I hoped to build my plinth at home in North Wales over the Easter holiday, thinking that having family around to help would lessen the stress of building my first construction in wood. As it turned out, the plinth I had in mind would be too long to fit in the car boot (rookie error) but luckily there was still time to order materials to CSAD. Having planned out compositions before the holiday, I came up with the design on the right to begin with, an upside down U shaped structure with hollow legs, a cross between a white plinth and a high table. I had trouble figuring out how the legs would attach to the top however. On a visit to Huws Gray building suppliers I came across the cross sectioned 4.3cm lengths of wood which I thought would make much more graceful legs.
As a result I adapted my design to the one above, a rectangular box with 15mm MDF board on top. Nigel suggested I would need supporting struts around the middle to support the weight on top but thinking this would disrupt the minimal aesthetic of the ‘ghost plinth’ I compromised instead by decreasing the length 30cm to 140cm (which as it turns out, is more than enough space). I used half-lap joints on the corners, like a canvas structure to strengthen the shape, cutting these on the bandsaw and joining them together with two 100mm screws in each. The MDF top was stuck down with a nail gun. I didn’t use glue for the leg joints which means the plinth can be taken apart, transported and re-assembled for other exhibitions, really handy!
The biggest worry was that after assembling the structure was very wobbly. Thankfully this was mainly to do with the timber being warped rather than my own shoddy building technique. Next time I would drill the countersink holes deeper since lots of my screws sit proud of the surface and this made it hard to cover then over with polyfilla and paint. I’m glad I left a centimetre ledge around the edges, the shadow underneath creates a nice sense of lift for the top which will frame my pieces. I’m very pleased with my design overall too. I wanted my pieces high up but a big narrow conventional plinth would look like a wall, bulky and jarring in a space which is light and airy. Hopefully there will be some visual dot the dots between the extruded forms in my work and the square cross-section frame. The bars across the bottom are great too, they stop the structure looking too much like a table while also adding strength and stopping people getting too close to the plinth.
My plinths are also partly inspired by coming across the work of American artist and professor Peter Christian Johnson on Instagram. The plinths that have been made for his ‘Acts of Contrition’ series are beautiful but complicated architectural-looking assemblages of square cross-sectioned wood. Having looked further into these and looking back at my own design I realise I could have been far more playful with the structure, creating shelves of different height on which vessels could sit. The plinth itself becomes a container in some way then, carrying on the thread of the vessel theme into the whole of the composition itself. Having no experience of building with wood this was beyond my capability but now I have some knowledge of the jigsaw puzzle that is building a piece of furniture, I can be braver with my plinth designs in the future.
