That would not be a worry, since the compound has been replaced by a substantial hunk of cast, found in a sprue cut off a white truck wheel hub. We have a casting place here in town that makes those wheels. That cut off sprue weighed around 40 lbs, so I found other parts hiding in it too. :-) In my case, its the lack of meat in the cross slide its bolted to with a couple armstrong bolts. The top of that cross slide is a scant 1/4" thick. And the armstrong bolts could easily bust out a piece of that casting if a serious leverage to the side were to be put on it. That won't happen on my watch. > > On Wednesday, June 10, 2020, 3:33:24 PM MDT, andy pugh > <bodge...@gmail.com> wrote: > > On Wed, 10 Jun 2020 at 20:33, Gene Heskett <ghesk...@shentel.net> wrote: > > That would nice but I'm not 100% sure my bxa post could handle a 50 > > lb chuck 2 feet out of balance. > > That's 100 ft.lb. A good heave on a long spanner. Would you expect > that to break your toolpost? Nope, but whats under that elevator block replaceing the compound is another weak point if serious leverage were applied. > > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
