Building up base, machining/tapping weld metal?

Getting closer...

I need to track down a 1/4" NPT tap. I have a 1/8" and something seems to hit me that I bought a 1/4" NPT a couple years ago so I need to dig a bit in my stuff boxes to see if I can find it.

There is plenty of meat on either side of the side port for threading. Again, it will not be subject to much pressure at all.

I am not sure how much more clean up I'll do on the shape of the manifold - it doesnt matter. All that matters is the placement of the holes (I'll flush it pretty good to degrease and get the chips out from inside etc).

I found a tap the right size. I thought I bought one for a project about 3-4 years ago and ended up not using it. So I dug for it a bit and I found it. The tap worked OK - I didn't chip any teeth. It was a slow boat to China to get through carefully but it worked - with oil every so often and lots of backing out to clear chips. I think it will hold up for round 2 for the bigger manifold next, not sure when I'll get to it but I'm getting there slowly.







These are all the local pieces in the set up. The hose will be shortened to what I need for the unit. The supply hose connects to the union (that is the larger female thread you see on the stack coming off the pancake regulator).

Not sure what you are making
But this stuff works great on tapered threads....
I never use teflon tape anymore.

Just don't use it on pool equipment/chlorine or you will have more leaks than you can shake a stick at. One case where tape is best.

Good point.

you got me... That IS the one place I use teflon tape.

although I have been known to get pissed off at a niggling leak and just PVC glue the damn thing...
