Guys, just an update, I absolutely love my sand box target. It's holding sand just perfectly, no leaks anywhere. I've already shot the same carbon arrow, Easton Camo Axis, with field points & muzzy broadheads at least 100 times no problems of wear at all. I exclusively shoot a recurve and/or a longbow, but the trailer behind the target is empty, noone will be in there, but I always check the area before I start shooting. Anyway, I definitely encourage you to build one, if your looking for something that you can't EVER wear out. I guess I might have to add some sand in a year or so, but that might be 1 bag which is $3.87 at Home Depot. In my area 1 ton of mason sand is $12/ton, had a landscaper deliver it for $20
Would love to see other's ideas & finished projects. Also, no cats yet, they know better than to come around with My two 80 pound Wimeraners just waiting for a furry meal.
