Hi all, I'm looking for some direction on a sensor which could be used to detect air leaking out of a plastic cylindrical shaped product. The product can be pressurized so that any small holes would be emitting some type of stream of air. I've looked into vane and hot-wire anemometers and...

@gearguru Thanks for the response. So you are saying that even with the full standard on hand (unfortunately I do not have it) the designer is still responsible for using the tolerance zone charts to determine what he/she would consider a proper fit and there is no simple solution such as...

I apologize in adavance if this is a silly question but I am just starting to understand the ISO 286 standard and would really appeciate some help with a question I am trying to answer. I am creating an assembly which uses an off the shelf linear actuator with a 4H7 hole for locating. The...

I apologize if this is a juvenile question but I was thinking about how sunglasses could be made in a plastic injeciton mold setting and began to wonder if the main frame (not the legs) could be made in a single process. What troubles me in the creation of the slot where the lens sits. The...

ivymike: Slippage using a wheel would produce too much variance for wire grinding which needs to be fairly exact. The magnetized idea is interesting though. I will have to look into it. dhengr: This is actually very similar to our current setup. Problems arise due to greasy wire slipping on...

For a current project I am looking for a way to track thin wire linearly as it is unwound from a spool, ground in a grinding machine and then rewound onto another spool on the opposite side of the grinder. The kicker is that due to the nature of the grinder, both the spools are rotating in a...

Looking for a double acting pneumatic device which both translates and rotates at the same time. The application is for being the device to be bolted to a machine then screwing and unscrewing a screw. The device would likely utilize a threaded rod of some sort and would be attached to the screw...
