    Bump Tube Form Standard

    Hello All, We're finding it difficult to source the specification for what the aftermarket is calling a bump tube fitting. This fitting was popular on USDM brands for several decades and might still be used on some legacy vehicles like Ford's E-Series vans. Regardless, the best I can research...

    Oil Pickup Tubes - How do they do this?

    Hey all, I'm not sure where to post this. It's an automotive part, but it's also a pipe and concerns manufacturing techniques. Does anyone know the name of the crimping process for this outside ring? Most google hits are returning hose assembly tools, and I don't think it's radial crimping. If...

    Internal Planar Continuous Feature

    Hey All, Y14.5 R2018 permits the use of continuous feature on external planar surfaces now. However, my engineer's drawing I'm reviewing has applied it internally. Intrinsically, this makes sense in what it intends, but it's not explicitly explained from what I could read in our book so I...

    GD&T - Edge-Bonded Gaskets

    Hello everyone! It has been a while since posting here, but I need help outside of the ASME Y14.5 book. First and foremost, ASME Y14.5 R2009 or R2018 is being considered, but R2009 is favored because of the cleaner dimensions (title block tolerances still permissible). This gasket will be...

    Reading Wind Speed for Heat Transfer Wind Tunnel

    I am in a predicament: Would you use an anemometer or pitot tube with a pressure transducer to collect wind speed measurements in a low speed wind tunnel? Here's the catch: This is a heat transfer wind tunnel, specifically for heat exchanger rating, therefore the air passes through the entire...

    Best DAQ for Thermocouples and 4-20 mA Current Loops

    Hello all! As the title implies, I'm looking for your favorite serial modbus DAQ devices that y'all have used with pleasure and worked with over the years. We need to replace our OMEGA Engineering D8400 since it decided to not have reliable pin-to-board connections anymore: YT Vid if Curious...

    Qualifying / Testing Wax Thermostats

    Hello all! We have samples of a new wax thermostat we are looking to integrate into our product line and I believe it would be wise to test these separately (outside of the products they are to be used in) prior to them being implemented. We also test customer products and would sometimes need...

    Designing for Wind Tunnel Test Section Velocity

    Please copy and paste my post if that assists responding. I am trying to work backwards by selecting a target test chamber velocity to design a wind tunnel around. I want to revamp our current system as minimally as possible which means using the same fan and the current settling chamber and...

    Should I Intervene?

    Hello All, I am the only mechanical engineer at my company, but I am not the one that is always gone to for engineering things, whatever. Point is, I have noticed that my boss has decided to task one of my coworkers with testing various rubber hoses and how they perform with fuel permeation...

    SAE J429 Grade 5 Hardware

    Hello All, I was looking at our parts here at work a few months ago and realized that there might've been a somewhat significant, overlooked detail during the early years of the company. We use Grade 5 screws with suspension parts. These suspension parts are sway bar end-links (see image). I...

    ECO Rubber Hose and Crimp Fittings

    Hello All, I am trying to figure out how much to crimp an Epichlorohydrin (ECO) hose down onto a fitting. I'm not looking for numbers, this is all just conversational technical discussion. Our ECO hose has a Viton liner bonded to it as well. With respect to cross-section thicknesses, the Viton...

    Oil Reservoir for Heat Exchanger Testing System

    We have a heat exchanger testing system whose reservoir is a cheap food fryer, with a sheet metal lid that has pipes welded through it for inlet and outlet. The heat exchangers that we test overwhelm the heat output of our fryer, even after applying duct insulation to the tank. I brought this...

    Heat Exchanger Testing System

    Hello All, I’m beginning to add new components to our testing system that has been through several upgrades already. This system is designed to test heat exchanger and oil thermostat performance. For the scope of this post, I will be concerned with only the heat exchanger. We use an electric...

    What are you thoughts regarding these fasteners?

    Hello all! This is my first post on the forum; I've used this forum countless times to help me in my line of work. Hoping I can get some general feedback on these custom fasteners. We're an automotive, aftermarket performance parts company and we recently decided to purchase some hardware from...
