Has anyone read of, used, or know of any laser hand-held measuring tools for benchmarking [a client's] water jet / laser cut piece parts, stampings, formed parts and fabricated subassemblies?
I am looking for a digital or laser [or other] hand-held technology to replace my mechanical rules and...

Many Marman clamps are used with sealing beads that are formed onto the tubes they connect. But SOME use slip-on, beads that sleeve over the ubes. I cannot seem to dig up any guidelines fir weld size or quality for these slip-on Marman beads. Anybody have a suggestion on this...
Can anyone share whether or not the branch pipes welded into / onto a larger ID pipe header extend down into that header?
I know that for COMPRESSIBLE flow, this is done with 60-degree angle cuts in the branch pipes extending inside the header; but is that done for INCOMPRESSIBLE flow too?
My...
I can't remember...
...For purposes of calculating horsepower consumed across parallel pipe paths, when flow is equally distributed across parallel paths of the same size, are the pressure drops across the individual runs additive
I mean...do you find HP based on...
HP = [Qtotal * (SUM...
I can't believe this - I was just reading something on how to size terminals for more than one gage wire - and now that I need it, I can't locate it for the life of me!
Can anyone remind me how to determine the proper [solderless] terminal size for coupling more than one gage wire in a single...
Can anyone suggest or does anyone have postive feedback for online courses in process validation methods and procedures?
I'm looking for online training similar to redvector.com (no IPV courses, though).

If any of you are die casting pros and / or know of a thorough die casting design fundamentals handbook, please would you share the title, author and publisher and ISBN?
Thank you
Can anyone recommend a digital library of hose fittings / hydraulic fittings?
At a previous place of employment, we had fittings in our system, but honestly, I can't recall how we got them.

I've lost my PDF copies of some of my ASTM standards during relocation. NOW I'm learning how priceless they were!
Can any of you remind me of the 1B/2B/3B etc surface [quality] finishes for sheet steel fabrications? I've spent more time looking online than Thor Heyerdahl took crossing the...
Can anyone advise how to factor in time of contact / exposure between two surfaces when estimating BTU rating for an AC unit to chill glue very fast?
I want to pass a glued bag between cooling blocks to chill the [hot fluid] glue from 245-250 deg. F down to 220 deg F. Here's the rub: my design...
Can anyone remind me the equation or steer me to an immediate resource for the Polar Moment of Inertia of extruded retangular tubes for figuring total shear loading at the Neutral Axis for a rectangular hollow tube with a torsional load?
Cheers!

Anybody know of a better way - other than straightness - to specify against excessive "twist" when welding to a long, narrow flat?
I know straightness will govern "bowing along the full length, but does it also govern "twist" along an axis tangent to the long axis?

I wanna toss my hat in for American getting serious again about space!
American's gotten a pretty black eye from industry shifts away from home, and now with chine being soooo good at aircraft manufacturing thanks to the traitorous folks at Boeing, seems to me there's one last area where - at...
Can anyone steer me toward a resource offering suggested concentricity tolerances for rotating elements at - say - various speeds?

I have a [non-fitness equipment related] industrial application where I think I can exploit using one of the manually released [to lower] / spring raised air cylinders that are seen in commercial grade fitness machines. these are the ones that are independent of any air source other than the...
I have a question for any of you Precor or Nautilus fitness machine designers out there:
