Week 22 - Steelwork

The company I work for also comprises a steel lasercutting company based in the same building. The benefit of this was that I was able to draw up some steel parts for the van and get them cut and welded at work.

After lots of research into gas lockers, I decided that the commercially made ones were unsuited to my needs and also expensive at £100-£300 each. I also struggled to find one which would fit two Camping Gaz 907 cylinders.

Camping Gaz is a butane/propane mixed gas which is the only bottled gas readily available throughout Europe (it is more expensive than other brands such as Calor though). I will house two bottles inside the van under the hobs. 

After drawing my own box up in Solidworks (a 3D CAD system), I was able to get it precisely cut, etched, folded and welded up in a couple of days.

Note that I followed these points to ensure my gas bottles were stored safely inside the van:

• The gas bottle must be sealed in a separate area from the living area of the van (i.e. a gas locker or under the van chassis). I fitted a tight seal to the lid of my gas locker to ensure gas will not escape.
• The bottle should be fitted upright with the correct regulator to measure the amount of gas being released from the cylinder and to isolate the gas when not in use. I also fitted a valve outside the locker as a double safety check.
• There should be a drop out position for any potentially leaking gas at the lowest point (at least 1000mm2 in area) which goes outside the van. Remember the gas is heavier than air so will generally sink.
• There should be a drop out for gas which may possibly leak after leaving the gas locker (to the cooker heater etc). Mine is 750mm2.
• The locker should be made from a strong, inflammable material (obviously) and secured as firmly as possible. Mine is 2mm Mild Steel. 

As well as the gas locker box, I also got the locker lid, a small plate, and a stainless kitchen splash-back (all etched with Vanny’s adopted logo). The kitchen splash-back is sized to fit exactly to the kitchen units and also has two folded shelves incorporated in. This will protect the carpeted walls when cooking and washing up.

Together, these parts would normally cost in the region of £100 but I was lucky enough to get them made for free and I am very pleased with how they turned out.
