Are you already beyond that point? I suggest...

    Added mass to a Hydraulic cylinder

    I'm curious about the purpose of adding weight to end(s) of hydraulic cylinder. https://www.directindustry.com/prod/bell-srl/product-17502-1175045.html Maybe make it self retracting or self extending, if the shaft is vertical? That's all I've come up with so far.

    tig welding tubing, fitting face perpendicular to tubing

    The sliding surfaces of clutch components ( also brake rotors and even brake drums) can suffer severe localized heating and frictional wear. https://www.v6z24.com/attachments/89-3400-z24-034-jpg.36543/ The late, great J. O. Almen wrote a wonderful article for Metal Progress in 1943 entitled...

    Bolt Torque and Bolt preload query

    "Never torque, use elongation" I wonder what r6155 would do if confronted with a flat tire and needs to install the spare tire. https://tech.arp-bolts.com/instructions/134-6003.pdf angle torque is pretty common on rod, main and head bolts on modern cars.

    Carb. Jetting using an A/F gage

    The Mikuni carburetor tuning manual from the 1970s got right to the point. Selection of the main jet. First ,do the following on a flat road. (1) Select the largest main jet which affords the maximum revolutions per minute (the maximum speed).

    Standards on filling holes with weld

    Use aluminum "pins" ? Then after the edges are welded, finish either with autogenous welding the ends of the pin(s) and holes or use pins slightly shorter than the assembly thickness to permit real "plug welds." Even with pins installed I think the halves of the welded assembly will likely...

    You Can’t Buy That Diesel Truck

    installation vs seating torque

    "GE spec's installation torque has no mention of preload/axial load at all, the protrusion is what defines the "installed" state for the max installation torque." I suggest proceeding carefully. I'd interpret protrusion as the number of screw/bolt threads visible beyond the nut. "Producing a...

    Strut tower bar preload: tension or compression?

    By inspection I always wondered what arched tower braces, attached with offset thin plate brackets could really offer. In comparison, the 1960s Shelby Mustang braces to the firewall looked to me to provide a 10X stiffer load path...
