I needed to get the most accurate guide holes for the legs, I could have hauled out my radial arm drill but its such a complicated piece of equipment to set up and confirm it is actually set up correctly I really couldn't be bothered for just one hole as a reference.
So my trusty PARF system was my choice I needed the drilling block to get the most accurate guide hole in both legs.
I guess I could have popped in a few dog holes as its a dog ramp after all
