Re: SO2 control enclosure

Wow, That really came out nice! I have been plotting and planning a new control box, your build is very inspiring. If you go for lettering, it would be awesome to see some pictures of that too.

Also, What spindle are you using? Makita?

Thanks!

Re: Material Advice

The Inventables PCBs are FR1, which is phenolic impregnated paper, not FR4 (epoxy/fiberglass). They are much better for isolation milling, but not a good structural material. Ah, thanks for the correction! Also, I found a great link for a quadcopter project that someone did using FR4. He even poste...

Re: Material Advice

Hmmm... Hard woods might do the trick for that, though they will add considerable weight. I would consider: -Thinner aluminum sheeting, cut and drilled on the shapeoko, then bent and riveted into a monocoque design. Thinner aluminum is easy to cut and drill, and monocoque is crazy strong. Airplanes,...

Re: Cutting Aluminum

The torque on the quiet cut spindle isn't huge, so you will have to go a little slower than large mill specifications. I would highly recommend using a tool calculator to figure out your feeds and speeds! These are based on tried and true methods for mechanical engineering and manufacturing... and t...

Re: Aluminum extrusion for outdoors?

You should be just fine, Aluminum extrusions are generally anodized, which makes it pretty much weather proof. When you install it, it never hurts wrap something protective around it until its ready to go in. Scratches in the coating are easy to see. The slots on the side are perfect for acrylic or ...

Re: Aluminum Knob

Problems? Not at first. However last night I milled a larger knob and long story short, my bit was destroyed at the very end. All "4 corners" of the bit completely sheared off. I think I know what happened; my dust shoe and vacuum collection got clogged up. I had several small aluminum piles of deb...

Aluminum Baseboard

This was a shop project I created to make a super sturdy base for my Shapeoko2. I wanted to use coolant on my cutting projects, but the MDF threaded wasteboard became a sponge and warped once the coolant leaked onto its surface. I also really like the MDF threaded pattern with the clamps, but I foun...
