| The straight red lines show a groove running from end to end (toe to heel) for sliding on coping, rails, or ledges in a 50/50 style. The hourglass red lines depict a deeper groove shaped so as to allow the backside/frontside grinds to lock in, yet not bind while going around curved rails or coping. Also, you can see that only two bolts hold the entire slider assembly together to the plate. I used furniture bolts.
