My only real experience with a diamond saw (and not much at that) is cutting masonry, and there the more water you throw at it the better. - Original Message - From: "Gene Heskett" To: emc-users@lists.sourceforge.net Sent: Monday, May 9, 2016 10:08:32 PM Subject:

Re: [Emc-users] Cutting cast iron with a dry diamond blade

I am not an expert in diamond sawing, so take that as a caveat. However, as far as I know diamond turning of iron-based materials is almost never done. For iron-based materials the abrasive of choice is CBN. The reason for this is, as I understand it, is because carbon is soluble in iron. In fact

[Emc-users] Cutting cast iron with a dry diamond blade

Greetings all; I just spent the better part of 2 hours, reading just about everything I could find on the care and feeding of diamond edged saw blades. Cutting using them to cut metal seems to be searching for about a 10-33 Tor vacuum. I would think this is a well researched, and well

If you are lacking torque, another option is to only run the tap in to your first peck, then hand tap the rest. There should be enough there to get the tap started nice and square, and M8 taps aren't too difficult to drive by hand with a decent wrench. Adam On 2016-05-07 22:49, Gene Heskett

Well, it looks like they are getting closer to you. http://www.ruralking.com/storelocator/index/index They have expanded rapidly in Indiana. They are like a TSC on Steroids. They also sell a lot of things that go bang. I think firearms is a substantial part of their business. Andy is probably

Re: [Emc-users] 7mmx1.0 decently hard cap screw, how scarce are they?

Gene, Do you have any Rural King stores around you? The local big Rural King is selling metric screws by the pound. A little ironic I think; They should probably be selling them by the Kilogram. ;-) That said; I doubt that they have 7mm screws if they are rare. But I know they have 6 and 8 mm
