Default your thoughts on metric

I am getting a bit fed-up with the 15/32...13/64... and the rest of the crap
measurements we use here. Why shouldn't I go to what the rest of the world
uses? Metric. Please no political BS. Seems like using 10's is a lot
easier.No I'm not too old to change (62).G


Getting a Festool DOMINO forced me into metric. Thinking in metric took
a while - 25.4 mm/inch a became one of those numbers to add to my
instant recall list - which includes much harder to remember 7 and 10
digit phone numbers, PIN numbers, drivers license number, license plate
numbers etc. No big deal.

After a while I thought and calculated in metric when using the DOMINO.
And calculating mainly in integers is a LOT easier than with mixed
fractions.
The DOMINO cuts mortises for loose/floating tenon joinery. When
you're playing with mortise and tenons joinery, lets say for a table
apron
to leg joint, you want "outside faces" either flush or "set back" some
specific distance. Working out where the center of the mortise in the
leg should be, and where the center of the tenon, or the center of the
mortise, in the end of the apron should be - in order to get the outside
face flush, or set back a desired distance - can be "challenging if you
use "imperial". MUCH easier using metric. Here's a link to a page
that shows what I'm trying to describe.

If you do ply "case work", there are several metric systems - and tools
- to make producing parts quickly, accurately and efficiently. The
"32 mm System" has been around for quite a while - for a reason.

If you do solid wood furniture, and mill your own stock you don't need
imperial or metric. If you need something to be "this tall" - you mark
a stick for "this tall" and cut the needed parts "that long". If you
need something to fit "between here and there" you use slip sticks
to get "this wide" or "this long" and cut your parts "this wide" and
"this long". No numbers at all required. And it's easy to find the
centerline of a board. All that colonial furniture was done without
measuring tapes or rulers, divided into 32nds or 64ths.

I'm still using imperial, but the DOMINO is changing that.
