    Ever see a switch that was put together backwards?

    This switch is in the basement of my wife's parsonage. Off is on and on is off. It's wired to interrupt just the hot from a bulb containing source power. The switch has continuity with the lever in the down position marked as off. I originally thought it might've been a case where someone...

    Welding mild steel to hard mystery plate

    Would abrasion resistant steel tell the carbide blade in my cold saw to **** off? It did cut it but it did a number on the blade.

    Welding mild steel to hard mystery plate

    Everybody loves pictures right? The original construction has the top welded on. Scars from the previous coworker welds that snapped off easily. The ledges that will get welded in to support the plate.

    Welding mild steel to hard mystery plate

    It's kind of a salvage job. We needed to move a tool with a hydraulic cylinder mounted to the bottom so the cart got a hole torched in it. I'm trying to turn that mess into a more usable cart with a removable plate to allow both uses. The strips to hold the plate in place are what I'm hoping...

    Welding mild steel to hard mystery plate

    I've got a work project that involves welding some strips of A36 to a piece of hardish something on a large metal cart. The cart was originally used to move around injecting molding tools. The top of the cart is a piece of 1/2" thick plate. I know the top is hard because when someone welded...

    Working on chuck concentricity

    I currently have the backing plate machined with a step in it that just fits inside the step on the back of the chuck. Would you suggest I hit that with a file to remove a bit or just try to play whack-a-mole with it as it sits now?

    What a perfectly GarageJournal response.

    A future project: a sleep deadman switch

    I come from a family with sleep issues. Compound on top of that a night work schedule and a wife who left me and seems to want to just live separate lives while pretending it's healthy and I find myself trying to get back to sleep a lot after the initial 4 or 5 hours. In talking with my doctor...

    Voltage callout of 200/1/60

    It is indeed a Japanese robot. In their power spec is the 200 a single hot to ground/neutral or 2 hots 180 degrees out of phase?

    Voltage callout of 200/1/60

    I noticed this voltage spec on a piece of automation equipment tonight. Am I correct in assuming that since we are looking at 200 and not 220/240 that this equipment is expected to be wired in using a wild leg of a 240V 3phase?

    Gave the shifter a trim

    I've always hated how tall most of the mtx shifters are in cars from the 2000s. It feels super high to me almost like you're driving a truck. Right after I bought my 2008 Mazda 3 I cut out 2 inches of shifter shaft and welded it back together. This week it was finally time to be brave enough to...

    Pressure washer pulses rhythmically

    Yes. The Centura carbs use a plastic emulsion tube. That was removed from the body, all parts went into a heated ultrasonic cleaner for the better part of a day before being removed, the passages chased with a 61 to 80 drill set and blown out before reassembly. The jet is built into the...

    Pressure washer pulses rhythmically

    This uses a Tecumseh Centura engine. They don't have a choke. They rely on the operator to pulse the primer bulb enough times to semi flood it and use that as a choke.

    Pressure washer pulses rhythmically

    Well, I cleaned the carburetor as a long shot. Same behavior.

    Pressure washer pulses rhythmically

    It's got an auto choke but it will give me a backfire pop every now and then at shut off so i don't think it's starving.

    Pressure washer pulses rhythmically

    I know a bit more about pressure washers than the average chap but this one is a new one on me. I picked up this Karcher washer cheap. I was told that it wouldn't build pressure. The gun had obviously froze with water in it and cracked the tube so I changed that out with a spare I have on...

    Hard jaw covers

    It became obvious that I was going to need to machine my own and these are finally done. They are made from 3/8 angle with a flycut texture to them. After machining they were case hardened for 10+ hours in Cherry Red compound so hopefully they can handle at least a moderate amount of abuse...

    Case hardening process

    I did not make new ones. I have read that the cook time increases the depth of the case. From that I am assuming that worst case I just waste some more company time and money but the jaws remain at least as hardened as they are right now. Is there something that you think could go wrong that...
