If this is not the right place where could I ask whether somebody could be bending 35 mm (1-3/8") aluminum tubing for me? Material details: Material: 6061-T6 aluminum Wall thickness: 16 gauge Tubing outside diameter: 1-3/8 inch (35mm) The structure is very simple, just a 90-degree bend is...

Yes I have a design which is 1/5th or 1/4th of the original design -- so if anybody can still quote this or is interested please let me know...I understand the large piece is a PITA and not really cost-effective...

Ok, just as a quick update if anybody can help with this there's a way to split up the large piece into four-five identical smaller pieces so it's a lot more doable...anybody else who may be interested in quoting? Thank you.

I saw you tried to PM me -- just cleaned up my inbox. The finish on the machined surface is ball milled. The accuracy requirement is around 5 mil (based on a CNC programmed file). Is there another way to describe the finish? Size of the dish is about 60 inches around x 16 inches tall...

Hello, I have a requirement from a university research group; they are looking to build a large reflector out of Aluminium -- it's a structure which should be quite accurate (~10 mil?) on the inside while the other dimensions are not that critical. The easiest way to visualize this would...

I'm looking for a very unique job -- I need a parabolic reflector manufactured out of a metallic material (aluminum, sheet metal, copper, etc. ok). The outer x-y dimensions are 200 x 400 mm (not too small but not excessively large). However, in the z-direction I need a particular profile...

Found two images of a previous similar design, can you guys tell if these were EDM? Looks to me like they have rounded corners but I can't estimate how much they are. For reference the channel width is 0.148" and the height is 0.074".

Just to illustrate to you guys that I'm not 'crazy' with this job :-), here's a view of the electromagnetic fields as they channel through the L-shaped channel (which is composed of the thin slot in the 'outer' part and the rectangular cut-out in the 'inner' part). When we model these we...

Inner part: Outer part: The green arrows illustrate the corners that need minimal radii... Note that the two parts are not to scale with respect to each other. Thanks! /Dan

Thanks to all who replied; you will receive my e-mails shortly. I think we can live with very tight radii around the corners in those channels, something preferably < 10 mil if possible (somebody PM-ed me mentioning that 13 mil radius would be feasible but I wonder if it's possible to have 10...

Hi, The material for this would be Aluminum. Thanks! /Dan

Hi, Thank you to everybody who responded to my last RFQ. Currently, one of my students has designed a support for a small antenna project; it consists of 2 parts which should be relatively simple except for one feature on each part: Part "outer" is the bigger (blue) box is approx. 3 x...

Thanks everybody; I've responded to all who replied and we're making these right now with one of the members who contacted me here. Once it's all done I will post about the experience. In the meantime, one of my other students has a second 2-piece project with some interesting features -- I...

Thanks! Everybody has been replied to in PM or E-mail. I sent out e-mails with drawings in a number of formats (DXF, IGES, STL). Please e-mail me or PM me with any other interest or if you didn't get a response (I am pretty sure I got everybody who responded). Many thanks! /Dan

Here are some examples of what we're talking about: Box 2:

Hi, I work for a university research lab and we're very often in need of small-size prototype boxes and metal supports for our electronics projects. These are a little beyond of what a generic-sized project box would accomplish but the goal is to keep them manageable in terms of complexity...
