Greetings everybody; When I was making the adaptation of the er-40 adapter, I first reground the spindle bore to a short MT5 since it was bent and had about a 7 thou peak to peak runout at its mouth. That runnout fix seems to be good yet although its possible there is an error in the taper, thanks to the bed wear. So I next made from an 8" rod of decent alu, and MT5 + threaded spud for the drawbar to grab, all this working several inches away from the spindle nose, and with the rod chucked in a 4 jaw, running within a half thou of true. Turned it around and seated it in the spindle, then cut the female of a 5C on the other end. So far, so good, everything running about 1/4 thou of true. Bought an MT5 <-> 5C adapter from Grizzly, set it on the end of my alu "jig" and trimmed it short for the spindles 1/2 MT5 socket, even put a lock pin in it to lock the er-40 to the 5C adapter. Today, I knocked it apart because I could slap the er-40 about around by about 4 thou and cranking on the drawbar wheel didn't help. The upshot is that I can seat the 5c adapter pretty snugly, hit the front flange with a dead blow, and knock it sideways by that same 4 thou.
Took it apart, ran a green scotchbrite pad soaked in thinner into the spindle and wiped out any dirt that cut loose. Do the same with the OD of the 5C. Not quite lox clean but close, and it appears the real error is the taper on the OD of the 5C. I used exactly the same math to polish it as I used to freshen the spindle bore. But first I've either got to make a new jig, or fix this one as the taper that mates with the adapter is now rigid, but running out by that same 4 thou. The only 2 things I can see that would have caused that is the diff in the MT5 tapers because the carriage was sitting about 8" down bed from where it was when I made the spindle run true. Bed wear, sure as hell. I've ordered two of the laser sighting cartridges, one for my 6.5 Creedmoor, and one in 38 spl which I'll chuck in the ER-40 kit to make this bed wear comp measuring thingy work. =================== I tried to get cheese to work on the pi, but the dependency's demand a newer kernel, and its pinned. So I'll have to drag an x86 machine and monitor to the lathe to run the laser rx stuffs. An old Dell, it runs cheese just fine. Fun and games, but after the weather settles from Florence I expect as I'll have to rig a table for that stuff behind the lathe, and that may demand an open garage door. I didn't try v4l though, should have. Installed it, recognizes the camera and all its controls but cannot start a preview. It says its using mplayer2 but I don't know if thats installed. Not, being installed now. but that gets me a green screen and no further ssh traffic. Time for a powerdown reboot of the pi, it may have run out of memory, despite have several gigs of swap mounted. Sigh, quit trying to make it act like a big machine, dummy... Florence should be history I hope with no deaths by the time the lasers arrive anyway. I'm close enough (3 blocks) from the river so I expect some high water, but not enough to reach my lot. If it does, "biblical" will not be adequate to describe it. FEMA says they are ready, but this rodeo will be the usual repeat. You can't change the spots on that Leopard. Stay dry, those of you on the right coast. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
