    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.

    The issue with an eccentric bushing in this...

    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.

    1- Form it from sheet
    2- Oblong a tube in a press, build a channel of the appropriate size and force the tube into it in a square cross section. It may buckle weirdly

    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.

    I'm sorry but this isn't accurate.

    For a typical transformer used to convert one voltage to another based on the ratio of windings (this excludes resonant, shunted, and current transformers)...

    The motor is rated to spin about 5000 rpm at 130V, so that's about 38.5 RPM per volt. At 12 volts that gives 460 RPM. 24 Volts gives double that. If I were doing this I would use a rectifier and...

    It's weird to me that such a small brake has such a big motor. What is the tonnage on it? Mine is 70 ton and the travel and bending speed are plenty fast.

    I'm 90% sure the ADX-10 would be fine but...

    I run a 6.5hp press brake, very similar to what you have (only larger), from a phase converter built from a 10hp motor.

    A rotary phase converter is what you need. Whether you build one or buy one...

    The nameplate amperage and efficiency correspond to 4.5 HP if single phase or 7.75 HP if three phase.

    The next step is to remove the cover on the motor electrical box. If it is single phase there...

    On our Hyster (don't remember the model, but pictures on google look identical) there is a mechanical linkage between the brake pedal and transmission that puts the transmission into neutral once you...

    I second the treadmill motor.

    You can get them for $50 surplus for fairly high power capacity. A cheap speed controller and rectifier will cost $20.

    What may work very well for you is that...

    Sort of. You'll need to determine how much offset from center the punch could be worst case. From there you can determine the load on each edge of the bushing from the resulting torque.

    Though...

    I have a similar (but larger) brake. If it's like mine the motor circuit and back gauge and ram height controller are on totally separate circuits. My particular brake is an Adira but to my knowledge...

    Some sort of easily operated, lockable disconnect is nice.

    At my old job they snapped a fitting off of an air compressor tank with a forklift and I was able to operate the disconnect from 15 feet...

    Some help with a dead blow hammer on the other side took care of it.

    I've used that style of bushing and I like them much better, having two screws for removal. Also, you can see how they work...

    Alright, well I feel stupid. I thought hub tapered the opposite way and tried to use the two tightening holes to release it.

    6010 and 7018 primarily, in flat and vertical up.

    Most of my messing with inductors for arc stability was several years ago making a low powered arc engraver for labeling my tools.

    I haven't tested it with welders, but drawing an arc from transformers I found little benefit by rectifying the output, at any of the voltages I tested.

    I have found that I can draw much longer...

    It's worth noting that I don't think diodes on their own will make any improvement, and may just worsen arc blow with no other changes. I think the inductors are the most important part (though...
