@Vorange. I'm expecting the performance to be quite similar to the existing model, if there is any change it will probably be to run a little hotter as there is a very limited amount of metal and no contact with the wood to leach off the heat. @jardri. Your WW is made from Sapele, an African tree in the same family as Mahogany. The leather bottom came from a back patch off a pair of jeans. I do volunteer work in a charity shop and saw the patch on a pair of jeans going out in the rags, so I snagged it and recycled it.
