    Nut plate Counterbores

    Also, don't forget that the Nutplate is installed on a sheet of some thickness, so I think you could also include the sheet that it is attached to in your "counterbore" depth stack-up.

    1950's GLB Spec

    No idea really, but could it have been meant to read- "NLGA", Nation Lumber Grading Assoc?

    Tolerance for pipe to nozzle mating

    Consider your eccentric reducer carefully- installed the way you show, it may allow an air pocket to form in your suction pipe.

    Can I butt weld 1 1/8 .035 4130 tubing or do I need a "fishmouth" sleeve?

    I would suggest looking at a re-design of this tube assembly if you desire to install a bearing on the tube- I don't think installing it and butt-welding the tube back together is a good idea. At some point that bearing may need to be replaced, even if it isn't damaged from welding heat and...

    Electrical conduit pipe

    Thank you Anna, now that I think of it, I have seen plastic conduit similar to that starting to show up in some of the supply houses around here.

    Electrical conduit pipe

    Redsnake, do you have a link to an example of "VP" tubing? I'm curious, never heard of it; We mostly use EMT in the states.

    Very wide tolerances on non-critical features

    Tolerances that loose are almost an insult to the shop people, I would just leave it blank and let the general tolerances note cover it. Or maybe print it in Braille for the supposedly blind machinists... Probably get drill bits thrown at me when I walked thru the shop...

    Trico Oiler VS sight glass on bearing housings for oil check

    Also consider the newer Trico Watchdog oilers with integrated sight glass. They are a sealed unit unlike the older traditional Trico oilers. This means they can be used in a semi-sealed bearing housing without spilling oil all over. I don't really see the need for more than this.

    How to decide the size of a receiver tank?

    My vote would be to add another compressor along with larger delivery lines. If you've already had your existing compressor go down due to a burned up motor, you know what happens without any air for your production machines- people standing around and no product going out the door. A second...

    Sump/sewage pump size for run-off ground water discharge questions.

    A couple of other obvious things to check- make sure all the existing pipes are clear of debris, a partially clogged discharge pipe could be why your pump is unable to keep up with the extreme flow scenario. Hopefully this was already checked, just making sure. Check the pipe from the driveway...

    High pressure water closed loop process with gas generation and priming

    Maybe you are looking in the wrong direction; what about piping loads? Could heat-soaking or something cause unusually high piping loads to be transferred into the pumps? Just thinking out loud here.

    Pump motor high current

    Why was the pump/motor overhauled? From the data that you are giving us, it worked better before the "overhaul". I would guess that either something was re-assembled in the incorrect position, or with incorrect clearances, which is causing physical rubbing during operation, or internal...
