How thick is the metal that has the bulge? You could nearly cut the bulged piece out with a grinder (being careful with the depth of the cut) then turn the piece inside out and weld it back in. I know it would still take some banging to get the right fit. Decent looking blade though.

Write on another forum, found that small parts as gears and shafts that will fit in a bucket in of all things Vinegar will remove the rust from them.

Thanks D. I use Vinegar currently for anything small enough to fit in a 5 gallon bucket. Slow but does break it loose. I have used a product called Metal Rescue. Very good product.

As to the blade, by the time you spend on trying to salvage the face you may as well have cut it away and replaced it. A daunting task yes but well worth it in the end. Any luck on removing the Gimmy from the frame yet? Having a engine/machine shop fit new sleeves may be your best bet.

A good dynamite man could get the curve back to where its supposed to be, but those days are long...

There is an explosive metal forming technique used for building boats and space vehicles. A sheet of metal is placed over a die (often made of concrete) and an explosive is used to force the metal into the shape of the die. There are variations but this is often done under water.
Or did you mean that I should blow the whole thing up?

No, I don't mean blow it up, you'd need a couple partial sticks, placed properly, tamped properly. might come out bubbly lookin, if the rust behind the bulge isn't removed, first...

I have a similar blade that doesn't angle on my 7. Sorry the first picture is so large. It was taken quite a few years ago when I found it on a prehistoric digital camera. I thought you might like to see how I reworked it for power tilt. The lines are crisscrossed between rear cylinders and the valves. It works great.

I thought I had a better picture of the rear cylinder mounts. Here's the best I can find right now. I made them out of 1" plate and burned them on in place of the turnbuckle mounts.

Once the machine is running and the blade back on, why not just push it into a pile of dirt and see what happens?
