I Had an idea bouncing around in my head for a while of how I could build a auto turn for a cabinet machine, My wife would tell you that the idea had a heap of room for bouncing in
Well the only way to give a an idea a chance is to start building so this is what I came up with. A lot of this machine was built on the fly so to speak. As I hit a snag I thought about it and worked out a fix.
In all I estimate that it took close to 4 weeks to build the aluminium rack, design and build the auto turn circuit, construct the cabinet and fit every thing up into it. The thermostat was kindly given to me by a fellow incubator nut from australia that designed and built the circuit.
Chipboard loves to soak up excess moisture and swell and go soft, all of the butt joins are assembled with silicone caulk in the join and the stuff that oozed out was smeared down to a nice finish. This seals the join and prevent any ingress of moisture into the join.
I used a product called INOX to lubricate all the pivoting and sliding surfaces to ensure the minimum of binding issues, INOX is an Australian product that is based on the oil from sheeps wool (Lanolin) and it is rated as food process safe.
