</font><font color="blue" class="small">( Are you sure about that weight, or is that what the shipper estimated? I got 5 feet of 1"x1" solid steel stock for making the teeth, 5 feet long is 17 Lbs. Then a piece of 3/8"x4"x 10' long that the teeth will be welded to, it is 66 Lbs. Finally a piece of 1/2"x2"x4' for the side piece that ended up being free because they rounded off the weight to an even number. So I think I'm saving about $100. Now someone may bring up that this steel is not heat treated or hardened. That is true, but since the teeth will be pushing into dirt, I don't think I need hardened steel for that. )</font>
Mine does weigh about 150#. A lighter bar may work just as well, and I'm sure mild steel teeth will probably last you a long time in dirt (if not you could hard face them). Be sure to post a picture when you get it finished!
