On this forum a while back, we were discussing sharpening, and one fellow insists on doing his with a file........good grief!
Hey, I resemble that remark!
I know if you put heat in it you lose the temper, for those that claim they are not building up heat, touch it on your arm after you take it off the wheel, belt, disc, etc. I bet it doesn't take long to move it!
For those of you that have a heat treat furnace, disregard the above comment!
I worked at a striking tool manufacturer long before I got paid to use those striking tools, I've spent many hours grinding, polishing, coloring hammer heads, picks, axes, pry bars.
Heat softens the metal which in turn takes the temper out of it.
One example, I worked as a maintenance carpenter at a major window manufacturer that constantly put tape on the floor to designate where different items needed to be placed, make improvements on location and remove the tape to be put down somewhere else. They would use 4 and 6 inch floor scrapers to remove the tape, the employees would bring the scrapers to tool and die and myself in the carpenter shop. Tool and die would use a right angle die grinder to sharpen them, spinning at 8, 10 or 12 thousand rpm, they would blue the edge every time, edge wouldn't last long until the workers were expending more effort to scrape up the tape. I used a file to put an edge on the scraper, it would hold the edge longer resulting in less effort. I wasn't long that I was getting all the sharpening jobs.
It's six one way and half a dozen the other, put heat in it and sharpen them more often, take the extra effort to file and balance them.
I'm positive that the factory uses coolant when they put the initial grind on them.
I'm sure a Bradley or something similar will be on my bench one day but with a good file and the blade in a vise, I'm still capable of getting the job done.
Oh yeah Gene, I'm really feeling for you getting the stone to the nose!!
Different strokes for different folks.
Enjoying the read.
