Holes
The last job was to disassemble the whole unit and drill 6mm holes at various places throughout the frame to allow air and steam to escape when it gets hot dipped. Putting the holes on the bottom also ensures that water can drain out later. Make sure that there are no enclosed areas because the heat of the hot-dip bath can cause the air to blow out explosively.
The final size of the cage means that I have to remove the rear door of the trailer but that is no real concern. I miscalculated the width of the end that fits between the sides because I forgot to account for the 4mm mesh added to each side. This meant that I had to use a hammer to get it to fit. However the upside is that it doesn’t really need much tethering to the trailer. Later I will fit thinner sides to the trailer and alleviate the fit.
This is not the end of the process. The pieces will now have to be hot-dip galvanized, but the nearest hot dip is an hour and half away with a two-week wait, so that is a job for another time.
