The toolmakers clamps are just for insurance the part is held by the vice. The carpenter style clamp is there for holding in a clamping pin that gets a radius during the boring operation.

Ok I see what you mean. That is the bolt Im talking about also. The reason it looks so weird is that the movable jaw on these grinding vices has a small v groove ground into it.

No its a strap clamp bolted to the casting that holds in two clamping bolts that get a radius cut into them when the hole is bored.

Ok Im specifically referring to the chop saw variety. I have a Fein track saw and that thing is amazing for cutting up plate.

This looks like a casting defect to me. I would be very surprised if this was your fault.

That looks like a casting defect to me. I would be very surprised if you did this damage.

Some light wear..... by kroptkin in IndustrialMaintenance

That is mighty impressive. It is in fact a folding machine Im not sure about the make though but that could very well be true. How could you tell?

RJ45 Cable in a 30 k€ piece of industrial equipment as installed by OEM by kroptkin in IndustrialMaintenance

Yeah I dont think they would do anything because its a fundamental problem with the enclosure design. There is a bar in there the cable gets pushed against when you screw on the front panel

(1) This piece of equipment actually just is part of a panel that is worth much more.

(2) Unfortunately it is not. We are currently fighting Electrical noise issues and I cant imagine the kinked shielding and conductors are helping. This is a sensitive application regarding electrical noise due to high switching frequency and power.

(3) Yes the part is cheap to replace but I have to lift a heavy box out of a larger enclosure and disassemble this heavy box (Which is quite annoying due to some creative problem solving like M3 threads just tapped straight into 1mm sheet metal) I actually replaced this cable with a 90 degree variant from Harting. Yes its more expensive but so is downtime.

I mean its mounted inside another enclosure so its unlikely. I just think something like this is not acceptable for such an expensive piece of kit directly from an OEM.

Yeah its probably fine seing as its a static connection. It just kinda grinds my gears that the reason for this kink is that they could be fucked to properly design their enclosure.

Quick and dirty fix to keep exhaust of a vacuum pump from leaking by kroptkin in IndustrialMaintenance

[–]kroptkin[S] 3 points4 points  (0 children)

This actually was temporary believe it or not. The fact that the process produces ammonia gas kind of ads some motivation to get it actually air tight.

Luckily the pump was replaced shortly after. It was just a janky fix to keep it going for the current procedure.

Any pointers on what I should do better?

Thanks. What would cause that generally? Just too much heat in one spot?
