Thanks George,
I have a copy of the article and started to model it in CAD before attempting to build one but found that it had many missing dimensions. The smaller parts are excellent and fully detailed with drawings and photos but the main structure (base, tilting table, etc) have incomplete details with only an outline drawing. No dimensions to position of holes, etc.. The size of some parts are hand drawn on photos or referenced in the text or not at all.
I have worked as a design draftsman for 40 years and can piece the parts together. But someone with less experience would have trouble, which is why I have asked if anyone has made the grinding holder.
Paul.
