Sunday I removed all the old bolts holding the blade on the frame. I had sprayed them about a week ago with some kind of penetrating oil. One came loose and off real easy, another 2 broke when I started putting toqure on them, a forth I cut off with a sawzall.
Monday I had to many other irons in the fire to mess with it. But Tuesday I made up my mind I was going to take thre bow out and reweld the rib that was on it. then reinstall it on the frame with all new bolts.
I wasn't able to get all the bow out by laying it on a couple blocks of fire wood then putting down pressure with the Botas bucket and bounceing it a couple times.
The brace rib was broke by one of the mounting bolt holes and I was not able to get it straightened out with the tools I have at hand.
I got a 4' piece of angle iron (why they didn't use angle iron for the brace to begine with is beyound me.) marked the frame mounting holes on it. Took it inside to the drill press and drilled four 1/2" holes in it. Returned to the blade and bolted the angle to the rib which did straighten it out some better(LOL) than it was. did some tack welds to tie the two together and welded a couple beads on the rib to the blade.
Got it mounted to the frame but the orginial holes would not line up on the bottom side since the angle pushed the blade back an extra 1/2". I go get my Hitichi corded drill I bought because it is a hammer drill at a resonable price with great reviews and I needed a hammer drill to do some concrete drilling. Set it to the non hammer mode and it powdered thru the angle and rib real well. It runs at high speed, but is variable i need to learn how to trigger it. the second hole I got thru the angle before I had to quit work on it for the day.
So today if not raining I will finish the hole and add the last bolt. then all that is needed is another guesset plus fix the 3d link hook up so I can use the standard QH 3 link hook.
Plus once the weather is a lot warmer a paint job.
