pressure? industrial or residential? live steam or lemonade ?

My recollection tis the ASHRAE handbooks have practical information about plenum sizing and much much more.

With all them gears I'd expect lubrication churning etc might start to matter.

I've had a few experiences similar to MintJulep in Post 5. Most recently when looking for a chart of tap drills for varying % thread when tapping an 8-32 hole in a nasty material. AI was all hung up on thread engagement and could not be convinced otherwise. Attached is one man's opinion of AI

If you are providing more than two diameters of thread engagement the aluminum thread "strength" may not be a problem. This is related to post 3 CWG1's second paragraph.

Like this ??

If the Ø10 mm shaft was centerless ground it could easily have a three lobed profile that checking with a micrometer can't detect. "However did anything ever get made before (E) was invented?" ASME's Y14.5 Rule 1 is the default. "Envelope Rule" or "perfect form at MMC It might have appeared as...

I believe there are some surface finish requirements amongst the Groovy specifications. I'm thinking a dynamic seal really needs lubrication. Is the actuator pressurized by air or oil? What is the actuator maximum pressure ?

get Blodgett's book(s). Many tips here, including back-step welding. https://www.lincolnelectric.com/en/welding-and-cutting-resource-center/welding-how-tos/weld-distortion If the results aren't quite good enough, get out the oxy-acetylene torch...

rotate for fabrication? or it will it rotate in service ?

So the vibration sensors are mounted to the bearing housings ? Is there just one sensor on each bearing housing? Sounds like they are hard mounted and not readily re-positioned for vertical or horizontal. Are the vibration measurements filtered 1X rotational, or "unfiltered" ?

Among the many other hitherto unidentified details things the holes in the shims are going to need some careful detailing lest their square edges become locking devices. https://m.media-amazon.com/images/I/71anrnKKStL._AC_SX522_.jpg...

Maybe has an NL Option kit ? whatever that is ? CONNECTION OF DC-1000 WITH NL OPTION KIT TO LAF-3 (Obsolete) from page 20 on the Operator's manual here - https://files-us-prod.cms.commerce.dynamics.com/cms/api/tflzsjpjnb/binary/MA2z4B

" the seal was cut at an angle making a "thread" like feature that helps work the oil through the sealing lip and spitting it back into the bellhousing " What direction does the crankshaft rotate relative to the seal "thread" ? Is country of origin molded on the seal? Does that match what the...

I think fuel gas fittings are often LH thread.
