Parts drawings for DIY manufacture or reference

Back to change notice
During the years I have the WD16H, and while making this website and answering people on various items I made a number of drawings.
Some people have been helpful in making drawings as well.
Below a survey of the various drawings available. 

I made these drawings on the parts I had at hand and using metric measuring devices. It should always be kept in mind that the original drawings will have given tolerances and as such each individual part has a place in the cloud of tolerance values resulting from the manufacturing process.
I am however fairly sure that with these dimensions you get a useable part.
The imperial conversions I added are always a rough guesstimate as metric values will basically not be in line with the imperial fractions.
