    Anyone have a copy of British Standard EN29543?

    Thank you. That's enough for me to get this on order. -Kirby

    MS51990 lock ring serrations

    I was dealing with Beam Seal fittings that had this locking feature. Here's a series of videos on how to cut this recess using different types of tools. -Kirby

    Anyone have a copy of British Standard EN29543?

    Howdy all, I’m trying to find details about a solder referenced in British Standard EN29543. The only reference I could find online was from page 337 of Materials for Engineers and Technicians by R. A. Higgins. This list (see below) is incomplete, and I was trying to find information on the...

    Is there a database to go from a materials analysis to a material?

    MintJulep, That steelnumber website was what I was looking for, but it seems kind of broken. If I put in 85% Iron and 12% Chromium it comes back with no hits. I could put one variable in at a time and get a hit. Maybe I don't know how to use this query function right. Dgeesaman, That's...

    Is there a database to go from a materials analysis to a material?

    Howdy all, Is there a website or database where I can punch in the results from a material analysis (metallurgy report) and get material candidates that match that chemistry? Matweb has something kind of like this, but you need to put in a range but I want to go the other way and put in a value...

    If improperly done....What are we including with this statement on the major-minor determination?

    MNLiaison, Thank you! That is exactly what I was looking for. That's a great discussion of why the wording is as it is and suggestions for clarifying. -Kirby Kirby Wilkerson Remember, first define the problem, then solve it.

    If improperly done....What are we including with this statement on the major-minor determination?

    Howdy all, So I've been wondering about this for years and have no good understanding. One of the determinations for major minor is: IF INPROPERLY DONE, WOULD THIS ACTION APPECIABLY AFFECT AIRWORTHINESS? I just don't get this question. If improperly done...anything could fall under this...

    Is there a source for beaded flanges per AS5131?

    The motivation is repairing damaged beaded flanges on existing heat exchangers. We may just need to do the rolling ourselves. The ATS145 from aircraft supply looks too small, one of the flanges is 6.5". But that K2 tool might fit the bill, I guess i was avoiding the cost of the tool and time...

    Is there a source for beaded flanges per AS5131?

    Howdy all, I feel like this should be an off the shelf component. But I can't find a source. I want the rolled beaded flanges per AS5131. The standard has sizes per a table. I just keep coming up with places to buy the beading rollers. Is there no shop that just cranks out the tube ends so we...

    Good wording to state fabrication based on model geometry.

    This turned into a great discussion. Thanks everyone for responding. I agree having a drawing/model for quality to inspect to would be an important piece of the puzzle. For this application I'm not concerned with remodeling for CNC since this is going to be 3D printed, the model really is...

    Good wording to state fabrication based on model geometry.

    I like the idea of stating the model is basic and providing a profile tolerance. Since this is 3D printed, that really is the controlling reference. I was avoiding the Digital Product Definition Data Practices since that is more focused on getting away from paper drawings and this is more using...

    Good wording to state fabrication based on model geometry.

    Howdy all, What's some good wording to put in the notes of a drawing to state that the fabrication is controlled by the model so drawing details are incomplete. My thoughts are: "Fabrication of part is controlled by model geometry contained in file "PARTXXXX.STL" derived from 3D CAD model...

    Hi ,Aero buddies need attention of

    Without even knowing what software you are using it would be hard to help. I would suggest going to a forum for that specific piece of software. There are a few here on ENG-TIPS in the engineering computer programs for the most commonly used applications. I suggest more detail about the type of...

    Is the flow correction needed?

    Howdy all, So I've been unsure of this for a while, but testing heat exchangers for leakage or pressure drop we regularly measure air flow, record it in units of mass flow, and then do a correction based on temperature and pressure. I think this makes sense if the measuring device is recording...
