 Its a warm and misty morning. Before I get onto the skills or in my case lack thereof I'll share a few snaps of murky things.

The Neeps are showing well.

It appears we have a very large Mole.

The barley has survived the storm.

Now to the lack of skills. A short while ago I started playing with the stress analysis thingy in FreeCAD. I thought if I made an exhaust manifold then I could run a thermal and mechanical test. I then got distracted and started thinking of an equal length pipe system. Constructing any sort of system is a challenge. There are few tutorials for FreeCAD and many of the ones out there are next to useless. It's a matter of clicking things and waiting to see what happens. 

This is one of four header pipes with the head flange. The idea is that one starts with the longest and then using the same length of pipe put extra bends in until you get to the shortest. The old way of doing it was to use a piece of 1/8" malleable wire bend it to suit then using the same wire do the other three. Then you bend, cut, chop and weld until you have your pipes that hopefully fit. This pipe is swept along a spline and there is no way to constrain the length of a spline.....It's not how they work; should anyone know differently then I'll be delighted to know.

This is the four into one whatsit.

It would do the job but I have an idea for another version that would give a cleaner flow. That's another thing that FEM can do. I can see this keeping me amused for several hours yet.

It appears the Batflu death statistics are grossly exaggerated. Who would have thought it? It's a good job those responsible work for government as they wouldn't last a week in the private sector. Useless tossers.

Have a great weekend.


  1. You've just given me an entertaining few minutes reading up on moles as we don't have them here. Have you applied castor oil and eliminated wet areas? Then I had a wonderful laugh when I clicked on how to get rid of moles and realized it was referring to moles on the skin. Thought applying iodine to the mole to kill the cells inside and taping garlic to the mole to break it down from the inside both sounded a bit extreme. A crop of barley is always a pleasure to see.

    1. Pauline, the thing that did this is a subsoiler type thing for burying alkathene water pipe. We have moles here but they are a little brown furry creature about half a foot long.

  2. I was going to say a bit of subsoiling last night but never got around to making the comment. I also wanted to say told you so, not meaning you, about the batflu stats. Of course they are wrong, but what an idiot government to have gaily let it go on to its own detriment. They really are brainless.

    1. Rachel, it appears stupidity afflicts half the worlds politicians, an idiotic reaction to a bit of flu. A case of the cure being worse than the decease. There's something else going on but I'll be buggered if I know what it is.
