Good day,
I'm looking for a straight edge to try my hand at some machine rebuilding, unfortunately in this part of the world it's near on impossible to get your hands on cast iron straight edges. But to my surprise my local tool supplier ordered a Magnalium straight edge for another client and has a spare one in stock. Prices are not that high +/- USD350 for a 1 meter version. From a quick inspection they have scraped surfaces and the specs online do not seem too bad (5μm flatness and 8μm parallelism over the length). These types of straight edges seem to be made in China or Taiwan. My question is, has any one used one of these units, do they hold up (not wear too quickly) and will they work for scraping / machine alignment purposes (carry spotting compound, etc). I am in the process of making a cast iron straight edge from a old casting I have butchered, but my surface plate will only accommodate about 700mm of length and I need something a little longer. Thank you for any info.
Regards,
Alastair
