plane is roughly level. Lay the spirit level across the two rails and level them using the levelling feet. Now put the spirit level along one rail and adjust the support rod to 2. 3. level the rail. se on the rails at the support rod end and mark its position. Then make similar mark 1.2 meters along the rail. easure up from the bench to the underside of the front rail at each mark and record the heights a,...
