Got the rectangle tubing back from the shop where I used to work. Ron did a nice job of cutting the holes for the rippers to go through.
I next cut two pieces of 1 1/2" x 1/2" flat stock and drilled a hole in the center then welded a 1/2" nut to one side. Then I slipped them into the ends of the tubing and welded them into place. I then cut 12 pieces of 2" x 1/.4" flat stock 1 1/2" long and drilled 9/16" holes in them and welded them into place to hold the rippers. As you can see, I'm not the best welder in town but I live in the country so I can get away with it.
Then I cut a piece of tubing and slanted the cuts to give me access, drilled two 1/2" holes. This will support the ripper bar.
I welded two 3/8" all thread couplings to each side and drilled the required holes in 1/4" end plates and bolted them in place.
Almost forgot, I made a handle to make it easier to move the latch back so I can angle the blade when using it as just a plain blade with the box and rippers off.
I bought a stick of 1 1/2" x 1/2" flat stock to fabricate the rippers. I cut them on my cut off saw except the tips which I couldn't get enough angle on so I cut them with the 4 1/2" grinder.
Then I installed the rippers. I forgot to buy the 1/2" round rod that will hold them in place so I've got them held in with some 1/2" all thread rod for now.. I also need to drill one more set of holes in the rippers to hold them up off the ground if I just want to use the box blade without ripping up the ground.
The only thing left to do is sand blasting and painting. Can't make up my mind whether I want to paint it black or red. Red's always good. Hope I haven't rattled along too long or bored anyone with too many steps in telling how I built this combo blade and box blade. Forgot so I'm editing to include that the total out of pocket cost so far is $40. and change for 1 1/2" flat stock and I think about $6 worth of nuts, bolts and washers. All I have to buy is some 1/2" round stock or 1/2" bolts to hold the rippers in place. I used about 1/2 of a 14" cut off saw blade and 9 cut off blades in the 4 1/2" grinder so you can add another $15 plus power for the tools and welder. Not too bad I don't think. It was fun and finally, The Jewel.
