combine this blade with a hitachi chop saw


http://cgi.ebay.co.uk/Hitachi-C10FCB...1%7C240%3A1318

total cost around £170.00 but you could do cheaper by buying used saw
always available on ebay



have used the above hitachi chop saw now for some 8 years and it is still
going strong,havecut aluminium no problem ,havealso used the aboce bladesin
my hitachi circular saw with good effect
I agree a recip would be hard work,i have a hitachi 24volt one and it does
ok within limits.
