Sorry porky I've just made a balls up of your topic. You will need to post it again in the DIY section. Don't ask!! Extreme strawberry blonde moment. Apologies.
You may find that cherry burr is as hard as most woods come and is a delight to work with.
Depending on what you decide to go with if you like I will cut you out a blank of ash burr, cherry burr, yew burr or beech burr, oh I also have some birch burr too.
All seasoned and ready to go with fantastic grains and moulds.
