Dust shields

1/4 inch is what I have.
The reason I have it in stock is I use it for making router templates. It cuts very nicely with sharp wood working tools.

Probably 12"x12" sheets are unsuitable but I'm thinking this stuff should be available somewhere locally without too much trouble . . and it's pretty cheap.

I used 3/32” abs.  It is available at plastics distributors.  It cost about $25 for a 4x8 sheet.  I pop riveted it in place and sealed with black seam seal.
