AL- I have been looking at posts in both the Mill group(this one) & the lathe group about mill column stiffining. I gather from the postings that loading the...
Dave, makes sense to me, loose shot should dampen resonances in the column. I think the REX mill has shot that is held in place by Anocast(?) material which I...
I agree- My mill is setting on a 3'0" solid core door on top of a wooden, table height bench I built years ago. My base plate is only 3/8" thick - 27" front to...
Al: One thing to note in how I braced the column is that it is now impossible to rotate the column about the large bolt. I knew this at the outset, and...
My DRO isnt working! The scales work fine but when I hook them up to the display the display wont reconize the scale for some reason... when it does it does it...
Ken. I agree on mounting the work at an angle, not the mill, I never tilt the column. As to the comment on chatter, I work mostly on harder materiels, bearing...
heres the URL for anocast http://www.anorad.com/onlineCatalog/anocastComposite.htm or check http://www.phillyresins.com for the same kind of stuff there is a...
Intresting information. I assumed that Anocast was some propriatary material somewhat along the lines of unobtanium, and did not look further than a Google...
Anocast isn't an option, so there isn't much point in looking at it. I talked with them when looking into these things. Anocast only does it for OEMs in...
I was talking over this type of solution with a machinest co-worker, and he raised the question about whether or not there is the possibility of distorting the...
I agree- As I postulated in earlier post - I think the dampening astion would be maximized if the mass load was somewhat "fluid" - thus the use of BB Shot...
For some odd reason, I have had Grizzly M12 draw bar'd end mill holders on back order for quite some time. Guess I wanted to see if they ever actually got any...
Folks, Perhaps a silly question, where does one find lead shot or bb shot on-line or in likely local establishments? Was looking for some for exactly this...
Don't know that you'll find lead shot other than for shotguns. What is "a tad expensive"? I just bought a 25 lb. bag for $17 at a gun shop. Had to call...
... so you think I oughta stop opening all these shotgun shells and just buy a bag of lead?... Doh! ;-/ Seriously, anyone found a good way to cap off the...
Has anyone given thought to melting down old automobile wheel weights ? They're dirt cheap ( free at the 2 shops I stopped in at locally ) as they aren't...
Might be worth it if you can make shot or very small parts from it. I think a major part of the value of the shot is that it is fluid, not solid, so it...
Not there yet, but I was going to do similar, but use flat head screws so nothing protruded. One mine, with the angle plate on the rear, both the front and...
I saw a post in this or LATHES group about using silicone ???? I'm planning to find a plastic pipe that the pivot bolt will fit thru & slide it up inside the...
I think I'd rather handle filthy wheel weights than dental lead. Tetanus I've been immunized for. What could be on the dental lead I haven't been. Graciously,...
... it. I ... not solid, ... is ... loose ... The value from filling the column can come any of several possibilities. First and most obvious is increasing...
... It is also true that loose material will more readily ... How about concrete with a couple of rebar rods incased? Similar to a highway ramp. Sounds...
On a brake lathe they wrap a large rubber strap around the outside of the brake drum to absorb the vibration and reduce chatter. why not get a couple pieces of...
How does one correctly mount V-blocks and a workpiece on a mill? Do you set it all up on a granite block then transfer it over, or do you "loosely" mount it...
I have never been happy with the way indicator bases set up, particularly on my 7x10. The MiniMill is a little beter, but not much. Seems like nothing ever...
I read about those over on the 7x12 group and just got in the Noga test indicator holder (mounts in the spindle.) All I can say is that I am astounded. What a...
In one of my initial replies, I included a J&L part number, the one from the current flyer. It has permanent magnets, not the kind that turn on/off. Like I...
Here are the two postings I made over on the minilathe group: There are a number of types of Noga bases, mine are the "NogaFlex" (J&L #NOG-10500K). J&L flyer...
