Another stainless job

admin

Right now this is all I have for the blueprint.I ordered 6 square feet of 1/4" 304 stainless today.  A 20 foot 4" schedule? will be coming on a pick up truck in a pipe rack tomorrow morning.DavidReal world weldin.  When I grow up I want to be a tig weldor.

Reply:6 square feet of 1/4"  304 stainless.  I have no room for error, so I took my time and measured a couple of times before starting.  Rotobit.  OIl works better than PB blaster.   Drill says 475 Rpm on it.      Bits say 400 for carbon steel.  I think it should be about 1/2 that for stainless, but the bit had drilled 8 holes so far. My dad gave me this drill Press.   It kicks *** compared to the belt drive one I bought from Enco.Last edited by David R; 12-01-2011 at 07:27 PM.Real world weldin.  When I grow up I want to be a tig weldor.

Reply:dont know what your building david, but your drill press is bad ***.
Reply:The bit held out till the last hole, then I attempted to sharpen it.  I think I will just buy another one.  Stainless is a bitch to drill.   This is by far the best so far.I set the circle cutter and made a test cut on some 16 ga before cutting on the stainless.    Things came out just right.  The circles are 11 1/16 and the holes are 6 3/4" apart.Next I have to cut up the pipe and weld them together with no distortion....\Powermax 600 turned all the way up 78 psi when flowing shop air.Here was today's fun.   Real world weldin.  When I grow up I want to be a tig weldor.
Reply:Today I cut up the pipe and finished the job.I squared the saw first and took a couple practice cuts to make sure I was getting what I needed.   I don't to buy a piece of pipe.I had 2 saws running today.  This is a 6" X 1/4" aluminum disc I put under the flange to absorb the heat and help me preload the piece so it does not warp as much when I weld it,.I hand tightened each bolt then added 1/2 turn.  They are 1/2" X 13 if some one wants to figure out how much that is.  Real world weldin.  When I grow up I want to be a tig weldor.
Reply:I lined up the flanges by clamping both pieces together and filed them on both ends.  Its all I could think of.  They did not warp or sugar.   The aluminum disk was a success.And the welds.  I tried with and with out a gas lenz.   The bigger Torch and cooler I ordered came in in complete. So its still Arcmaster 185 set to full but using maybe 2/3 of the pedal.   WP20 torch 1/16 tungsten.  With or with out gas lenz, 14 to 20 cfh argon.Real world weldin.  When I grow up I want to be a tig weldor.

Reply:Nice man! Yeah 304 aint fun to drill.. Its not bad if you have a rigid machine like a millbut in a drill press I can imagine it would be hard. You do have a sweet drill press though! Not sure what kind of RPM it turns but I would go slow and make sure your pulling a chip.303 is like butter though.. hahaHTP Invertig 201Lincoln Idealarc SP250Miller 180 AC StickBy farmall:They should have held the seagull closer to the work, squeezing evenly for best deposition.

Reply:Originally Posted by zipzitI'm reading with interest the thread originated by BoostinJDM-My-Name's-Not-Jim entitled "Un-warp me please"  Was your action to add the aluminum preload & heat sink influenced by JDM's warpage issue?  (I'm not criticizing you.. I'm really thinking I'm very glad JDM posted in the first place...)Where do you guys learn this stuff?And most importantly.. thanks to all for sharing both failures and successes!   Perhaps failures is too harsh a description.. lets call that opportunities for improvement for next time.  Again, thank you David (and JDM) for posting.  Nice work!--zip

Reply:i see.  when i was doing pipe work we did what we called two holing.  you'd make sure the pipe was level, then make sure the flanges were plumb, then line a level up across the tops of two holes on one flange and make sure they were level, then do the same on the other side.  or you can buy two hole pins which fit in the bolt holes and give you a surface to rest your level on. some of them have levels built in.  handy little buggers.you can buy them at www.pipefitter.compipe can get tricky to work with and its maddening how quickly it makes you feel kinda stupid...or at least thats what ive heard, not that a stupid pipe has ever gotten the best of me....
