Hemispheres and Cones

So today I made yet another maquette, this time I got the theory right and the measurements approximately so and what I now have is just about a hemisphere, made out of card looks like a lampshade but I now understand pretty much how to get what I want.

There is a problem however, since I am interested in the live edge effect of the acrylic and the brightness of this effect seems dependant on the surface area of the face of the material each hoop will have to be at least a couple of cms on the face and ideally quite a bit more. 

The diagram shows that the ability to use concentric circles to do this and thus avoid material waste is much reduced when you get to the largest.  I think I may need four or five sets to get the requisite diameters and double this to make the sphere.

I think that I may try to make a more or less full sized maquette out of Correx and in any case I have several things to do: -

  • Consider what full size would actually be, with reference to cost of materials and the largest sheet size the laser cutter can deal with.
  • Think some more about the best way to get least wastage
  • Cut some samples of increasing face width to see where the increase in edge lit effect with increase in face area seems optimal in terms of material use/wastage 

Cost Benefit analysis in Art what is the world coming to?

"Hylas was one of the Argonauts who sailed with Jason in search of the Golden Fleece. When the adventurers harboured at an island Hylas’ task was to search for fresh water for the crew. He found a gladed spring and was filling his pitcher when he was encircled by water nymphs. Hypnotically, they drew him into the watery depths and although his friends searched for him, Hylas was never seen again.
In Waterhouse’s hands, a myth explaining the drowning of a youth amongst sinuous lily leaves and stems, becomes an evocation of sensual female flesh, an immersion into the deadly allure of the femme fatale.”

On making mistakes and making the same mistake twice.

The first photographs in this post are not mistakes, I now have two refurbished luminaires just lots more to go but at £10+ a pop for the bulbs will be doing it piecemeal. (Pop, bulb, get it?)

Now to the mistake part, I have found a relatively cheap supplier of live edge acrylic sheet and have in mind to make a large spherical piece out of laminae separated by gaps.  So what we have in the photographs is a maquette of concentric circles each two cms smaller diameter than the one below it and overlapping by one cm the gap between each one being 1 cm, with sufficient gaps to get the radius of the sphere. This repeated 1 cm up and 1 cm in gives a constant angle of 45 degrees, not the formula to get a hemisphere and I should know this having made exactly the same mistake trying to make a sine wave and ending up with a saw tooth

Tomorrows task then is to make another maquette where the gaps between laminae are still 1 cm but the diameters of the laminae are set by the width of a hemisphere at the relevant point.  I have no doubt that there is a way of calculating this, there must be since it is possible to plot the graph of a circle but I will draw it and measure the drawing.  I could of course use concentric circles as above but then I would have to vary the gaps between the laminae and I think this would look strange.  

Learning point, my late father-in-law was a joiner and used to say measure twice and cut once, in this case by making the test pieces I have wasted some time and two sheets of card rather than twenty quids worth of acrylic.

Nice lampshades though.

This is the kind of Youtube advert that I would like to see more of.

You know how it is, you go to YT to look at a vid for something and an advert comes up and as soon as you can crash out of it you do.  This started and I watched all five minutes of it, it’s actually an advert for Come to California and to Siverdale in LA in particular.  

There are people who you think I would go for a beer with this guy and here’s one, Adam Tenenbaum.

One of those rare days when things just seem to fit.

Photographs: -

  1. The bulb I have been waiting for had been delivered to the wrong address and now to mine, tested the wiring and put the bulb in, fiat lux.
  2. Three hundred watts even with the sun shining through the skylights casts a good shadow on my Kirigami architecture.
  3. Solvent welding Perspex works really well when you have a good area for the joint, less so when only a couple of square mm, so used glue
  4. Second one made up and shown with first
  5. As above
  6. Turned the lamp onto the sculpture and look pretty shadows and projections.
  7. When you get the right angle all you see of the orange is the edge
  8. Other way round and light on, interesting mixture of real and projected
  9. Oblique view to show shadow/transmission

In spite of suggesting that everything went well today it did take me all morning to glue these things together but I am really pleased with how they have come out. 

Laser Cut Perspex 

This is my acrylic ziggurat made from Perspex lamellae, the individual slices are not glued and so the conformation of the object is fluid.

Photographs one, two and five the step is on two sides and the other sides are aligned.

Photographs three and four this should perhaps be called a taruggiz since it is an upside down ziggurat bowl shape that balances relatively easily on the less than one cm square smallest piece until of course you come to pick it up.

Points to consider: -

I think perhaps I need to duplicate it so that I can put the lid on it as it were, or better yet make it out of concentric circles to form a hollow sphere.

I accept that there is an aspect of naff tastelessness in this suggestion but cut in the yellow edge lit Perspex it would absolutely shout at you.

I want to look at lighting it with lasers and projecting onto and through it, things to play with next week

Wildlife in Salford, and believe me there is some wild life in Salford.

Needed some glue the other day, to stick stuff with not to sniff so I walked over to the shopping precinct and on the way came across this bracket fungus growing on the stump of a tree, I believe it to be Chicken of the Woods fungus which is apparently edible very tasty and can be frozen, needless to say I am not going to risk it although apparently it is one of the easiest edible fungi to identify and has few poisonous look alikes.  

A New Perspextive on Positive and Negative Spaces.

My mother always used to tell me that sarcasm is the lowest form of wit, so I imagine that my sort of pun sits just a little above that.

Today has been really very good, it is remarkable how much work you can produce in a couple of hours, if you have the help of an expert (thank you KZ) and several tens of thousands of pounds worth of equipment.

Photographs 1 and 2 simple geometric positive and negative space shapes cut from edge lit Perspex, these will be assembled into free standing sculptures when they have been cleaned.

Photographs 3 and 4 I wanted a series of concentric rectangles so that they could be assembled into a ziggurat and it turns out that there is a lower limit to how close together they can be cut without the Perspex slumping because of the heat.  This is a series of frames which are too warped to be stacked square and so have been rotated by about 45 degrees per step, not unappealing.

Last photograph, with about 10 mm between each cut the material stays rigid and flat and can be stacked squarely, so we have a sort of ziggurat or step pyramid of which more later.

Kirigami Architecture, an opportunity for OCD

Some while ago a Foundation tutor said to me “Paul I think you need to look up Process Led Art”.  When I did I recognised certain aspects of myself and the way I make work.  

Sometimes I will start something knowing full well that I will feel obliged to finish it, even if this means spending ten or twenty hours doing a repetitive task such as drawing bricks.

  • Photo 1 Decided to try to make a factory chimney and ink the brickwork, cobbled it up due to perspective issues and not being able to count
  • Photo 2 Second iteration, much more thought gone into this one will take several days to finish
  • Photo 3 Detail of above, 400 bricks down about 10000 to go

This when it is finished will be a fudge, the taper in a factory chimney is due to the fact they are narrower at the top, compounded by perspective since unless you are a steeplejack you always see them from the bottom looking up.  This flat kirigami drawing has the same number of bricks at the top as at the bottom just reduced in size for the single point perspective that I have used.

I don’t really have OCD just a few minor tendencies in my process but having lived with someone whose OCD was pathological have the utmost sympathy for sufferers and collaterally damaged bystanders.

Ferengi - The rules of acquisition.

  1. If you are in some fashion disabled you may wish to consider not spending your hard earned money in Hyde in Tameside.  I know that local authorities are strapped for cash but this stinks.
  2. When people say I’ve got these things and I am throwing them out you say “Yeah I’ll have ‘em, I can fix those.
  3. Consider re-purposing, large surface area desk made from notice board.  NB it is a known fact that the larger your desk and the less it has on it the more important you are. (C.f. fast cars and the size of ones penis, note that while I now have a large desk the importance factor is reduced significantly by the amount of crap on it!)
  4. New bit of flattened kirigami architecture, looking at perspective, this is single point, and drawn on.

Parallel Evolution: Kirigami Architecture

If you look for examples of Kirigami you will find that they  are usually based on cutting across a fold and the base of the piece is a 90 degree angle a little like a book half opened. This need for the angle means that the pieces must either be shown in the corner of a room or on a table or shelf.

I have discovered that it is possible to cut this original fold and overlap the paper such that much of the original structure is preserved in 3D but the backing sheet is now flat and the object can be shown on the wall as a relief.  There are obvious restrictions which I need to understand better for example after overlapping the paper is no longer square and has to be trued and I need to find a cleaner method of making the joint in the overlap.

In the nature of these things, when I think that I have had a fundamental insight and invented something new I find in a few weeks or months that someone has done it before me, which is why this post is titled Parallel Evolution.

I don’t really see myself like this, I’m not quite so good looking.

Photographs 2-4 Positive and Negative space,testing different materials, aluminium sheet and white emulsion.

Seems to work well, the camouflage of the white and the reflections of the shiny side add to the effect. Shall make some more of this material up tomorrow.
