So if I read 100v from 120 to my disconnected wires, then the disconnected wires must have a 20v induced voltage from adjacent wiring? I will try connecting the two and see if the reading changes. Thank you for your input.

Hello all, I've decided to add some recessed ceiling lighting to my living room. Since my living room light switch is currently wired to energize an outlet (house built in the 60s) I will be adding the new lights to the 20A breaker circuit that only has a single front porch light on it. My front...

The only reason I ask is that when the machine is in home position the fixture is at a 45. If the pins were to come out in this position (which they have years ago, before the plates were installed, and the fixture fell on the floor), it would be left to the stopper plates to keep the fixture...

EngineerTex, the load on these plates would be static as there is very movement of the fixture when constrained. I will look up the bolt data and calculate. Jboggs & jgKRI, the shoulder bolt is in fact used as a hinge point for the plate to swing out of the way without completely removing it...

Tmoose, yes promptly plummeting to its demise.

We have some equipment that just came in with removable fixtures. The fixtures are locked in place by pins the majority of the time. During a jig change, the pins are released and the fixture rolls out. My question is about the plates that are mounted on the fixture carrier. There are two 12mm...

In fact it is SeasonLee. It would make sense as we are a Japanese owned company. Thank you all for sharing your vast knowledge. This is a great forum.

Additionally, has anyone ever seen this nomenclature? I'm referring to the two symbols that immediately precede the HOLEhttps://files.engineering.com/getfile.aspx?folder=cc31628b-2ee1-4fa4-858a-f692919a8fb2&file=Symbol.JPG

I've attached the datum feature on the other end. So datum A would be the axis of the cylinder correct? The line that passes through both of the nuts is a dimension line shown in this picture on the right (from end face of cylinder to centerline of nuts). I think I have enough info now to...

Also, how do I know what drafting standard it is? I do not know and the print doesn't specify. I assume that would be a question for our design group.

This is a drawing for a new project we have recently acquired. The drawings were provided by our design group. Our fixtures were, from what I understand, designed and fabricated by an integrator. I am a manufacturing/controls engineer by trade but am educating myself on drafting as clearly...

So studying this drawing, am I correct to say that the feature control frame is referencing Axis Datum A and the center axis of the nut has a tolerance of +/- 1mm from said axis?

The features that are referenced from this datum point in the drawing are assembled before, after and simultaneously to the nut bracket. What I want to do is locate off of the bracket itself for assembly so the weld seem is consistent. However I am getting resistance since the nut is a datum.

Thanks for the input. Are you able to access the image through the link I attached to this one?https://files.engineering.com/getfile.aspx?folder=469e35d3-628b-4916-8d6c-fb3bc146d854&file=Dim.JPG

I am relatively new to GD&T however I have read much about it. I have an assembly that appears to be using the centerline of a welded nut as a datum for several other features on the assembly. The way the welding fixtures are designed, the weld nut is used to position the bracket. The movement...
