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...
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...
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...
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...
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...
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...
Howdy all,
I was looking for a set of switches, 813387-3/-4/-5 and they each have a long list of PMA parts. Removing duplicates there are 23 separate PMA parts that are common to all three of these parts. These 23 PMA parts are approved as alternates for multiple OEM parts. In fact there are 25...
Howdy all,
I'm reviewing a test plan to replace a P-seal on an aluminum air-oil heat exchanger. It's calling for a 2000 deg flame for 5 minutes to show fire resistance. I don't think a fluorosilicone/glass fiber P-seal would survive 5 minutes at 2000 degrees and I wanted a sanity check to see...
Howdy all,
I'm looking for a method for creating pneumatic/hydraulic schematics to document some existing equipment. I could get the full version of Visio, or I was also looking at Libreoffice draw, which I found a few symbol libraries, but a bit sparse. What are the other common tools for...
Howdy all,
I'm designing the tooling to test a pneumatic motor and I'm stumped by this connection in the pictures below. It's a 2.25" OD with two grooves. The first grove, the larger one I thought was an O-ring gland, but it's a bit narrow at .091 inch and way too deep at .125 inch. The second...
Howdy all,
I have a small o-ring (-010) that uses a cap seal (see pic below). The cap seal P/N is part specific, and I was wondering if there was a standard for similar cap seals. I found a couple of websites that sell similar style O-ring cap seals such as Mykin inc and Gallagher fluid seals...
So I'm going through a CMM for an Airbus Component and they reference the following materials:
Z 100C 17 Steel
APX 4
AU 2 CN (T6)
UA 10N
I tried a couple of these and didn't get any useful search results. Could anyone narrow down the search range for me so I can find out what these materials...
Howdy all,
I'm designing tooling to test a hydraulic servo actuator. To actuate/measure the position I have a .156 rod extending out of the pressure enclosure. But at 3000 psi, this rod is still going to experience 50 lbs of force. I had originally designed it with the actuation separate from...
Howdy all,
Using Solidworks 2021 SP3.0, but this has been an issue in previous releases as well.
I have the drawing standard set as ANSI in the document properties. But it uses ISO (I think). If I switch to any other standard and apply the changes then switch back to ANSI, it then uses ANSI...
Howdy all,
So I have a Sofrance (Safran Group) CMM that calls out connector type NSA 8676 #6 for connection to port NSA 8677 #6. I can find the NSA 8676 bobbins for sale, but I want to know more about this fitting and can find nothing in the way of specifications. Can anyone provide a copy of...
Howdy all,
So front line carriers often prohibit PMA parts for repairs without approval. Some PMA parts are approved by Identicality per a licensing agreement, and these usually have the same part number. It is a PMA part and should say PMA on the ID tag and the 8130, but with the same P/N I...
Howdy all,
I'm looking for alternatives to Dichloromethane (DCM)? We have a callout to clean the filter in an Starter Control Valve using DCM in a sonic cleaner. So this filter is on the upstream side of the starter valve and I'm guessing just used to prevent contamination of the regulator. DCM...
I'm designing a rivet set tool to drive MS20470A4 rivets to back up the machine head in an area with limited space. If I had more space I would purchase an SM201-4704 rivet set or similar, but instead I want to just machine a recess to fit the shape of the rivet in my tool. I have designed the...
So in a lot of drawings there are internal sharp corners that I'm fine with as is. The stresses are not critical and there are no clearance issues. I want to leave the internal sharp corner as is and I don't care about the dimension of the corner. This gives me a dilemma. If I leave it as is, a...
Howdy all,
I'm creating a test setup for a starter motor and I want set the input voltage on the supply to 25V ± .5V and then turn it on and measure the inrush current which could be up to 800 Amps. I'm not sure what kind of power supply I need for this, and most of my searches are pointing me...
