Hand Tools
What design tolerances should be allowed for something being made using hand tools?
I'm designing a product for the developing world, and was just wondering what tolerances could be achieved if it is designed to be made exclusively using hand tools e.g a band saw, drill press and hand saw.
I'm thinking it could be in the order of 1-2mm? But any ball park figure based on experience or otherwise would be much appreciated!
for hand saw cut (6.3 - 50 micron )
band saw cut (3.2 - 50 micron )
drill press (6.3 - 25 micron )
use design data book of engineers
