Nice web page. I am impressed with you work.
I downloaded your DXF files and they are well done. I wonder what package you used and if there is any text or dimensions on any of the pages. With all the programs I have tried to read them with I get no test, not even in the bill of materials. However the drawings are all there.
I like the way you mounted the angle to attach the bearings.
As I say it looks as if you do fine work..
