This isn't the first time I've looked at building a belt grinder 
Last time I got stuck trying to find the right size cold rolled steel. I did find some 2.5" x 0.5" but the price was ridiculous, so I looked for metric bar and just couldn't find what I wanted.
The metric equivalent of 2.5"x.5" is 63.5mm x 12.7mm
so 60mm x 12mm cold rolled steel so do ............. just couldn't find any. 50mm x 12mm is common but that makes the "sliding bar" a touch on the small side.
Strange as it seems most (not all) of the aluminium is in inches they designate it in mm such as 25mm x 3mm but it is 25.4mm x 3.175mm (1" x .125")
I might look at making it in aluminium. If I can find some 63.5 x 12.7mm or 60 x 12mm may do.
Failing all this I'll just go and buy one.
