[Healeys] Heat Shield Material

[Daniel and Diane White]

Dan,
When I made my heat shields I used the cement board.  I got it from a 
local tile shop, used my old heat shields as patterns and cut out the 
new ones with a jig saw.  It may be that one cement board is more 
brittle than another depending on the manufacturer...you may want to 
check out more than one supplier and compare the boards.  My material 
cut and drilled w/o splintering or shattering.  I clamped a yardstick 
onto the board and work table to guide the jig saw so my edges are nice 
and straight.  I don't think you want the material too soft because 
inevitably it will get dented if it is.  I can send you pictures of the 
heat shields if you need them.
