Last year I put up one of them concrete walls, where you put the post in then slide the slabs in. What I want to do now is remove the gate and put slabs there to as I have 2 gates. Where the gate was I used the posts without the grooves, to save taking them out do you think it would be possible to use a grinder to cut grooves into the posts to slide the slab in, then at the top of the post where it may look abit untidy mortor it flush. As it getting painted I do not think this would look bad. Just need advice on what you think about cutting groove in post with grinder ?
Thanks
