Re: Milling aluminum

I expected so. But surprisingly enough, my wash down bottles sit right on the mill table by the vise, and right on the flat cross slide of my lathe. Neither bear any appreciable scars, though they have undoubtedly been hit by blue hot chips may times. It seems that unlike other surfaces (top of my s...

Re: Fly Cutter Problems

Assuming alignment or flex issues have been eliminated, your bit may be ground wrong for a fly cutter. A fly cutter bit is quite different from a typical left hand lathe bit in that it needs more clearance on the end, and the feed is toward the end, not the side. So the edge on the end is where you ...

Re: Milling aluminum

I prefer to use the laboratory type wash down bottles. They sit upright with no seams below fluid line, so no worry about leaks. They have a bent straw coming out the top with a tiny tip for very precise application of small amounts of lube. I've got them for various cutting and lubricating oils. An...

Wow. I use mine all the time. Wood work, fabrication, and machine work.

Re: Does Dykem go bad?

Happened to me too. I've got some red that seems to be holding better, but I don't use it that much. When it dies I'll probably just use markers.

Re: CCMT recycle face mills

No idea on his claim of movement, but I've never noticed a properly seated insert moving. I also prefer the insert retention with the eccentric pin, a top finger clamp, and carbide "anvil". I tend to think of Kennametal for those, but I've seen that mechanism on others. Other than a few carbide bori...

Re: CCMT recycle face mills

I had this problem; some automotive gears I repurposed were so hard, I couldn't get through with carbide. Yeah, the one I did was broken in the spline only leaving a little to remove (something less than ~0.200), and it beat the crap out of the insert. But it was able to get it done without anneali...

Re: CCMT recycle face mills

Yes, I do feel like the roughing tool I'm using for that obtuse angle holds up to the abuse better. However, I haven't seen or done a side by side comparison or any supporting documentation other than the general position that wider angle points hold up better than more acute angles. After all, that...

Re: CCMT recycle face mills

If your lathe can run them, and you do a lot of steel as I do, CNMG is nearly impossible to beat on cost per corner, plus great deals are plentiful. Years back I bought a box lot of CNMG at a sell-off auction, something like 40 lbs of premium brands, more than I'll ever use. Edges come out to litera...
