Message In case you missed a couple of my posts in the past, I built my own CNC and now trying to make something with it.

I swore I would never polish another plenum. This seems different some how. I probably won't take it all of the way to a mirror finish

I ended up getting two sets cast for $500. The guy said if I went into production(100+), it would be significantly cheaper. I couldn't stop myself from doing a little sanding just to see what it will look like when it is smooth.

Here is a picture of the prototype standing over the new aluminum copies. Looks pretty simular... I am glad the prototype survived!

A view showing the difference between the sanded finish and the sand cast. I still have a lot of sanding left just to take out some imperfections...

Between working 50+ hours/week at my job and now teaching at a local college, I hope I'll be able to find some time to finish it!!!
