    There is a simple valving arrangement that applies full pressure to both sides of the cylinder at once to rapidly extend it. I would configure two synchronized cylinders to pull an upper shear blade...

    I don't know anything specific about that DRO, but character LCDs are all pretty much plug and play. Just get one with an LED backlight and a resistor.

    I have reversed a single phase motor (starts and runs on the same capacitor) by replacing the capacitor with an equal reactance inductor. The motor ran hotter but that was largely from the fan it was...

    Looking at the way the threads end at the bolt does suggest that the blank was formed with stepped radii. I was under the wrong impression that all rolled bolts have a reduced diameter between the...

    I'm looking at the unthreaded portion of the fastener. It matches the OD of the threads on all of the bolts I've seen from Fastenal and Tractor Supply, along with various online sources.

    That's...

    Could you not just use any industrial panel mount timer?

    Have you considered using some sort of plastic?

    Sounds like it could solve all of your problems if the application can tolerate it.

    I keep hearing that yet every bolt I order or buy from anywhere is always cut. Are rolled threads only available in super high volumes or something?

    Fortunate. We're a small 3 man show. Usually only get about 20 to 30 pounds of bolts per week.

    A dumb way to check for supply line noise is to put a low value capacitor in series with a speaker across the line. Listen for beeps, woops, kshshs, or screes.

    Did you check if there is a metric washer that would fit your bolt tighter?

    For example:
    12mm on 1/2"
    5/16" on 8mm
    6mm on 1/4"
    14mm on 9/16"
    9mm on 3/8"
    7/16" on 11mm

    Also worth considering what the counterweight is sitting on. If it's a fairly small area compared to the size of the tank it may just rip up through the tank.

    The stories about Fastenal are kind of surprising to me. The store near me sells common sizes and grades of bolts for about the same price as Tractor Supply, and they sell to anyone.

    Oh, yeah, we use riv nuts occasionally in similar situations. I hate them solely because we don't have a pneumatic tool.

    If you want to go that route I would suggest self clinching hardware such as PEM nuts. They are much easier to install, lower profile, and possibly cheaper. You can also get studs and standoffs and...

    The base of our press brake was full of what we though was asphalt. Turns out it was some oil absorbing material to stop hydraulic fluid from getting on the floor.

    Eccentric cams and bushings are pretty common for adjustment, but they need some method to adjust them easily and retain them in the adjusted position.

    If your shop is bad about keeping rolls of wire clean you can get debris clogging the bushings where the wire enters and exits the feed rollers. This is common on our aluminum push pull welder.

    I would personally place a solid plug with a good interference fit then bore it out like you did before but this time in the right place.
