I used a Vinyl Cutter to cut out the logo designs. This could be any design being cut though. It takes less than a minute to cut out but it does take ages to the 'weed out' the stencil. Removing the areas I want to see and leaving the rest.

When I had the stencil done I used some transfer tape to help transfer it to the saw. It gets pressed over the top on the vinyl so the vinyl sticks to it. It can then be peeled of its backing and transferred to the saw. It did stick with some persuasion but not as well as I had hoped. I think the uneven surface of the rust didn't help. Sealing it with lacquer definitely helped though.

To protect the rest of the saw I covered it with transfer tape. This will protect it from the sand blaster in the next step.
