The Writing of Serious Stuff (by )

I has been wanting to write about news events and serious things for a while but I am finding it hard, I used to write what ever I wanted and pop it on here but I become increasingly worried about offending people etc... It is really lame and very sad so I want to get back to writing what I feel needs to be written rather than worrying about what people want.

Part of the issue is that I have been told I sabotarge myself - by bringing up political stuff etc... but really I can't just ignore stuff. Sometimes I have not had the energy to tackle a subject, not had the time to research it as much as it needs to be etc... Part of the issue is that I am also bored of having/listening to the same arguments again and again. It's like philosophy - it got old at university and everyone just moves in circles and it drives me nuts!

Anyway I want to get back to writing my little ranty essays even though it means I will probably be going in an ever decreasing circle and be called Ozzel Um.

Having said that - there is now a Snobberlink Category on Wiggly Pets full of daft comics 🙂

Horse Meat and Food Standards (by )

Ok so everyone has been going on about the horse meat in the beef burgers and there have basically been too reactions 1) Oh my god! and 2) hahahahaha.

The first one tends to be along the lines of 'oh no I ate poor horseys!' which for people who eat meat is a bit silly. As has been pointed out they are moaning about the wrong animal being minced up for food. Is a horse really more valuable than a cow?

It could be argued that the horse is more intelligent but the people arguing this will nearly always be bacon eaters too and pigs are really intelligent. The other thing is that this seems horrific to the English but the rest of Europe eat horse! All the time not just when there is a cock up.

People need to assess what they are actually eating rather than burying their heads in the sand. I have friends who don't like the idea of the animals being killed but will not give up meat - they just buy bits that don't look like animal and try not to think about it. Maybe if they thought about it a bit more things like this wouldn't slip in under the radar.

This is interesting as Alaric doesn't even eat fake meat as the idea is alien to him. And this brings me to the point that though I think the reaction is silly, there is still the matter that people where choosing to by minced cow and not minced horse and the choice should be there. Not just for ethical reasons either - now I am not a vegitarian but have issues with cow fat. They make me sick weather in milk or the meat so for me a mistake like this could have serious health consequences. Say I was buying lamb burgers and they happened to contain cow - I would be getting sick and not know why. This is a safety issue.

Also if they have managed to put the wrong meat in there what else has accidently slipped in?

This mess is also going to result in a hell of a lot of food wastage at a time when people are queueing at soup kitchens and food banks are struggling to supply what is needed for all the families in crisis and that makes me want to cry or throttle someone. I know it would seem like a solution to give the patties to them but that would only work if they could be guarenteed safe otherwise you might be making a bad situation worse.

Lets hope it ends up in the bacteria vats for gas and electricity production than in landfill.

Day 2 of making the ladder (by )

Yesterday, I cut out all the bits required to make myself a ladder.

This morning, I set out on foot to visit Machine Mart and Screwfix for some supplies; a set of magnetic welding clamps, some white metal paint for the completed ladder, and these anchor bolts to attach it to the wall. As you can see from the diagram on the box, they just can't wait to be buried in a wall:

Happy anchor bolts

Anyway, it's been a long time since I last did any welding (and I've never been great at it), so I started by just tacking a few bits together to check they line up correctly with the wall. I started with the trickiest bit, the angled spacer:

Tack weld

Then I proceeded to drill correctly-sized holes for my anchor bolts into the mounting flanges, using my column drill (a very useful tool). This made a lot of pretty swarf:

Drilling the mounting flanges

Then I started welding the flanges onto the spacers. The new magnetic welding clamps (the red thing in this picture) came in handy here; their function is to accurately hold things at ninety (or forty-five) degree angles:

Welding the flanges onto the spacers

With all six of the spacers flanged, I could start tack-welding them into place:

Welding the spacers onto the upright

My welds on the flat were OK, but my welds inside corners are still pretty ropy; I had to keep chipping the slag off and going over again to fill in gaps. Another problem was that the steel square tubing has rounded corners, meaning that when a spacer has to be welded onto the upright to make a T, two sides of the end of the spacer are to be welded to the curved corner of the upright, making a big gap I had to bridge across somehow. It turns out that surface tension causes the exposed edge of the metal to pull back when it melts, so I had to bodge little slivers of metal left over from the cutting into the gap to stop this happening, resulting in some ugly welds that I may have to grind flat before I paint it - or to make the surfaces I'm going to weld the rungs onto flat enough for them to go on straight! We'll see.

Anyway, having checked the fit against the wall, I could then finish off the welds on all four sides of each junction, completing one side of the ladder. It's intentional that the flanges point in different directions, by the way - they mainly point upwards so the weight of the ladder isn't pulling them away from the wall, except that the one on the angled spacer has to be underneath so I can get in to fit the bolt, and the top one is underneath so the anchor bolt hole isn't too near the top of the wall:

One side of the ladder

At that point I ran out of time. It won't take me too long to assemble the second side as I already have all the flanges welded onto the spacers (which was quite time-consuming), and I can clamp it all onto the existing side to get the alignment correct without all the cross-checking and measuring I had to do the first time.

After that, I'll need to weld the rungs in place, tidy up the welds, scrub it down with a wire brush and sandpaper to clean off all the welding grime, degrease it with white spirit, and paint it.

Then I need to figure out how I'm going to get it into the wall! I'll need to somehow hold it in place while I mark out the drill holes, which might be tricky without an assistant. Then I have to try to drill the holes where the marks actually are (the bane of my life is carefully marking out a wall, starting to drill, and the bit hitting a stone and suddenly meandering half a centimetre off centre - then having to try and jam a screw in nonetheless, as whatever I'm screwing to the wall has holes in places that can't move to match).

After that, holding it up to the wall and slipping in the anchor bolts should be easy - then tighten them up and I'm done! They have a tightening torque recommendation on the box, so I'll finally get to use my torque wrench, and not be left wondering if I've tightened them enough or risking cracking the wall by over-tightening (which has been a concern with previous anchor bolt expiditions).

Day 1 of making the ladder (by )

This weekend, I am attempting to make a fixed ladder, mounted to the wall of my workshop so I can fix the roof more easily.

First, I had to tidy up in the workshop to make room. I bought a set of four folding chairs for guests which are rather in the way (the chairs, not necessarily the guests), So I screwed a few bits of scrap wood up between the beams to store them:

Chair storage in the rafters

See all that damp on the ceiling, by the way? That is the enemy! Eradicating that is the long-term goal of this whole mission.

With the chairs out of the way, I could get on with the task at hand. Here's the bit of wall where the ladder will go:

The wall where the ladder will be fitted

And here's the pile of steel I ordered from Hindleys to make it from:

A batch of steel waiting to be turned into a ladder

The ladder is being made mostly from 1" square steel tubing, which needs to be cut into bits of various lengths with my trusty angle grinder. Here's the rungs (longer parts) and the spacers that will join it to the wall:

Rungs and spacers

However, for extra strength and extra not-having-a-sharp-corner-ness, at the bottom it will be joined to the wall by an angled spacer on each side. The spacer will be at forty-five degrees to the vertical (and to the horizontal, thanks to the magic of maths), so I need to cut twenty two and a half degree angles onto the bottoms of the ladder uprights, like so:

Angled cut

Also, I needed to cut out two spacers with twenty two and a half degree angles at one end (to mate with the uprights) and forty five degree angles at the ends which will mount onto the wall, bringing my pile of various lengths of steel tube up to this:

Rungs, spacers and the angle spacers

Where the tubes need to attach to the wall, I'm going to weld them to flat steel plates, which will be drilled for the bolts that join them to the wall. All of the tube ends I've cut will be welded, so the fact that they're rough angle-grinder cuts doesn't matter, but these edges will be exposed, so the fact that they are nasty and burred offends me:

Mounting plates after cutting

But a quick run along the bench grinder each has given them nice clean edges:

Mounting plates tidied up

Sarah turned up and took a picture of me, just as I was finishing. Check out my lovely protective clothing - I take my safety seriously when dealing with forces that can make metal flow like honey:

Me in my protective gear

Finally, I measure out the layout of the angled spacer, to check I'd done my maths correctly to make it the right length to produce a 30cm spacing, to match the straight spacers, and that the angles were right:

Checking the fit and alignment of the angle spacers

Tomorrow, I will go out shopping to buy some anchor bolts to mount it to the wall (I can't drill the holes in the plates until I know the diameter required), welding magnets so I can make sure the angles are exact as I weld it together (I don't want a wonky ladder), and some metal paint so it won't rust when it's installed - then it's time to start welding. I plan to start by making the sides with the angled and straight spacers so I can check they align perfectly by placing them one on top of the other, before welding the rungs in between them.

Continue to day 2...

Shemsa’s Dogs and Cats (by )

This post isn't about the big stuff but about one murder and a legacy.

My friend has spent the last year trying to help her friends in Tripoli one of whom was sadly murdered. The lady was called Shemsa and was a kind and loving person who looked after and took in all the strays. Her death has left her friends with the task of rehoming and looking after the animals she had rescued.
