    Swaging guidelines

    Does anyone know of textbook type tables that give guidelines to hole size, material thickness, and pin or tube diameters for swaging operations? Something akin to what you find for riveting.

    Rigid vs floating vibration measurement

    We are looking for the correct means of measuring vibration in terms of should the object be rigidly mounted or can it sit on a foam pad. The objects are either small psc motors (42, 48 frame) or motor/blower wheel assemblies. Based on different person's experiences, we debate on whether the...

    Alternate tests to hi-pots

    Looking for alternate ways of verifying a hi-pot failure, aside from tearing the motor down or rehipoting. When a hipot failure is found, I'd like to verify if it the findings. You could tear into the motor to look for stray wires and such, but you can get into warranty issues with the motor...

    Mysteriously Moving Controls

    A couple of us are co-creating a form in Excel with check boxes, drop downs, etc. What little functionality we have we wanted to keep simple by triggering macros off of the controls rather than writing code, therefore we initially decided to use control objects rather than form objects. What's...

    Assembling a deck of cards

    Looking for tips on how to create an assembly of something analagous to a deck of cards. It would essentially be one card inserted X number of times, with different configurations being the number instances. What I'm looking for are tips on creating the mates without repeating the steps dozens...

    How to use sound quality for evaluation

    How can sound quality be used to solve a noise issue vs using sound power/sound pressure? Situation where us vs "other guy", our product has a better sound pressure spectrum, but theirs "sounds" better. We look at the narrow band spectrum to look for the exact frequencies, and across the board...

    Rotor coatatings

    I recently came across this thread, thread237-82751 , and found the last comment to be very interesting. Has anyone heard of anything like this happening in the field, where a paint is being used that outgasses chlorine at temperature? Opinions?

    Electrical Noise - Sleeve vs Ball Bearing

    We have an application utilizing a PSC motor with a type of triac type speed controller. The application is a motor in a blower, and the speeds run dictate that a ball bearing design should be used. Situation is that if a motor with a ball bearing construction is used, the motor is noisy (low...

    Limit style tolerancing vs bilateral

    We are in the process of writing drafting standards, and one of the debates is in the method of tolerancing. The majority of our old drawings had ± tolerancing, with some limit style tolerances. The group working on the standards is heading towards standardizing on limit style dimensioning...

    Graphing a function without data in a sheet

    Does anyone know how, if it is possible, to graph a function (i.e. y=mx^2) without cell data? Assume a chart already exists created from data. I want to add a line generated by a function without having to enter values into cells then referencing those cells to add the line to the chart...

    Anybody use Smarteam's Workflow

    Not sure what the best forum for these questions is, but does anyone use Smarteam primarily for it's workflow capability? What are some typical practices for creating a change request and change notice within Smarteam? Does anyone utilize folders in this practice to separate change request...

    Cancel with Input Box

    Does anyone know how to handle Cancel with an Input Box, and distinguish it between an empty string when hitting Enter? I've seen code that looks like: Sub TestInput() Dim ans As String ans = InputBox("Response:") If StrPtr(ans) = 0 Then MsgBox "You hit cancel" Exit Sub ElseIf ans = ""...

    Charting multiple sheets with arrays

    Working on a spreadsheet that imports data from text files, based on user input. For each set of data, a new sheet is created and the data is put on that sheet. An input box allows the user to name the sheet as the data is being input. All this works ok. I've also got a routine that puts the...

    Condensation in motors

    For residential, outdoor condenser type motors (think of your central air conditioners), has anyone seen a good way of preventing condensation buildup inside the motor? Many motors fail due to rust buildup caused by condensation, but I've never seen a way of preventing this.

    Quirkiness with SmarWeb

    Anybody using SmarTeam, particularly SmartWeb? We're in our infancy, and I don't think we have a clue how to effectively use it. We are using it mainly to control drawings (check-in/check-out) and basic drawing change requests. The difficulty is we structure the project into folders, and...

    What PE discipline test to take?

    I'd like to take the PE exam eventually, but I'm in a quandry as to what discipline to take. I have a degree in aeronautical engineering, and have taken my EIT. I have never even worked in anything close to the aeronautical field. My first few years was spent as more of a mechanical engineer...

    Mirroring a pattern

    Hopefully this is a simple issue. Something I know can be done with some of the midrange cad packages is mirroring a pattern, or patterning something mirrored. CATIA doesn't seem to be able to handle something like this that I can find. Any help would be great.

    System noise vs. motor noise

    I have a single phase, 60Hz, 1/2HP 8 pole motor/fan application which is experiencing a very annoying noise and vibration. Orientation is shaft down. The motor has been replaced with another of the same design, so it's either system specific of specific to the design of the motor. We've taken...
