No 150mm is way too big, 75mm would be max I'd go with, 50mm better. Don't be put off by the tapping, the thought of it is worse than the doing. Plus you don't have to tap every hole straight away, could even just tap every other hole and use the others for dowel pins for fixture guides etc. This is where a matrix really comes into it's own because it's very flexible.

Tap the Bed not the spoil board. You'll be cutting into the spoil board and slowly surfacing it away.
