Yes, the metric system, you don’t even need to think, there are 1000 millimeters, or 100 centimeters, in one meter.
In the metric system 3+4=7.
In imperial 1/8+5/32= 9/32.
My choice is clear :)
I started making a bucket for the rear linkage for my Iseki 177. I bought iron doors on Craigslist with a thickness of 3mm (1/8") and 4mm (5/32"). the lower part is made of 4mm metal. Due to the faceted shape, a rigid structure was obtained.
