The design can be inprouved, take a look
http://tinypic.com/view/?pic=im1i7lThere is 2 big problems here:
- strong and right connection between base and absorbers
- strong and right connection between both absorbers and drill suport
Idealy, this connections must be all metall and welded.
Next days I will try to imagine a "in house" strong connection (I
don't have a welding machine).
