Blanchard Ground Plate Question

Feb 09, 2004 4 Replies

I have a need for a couple of reasonably precisely ground surfaces. The metals dealer in my area sells an 8" x 8" x 1" Blanchard ground plate for $23. A couple of 4" x 8" pieces would do me quite nicely.



Can I cut an 8x8 Blanchard ground plate in half (using metal cutting bandsaw) to form two 4x8 pieces without encountering some sort of internal stress induces distortion of the precision ground surface? I'm assuming the Blanchard ground plates are formed from hot rolled steel which would tend to minimize internal stresses, but have never worked with them.



Any thoughts/advice appreciated.


I've cut big holes in larger plates of Blanchard ground hot roll than what you're talking about without encountering any problems, but there's probably no sure thing here. How flat do the plates need to be when you're done?

As long as you don't cut it with a cutting torch you should be ok.

I want to put three feet on one side and set my machinists level on the top. The combined apparatus will be used to check a section of I beam that I will be grinding and scraping flat for a project I'm working on. So, the flatness needs to be close enough so the machinists level won't rock.

--Sounds massive if you're using steel. FWIW TCI sells blanchard ground aluminum plate. Neat stuff...
