Trivet or coaster

Just using up some left over log slices thought I'd make a set of coasters, then scale up and make a trivet which I cut to half depth, flipped and rotated before cutting the other side (made an mdf blank to hold this in place for that one). Coasters were done at 100mm diameter on 3mm bit with the trivet done at 300mm. Fun way to use up some odds'n'bits I had laying around from felling some trees
