I need to hit the gravel driveway at my lake cabin with Roundup a couple of times each summer season to stay ahead of the weeds. I’ve done it with a hand-pumped 4-gallon sprayer but that can get tedious.
I bought a cordless weed sprayer last spring when Harbor Freight had a really good sale.
I was going to make such a thing and had even started to gather parts, but I couldn’t pass this one up. It uses the same battery as the cordless chain saw I keep at the lake. It’s meant to be backpacked, but I thought I’d rather pull a little cart around like a carryon at the airport rather than hump a backpack. Been there, done that, got the DD-214 and I’m claiming OFP – old fart privilege.
Here’s the cart, ready to go to the lake to take my sprayer for a stroll. It’s made to fit the sprayer. I’ll secure the sprayer to the handle with a nylon strap or bungee cord.
I’m proud of the TIG weld on the 45 degree angle in the handle. This conduit wall thickness is about 40 thou. I’d ground off the galvanizing so as to avoid breathing zinc vapor whilst welding. After more than two decades of getting it wrong, I’m finally starting to get it right and I’m shickled titless about that. Stack o’ dimes hell, I’d call that stack of nailheads.
The axles are stainless steel so they won’t rust. I had some ½” stainless rod stock in the goodie box and I’m not getting any younger. The plastic wheels are from Harbor Freight. The tow-handle is ¾” EMT (electrical metal conduit) from Menard’s. The bottom part is ¾ x ¾ x 1/8” hot rolled angle. The visible gray parts were spray-painted with rattle-can instant cold galvanize paint that I’ve found to prevent rust on steel objects for decades. The front “foot” is heavily zinc-plated on the bottom couple of inches because paint there will surely wear off quickly when it touches gravel. I didn’t zinc plate the whole foot because zinc gets burned off where any welding is done.
The sprayer will (I hope) sit in the bottom rack, secured to the post with a nylon strap or maybe bungee cord. The sprayer is at the lake so I won’t know if this actually works until I get there. I did try to measure carefully, but we all know that doesn’t always guarantee success, right? I’m pretty sure it’ll work.
