Just spent most of today doing this, in between visitors… overnight setting but still nice and soft to carve… in a twist of the unfolding it’s now not for the bronze ‘sunwheel’ – clients want a smaller one for that… will buy this one as well for a different site… with whatever feature I come up with… including carving…so I went for a celtic knot plus some branch hints and on one side a medallion probably to have a celtic knot in it too…

Note the tungsten scraper and also the steel ruler which scraped at an angle around the spiral helped true up the curve.. on a boat hull this is I believe called ‘fairing’ the lines. Also for carving the knotwork I found it helpful to paint primer on first so it is easier to draw and see to cut to the lines… More work needed but at least main carving done while plaster is softer. Tomorrow it will be harder. ..but still ok to scrape with tungsten blades.
