I've seen a lot of people recommend silicone spray to go with their diamond paste. Is there any particular kind that is better? I see a lot of them on Amazon but I haven't seen any non aerosol, which I prefer. Do you know of any?
I just got a new leather spin on. I have diamond spray. Do I also need extender with the spray?

I've been using this for my silicone spray. It's aerosol...so not exactly what you're looking for...but just showing you what I've been using. Question...I've never heard of "diamond spray"...what the heck is that??  |

The spray is graded diamonds in a liquid so you just spray it on. But, it impregnates the wheel, so it lasts a while. I wanted spray extender, so I don't have to spray diamonds every time. You can get it in many places. I got mine from JB. |

I think it would depend on what the carrying solution is for the diamonds. You can use the bottled extender fluid and just put a couple of dots of it on the disc if you needed to. Kingsley has it the cheapest, I think. As you work the stone, it will smear the extender over the disc. |

I'm not sure that spray diamond is going to be the best choice for a spinning leather disc.
The diamond paste, also known as diamond bort, is traditionally diamond in some type of grease. Diamonds cling to grease and grease clings to leather. So it's a good match-up for leather or canvas resin discs/belts.
But the diamond spray is usually just diamond mixed with alcohol and I believe a very thinned oil. While it is used by barbers for sharpening razors and by people sharpening knives on leather strops, in those cases the leather isn't spinning at a high speed. I could be wrong but I suspect the diamond spray won't have enough of a bonding agent to stay on a spinning leather surface for very long. Diamond spray is used in faceting which is done at lower turning speeds than for cabbing and the pressure of the stone being polished against the lap embeds the diamond into the surface of the lap (usually copper, tin or zinc) and once embedded the metal then holds the diamond particles in place.
Another option would be the Pandimonium Universal Base Diastiks made and sold by Gearloose Lapidary. These are diamond in a soft wax binder similar to a soft crayon. These diamond sticks can be used with water or oil as a lubricant. I use the Diastiks for faceting and a little goes a long way. I have never tried these on leather but I do believe that with their wax binder that they may adhere okay to leather. And when the leather needs a little moisture a spritz or two from a small atomizer bottle of a very thin mineral oil like trombone oil would probably do the trick. A lot of faceters including myself use trombone oil as a less expensive alternative to extender fluid.
Also I used to know of a guy that would mix diamond powder with Vaseline to make his own polish for faceting. Vaseline may have enough cling to work on a leather disc. And would not be terribly expensive to make.
