I finally have my new revised plank plug and parting board ready for PVA and then first mould half. It has about 5 coats of wax as seen in the picture. Along the way, I had a house breakin and the kid damaged the plug by spearing it into the ground. Fortunately, it did not do much damage, and I was able to repair it reasonably easy. The police found the kid and return other stolen goods!
