Home from work with my car in the repair shop, I turned my attention to the floor grate. This one cost me 2D6 sanity points, but I'm really happy how it turned out. Rather than take the easy way out I decided to try and replicate the grate from Ron Cobbs drawing seen above.
To cut these to the same length with a 45 chamfer at each end, I modified an Xacto mitre box by adding a stop and a small clamp to hold the piece being cut.
Then it was a matter of cutting them with a razor saw and cleaning up any burrs. These were glued to a thin strip to make each 'rail' of the grate.
I cut some grooves in a piece of MDF at the correct spacing and glued some styrene strips at either end.
I continued this border completely around the rails.
Behind this, I glued a sheet of styrene with slots machined into it.
This was surrounded by a second outer frame built from thicker styrene. Here is the result:
All in all, I'm quite happy with the results.
For a look at what they used in the Alien movie (among many other sci fi classics) for floor gratings have a look at the link below.
