***This post has absolutely nothing to do with wood but hopefully it is interesting enough to read anyway ***
I’ve decided to try something wacky and build my own lawn aerator. In addition to poking some holes in the grass, I am hoping that it can smash down the mole tunnels at the same time due to the weight of it after it is filled with concrete. Best yet, I nearly have all the stuff laying around that I need to build it except a piece or two that I can pick up at the local Home Depot… or salvage from my brother’s scrap steel.
I’m sure the design isn’t the most “safe” configuration, but we’ll let the moles worry about that.
I used a drill equipped with a fairly small bit and randomly drilled holes all around the concrete form. I am not too concerned about the cardboard deteriorating. I figure I have the nails embedded deep enough that they won’t slip out on their own. Here’s a view from the top to give you an idea of what I mean.
In order to prep the cylinder for pouring I cut a piece of rigid foam into a circle and marked the center. I stuck a piece of 1/2″ CPVC in the center of it, pulled it out and then stuck it into the concrete form.
Here it is flipped over and ready for the concrete to be added. I also made another circular foam cutout to hold the top side of the CPVC in the center.
I moved it outside and grabbed the concrete bags out of the garage. All the stuff I’ve used so far has been leftovers from other projects. I prefer to ignore the fact that I may have “over-purchased” on previous jobs and choose to believe all the stuff is “free” at this point. 😉
Here it is with it chalk full of concrete and the top foam piece in place.
I ended up buying a small ball hitch and a piece of round rod for the axle and welded it all together in my brother’s garage. Unfortunately I didn’t take any pictures over there during the assembly, but next post I make, I’ll try to take some of the finished product and have it hooked up to my riding lawnmower.
