Just where do art forms and mantlepiece trinkets stand against the necessity of keeping warm?
These lumps are thick with knots and branch roots and in the main from diseased and fallen trees. Some might make interesting patterns in a bowl, but at prices most people would walk away from. Witness the craft stalls packing up their pieces at the end of another day, and the tat that people would prefer to accumulate from car boot sales.
What pieces were re-usable were set aside for future gate posts - I live on a farm (not mine).
Place your bids?
Consider also, that much of what is shaped into 'craft', gets swept up or recycled as firewood when the cleaned up portion is sliced into a turnable shape. When split to burn - nothing is wasted. This wood is unfit for furniture making, and much would be turned down for lathe work. There was some Ash in there, but held a wasps nest. They were not happy either.
Couldn't find that thread yesterday Mick... Some true beauties there and I've now added mine to the collection 
Those size logs can split a bit explosively at times 
I normally process between 1 - 2 tonnes a year and those machines are a godsend
