A neighbor had a moving sale/auction I got some walnut 18"x12"x3" three of those nearly that size plus much cherry and maple, and a lot of for oak for $5 , I waited after the auctioneer asked for a bid, no one said anything so I said $5 and got it all couldn't believe my luck.
what i have found with spirals is I have to cut slooow so i can be accurate and keep moving, if i stop i have a tendency to make a little "nub" cuz it doesn't take much to move them off the line
well i have a couple sheets of paneling that i just hate to throw away, tried to make some ornaments today, thought i'd glue them reverse "to hide the blue flowers" but they came out so fragile i think i'll see how many BTu's i can get out of the firepit this weekend, hey i tried recycling!!
