Finally, the fume hood is in the works!

I was unsure about what I wanted to do, so I sat in front of the computer and started to look into what the industry does.

I also found complete molded HDPE fume hoods, wich look fantastic, and not super expensive (300ish €)

But in the end, anything I could make was bound to be cheaper.

First I marked the avaliable space on the table.


Once I clearly saw the boundaries, the design quickly came to my mind. It had to have a closed bottom so any small spills where contained, and be easily fabricated.

A simple C shape with 30mm height arm rest, and two side plates.

At first I thought I could half cut the sheet with an angle grinder and bend it by hand, but for 700mm width, that was not feasible, nor weldable with the experience I have.

After asking in a metal workshop, bending was so cheap, I opted to have it profesionally done instead.

Next time, finished hood!
