Default The box blade

I've just about completed the box blade. A big thanks to soarkrebel for the plans. I followed them pretty close and adjusted as needed. I have 3 decent scrap yards within 7 miles of me so I lucked out and found everything I needed. All told, including nuts, bolts, and pins I think I have $250.00 into it.(not counting consumables)

1. I found a 4x5x3/8 piece of tube steel. My little saw cut it, but it took 33 minutes
2.and 3. I marked out the slots for the scarifiers and cut them with the plasma cutter.
4. and 5. Decent scarifiers are close to $40.00 apiece so I made my own.

Looks good so far!

Do you have any plans to hard surface the ripper teeth? If so, I'd lean toward doing the leading face, so the material behind would wear away and make them self sharpening.

I didn't notice if the cutter bit ends up at an angle? For efficient action, I'd think you need 30 - 45 degrees.

Digr suggested a brilliant way to cut the 3 x 1/2" steel. I did just like he said and cut a slot across the center, leaving about 3/8th on either side.

1. The only measurment I messed up was the first one The box should have been 20" tall and 24" deep. Somehow I cut the plate 20x20. Dang math
2. The cuts across the center.
3. The first bends.
4. Me
5.The second bends. I was really pleased they both came out so close to each other. Thats the beauty of Digr's idea.

No camdigger, they're flat on the bottom. I'm planning on putting the ripper tips on. I had to guess at the angles though so I hope it works.

1. The first rough fit.
2. Drilling the first of a lot of holes. Starting with a 1/4" bit and stepping up to a 3/4" was the best way to do it. A lot of bit changes but worth it.
3. and 4. Again, I'm amazed at how well I could duplicate the bends. Pretty slick Digr
5. I welded the cuts with 7018. Root pass and then a nice big bead on top.

Nice work, Bender. Did you have to weld the slits closed, from both sides of the bend or just one?

Those slotted/welded bends turned out really well.
Looking good Bender.
