The crown, or if you like, the spark arrestor

January 28, 2006

I had already finished working on the Shay when I was at a fair in Houten (NL) and stumbled some very nice and fine mesh screen. I bought me a strip (2 meter, it will take me ages to use that up) for a few euros.

At home I put a nut in my vise and filed it more or less round.		I put the nut and the mesh on a piece of soft scrap wood
I used my vise to pres the nut in to the wood taking the mesh with it		Here you can see the impression the nut left behind
Then I cut the mesh more or less to size		I bent the mesh roughly to shape with my fingers
And then with my pliers		The intermediate result
Finally I cut it down in circular strokes.		And now my Shay has its own crown
