Could a badly pitted 12" wide steel bar be polished by dragging it behind a tractor? I know that the leading edge would be tapered but that could be burned...
What is the end result your wanting? Appearance or function? I guess this would be more of an orchard grinding than the more usual Blanchard grind, depending...

I have bored and rebuilt at least 200 engines. In the worst of them the bottom of the cylinder has little to no wear, less than .010". However the top usually...

Thanks guys I got the crazy idea from looking at plows being trucked between farms. Several years ago I bought a cheap piece of steel bar (yes, long ago there...
Hello Pat Here's an idea, just mount some 1/4 in strips about 1 1/2 to 2 in wide down each side to slide on ? It would have less friction than the whole plate....
Dragging a plate across the surface of dirt could take forever. Add some weight and it would probably get shiny but not flat. The process of dragging something...

Dear David H I to have been wanting to find plans for a Mill, a bench mill actually. I have shied away from a full size multi-machine so far but that may be...
Thanks Darwin This seems to me at least, a very big deal. If boring the block was impossible, 2 simple and short (3"?) sleeves could be made out of something...
... Pat, On the original MM, didn't you have a big ball bearing mounted to the block? With a sleeved shaft and a cutter, I bet a boring bar would be pretty...
