Siesta Fiesta (Part 2: Having a Fit)

I'm so glad for the 180 degree change in weather status since the weekend. It allowed me to move my

mass of lumber and dirty business outside and continue on with my initial project in the sunshine. The hammock stand project has gone through a few dozen mental revisions, and I've had enough slight mishaps and mistakes occur to educate me a little better, nothing so serious that couldn't be corrected with a little innovation. In fact, some were welcome; they helped make me see a clearer vision of a version that would satisfy my earlier stated objectives. It actually made me see how I could make a convertible setup with just a changing some parts which can make two versions of a frame setup. They are:


Version #1 – The original double-mast version. The one made for being used for camping and the like. It's the form I'm working on now. So far, all the segments I cut can fit in the trunk of the car; so I reached the second objective.

Version #2- The deck version. A version that saves even more deck space, and requires the need of

only a single mast point. The plan I have in mind still conforms to my first constraint of having no permanent attachment to the exterior of the building. This version technically requires even less material than that of my original plan, thus passes the imperative of approaching the goal of using dMass (I may have to borrow that spare wood to make corrections).


My greatest successes at this point are:
  • Minimum of actual numerical measurement – I've only used my measuring tape about nine times. That was mostly just to get a rough overall assessment of how large it was going to be. The actual fabrication was done mostly by using a bevel gauge, a marking gauge, the straight edges of a roofing/combination square, and edges of the cut wood itself. This yielded for me . . .
  • Making the snuggest, tightest tenons that I've ever made using soft wood. I'm impressed that I've worked myself up to having this sort of skill with mere hand tools
  • Except for carabiners and eye screws attached to the hammock, it still no nails or fasteners holding the frame structure together
  • Inclusion of a middle extender piece, to adjust by replacement of only one section of wood to account for the hammock fabric getting stretched, or if the hammock itself gets damaged and needs to be replaced entirely
  • Only one cut/splinter so far*
The mishaps and failures so far are:
  • Making the snuggest, tightest tenons that I've ever made with soft wood. I'm concerned about them being so tight that the extra strain may cause splitting and cracking around some critical pressure points on the frame. I have yet to test it out. The super-tight joints and mortises also keep my objective of an easily collapsible system (with a couple whacks of a hammer) for the sake of storage from being realized.
  • A rapidly dulling ryoba saw that is finding too many knots in the wood. I noticed too late that some sections between some larger knots have looser wood fibre and would have an easier tendency to crack. I may have to dip into my reserve and buy some extra lumber to correct for these defects.
  • I made my mast tenons perhaps too narrow. I think I need to fashion some sort of reinforcement struts as a correction. So much for the idea of tensegrity
  • I made a poor choice for the kind of joint to use to bind a middle extender segment. This "bird's mouth" with locking pin set up wasn't a good idea, plus a loose knot I exposed now makes it inadequate. It is at least correctable, and there is enough of an end to spare to fashion another more stronger configuration
  • 
    One of my boo-boo's
    I actually needed a power tool; specifically, a drill to bore some pilot holes for eye screws. I'm thankful that I have a kind neighbour who allowed me to borrow his.
So, I'm still stuck with doing these revisions and corrections piecemeal, and I'm not finished this yet. I guess there will be a part three . . .
What it will look like once finished.
Ella is in the background, awaiting the
chance to test this thing out.


*- I've discovered the hard way that while on blood-thinners, a simple brush with one small saw tooth on a fingertip can make the place look like a murder scene. I hope to be off these things by this month.
