Cutting/slabbing coral
« on: July 02, 2008, 08:57:13 am »
I got my 10" diamond saw blade running and was going to slab up some Florida coral to Heat Treat it over at Pat's at the end of July. Good lord this stuff is hard. Its like trying to cut it with a soft hacksaw blade. I got about 100# of this stuff. The question is would it be easier to cut it after HT? or do you think it would be just as hard. The reason I want to slab it is to not waste any of it. Anybody got any answers.  :-\

Dick, I think it would be easier to cut after. However, the big concern is that the pieces will be to thick and heat unevenly causing it to fracture or explode. I would hate to see that. If you get tired of cutting that hard stuff you can always send it to me.  ;D But then, if you don't get tired of cutting it you could slab it all and then send it to me.  ;D ;D ;D  ::) Justin

Hey DanaM, yes I do pound on some rocks once in a while. I took a short class with Vinson Minor and he has been there for every question I needed answered. I cannot attach any photos because I get an error message about my "upload folder is full" what ever that is.

Justin, If and when I get it cut etc I will send you some. I owe you for that Obsidian I got from you at Pappys.

It is the folder designated for storage of uploaded files like pictures or video.  I increased the size so you can post pictures again.  Justin

  Dick, If you don't want to wipe your blade out quit now. You need an oil bath saw to cut coral and then it is still not quick. The only way to heat treat it is to reduce it down by spalling, and then it is hard to cut because of the irregular shape. So you just beat it on out.  You have to have an oil bath or a lot of credit at Home Depot for blades.

Thanks Eddie. I probably can do an oil bath with my set-up. I am using a table saw I custonized and isolated the motor from the liquid. I will check and see what oil I have to use and go from there. I have a bunch, small bucket, from Chris that I don't have to cut. I'll take that over with me.

DanaM, your on. I'll save a couple pieces each for you and Justin.

OK Here are the photos DanaM of my first points.

So Eddie, lets say a guy does have access to a oil lube saw.  Do you cut first then heat, or heat then cut? Justin

        Cut then heat treat. Your table saws RPMS are too fast you MUST slow it.

   Yep, just like Brian said. You can go high speed if you have sufficient cooling. Which most rock saws don't have. And the quality of diamonds are not as good as the ones I use getting deep rock cores.

Them look real good Dick!! Don't know anything about slabbing or cutting - have always spalled. Maybe I'll try that sometime :).
