    Bump Tube Form Standard

    Thanks for sharing that info; would have never guessed mobile air-con standards. That allows us to be certain about the O-ring versus tube diameter when designing this billet adapter fitting.

    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

    Apologies for the lapse in replying. CF was removed because I thought it was also redundant. I added extension lines to the drawing to reduce assumptions. This is a real part we're working on so I couldn't share the whole thing. I also didn't have time to create a basic model to show what I...

    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

    Considering we're making a generic version of an OEM gasket design (so don't judge the weird parting line choice right now), AND ignoring our written requirements on the drawing, do the highlighted getols below convey a completely filled sprue and perimeter?

    GD&T - Edge-Bonded Gaskets

    3DDave this all in one method sounds like it would work well on simpler gaskets for sure, and if a language barrier wasn't a concern too. That is likely how they check our completed part, but I am going with btrueblood's advice. btrueblood I appreciate the helpful feedback for sure. We'll send...

    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

    Autodesk makes their own CFD software of which you can import an Inventor model, correct, but our reseller has not included that in the collection that we use. Solidworks is all internal to the actual software; but way less detailed than something like STAR / ANSYS. Kays & London actually...

    Reading Wind Speed for Heat Transfer Wind Tunnel

    I wish we had Solidworks so I could use their paltry CFD; Inventor Professional still doesn't have something basic. My boss likely won't pay to send this off either.. We'll see if NTS can help us out, otherwise we're going to try and see what else is out there, or I'll finally get to finish...

    Reading Wind Speed for Heat Transfer Wind Tunnel

    Flow nozzles didn't end up being efficacious. Due to the test chamber size versus the current fan we're using, the Helander Metal rep said I'd be better off with anemometers instead. Since that means more money for my boss to outlay, we're looking at third party testing finally, even though we...

    Reading Wind Speed for Heat Transfer Wind Tunnel

    I understand needing just one for the thermal rating aspect, but per air's pressure drop through the core, I was thinking that is why I would need another. I suppose if I am metering air with one nozzle to understand the flow right before the H.E. then I could just use a pressure transducer to...

    Reading Wind Speed for Heat Transfer Wind Tunnel

    MintJulep I've seen that type of thing before but forgot to file it in my memory for later research. I've only seen them on extremely large wind tunnels or like outside of coastal weather station maybe; can't recall for sure now? If I'm thinking correctly, these things typically sit in the...

    Reading Wind Speed for Heat Transfer Wind Tunnel

    I also forgot to mention that this is a computer instrument testing system, therefore all options have to be able to transmit analog/digital signals.

    Reading Wind Speed for Heat Transfer Wind Tunnel

    rb1957 I suppose that is a decent way to do it, although the initial X-Y point traversing is really what I'd like to avoid. I will for sure need two stations for this, seems like I forgot to make that clearer in my initial post. VEBill I would perform those experiments on the heat exchangers...
