As we wait for the bulk of the wing parts (mostly aluminum tubing) to arrive, in-house fabrication has begun. We can easily cut most of the 2.5D parts out of flat stock, be it aluminum or 4130 steel, on the waterjet. We also produce our own CAD for the parts that are missing drawings within the EMG-6 builders database.
Test firing the machine, first with water only followed by water and abrasive at high pressure.
Although Hawaii does not have many fireplaces, this student has managed to find one. Please contact us for our chimney sweeping rates.
The tab remains and will have to be grinded flush.
Here is a finished set of 20 Diagonal Attach Plates plus a spare. These will be used to reinforce the attachment of the diagonal struts to the leading and trailing edges of the wing.
Here we are using the provided PDF drawings to recreate the parts in Onshape, our CAD software of choice. From there we can generate the DXF files to be loaded in the OMAX layout program.
In this step the machine is homed and the z-height set.
Here we have loaded the DXF file into the OMAX program and begin laying out the 20 copies of the part. Tabs are added, the cut quality specified, and the material parameters set prior to generating the machine path.
The next morning parts are removed from the tumbler and cleaned.
What's left of the 0.125" 6061 aluminum sheet.
The cut parts will be tumbled overnight to smooth out any sharp edges.
