The RTD temperature probes have been ordered.  I also ordered a few extra normally closed contractor blocks for the panel switches.  These will allow me to setup a safe start interlock for the panel.  I spent the extra money for 25′ of 3/16″ walled 1/2″ ID silicon tubing to avoid any kinking issues.  Finally I am making a home made vent for the boil kettle based on this post.  It will be built from a 30qt stainless steel mixing bowl, a 4″ duct fan, and dryer hose.

Volt/AMP meter hole has been cut.  The 5/8″ dip tube has also been cut.  It was designed to fit entirely under the false bottom including the bulkhead.  I left a half of an inch between the bottom of the dip tube and the bottom of the mash tun.

Real progress has been made now that the punches have arrived. Doing all of this with a step big is possible but I would not recommend it.  I started each hole with a 1/8 bit then used a step bit to widen it to accept the lug for the punch.  The dremel also got a bunch of work.  I cut the factory grounding post off the panel to make more space for the buzzer and the holes for the PIDs and timer.  I still need to dremel the hole for the volt/amp meter and I need to cut the MLT dip tube to length.  The sight glasses were installed with a step bit.  So far I have only calibrated the boil kettle.  The element is covered with 2.5 gallons and the whirlpool fitting is submerged with 5 gallons.  I placed my newly built kettles on a 72″x24″ stainless steel prep-table.  Since the temporary brewing space is still carpeted at this point I added a catalina cactus carpet below to catch drippings.
