I actually just made one last week, but won't get to try it for another month.
Anyway, there was a piece of mesh metal scrap at work that got my wheels turning. It was probably about 1.5 ft x 1 ft with fairly small holes in it, but seemed to be thick enough to be useful. I bent it to roughly the shape of rakes I've seen online. I then put a piece of sheet metal on each end. I put a strip of sheet metal across the bottom and top on the leading edges, which I riveted to the sheet metal ends, and to the screen. I then put a second strip of sheet metal further back on the top side. I used a piece of electrical conduit (approx. 3.5 ft long) for the handle, flattened about 6 in. of it which I riveted to the rake. Also, prior to attaching the conduit, I bent it to make it easier to handle from a standing position. I'll try to post a couple pics for you.
Oh yeah, I also drilled some larger holes in the screen to hopefully let sand out more easily, but small enough to not lose too many fleas.
I used to always make my own gear when possible, but a lack of time has gotten the best of me. I loved that feeling when something I designed, constructed, and used was a success. Well maybe again when retirement gets here.
The Device You Are Showing Will Catch Enough For For A 100 Anglers, They Will Die Before You Use Them.
42 Years On The Ocean Front, I Use A Quart Plastic Bucket With Two Inches Of Sand And My Hands To Catch No More Than Six Fleas, Cause They Will Die Unless O2 Nated In Fresh Salt Water , On The Beach I Dont Have A Areated Bucket For Sand Fleas. If You Start Using This High Production Capture Equipment There May Be None Left For The Rest Of Us...........................................
Conduit handle, 1/4" regular mesh screen from the hardware store, and a 2" x 1/8" x 4' piece of aluminum strap material. This rake is 18" wide but I only drag it along the surf for a short time so I don't catch too many. The screen has lasted 2 seasons and still looks good. I rinse it off as soon as I get a chance after every use.
