the stuff is a real eyecatcher.

A friend of mine had good luck using regular household vegetable oil when drilling/machining acrylic plastic. You might give that a try. They were making experimental hydraulic test blocks and wanted to see what was going on through the plastic.

Yaeh i asked my wife and she was immediately suspicious. Her reply you know what a lousy cook you are im NOT letting you heat up a gallon of Oil on my New Stove and then going off to drink beer and end up burning the House down? I never did get back to her .(she thought i wanted to cook a turkey or some critter on top her new stove LOL) Im just gonna sneak out to that place the women go to buy food (i think its the supermarket? i never been in one) and buy a quart. thanx I hear M.E.K . also can make the surface translucent after machining. I am thinking of using a HSS freshly sharpened cutter in my 1/5 inch diameter boring bar for this Job. I need to make a steady to supoport the end of the 8 inch od pipe. Thanx Mike

MEK isn't great. Pretty mild stuff, like acetone and evaporates fast. Methylene Chloride is what we used to use. Not so much anymore since it's way more toxic and carcinogenic. Your best bet may be to polish it. Some pretty decent plastic polishes available these days at auto supply stores.
PVC isn't a good candidate for solvent polishing. Buffing with a soft compound works best.
