Sealdaddy, thanks again. So I had this Texas agate on the saw, I wont say how many hours it took for the first cut. Read your link again and took the blade out. Checked the arbor for play and the blade for dishing. Then I read the same thing that Redrummd had told me about the hammer treatment for sharping . Well, not counting remounting in the rock grabber, the second cut took 8min. and 36 seconds. Boy do I feel dumb. I am going to have that little hammer gold plated.

Red bricks & Cement  burn off the kurf on the blade. It is the sides of the blade that cut the rock............

  Though best to ware the rap off the back side of the diamond in the slot of the..... BEST to use a 220 grit wheel....

  In my 45 plus years of lapidary sawing.. i only use 220 grit wheels. and MODOC cy. ca. obsidian why. smile on face as i redress my blade 18'' star blade / same as a MK- 297. just painted Blue........ the last blade to re-dress.

Some blade makers will fix a dished blade for a fee.  If you know it's dished, I would contact them first.  Fixing a dished blade sounds easy but takes skill to anneal and temper a blade.

I'll pond out the edge of a blade with a no.2 file. Then it's a large Brazilian agate to re-dress the blades cut. Or high speed through a 220 grit wheel.

Ok, I think the author meant a fire brick to dress the saw.  Either that a brick of SIC you get at most lapidary distributors.  I have never used fire brick to dress the my diamond blade, and are ones you get at Home Depot appropriate?  One other thing, water cooled units builds some kind of gunk on blade edge quickly, and causes the blade to be frequently dressed.   What about oil lubed units?  Dressing needed or as frequent.  I have used mine on some Tiger Eye with a so called "hard stone additive" from Covington.  No problems.  Cuts just fine.   

One more, please:
I need some advice about the frequency or other criteria for changing the reservoir oil in my Star 10" which I love.(BD/ MK bought the company out)  The thing is a horse.  I left my oil in the reservoir (garage) to get out of PHX in the middle of May as the heat will wear you out.  I got back this week, and although the oil needs some topping off, it looks fine, but once again changing the oil is not brain surgery.  All opinions are welcome and received with heart felt thanks.

The link no longer works and instead goes to some overseas Casino in some other language.
Sad really, it had been a very helpful link before.
I am going to unsticky this topic since it no longer is working.
