Re: [ATM] Grinding Machine for mirrors

Hi Russ,

So long as your over arm/tool is able to follow this "floating" motion with
out it affecting the stroke parameters than it shouldn't be a problem, how
ever if you can adjust it out now so that the platter is true to the axel
shaft then it's all the better.

Subject: [ATM] Grinding Machine for mirrors


 
To all on the list, I have been fabricating a Mirror grinding machine.. My
turntable is 22 inch diameter.. The shaft supporting this is 1" tempered
steel. This support seems to be sufficient and does not flex with my wieght
on the perimeter for testing.
     Now my question... On the outside diameter of the turntable, while
rotating, I have a 1/32" up and down "float"... Is this a big problem???  Or
do I need to get closer??
