We Love Sugru (by sarah)

We love Sugru which is a putty like stuff that you can form into shapes, sticks to just about everything and is flexible - it is basically a funky silicon rubber from my understanding. When we first heard about it we couldn't get hold of any and so had to wait as they had sold out but the wait was worth it!

Since then we have used it for tonnes of things from embedding electronics in hair pieces, making creatures for the visually impaired, fixing fridges, shoes, adding little feet and buffers to all things electronic, fixing broken mugs and making jewellery. I plan to fix my electric guitar with it though need to see how it reacts to having glitter added to it!

But it is more important to me than it's usefulness. To me Sugru represented something more, when it appeared I was struggling with both scientists and artists telling me that there was no cross over between the two areas. My tag line o twitter is that I am The Artist Scientist or Artistic Scientist and to see this product - the result of something an artist (ok design student) had produced, being so wonderful for science/tech and artistic endevours.

This was the sort of fusion of art and science that I was sure should exist but was being told didn't and my examples of how the modle builders of film dinosaurs had ended up solving the mystery of joints and movement that paleaontologists has been struggling with was falling on deaf ears.

So I turned up at The Cheltenham Science Festival debate on science verses art that year with my sugru bracelet and my ESA t-shirt I'd won for Celestial Montage and found that people didn't seem to really cae on either side of the divide, they have their opinions of the others and that is that. Stuck in the middle as all ways I gritted my teeth and looked for more science-art related things and found it under the title science communication.

Recently Sugru posted their life story so far and asked what inspired others, so I told them - they inspired me! They provided the evidence I needed that science and art can create wonderful productive and helpful things by learning from each other, they are an example of a dream that was followed and they provided the very material I had been trying to work out how to make myself - I was mucking around with resins casting, silicon mould making and fimo in order to get something like sugru and I was failing and could not make the projects I wanted. I hadn't even thought of applications beyond my own ends and there WOP! appeared sugru ready to go and so I went and so did Al and he has even written up one of his repairs/hacks for their website!

The Sound Panel (by sarah)

It a year of fiddly work but there is a sound panel complete with sounds of space, slime moulds and cracking ice to name some of the eight.

It is obviously not a full sound cave but it a proof of concept and a piece of science-craft in its own right. It could not have come about without the aid of ESA, UWE, Ella Matthews and Alaric. Not to mention those who sponsored the project so that we could actually buy the components without them there is no why I could have afforded to make this.

For the next week as part of National Science and Engineering Week it will be on display at Centre Arts in Cheltenham.

Sultanas (by alaric)

THE SCENE: Jean is eating a chelsea bun.

JEAN: "I don't like sultanas."

ALARIC: "They're... really sad to hear that. They say they tried as hard as they could to be tasty for you."

JEAN: "I absolutely hate them."

ALARIC: "Oh no! Some of them are crying now!"

JEAN: "Well, I'm eating them anyway."

ALARIC: "Ah, that's cheered them up a bit!"

JEAN: "What, even though I'm killing them?"

ALARIC: "Oh, you're not killing them, you're liberating their trapped souls."

JEAN: "Really? Well, they'll just be 'tanas' then, without their 'souls'."

Unsigned Sessions and Mention the Bear (by sarah)

Me and Alaric finally made it out to see some live music - something which has not happened yet this year! We went to the Unsigned Sessions at The Playhouse in Cheltenham. These are run by The Record Shop down by the Norwood pub.

It was the first time we had been in The Playhouse which has a nice light fitting I took photos off to try and sort our how my camera works! I only found the black and white setting after the gig!

The first band was unfortunately ill but a young guy came on and played some cracking tunes - I can't remember what his name was unfortunately.

We then got a band called Red Shift who were a three piece band, a guitarists with two guitars, a saxophonist and flutist in one and the dude at the back with the squeeze box who I unfortunately was not in the right place to photo.

They played some lovely covers - some of which had a depth the original songs never had.

The guitarists voice put me in mind of David Bowe meets Pink Floyd with a little Bon Jovi thrown in.

My one issue was I felt the Gnarls Berkely cover needed more energy, but having it sung by a warm female voice was genius 🙂

Then we got on to our friends' band, Mention The Bear, they were doing a 68 Come Back Elvis Special with guitar cases for percussion and more guitars than you can shake a stick at!

There was some serious hand blurring on the fret board happening and Richard did not disappoint with raw performance - if Elvis and Jim Morrison had had a love child... just watch the video I took!

Neither the film nor photos are as good as I wanted as I was just mucking about with settings to see what I got and some of them I didn't realise weren't quiet there until I got them up on a computer screen!

See guitar case drum!

Guitars galore!

Dan rocking out!

Richard absorbed by the music.

Jumping around time!

I was really happy to have an chance to wear my fifty style skirt I made last year (with modernish heavy metal themed material!) and my ancient blue suede boots 🙂 Though I am still disappointed there was no black leather!

Day 4 of making the ladder (by alaric)

I wasn't scheduled another project day until later in the month, but I had some spare time and the opportunity to grab a volunteer (my father in law, Len) to help, so yesterday I mounted the ladder on the wall!

(Background: Days 1, 2 and 3).

The first step was drilling the holes. I held the ladder up against the wall, and checked it with a spirit level, while Len pencilled the holes in.

Then it was time to drill. I'm very fond of my SDS+ drill (as I have mentioned previously) so it was good to have an excuse to get Vera out again:

Without further ado, I started to drill:

However, disaster struck on one of the holes - the bit suddenly went sideways, into some kind of void inside the concrete blocks of the wall. Doh! I fitted a smaller drill bit and managed to drill back into the route the hole was supposed to take, then drill that out so the bolt could go in straight, but now it was in the middle of a much larger hole than intended so it would just rattle around and not hold anything.

Thankfully, I over-engineered the design so that it had far more mountings to the wall than it really needed, so none of them were all that critical. What I did was to jam a piece of wooden dowel into the misaligned part of the hole to fill much of the space, then squirt a load of fine mortar (2 parts sand to 1 part cement) into the rest. More on that later.

With that done, I could fit the anchor bolts to the ladder. The anchor bolts consist of a normal-seeming bolt that goes through the ladder, into a sleeve that goes into the wall. The sleeve is a metal tube, but at the far end is a conical nut that the bolt screws into. When the bolt is tightened the conical nut is pulled into the metal sleeve, forcing it to expand to tightly squeeze against the surrounding masonry.

So to start with, I put all the bolts through the ladder and screwed the sleeves on a few turns to hold them in place:

Then we lifted it up and guided the bolts into the holes and wiggled it into place. Of course, as it's nearly impossible to drill holes into masonry accurately, the holes were a few millimetres out from where the holes in the ladder are, so beyond a certain point the bolts started to chafe against the masonry and had to be tapped into place with a mallet:

All except the hole packed with mortar, of course, which the bolt just slid into squelchily.

Then we tightened the bolts - all except the one in the wet mortar; I'm going to give that a few days for the mortar to cure before I tighten it, otherwise there's no resistance to the expanding sleeve and it'll just squeeze the mortar out.

And then it was time for a test.

After gingerly doing a few pull-ups on the ladder, I climbed onto it. And then to check it's really secure, I put as much strain on it as I could by stretching myself out to get the maximum torque:

This failed to tear it out of the wall, so the next step was to actually climb up to the roof:

See how the top rung protects the gutter? That's careful design, that is! 🙂

However, it was cold, damp, and slimy up there, so I climbed back down and had some lunch. After lunch, I put some sealant around the edges of the mounting flanges, to prevent water getting in behind them where it might soak into the wall through the bolt hole, or lurk around and make the flanges rust. Also, I like sealant and will use it whenever I can:

This stuff is "frame sealant", which is specifically designed to join metal, wood and masonry outdoors, as opposed to the stuff you use in your bathroom. It's extra sticky to bond to awkward surfaces and extra stretchy to account for thermal expansion differences.

I also cut some small cubes of wood and pressed them into the open ends at the top of the ladder, packed with plenty of sealant. I tapped them in with a hammer to about a centimetre below the open end and squeezed more sealant in on top, and domed it slightly to keep rain from pooling.

Now that ladder is done, as soon as I get some time I'm going up there to secure part of the plastic sheet that's flapping up, and have a general poke around to see if I can find any holes to seal. With more sealant! Yay!

Also, I need to touch up the paint on the ladder in a few spots where I dinged it moving it around. Whoops!
