Sous Vide cooking – steaks

This past summer I talked Teal into letting me get a an Anova Culinary Bluetooth Precision Cooker. It was a bit of a stretch as she once again thought I was crazy and then crazier still when we then went to Costco and picked up an enormous roast.

The roast was portioned out into 1.5-2″ thick slices and seasoned with salt, pepper, garlic and fresh thyme, marjoram and oregano. Each was then vacuum sealed, dated and thrown in the freezer, except for  for the first dinner.  First steak was cooked at 129 degrees for 90 min. We have since moved to 130 for 2 hours as the sweet spot for these steaks as our standard.

Prior to grilling remove as much fat as you can. This prevents flare ups and a sooty / bitter exterior. You want a clean crisp dark brown but not black surface. Grill needs to be blazing hot 700-900 degrees for 2-3 min per side. I use the Big Green Egg but you can get similar heat by placing the grill right on top of the charcoal chimney.  Note that the sliced steak photo is NOT the way to go – trim the fat and life is much easier.

The technique works perfectly whether doing 1 or 6 of these . Perfectly consistent and fork tender.


The Serious Eats and Anova web sites provide lots of ideas for Sous Vide cooking.  I also strongly recommend: The Food Lab: Better Home Cooking Through Scienceby Kenji Lopez Alt. I first ran across his posts on Serious Eats and the book is a must have for anyone who is looking to go from just experimenting a bit to really understanding what they are doing in the kitchen.

CNC touch plate

The CNC router has achieved functional status. That is I can now with modest effort actually make useful things. These can be furniture pieces or parts for the router or other tools.

One of the hard parts has been zeroing out each of the  axis. X and Y i have been doing with a standard edge finder. I particularly like the 1/2 inch diameter ones like this one: Brown & Sharpe 599-792 Edge Finder Single. The smaller diameter (typically .2″ diameter touch) are bit small for woodworking due to the rougher surface of the wood and the large ones seem to be easier for me without false indications of the edge.

The way I am currently setting up my fixturing on the CNC table, I have a left size (x axis work zero)  fence and some movable stops from Rockler in the table slots. This works out quite well. I measure from the stops / fence to the home position and modify the zero references and I am off and running for several projects.

The hard part has been easily zeroing out for cutter height. This has to be done after each tool change and is just plain tedious. So I was determined to set up a touch plate and have that working with the Mach 4 controller software. This took a little bit of time. First was getting the Mach 4 “Probe” input  working.  It requires at least version 2803 of the Mach 4 software which I am using with the Ethernet Smooth Stepper (ESS) version 130 software.   The touch plate is simply a block of acrylic plastic about 3/8″ thick  with a sheet of brass mounted on top and connected to the “Probe” input.  The router spindle itself is grounded for safety and this conveniently completes the circuit for the touch plate.

The idea is to drive the Z axis down at modest speed until it touches the plate, and then it backs off slightly (~0.1″) and then moves downward very slowly to touch again for the final height.  Once complete, the height of the touch plate is subtracted off and you now have the height of your base (spoil) board on which the project will rest. This is all great in concept but the Mach4 software does not complete this for you. So I had to modify the UI / Screen set, add a new button and some scripting to do this.  This is one of the points where having an active user community helps tremendously. Searching for help on the Mach4 forums I came across a thread on this topic and some script code from another user “DazTheGas” see the message thread.  I had to convert from metric to inch measurements for the movements and enter the height of my touch plate (.487″). This works great. Much easier than manual zeroing and I don’t have to worry about breaking small diameter tools or chipping the carbide on bigger ones.  You can see the video of the process here


Lembeh Straight Diving 2015

In October of 2105 we went to Indonesia with the group from Underwater Connection. The primary destination was Lembeh Straight. Lembeh is well known for what is often referred to as “muck diving”. It is really that you are diving on a black sand bottom. The depths are typically quite shallow (<30 feet) and visigbility is not great. The slightest movement can easily stir up clouds of debris and swirling sand which takes minutes to settle back down. The goal of this diving is to see the many rare and unusual critters that inhabit this area.  It is macro photography heaven.

Blue Ring Octopus

We stayed at Kasawari Lembeh resort. This is a small boutique resort with excellent service and attention to detail. One of the key details was the small groups on the dive boats. Typically 6 divers to a dive guide.  The guides are a necessity. We were looking for critters that were well camouflaged and often the size of your fingernail. We often wondered : “How did they see that?”  However, after a few dives we started spotting some on our own but still not with the regularity of the guides.

On many trips we feel lucky to see an octopus or a small group of squid on a trip. Here we had the fun of seeing as many as 5 species in a single dive! These included coconut octopus, mimic octopus, wonderpus, blue ring, flamboyant cuttlefish and more.  Dozens of nudibranchs (including mating couples),  and an endless variety for shrimp and crabs.

A sample of the photos can be found here: Lembeh Straight Critters 2015

These were taken with  a Nikon D300S, Nikon 60mm macro, Subsee+10 wet diopter, Ikelite housing with glass flat port, Ikelite DS125 strobe and a Light and Motion Sola 600 as a focus light. The side lighting pf the focus light was extremely helpful to find the target and actually provided nice fill in of the shadows.  The overall murky conditions were best suited to macro. I did not get a chance to do any significant wide angle shots. For those I use a Tokina 10-17 and Ikelite 8″ dome with a single strobe and diffuser.

Rebuild in progress

I am in the process of overhauling my website and postings. In the meantime you can find my old boatbuilding website here: Riviera Construction Project.

In the last few years I have been letting my projects, comments and photos get scattered. This has resulted in a mix of items on Facebook, columns I have written and   various forums with the unfortunate consequence of not having a single place to go and find my prior posts which are located at:

  • Glen-l boatbuilding forum  – I was active while building and did a column for the monthly newsletter for a few years
  • Wisconsin Woodworkers Guild – I wrote a monthly column while I was president.
  • Facebook – Lots of posts , notes and photo albums including the majority of my dive photos, but not very accessible to the general public
  • Youtube – I have a Youtube Channel that will be gaining more content. Currently mostly dive videos.
  • Southbend lathe yahoo groups – Superb resource for those interested in South Bend Lathes . Huge help when I rebuilt my SBL 13
  • HID Dive Lights yahoo group   – This is where I documented much of my dive light builds
  • Hobby Machinist – Another great resource and most helpful while I rebuilt my Bridgeport Mill
  • CNC Zone – Current CNC router project resource

and more – you get the idea. Lots of scatter.

So now I will be consolidating everything back here. It will take some time to gather the various pieces back as well as get the new content posted.

The impetus for all of this is my newest project. It is a CNC router. This is another scratch built project.   I want to document the build and resources as I did with the boat and not just have it in another web site’s forum.
