Finally found some time to update and add some shredder issues, I’ve read in some topics.
For “Oldfashioned” countries not (yet) working in Metric.
The rotating knifes and spacer, with a 1″ Hex. Hole. Easier to find in some countries I guess.
And to reduce the lasercosts a little, I took a older prototype frame from the shelf, made from Square tube and some flatiron. Worked well and strong enough, but we opted for the lasered version in the end, because it is easier to align and always square.
The ‘older’ version is also easier to change, being it smaller or wider to Fit when 5 and 6 mm sheet is not available. Do the Math Yourself, and adjust the tubelength a little.
On one side You need to close the gap between sieve and frame with piece of sheet, should be no problem.
