Hey, Ed. After you wash your hands, scrub them with shampoo. You'd be amazed how much more black you'll get out.

If you can't get one, make one. Hawkeye, proud to be a member of MetalworkingFun Forum since Jan 2013. Thanks given by: EdK

Do we get a hint as to what you are making?
Full of ideas, but slow to produce parts

I made one previously but for some really stupid reason I did not make it to the same height as the compound which requires me to adjust the tool holders in the QCTP when I switch between the block and the compound. A royal pain in the butt because of my stupidity! I machined two sides of the block and found there ware ridges on the surfaces that pointed to an out of tram mill head so I de-condomized the mill and measured the tram. I was expecting the Y tram to be out based on the ridges but it was spot on and the X tram was within .00025" so out of tram was eliminated. Next I measured for jaw lift on the movable jaw of the vise but there was none at all. Perplexing to say the least. So now I'm trying a fly cutter to see if I get better results. To be continued. Ed

Maybe too much play in the ways? New mills have to run in a bit to seat, and then need to be readjusted to eliminate any play.

I've got the gibs fairly tight, but it's worth testing with a DI to see if there's any movement. The fly cutter isn't working too well. I think the geometry of the cutting edge is not quite right so I'm going to put that project aside for now and work on something else until I get the tool ground properly. Ed |
