Nick- Pardon my ignorance here, but why are you saying i'd want to heat treat? I really don't think I need the plates to be that hard, but I just need something tougher than the aluminum parts that will be inspected. Is it just for dimensional stability? I like that you mentioned grinding...

Thanks for the replies. Sorry for double posting; it won't happen again. You're right, Mike. I'm looking for magnetic so that a surface grinder can be used.

Hello- I am designing a series of inspection plates for a family of aluminum parts. Each inspection plate will hold an array of 25 machined, cylindrical (2-3 in. o.d., .375 in. tk.) aluminum parts. The plate will hold each part in a 3 pt. kinematic seat machined into the surface of the plate...

Hi- This is probably a simple question, but can someone explain the advantage of using an o-ring gland seal as opposed to a face seal (either gasket or o-ring) for a pressurized flow connection? I think it has something to do either with the exposed surface area of the seal or in the way in...

Hello- I have to start by saying that this might not be the correct place to post this, but I couldn't find a more appropriate place in my searches. So here's the deal: I recently took a job as the sole mechanical engineer for a small medical device OEM, and we basically run things like we're...

So I just found out about pem studs,and I think they may be exactly what I need.

Hello- I'm trying to figure out how to attach threaded post to a flat piece of sheet metal part so that one side of the sheet metal would still be flat, and on the other side, the threads would still be accessible for fasteners to tighten up near to or even coincident to the sheet metal. Think...

Kenat- I attached a pic for you to check out. The 2 springs you see in the slider may be replaced with set screws for better control.http://files.engineering.com/getfile.aspx?folder=af0b1104-6843-40f3-a9b1-f440c00c1e40&file=pivot-slider_pic.JPG

Thanks everyone for the great input! For my design tho, I guess I took the most from KENAT's suggestion, as small size and simplicity are very important. As it's modeled currently the joint will utilize a 2 piece plastic (nylon 6-6 probably) slide. The assy. is about 3X longer than it is...

I need to design a joint that slides while it is pivoting. I can provide more details if needed, but here are the basics: -This is part of a precision motion imaging system, so eliminating slop or play in the joint is highly desirable. -The system will be driven by a reciprocating motor, so...

I need to put a 7"X10" window in a chamber that will experience pressure up to 2 atm gauge. Due to chemical exposure (amines) and high operating temperature (105C+), I have been unsuccessful in finding a transparent plastic that I can use. So i am considering using thicker (.5 in) laminated...
