Yeah I'd considered jazz's vertical design but going to go with the standard horizontal set up as it will better for setting up the jobs that I will be cutting.

I should have the "finalised" model up pretty soon so all comments will be welcomed as I will start ordering materials and components soon after.

Just a quick question on fixings, is there any reason why hex cap head bolts (with counterbores) are commonly used over hex head countersunk bolts? Is there much difference in strength or is it just personal preference?
